Over the past decade, car DVRs have become commonplace from an expensive toy. The transformation of the device itself has gone from a separate module on the dashboard or windshield to a smart mirror-on-board computer in an ultra-thin (8 mm) case. The overview of the device presents: device, principle of operation, characteristics, advantages of the product.
Mirror on-board computer: what is it
The amount of standard electronic equipment in modern cars has ceased to amaze. One of the devices is a DVR that looks like an ordinary salon mirror when turned off.
Mirror - on-board computer
The mirror-board computer is a multifunctional device. It combines several useful gadgets: rear and front view cameras, a GPS navigator and a mirror itself.
By becoming the owner of multifunctional equipment, you can:
- filming;
- receive assistance in navigation;
- receive warnings about speeding;
- detect police radars on the road;
- park safely.
Technical characteristics in different modifications of DVR mirrors differ:
- Display size (in inches): 5.0, 5.5, 7.0, 9.66, 10.0, 11.88.
- Video (pixel): 1920x1080, 1280x720.
- Touch screen resolution (pixels): 1280x480, 960x480, 1280x320.
- Viewing angle (in degrees): 136, 140, 150, 160, 170.
The cameras record video at 30 frames per second.
An excellent example of a mirror-on-board computer was the Japanese device Fugicar, popular with Russians.
How it works
The design of the electronic device is sharpened to fix the situation on the road.
The main components of the device:
- Lens. The viewing angle of the optics is such that it covers the picture not only in front of the car, but also the surrounding infrastructure: houses, traffic lights, road signs.
- Matrix. In the models of the latest registrars, recording is carried out in Full HD resolution, which allows you to see the smallest details on the screen, for example, nameplates and license plates of cars in front.
- Microphone. This component is needed for the sound accompaniment of video filming.
- Recording device. The device writes constantly, but the memory capacity of the mirror-board computer does not allow storing a lot of information. Therefore, the recording is carried out cyclically: new videos are placed on top of outdated ones. However, it is not difficult to restore the chronology of the traffic situation, since each video has a name in the form of the date and time of shooting.
- Carrier. The miniature dimensions of the BC on the mirror make it possible to equip the device only with a compact Micro SD media.
The electronic device is powered from the onboard battery through the wiring or from the built-in battery (in some models it is replaced by a capacitor).
Principle of operation
While the car's engine is off, the on-board driver does not perform its function: it stops working and does not write. When the motor is turned on, power is supplied to the device and video recording starts immediately.
Types
The variety of car mirrors plunges drivers into confusion, so it’s worth understanding the types of equipment.
According to the design and functionality, mirror-recorders can be of two types:
- Single chamber (single channel). Limited in function, without sensors, devices record only what is happening in front of the car.
- Two-chamber (two-channel). The front camera records the traffic situation, the rear one helps in parking the car.
On-board aircraft can be equipped with a radar detector that detects police radio signals, as well as have a GPS module and a G-sensor (built-in gyroscope). Radar detectors are sometimes confused with jamming radar detectors.
How to install a mirror-computer in a car
Upon receipt of the goods, check the integrity of the packaging and the number of items according to the attached list. The box contains adjustable elastic holders that help to install the BC on a regular mirror.
On-board computer mount
A special cable is provided for connection to the OBD2 port. The length of the cord (1,45 m) is enough to lay the wiring under the interior trim. The GPS receiver can be installed in a convenient place in the car.
Advantages of a mirror-on-board computer
On-board computers on the mirrors, registering the traffic situation, act as impartial witnesses in an accident and other oddities on the road.
But devices have a number of other advantages:
- Do not attract the attention of intruders.
- Easily mounted and configured.
- Do not take up useful space.
- Expand the field of view for safe movement of the car.
- Maintain stable and high quality footage.
- Support 3G-connection, GPS and WiFi.
- Do not blind the driver at night with the headlights of the vehicle coming from behind.
- They have a variety of functions, including entertainment (video, audio, games).
How to choose a device
When choosing a car mirror, pay attention to the following parameters:
- Shooting resolution: Full HD quality provides excellent display and detail of the objects surrounding the car.
- Frame Rate: 30fps is smooth, while 25fps is not sharp.
- Viewing angle: 120° - the best option, in which the mirror does not need to be rotated. A value greater than 160° results in a blurry image at the edges of the picture.
- Screen diagonal: if the display is less than 5 inches, you need to transfer video files to a PC to view. Therefore, choose a screen of 5 inches or more.
Next, look at the functionality: radar detector, navigator, etc.
