How to securely attach a suction cup to your windshield. How to glue the suction cup?

Car gadget holders are most often attached to the windshield using “suction cups” with a plastic clamp that prevents the vacuum membrane from losing pressure. For example, a video recorder, radar detector, tablet with navigation maps, or other mobile device are hung on them. However, due to dirt on the glass or due to inhomogeneity of the rubber, the suction cup peels off, and the large console, along with the gadget and wires, flies to the floor of the car. This is unpleasant, since to re-install it you need to stop at a special place to rest or taxi to a gas station, which is associated with a loss of time. In addition, a dropped tablet can break or distract the driver from the road. How can you attach the console more tightly to the glass so that it lasts for several days?

Why doesn't the suction cup hold?

On sale you can find suction cups made of silicone or rubber. But the material from which they are made has virtually no effect on their wear and tear.

Both silicone and rubber Velcro begin to fall off the glass over time:

The service life of the device depends on its quality. Velcro with uneven edges or a rough surface will begin to fall off almost immediately due to the presence of air underneath it.
Dirt, wool, glue particles or other irregularities on the glass will also prevent it from attaching tightly.

How to lubricate a suction cup mount so it doesn't fall off in the cold There are a lot of negative reviews on the Internet about unreliable suction cup mounts. Indeed, because...

Types of suckers

As I already wrote, there are usually two or three of them in the mount to better hold the gadget.

And there are single, but massive ones. They are made mainly from two materials - rubber and silicone. Rubber suction cups are dark (often black) in color, but silicone ones are often transparent.

There is a lot of debate about which of them is better. However, in my experience, the regular rubber options held up better. Silicone hardens much more in cold weather, which makes the suction cup less elastic.

Although to be fair, it’s really difficult to choose between these two options! Because there is high-quality silicone, and there is low-quality rubber.

General principles of fastening

It will be possible to securely fix the suction cup if two basic conditions are met:

The surface on which the suction cup will be located must be flat and smooth.
The suction cup itself should not have obvious defects on the inside.

Basic principles of fastening:

Surfaces must be cleaned and degreased. This applies to both the mounting location and the suction cup itself. Dirt, dust, soap and lime stains, rust and other contaminants will not allow the suction cup to attach firmly. As for degreasing, for this purpose you can use detergents, soap solution, and alcohol solution.
It is necessary to glue only a dry suction cup and only on a dry surface.
Under extreme temperature conditions, increased loads on the suction cup, and also if the surface for fastening has a non-uniform texture or unevenness, you should use means to improve the adhesion of surfaces: Vaseline, self-adhesive PVC film, silicone sealant.

Advantages of attaching objects with suction cups

The main area of application for objects that have a suction cup for attaching them to a smooth tile or glass surface is the bathroom or kitchen. If previously, almost the only accessory that could be stuck to the wall using a suction cup was a hook, today the list of such items is quite extensive and is constantly growing. On sale you can find the following products with suction cups:

hooks;
soap dishes;
glasses for toothbrushes;
shower head holders;
toilet paper holders;
towel holders;
decorative items;
shelves for bathroom accessories and cosmetics.

Most often, suction cups are used in the bathroom.

The growing popularity of products with this type of fastening is due to a number of advantages that the suction cup provides:

a soap dish, hook or any other object can be quickly, within a few seconds, attached to the desired location on the ceramic lining;
In order for the device to be securely held on the tiles, the use of mechanical and electrical tools and drilling of walls for installation of various brackets and clamps is not required;
if necessary, the product can be easily dismantled without leaving traces and transferred to another location;
small price.

What can help?

There are several available tools that will help secure the device efficiently.

But no matter what product is used, first of all it is necessary to thoroughly degrease the surface to which it will be attached.

As a treatment agent, you can use nail polish remover, alcohol, glass spray or soap solution.

Silicone sealant

In order to properly secure the suction cup, you can use transparent silicone sealant. To do this, sealant is applied to the concave part of the device, after which it is pressed tightly against the glass.

But before using the Velcro for its intended purpose, it is recommended to wait 24 hours for the sealant to dry completely.

Garlic juice

You can also securely attach the suction cup using garlic juice. When it gets into microcracks, it clogs them and thereby prevents air from getting under the device.

Simply rub the surface of the Velcro with garlic juice and attach it to the glass, pressing it down for a few minutes until it dries.

Oil

Machine oil or any vegetable oil applied to the surface of the Velcro helps to secure it for quite a long time, acting in a similar way to garlic juice.

