b: Whether the key switch of the host is locked
c: Whether the ignition control line of the host is connected properly,
d: whether there is a control voltage input (when testing in the office, the ignition control line is directly connected to the positive pole of the host power input)
2：The hard disk video recorder automatically restarts after a few minutes of startup or often crashes？
a: Input voltage is unstable or too low
b: The hard disk wiring is loose or poorly connected
c: Hard disk has bad sectors
d: Poor heat dissipation, too much dust, and the machine operating environment is too harsh
e: Inadequate installation of anti-vibration facilities
3:The remote control does not work?
a: Check the power section on the remote control
b: If the hard disk is installed, check whether the hard disk is inserted in place
