The device cannot be shut down while ignition is in OFF status.
Check if the ACC signal wiring is correct and if there is the voltage from ACC wire after the key is turned off.
Check the ACC delay off time of parameter setting, the MDVR supports ignition off still working for 1-1440min, check this time setting.
If you have set timed recording, and the device is still in task recording, it will not shut down.
FOV of camera?
For 1/3’’ CMOS chip-set, f=2.1mm, 140 degree. F=2.8mm, 120 degree. f=3.6mm, 90 degree. F=4mm, 75 degree.
How to integrate with other systems via our device?
We provide two ways to integrate with our MDVR: one is SDK, another one is H-protocol.
The difference between 2.4G WIFI and 5G WIFI.
Our devices support 2.4G and 5G WIFI for selection.
For 2.4G, the speed is low, coverage area is far.
For 5G, the speed is fast, but coverage area is very close.
There is no silkscreen beside the SIM card slot. Which direction to insert the card?
SIM card direction: Face the front panel of device, let the SIM card chip-side down, then insert it with the missing angle on the left.