In this case, oil is easily removed from the surface of the glass using a regular soap solution or organic solvent.

Car camera

As you know, a new suction cup always holds better than the old one due to its rigidity.

But there is a way to return the device to its previous strength using a regular car inner tube or any other rubber:

To do this, you need to cut a ring from the chamber, the diameter of which will coincide with the size of the suction cup.
Place it between the plastic and the sticky surface.
An updated item can be treated with oil or garlic, then it will definitely last a long time.

Recorder bracket repair

There are often cases when the suction cup itself becomes unusable: the plastic pin holding the “hat” breaks. This happens if you remove the DVR and pull it by the body without being careful.

One way to fix it is to smear the pin with superglue, but the connection will not hold for long, sooner or later the “cap” will fall off. The easiest option is to buy a new mount, but you can still try to restore the suction cup; repairs will cost much less than the purchase. Let's look at how you can repair a suction cup with a lever:

disassemble the bracket - use a Phillips screwdriver to unscrew the screw and remove the cap;
remove the pin;
dismantle the spring and the rod with the broken base;
Using a 3.5 mm drill, we drill a small hole in the body of the rod (in the place where the lower part of the suction cup was attached);
we clean the area, take two wide washers, coat them with glue and place them on the sides of the rubber diaphragm;
take a screw or self-tapping screw 10-12 mm long with a countersunk head, also apply glue to it, screw the fastener into the drilled hole;
remove any remaining glue from the outside and let the structure dry;
we assemble the bracket - put the spring in place, connect both parts of the device, fix the pin;
if the suction cup has a large free movement, it will not press well against the glass, in this case we cut out an additional elastic band for it;
We put the cap on top, assemble the holder completely, the work is finished, the mount can be used again.

Thus, you can restore almost any bracket for a DVR; the procedure takes little time, and there is no need to buy a new holder.

Laundry soap

If the “suction cup” falls off on the way, and there are no special products at hand, then you can use regular soap. You need to moisten it a little with water, rub the rubber generously and wait until it dries. When the soap acquires viscosity, you can attach the membrane to the glass and tighten the console clamp. The soap will set and prevent air penetration, like a thick sealant.

How is the DVR bracket held in place?

A “suction cup” type fastening element is held on the plane due to a pressure difference; when a silicone or rubber circle is flattened on the surface, a reduced pressure is formed inside it. But the bracket is fixed only when the material is absolutely sealed and no outside air gets inside the circle. If there is even a microscopic hole in the rubber band, there will be no suction effect, such a holder can be safely thrown away. The suction cup can only be secured if it is completely sealed, and you cannot press it and immediately release it, in which case it is guaranteed to fall off.

How to attach a suction cup to a windshield

Lubricate the suction cup with soapy water. Our grandparents also used this product to attach soap dishes and toothbrush holders to tiles in the bathroom or kitchen. But do not overdo it with the quantity, otherwise you will have to wipe off the stains formed on the glass;
If the silicone suction cup becomes stiff and loses its properties, they can be easily and simply restored. To do this, it should be dipped in a hot solution of baking soda and allowed to “cook” a little. After some time, it will return to its original plasticity;
degrease the surfaces using a cotton swab soaked in an alcohol solution or simply use commercial wet wipes, then lubricate the suction cup with motor oil. You can use something else (sunflower, for example), but it is the motor oil that has low evaporation in the summer and is less susceptible to freezing in the winter. Waterproof silicone grease has similar properties;
Suitable for those who have had trouble with the suction cup on the road, especially in frosty weather, and are unable to carry out the above-mentioned manipulations. To improve the grip, hold the detached suction cup near the switched on stove for a couple of minutes. This will help eliminate small cracks at the junction of the glass and the suction cup, through which air enters.

Methods to help securely attach the bracket

There are methods that help to secure the suction cup more securely, here are some of them (as car enthusiasts advise):

warm up the fastening element by bringing it close to the heater fan, while the car interior must be warmed up;
use double-sided tape;
coat the contact surface of the bracket with silicone;
cut a rubber gasket along the diameter of the circle and place it between the glass and the holder;
To seal, add a little glycerin to the contact surface; you can also use laundry soap and garlic juice.

