Vehicle-mounted digital video recording hardware adopts efficient H.265 compression to support analog cameras and AHD cameras ranging from 2MP to 8MP for multi-channel synchronous capture. Dual SD card slots are equipped to accommodate storage media up to 512GB each, delivering stable loop recording and locked emergency footage upon collision impacts. Separate CVBS and HDMI output ports are reserved for local real-time monitoring and high-definition playback, offering clear video evidence for accident identification and fleet supervision. Shock-resistant internal layout adapts to bumpy driving conditions of trucks, buses and engineering vehicles, with wide voltage input for steady operation under complex vehicle power supply. All hardware supports flexible wiring installation and matches various onboard visual cameras, satisfying long-term monitoring demands for logistics fleets, passenger transport and commercial vehicles across global markets.
