  Intercom Video Monitoring

This quick guide describes how to setup monitoring of 2N IP intercom cameras on Yealink T58A/V.

IP addresses used

2N® IP Verso
Yealink T58A

Intercom setup

After you log in to the intercom, go to Services and then HTTP API. Locate the Camera API row and change Connection type to Unsecure (TCP) and Authentication to None.

If you’re getting poor framerate or would like to save some bandwidth, you can decrease JPEG quality in Streaming>JPEG down to 50.

Phone setup

Log in to the phone’s web interface and go to DSSKey tab. Choose one of the Line Keys, click on its Type dropdown menu and select Video Monitoring. The most important field here is Value, this is where you put the address of the intercom’s HTTP API camera stream in the following format:

http://intercom’s IP/api/camera/snapshot?width=640&height=480&fps=15

The remaining fields are Label and Extension. Label is the name which will identify the intercom’s camera on the display of the phone. Extension is not important in this scenario, but you can enter the intercom’s IP.

The following picture shows that I have assigned one intercom camera to the phone’s DSS Keys using its respective IP address.

How it works

DSS Keys are accessible on the right side of the phone’s home screen.


Once you tap on it, it immediately show your intercom’s camera feed.