Not all of the listed methods work 100%, and there are side effects. The adhesive tape holds up well, but in the sun it heats up and loses its properties. An additional rubber gasket helps in many cases, but you just need to take into account that the DVR becomes a little heavier, the load on the bracket increases (it can break), and adding rubber is pointless on suction cups without a lever. Garlic juice always helps, but not everyone likes the smell it gives off. A solution of laundry soap gives a good effect, you just need to take one thing into account - until the soap has dried, you can move the suction cup on the glass, then everything will set tightly. Silicone should be spread in a not too thin layer, evenly, its disadvantage is that it sets well only after a day; if you drive the car right away, the fasteners may fall off. Another drawback is that the silicone-lubricated holder moves across the surface.

Tips for different types of surfaces

Different types of surfaces, for example, tiles, plastic, glass, have some nuances in the process of gluing the suction cup.

Tile

Most often, it is on the tiles in the bathroom that you have to glue a variety of hooks, shelves and holders. In order for the adhesion of the suction cups to the tile surface to be as effective as possible, you should adhere to the following recommendations:

Ventilate the bathroom if it is damp.
Prepare the surface of the tile by washing it thoroughly, for example, using dishwashing detergent or ordinary soapy water. If necessary, additionally use alcohol-based degreasing agents.
Wipe the tiles dry.
Place the suction cup on the tile and press it firmly.

Important! Do not overload shelves and hooks. Try not to pour water on the area of the suction cups, as the weight of the water may cause the suction cups to move or fall off. If you need to glue the suction cups inside the shower stall, use transparent silicone sealant, this fastening will be more reliable.

Plastic

To properly glue the suction cup to the plastic, you need to pay attention to the surface. If it is smooth and even, then there will be no problems with fastening. © https://ydoo.info/qa/kak-prikleit-prisosku.html The algorithm of actions is simple:

Surface cleaning.
Degreasing.
Suction cup gluing.

If the suction cup needs to be attached to a car dashboard and similar surfaces where there is a “pattern” on the plastic, it is best to use a special suction cup with a lever, which during the fastening process creates a vacuum under the suction cup. Conventional suction cups do not adhere well to textured surfaces; they must be additionally secured with self-adhesive PVC films.

Glass

How to properly attach a suction cup to glass? It is this surface that causes the most problems. Thermometers attached to the window, as well as holders for video recorders on the windshield, very often fall off due to exposure to high temperatures in summer and low temperatures in winter. Attaching suction cups in an aquarium causes no less problems. It is quite possible to securely fix the suction cup if you follow the recommendations below.

What should I do to solve the problem?

Based on the reasons given above, let's consider what can be done to prevent the DVR from falling off:

If you find a defect on the new suction cup (external defect, cracks, tears, uneven surface, etc.), return the device under warranty. Such a bracket will not hold the DVR properly. Or buy a new one.

Of course, installation of the mount is carried out strictly according to the instructions given in the service book. Below we will also give a universal algorithm;
The glass or mounting surface must be perfectly clean and dry. It is advisable to wipe the windshield with an alcohol wipe;
Strong heat can soften rubber or silicone, and cold, on the contrary, can make it “oaky.” As a result, the elasticity of the material is impaired, so the suction cup of the DVR does not stick to the windshield. Carry out installation at normal temperature (room) of glass and air inside the cabin. In winter, it is better to drive the car into a warm parking lot.

If the rubber does not hold the main structure due to the uneven surface of the windshield (for example, it is silk-screened, cracked, chipped, etc.), alas, you will have to look for another place for installation. It will not be possible to create an ideal vacuum on such a surface.
When choosing a third-party bracket, make sure that it fits your DVR exactly (weight, area of the suction element, etc. properties).

How to securely glue the suction cup?

How to reliably glue the suction cup “tightly”, but without using any “superglue”? The advantages of suction cups are that you don’t have to damage the walls, you don’t need to nail them down or drill holes for them. Suction cup fastenings provide convenient installation, ease of adjustment and easy disassembly. The reliability of the retaining element is affected by such points as:

the quality of the raw materials from which the suction cup itself is made;
presence of defects on the suction element;
total weight pressing on the suction cup;
the structure of the material on which the Velcro item should be located.

It often happens that on the concave side of the suction cup there are various defects in the form of tubercles, seams, microcracks and other flaws formed during manufacturing or transportation. Such moments do not allow the Velcro to stick evenly to the surface, so after a while it falls off. If a seam or other protrusion is detected, the layering should be immediately carefully removed with a blade or utility knife. Cracks and breaks are difficult to repair, so it is better to immediately replace the suction cup. The structure of the suction cup must also be correct and even.

