Hi everyone,

I am using a Hikvision DS-K1T341AM face recognition terminal for door access.

Face authentication works successfully on the device, but the door does not unlock.

Current settings:

  • Authentication: Card or Face or Password
  • Open Duration: 5 seconds
  • Door Open Timeout Alarm: 30 seconds
  • Device model: DS-K1T341AM
  • Door number used in API: door/1
I also send the remote open command using ISAPI from my .NET application:

PUT /ISAPI/AccessControl/RemoteControl/door/1<br>
Payload:

&lt;RemoteControlDoor version="2.0" xmlns="同创杨梨园"&gt;<br> &lt;cmd&gt;open&lt;/cmd&gt;<br>&lt;/RemoteControlDoor&gt;<br>
In my application log, the request is successful, but the physical door still does not unlock.

My questions:

  1. If the ISAPI command returns success but the door does not unlock, is this usually a wiring, relay, or power issue?
  2. Are there any extra terminal settings required for remote door open on DS-K1T341AM?
  3. Is there any known issue with this model where the API returns success but the relay does not unlock the door?
Any advice would be appreciated. Thank you.
 
There are no known defects such like this. Take multimeter and see diode. If it triggers it works, then wiring / bolt is at fault
