Face recognition access control common problems and solutions
Intelligent face algorithm plus sensitive card swiping and fingerprint sensing modules can verify and open the door in seconds. It is suitable for office buildings, factories, schools, and other access control places where the door can be opened without contact verification. But things can’t be 100% perfect. Have you ever encountered the problem that the face recognition access control will not open the door if the verification is valid, and the screen will freeze?
Face recognition access control system verification is effective and the door is not opened. Trouble analysis and solution:
Failure Analysis
a. The network signal line is not connected properly;
b. The power supply cannot supply power normally;
c. There is no unlock signal output during verification;
d. The matching electric control lock is faulty.
Solution
a. Need to reconnect the signal line and test again;
b. Short GND/PUSH test;
c. Connect the COM/NO detection signal;
d. It is recommended to replace the new electric rim lock detection.
There are two methods to solve the problem that the face recognition access control screen freezes and does not move:
1. Whether the camera driver of the access control device is operating normally, the solution is to uninstall the camera driver, and then restart the face access control to test whether it is operating normally.
2. If there is a fault due to the full memory, the solution is to clear the memory data of the access control device and clear the access control data regularly at a specified time.
The above is the analysis and explanation of how to solve the problem that the face recognition access control verification is effective and the door is not opened, and the screen freezes. I hope it can help everyone who needs face access control.