Another circumstance that prevents the suction cup from sticking tightly is a rough or embossed surface. If the tiles are made with patterns or non-uniform texture, then the fastening element will not be held. Also, glue particles, various seam putties and the joints themselves are not able to hold the suction cup.

Fixation methods

Various fixing methods can help solve many installation problems. All devices will do their job efficiently and will hold the suction cup if all the above and below conditions are met.

The most common methods of strong fastening are:

use of a degreaser;
use of products containing petroleum jelly;
lining made of self-adhesive PVC film;
silicone sealant.

Whatever option you use, you must initially prepare the surface for high-quality gluing. The action is to treat the area with any degreaser, it can be nail polish remover, acetone, a special degreaser, solvent, white spirit and the like. If you don’t even have a single alcohol-containing product on hand, you can wash the surface with ordinary laundry soap, then rinse thoroughly and wipe the desired area dry.

The method with cleaning liquids is suitable for items that are light in weight and size. The main thing in this process is to thoroughly clean and then degrease the tiles or tiles. The surface should be cleaned of any contaminants such as rust, soap smudges, limescale, dust and other dirt. After thorough cleaning, you can degrease your surface, and at the same time the suction cup. After these procedures, you need to firmly press the suction element onto the tile. Usually this works and the suction cup stays on the desired area. If it is necessary to move the decorative stand, the surface near the suction cup should be moistened. The suction cup will slide perfectly along a wet wall to a more convenient place for you and you won’t even have to peel it off.
The Vaseline method improves the adhesion of Velcro to a smooth surface. This option is even suitable for use in an aquarium with water, where there is also a need to secure an object. In addition, Vaseline is absolutely harmless to fish.
A lining made of self-adhesive PVC film is suitable for medium-heavy interior items. Decorative elements are often attached to the bathroom not only for washcloths or toothbrushes, but also to hold towels, hair dryers and other heavier appliances. Self-adhesive is often included with modern accessories, and if one is not found, it can be purchased at an office supply or hardware store. You need to take the size you need or with a reserve, cut out circles from the film of the appropriate size and glue them to the tiles. After this, you need to remove the protective film and attach the part using suction cups along the contours of the self-adhesive.
An effective and best method for holding heavy loads is silicone caulk. It provides strong adhesion between two surfaces and is indispensable in case of uneven tile structure. For better and more accurate gluing, transparent silicone should be used. Before applying the sealant, the tile and the inside of the suction cup should also be cleaned and treated with a degreaser or alcohol cleaner. After this, a generous amount of silicone must be applied to the concave side of the Velcro and pressed very tightly to the selected surface. Don't worry if excess sealing paste escapes outside the suction cup. Traces of such glue can be immediately wiped off with a cloth. Or after the sealant has completely dried, it can be easily and simply removed using a stationery knife. For high-quality gluing and drying of the silicone, you must wait a day before you start using the hanger, shelf or hook. Once the sealant dries, it can withstand heavy robes, towels, or even heavy appliances. Subsequently, you don’t have to worry that the suction cup will fall off and fall along with all the bath accessories. If necessary, the mount can be quickly dismantled using a regular knife.

The ultra-modern vacuum suction cup is now in great demand. Due to very tight contact with the surface, a certain vacuum is created, which does not allow the Velcro to simply come off. But these suction cups, no matter how popular they are, are able to withstand moderate loads. For heavier items you will also have to use the above options.

Installation from the street

Installation of elements with suction cups on the street side also requires certain fastening technologies. Weather conditions, temperature and humidity play an important role in this matter. Basically, thermometers are attached to the outside of the window to monitor temperature indicators. Also, the density and quality of fastening depends on the type of thermometer: the more expensive it is, the better the suction cups or adhesive base will be.

In order to properly glue the thermometer on the suction cups so that it does not fall off, you should select models that fit your window. For example, there are many modern electronic devices for plastic windows, which, if they fall, will cause a lot of frustration due to the loss of such an expensive accessory.

The thermometer you purchased with suction cups or Velcro will not take much time to install. But how long will it hang around before it decides to come unstuck? The methods below will help you place the thermometer firmly to prevent further chances of falling. Also, when installing a thermometer, it is very important to adhere to certain rules so that it shows the correct data.

