1, sd truck video recorder
Adopting the latest international cutting-edge technology, the new generation of high-definition products with D1 resolution as the mainstream; compared with the traditional old products with the same resolution of the CIF counterparts, the SD card camera in the car at the same code rate (ie, the same video file size) Can provide 2 to 4 times higher image quality and clarity, is the ideal choice for a new generation of car video recorders.
With the continuous expansion of the capacity of the SD card, the current 64GSD card can basically satisfy the recording time requirements of most customers, and can support the 64G SD card currently on the market. Some products support the simultaneous storage of two SD cards. The storage capacity is doubled. With the continuous development of SDXC technology and continuous reduction in costs, 64GSD cards have gradually become the mainstream. If dual-card hosts are used, the storage capacity is 128G, and the recording time is even longer. Long 2 hard disk car video recorder
Car DVR is a segment of the traditional embedded hard disk recorder. It is an emerging special product developed with the application of digital video and audio coding technology in vehicles. Car DVR integrates advanced technologies such as digital video and audio codec, hard environment large-capacity data hard disk storage, automotive electronics, wireless video network transmission, GPS satellite positioning, and realizes video and audio monitoring in the passenger transportation industry, special vehicle industry and other related fields. The specific implementation of vehicle-mounted monitoring systems mainly includes cameras, pickups (microphones), onboard four-way digital video recorders and other equipment.
If the above summarizes the hardware aspects, the following is the difference between the use of software
3, GPS vehicle video recorder
GPS is the abbreviation of GlobalPositioningSystem (Global Positioning System) in English. Using GPS positioning satellites, a system for positioning and navigation in real time on a global scale is called a global satellite positioning system, or GPS for short. The current GPS car video recorder is mainly based on positioning, recording the trajectory, there is an essential difference for the navigation, popular point, navigation is based on user input starting point, termination point, and then analyze and optimize a line, guide the line, positioning It's just what precise position you are in now. The current use of vehicle transportation management is very extensive.
4, 2G car video recorder
Most of the mobile phone networks we use today are 2G networks, and 2G networks such as Mobile Unicom's SIM cards are used. The use of car video recorders mainly involves the embedding of a chip with a SIM card carrier on the circuit board. Voice, video, image communication, etc.
5, 3G car video recorder
3G has so far been the most prosperous in the field of vehicle-mounted monitoring. It refers to cellular mobile communications technology that supports high-speed data transmission. 3G services can transmit voice and data information at the same time, generally at a rate of several hundred kbps or more. 3G refers to a new generation of mobile communication systems that integrates wireless communications with multimedia communications such as the Internet. Currently, 3G has four standards: CDMA2000, WCDMA, TD-SCDMA, and WiMAX. The main difference between 3G and 2G is the improvement in the speed of voice and data transmission. It can better achieve wireless roaming around the world and handle various media formats such as images, music, and video streaming. The 3G car video recorder is currently using front-end data stream acquisition, fed back to the host server through the 3G network, and then shows the real-time front-end situation through the platform.
What types of car video recorders are divided into
Car video recorders are currently divided into five types according to hardware standards and software applications: hardware sd card type and hard disk type car video recorders, according to the use of software functions: gps2G3G car video recorder. First introduce the following separately:
