- Support import/export operation log, a variety of event logs, configuration files, system parameters.
- Upgrade support TF card, USB, eSATA, 3G network, Wi-Fi, Gigabit Ethernet.
- Rich expansion interface, CAN bus, RS232 and RS485 two each, supports clearance channel transmission, support PELCO-D control protocol.
- Rich alarm input/output ports, support 16 channel alarm input, 5 channel alarm output, could collect turn left, turn right, braking, reversing and other information.
- Use onboard dedicated air plugs, ensure that the signal connection is stable.
- Built-in secondary power management, with the ACC ON, delay shutdown and 24 hours timer switch; low power standby (over 30 days).
- DC8-36V wide voltage input, suitable for DC12V and DC24V vehicles; anti-pulse voltage, under-voltage protection features to meet the requirements of automotive electrical characteristics.
