3 Analysis of customized functions in the financial industry
Banknote transport vehicles in the financial industry require the on-board hard disk recorder to work stably and reliably, and can upload video and alarm information to the management center platform in real time when an emergency occurs, and can interact with the monitoring center platform.
4 Automobile electronic customization function
The on-vehicle hard disk recorder should also be combined with related functions of automotive electronics, for example: car driving data collection and upload generally use CAN bus technology, and the on-vehicle hard disk recorder should also have CAN bus access and analysis processing functions to record vehicle driving related information through the hard disk , And analyze and process important data.
5 Other vehicle-mounted DVR applications
Rail transit, shipping, aviation and other industries also have real-time monitoring needs. In addition to adding hard disk shock absorption and reinforcement treatment, these industries also need to pay attention to the difference between the power supply used in such projects and the power supply of ordinary cars. For example: trains provide on-board equipment. The power supply is mostly DC48V or DC110V, while the ordinary vehicle power supply is DC12V or DC24V
