Everyone knows that the Vehicle mobile DVR is actually a segment of the traditional embedded DVR.

It is an emerging special product developed with the application of digital video and audio coding technology in vehicles. The car DVR combines digital video and audio codec, harsh environment, large-capacity data hard disk storage, automotive electronics, wireless video network transmission, GPS satellite positioning and other advanced technologies to achieve video and audio monitoring for passenger operation, special vehicle industry and other related fields. As a market segment of traditional embedded DVRs, in-vehicle DVRs have also welcomed many security companies.

Although the car DVR is said to be a new product of the era in the security industry, but regard its technology, I am afraid that only those who have actually manufactured mobile DVR can understand. Car DVRs should pay attention to the following aspects when purchasing according to different industry needs:

The anti-vibration performance of the car DVR. Vehicle DVR is applied to mobile vehicles. Due to different vehicle conditions and road conditions, the vibration is relatively large, which has a great impact on the hard disk read and write data, and the damage to the equipment is very large. Therefore, seismic technology has become the most basic requirement for vehicle DVRs. Although the embedded system is the same as the ordinary DVR, the car DVR technology is more complicated than the ordinary DVR, and the key to be solved is different.

Therefore, when purchasing a product, it is necessary to carefully observe whether the interface is secure. Some manufacturers put most of the interfaces on the rear panel together, replaced them with a multi-pin interface, and bundled all the data lines into one bundle, which played a very good role in the interface.

Car DVR wireless transmission. In addition to providing local video and forensic materials, the vehicle DVR also needs to send the obtained video information back to the control center in time to facilitate the control center to keep abreast of the situation and centralized management. Therefore, wireless transmission is particularly important. At present, the main use of 4G network.

Car DVR is waterproof.

Vehicles are generally cleaned every day, especially on buses. After the bus enters the station, the staff will use the water to wash the car. If you don’t pay attention, the water will spill on the equipment. If the waterproof performance is not good, the water droplets may enter the inside of the chassis. When the vehicle is started, it may be Burning equipment, therefore, the waterproof performance of the car DVR can not be ignored.

The dustproof capability of the car DVR. During the driving process of the bus, the passengers on the car go up and down, and dust is indispensable. Therefore, the product is also highly demanded in terms of dust prevention. When purchasing products, users should choose products that are completely enclosed and have good interface sealing. Prevent dust from entering the inside of the chassis to avoid affecting the stability of the product.

The car DVR is compact.

Car DVR products are pursuing the appearance of miniaturized design, which is not only the appearance of the product is beautiful, but also the main purpose is to meet the narrow installation environment inside the car. Since the models of large buses, small buses, and private cars are different, the interior space is also very different. Therefore, when purchasing products, it is necessary to select different sizes of vehicle DVRs according to the models.

The built-in DVR has a high degree of integration. The car DVR is not just a single product. It can’t just be connected to the camera for surveillance video. It should also have a rich interface and can be integrated in some large projects, so the space is even bigger. Therefore, you can check whether the interface is rich, whether it provides some protocols, whether it is convenient to upgrade, and whether it is compatible with the access platform.

Vehicle mobile DVR hard drive size. In general, the hard disk space should be large enough, otherwise there will be no space in less than a month. At the same time, there must be an interface to copy the data directly without disassembling the DVR. At the same time, to meet the needs of customers, the quality of the hard disk should be reliable, and it can’t be broken in less than a month.

Car DVR black box. The black box is also called “Motor Vehicle Recorder”, which is one of the important functions of the vehicle DVR. It can record all the data of the whole process of motor vehicle operation, and can realize the management and supervision of the driver through the CMSV6 computer software. When the vehicle is overspeeding or there are other violations, the black box will transmit the information to the control center for early warning.
