What parameters should I look for when buying a dash cam? How to install a dash cam on a car?

A dashcam can be understood as a car surveillance camera, which is usually installed in the middle of the rearview mirror. A dashcam can record the driver's driving situation, which can be used as evidence to prove oneself at a critical moment. So how do you view a dashcam when you buy one? How do you install it?

What parameters should I look for when buying a dashcam?

Just grasp the following 5 parameters and it will basically be OK.

Wide angle.

Because theoretically, a recorder with a wider wide-angle angle can capture more scenes. However, a large wide-angle angle alone can also cause image distortion, so it cannot be said that the larger the wide-angle angle, the better. Generally, 140 degrees is sufficient.

Resolution.

The video data in the recorder is prepared as evidence in the future. 1080P is the basic requirement for image quality, and 1200 is also required. There is no need to go higher because the generated records will also be very large.

The quality and size of the SD card.

When the SD card is full, it will usually be overwritten in a loop, so it is better to have a larger memory.

Night shooting.

The effect of the recorders is not obviously different during the day, but at night when accidents are more frequent, it is time to test the recorders. There should be no mosaics, and the strong light must be weakened. A good lens has strong photosensitivity adjustment capabilities, and the recorded images will not be too bright or too dark.

brand.

Choosing a well-known and reliable brand can save you the trouble of identification, and these old brands will integrate a lot of high-tech, such as navigation, mobile detection, 24h parking monitoring and other practical configurations, which are worth the money.

How to install a driving recorder on a car

1. Suction cup installation

The method of mounting dashcams also varies by model, with many products using suction cups. Suction cup mounts adhere firmly to glass surfaces (windshields by default) and will not leave much of a mark when removed. Sticker mounts stick easily to windshields and other surfaces, but it is strongly recommended that you wipe the glass thoroughly and allow it to dry completely before mounting.

In addition, if you remove it, it will leave traces. The solution is to stick a layer of transparent traceless adhesive paper before installing such products. The properties of the adhesive are similar to those of the tape used to fix household appliances, and it can be torn off without leaving any traces.

Regardless of the attachment method, what is more important is the mobility of the dashcam when mounted on the mount. Most mounts have a swivel ball joint, which can sometimes be rough and difficult to move.

Some dashcams have two joints on the base, so this provides a better and easier method of positioning. Some are shaped like a cylinder, like their own positioning joints. These are certainly things to consider carefully when evaluating a lens.

2. Strap installation

For most dashcams that are four inches or larger, due to space and convenience considerations, they can be tied to the car's rearview mirror using two small rubber bands. Installation and untying are quite convenient, and this is the installation method chosen by most car owners.

3. Installation of central control base

This installation method is also an innovation for dashcams. It is a base fixed between the bottom of the windshield and the dashboard, and is often glued to the bottom of the windshield in front of the dashboard using 3M glue.

The advantage is that you don't have to worry about it falling off, and you don't have to keep looking up, and it is much higher than the dashboard, which is just the right angle for us to look at eye level, so it will be very comfortable and easy to operate.

4. Special installation for special vehicles

This is the most sophisticated installation method. The position of the strap-type installation mentioned above is good, and the position of the rearview mirror of almost all cars is almost the same when they leave the factory. This special car-specific installation bracket completely replaces the factory rearview mirror. Of course, the performance of the driving recorder will become high-end and classy with this installation method, and all kinds of the latest technologies will be installed. Simply put - it is standard on luxury cars.

How big a memory card does a dash cam need?

It mainly depends on the pixel of the dashcam. In the past, 16G was enough for the old model. However, with the continuous improvement of pixel, many dashcams have been upgraded to 4K images, so the required memory is getting higher and higher. The current basic requirement is 32G. In addition, most dashcams can record in a loop. The new one will overwrite the old one, so there will be no situation where the memory is full and the recording stops.