The location for attaching the thermometer should be chosen so that it is at an equal distance from sources of heat and cold. The heat can come from both the sun's rays and the opening part of the glass unit. A favorable place for the device is the north side.
In order for the gluing to be as tight as possible, the device should be installed in warm, dry and not windy weather.
As in previous cases, the glass should be thoroughly washed and then treated with a degreaser.
For good vacuum suction cups, a firm hand press is enough to ensure that they are “tightly” attached to the surface.
If you are afraid that even with high-quality suction cups the thermometer may come off and fall, use PVC film as an additional connection or regular double-sided tape.
You can also use a colorless sealant, but in this case it would be better to fix the thermometer on plastic rather than on glass.
Since double-glazed windows come into contact with dust and water on the outside, many people decide to use “superglue.” When using this liquid, you should monitor the volume of glue poured. For good gluing of this substance you need very little. It is also recommended to use this option on a plastic frame.

When choosing an outdoor thermometer, it is better to give preference to simple and reliable models rather than “souvenir” products. Such instances often fail in the indicator and are generally unreliable. Of course, if there is a storm outside with hurricane-force winds, then the thermometer may only be held in place by metal fasteners in the form of self-tapping screws. But in all other weather conditions, suction cups with additional fixation will easily cope with the task.

Attach to windshield

You can attach a video recorder, navigator, telephone, radar detector or other gadgets necessary for the driver to the windshield using suction cups. Attachments for gadgets are usually glued to several small ones or to one large and massive suction cup. But, as practice has shown, any suction cups, even with levers to enhance the vacuum, tend to fall and cause great inconvenience to the person driving, and even while moving.

There are only two types of such suction cups: rubber and silicone, and it is very difficult to judge which is better, because it all depends on the manufacturer and the quality of the product. We discussed the reasons why a suction cup may come off at the very beginning of the article; these sources of falling are the same for both home conditions and a car. Now we will analyze in detail the methods of reliable fastening.

Wetting. But many people wet the concave part of the suction cup with water, alcohol, or even saliva, which is not entirely correct. Moisturizing for greater grip is, of course, good, but in cold weather such liquid will freeze, and in hot weather it will simply evaporate. Therefore, you need a consistency that will not harden, freeze or evaporate. Motor oil is ideal for this purpose. Literally a drop of this oil needs to be applied to your finger, and then rubbed over the rubber of the suction cup and glued to the car window.
Additional lining. This technique is suitable for massive suction cups with a lever. Often this lever makes a thorough rotation before it begins to create a vacuum, and only begins to work at the end of the clamp. It turns out that the main part is working in vain. It is this moment that should be reduced and additional lining made. For laying, a regular car inner tube is suitable, in which you need to cut a circle with a radius equal to the suction cup. Then, in the resulting rubber mug, you should cut out the middle so that there remains, as it were, one rim, which will need to be inserted between the suction cup and the plastic recorder holder itself. For a more detailed and visual study, you can see the corresponding photo with an arrow pointing to the gasket. It would also be a good idea to lubricate this design with oil. When you start gluing the improved suction cup, you will immediately feel how much the pressure inside has increased.
For car windows with silk-screen printing, airbrushing or other “pimples”, many motorists come up with a lot of fun ways to hang the necessary devices. For example, some use an option with an anti-slip mat, which is attached to the spray coating with car painter's double-sided tape. And a gadget with a suction cup is already glued to the mat. The method with glass mugs or simple smooth glass from an old flashlight is also widely used. Again, this structure also needs to be glued. Gel-based “superglue” is in demand, with the help of which a piece of glass is attached to the embossed part of the windshield.

Self-adhesive or silicone - for the most hopeless cases or in winter. This is the very case when your devices refuse to “cooperate” with the options described above. In all methods, of course, it is necessary to follow the basic rules of application and application, which include good temperature conditions and a grease-free surface.

Taking our advice into account, you can quickly and easily attach an incredibly beautiful and stylish soap dish, outdoor thermometer or other convenient decorative elements with your own hands. And by applying some examples in practice, you will stop waiting for the moment when this suction cup shelf will fall!

What should I do to prevent it from falling off?

There are only two tasks:

How to properly wash a car engine with your own hands

Clear the atmosphere inside as much as possible.
Don't let that negative pressure escape

This is why the side edges of the suction cup are made so wide! And they try to make the material as elastic as possible so that it adheres well to the glass.

Many people wet the surface with water (or even saliva), this is of course correct, but in winter it can freeze, but in summer it simply evaporates. Therefore, you need a composition that will not evaporate, freeze or harden. Motor oil is ideal, you need a little on your finger, wipe the surface of the suction cup and attach it to the windshield. WILL HOLD ON for a very long time!

