9. Frequently Asked Question
9.1: Found problems that can not be resolved?
A: Take note of the product model and software version, make detail description of the issues and submit to
the technical and engineers team for analysis. The more detailed you offered, the more convenient for our staff
analysis.
9.2: There is no video output?
1. Check the indicator lamps in the DVR. If the red PWR light is off, no power; If PWR is on
and RUN off, then check ignition cable. If ignition cable connected, may be the MCU inside
the DVR is broken; If RUN light is flashing(2s for once), the device is standby and not
startup yet; Check the red and yellow cable in power connection and make both of the cables
connected with power.
