Hikvision DS-K1T341AM: ISAPI open command succeeds but door does not unlock

[Veasna]

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.
