The electric elevator door in the community can be lifted remotely, but the scanned license plate cannot be lowered directly. What happened?

System failure, system setup error, communication problem.

1. The license plate recognition system is out of order, the license plate cannot be recognized, and the descent of the elevator door cannot be controlled. You can contact the property of the community or the manufacturer of the elevator door for maintenance and inspection.

2. The license plate recognition system is set incorrectly, and the license plate cannot be correctly recognized, so it is impossible to control the descent of the elevator door. You can check whether the license plate recognition system is set correctly, or contact a professional for setting and debugging.

3. There is a communication problem between the license plate recognition system and the elevator door control system, which makes it impossible to control the elevator door descending correctly. You can check whether the communication line is normal or contact professionals for maintenance and debugging.