The second “jamb” of modern gadgets is the “lever” in the mount, which creates a lot of pressure. Often it makes almost a full turn (180 degrees), but it starts working only at the very pressure, only 25 - 35 degrees, that is, the remaining angle works idle. We need to reduce this idle speed, which is done - a circle is cut out of a regular car camera, along the rim of the suction cup (like a gasket), then all the insides are cut out inside and it is inserted between the suction cup and the body.

Once you start pressing the suction cup with the lever, this “spacer” will reduce the idle speed and increase the pressure inside. IT WILL HOLD SEVERAL TIMES BETTER, tested many times.

Here's a short summary:

Checking the rubber or silicone surface for damage
Degreasing glass
Lubricate the surface of the suction cup (motor oils are ideal because they do not freeze in winter and do not evaporate in summer)
You can make a spacer (ideally from a wheel tire) between the plastic and rubber (silicone) components, thus increasing the pressure

Now we are watching a short video version.

I end here, I think my article was useful to you, sincerely your AUTOBLOGGER.

Under what conditions is it difficult to install the holder?

The most common reason for weak fastening of the DVR bracket is low temperature, usually the suction cup falls off in the cold. This happens because rubber or silicone hardens at low temperatures and loses its elasticity. Also, the rubber band does not hold up in the heat; if you left the car for a while in the sun, you should not be surprised that upon your return you will find a fallen recorder.

It will be difficult to install the holder on glass covered with dust; the rubber circle itself should not be dirty either. The suction cup holds very poorly on uneven glass, for example, if it is silk-screened. Here it is no longer possible to level the surface; you need to figure out how to ensure tight contact. Another thing to consider is that there are a lot of Chinese products on the Russian market, and the fastener may initially be defective.

Surface quality and suction cup

First of all, you need to make sure that the product you buy with a suction cup will not be unsuitable for fastening. High-quality material must have an absolutely smooth inner surface. It is this factor that determines the choice. Be sure to run your fingers over it. If you feel a depression or bump, it is better to refuse such a product.

Please also note that the shape of the suction cup must be correct. Another important aspect is the assessment of the tile surface

It must be perfectly flat, since it will not be possible to glue the suction cup onto a textured tile. Smooth gloss is best suited for this purpose. Pores on the matte surface can weaken the bond. And raised protrusions, various surface defects, particles of glue or putty are not at all capable of holding a suction cup

Another important aspect is the assessment of the tile surface. It must be perfectly flat, since it will not be possible to glue the suction cup onto a textured tile. Smooth gloss is best suited for this purpose. Pores on the matte surface can weaken the bond. And raised protrusions, various surface defects, particles of glue or putty are not at all capable of holding the suction cup.

In order for the suction cup to adhere well to the tile, you need to make sure that the product is of high quality, and that the tile is even, and preferably glossy

It will not be possible to securely attach the suction cup to a chip or crack. Unfortunately, it will not be possible to disguise these flaws in this way. The only way out is to fix the object hanging down a few centimeters above this flaw.

What types of mounts are there for DVRs and their features?

When choosing a DVR for a car, one of the priority parameters, in addition to the quality of shooting and viewing angle, is the type and reliability of the mount. Typically, the device has to work in difficult conditions, for example, driving over potholes, bumps, gravel roads, etc. Therefore, it is very important that the mount holds the recorder well. In addition, many people now, fearing theft, do not leave the device visible on the windshield. Therefore, the mount must provide the ability to quickly remove and reinstall the DVR housing. This means that when purchasing, you must pay attention to the type and quality of fastening.

Main types of mounts for DVRs

In total, DVR manufacturers currently offer devices with three main types of mounts. Naturally, all options have their own advantages and disadvantages, which determine the features of their operation.

Sticker (3M tape)

This is the simplest option for mounting DVRs in the car. There is a strip of double-sided tape on the body; by removing the protective film, the driver can fix the device on the windshield.

pros

Easy to install the device. Everything is obvious here - no additional devices or manipulations are required, you can attach the recorder in a couple of seconds.
Reliability of fixation. This type of mount is considered very stable and strong and holds the recorder body well on the glass.
Possibility of installation in any convenient place.
Minimum sizes. This significantly simplifies the task of installing a video recorder if there is little space in the cabin.

Minuses

One-time use, the device cannot be removed and re-attached to the same tape.
Suitable only for small devices of light weight.
The adhesive base of the Velcro can leave marks and damage the glass.
