This FAQ may be applied to 2N IP intercoms where no Enhanced Video License is installed. Firmware tested: 2.23. IP Address of the tested intercom was 192.168.50.133
For cases like these, there's a workaround to view camera feed or integrate into NVR or VMS systems using HTTP API. This will not provide access to any of the advanced functions of ONVIF or RTSP, but it offers the possibility to view the intercom's camera feed. There are two ways to access the camera feed:
You can access it freely without any sort of authentication. To do that, simply change these two values to Unsecure (TCP) and None.
If you'd like to access the camera feed securely, which is always recommended, keep it at its default settings: Secure (TLS) and Digest. Then pick an account, enable it, and enter User Name and Password combination according to your preferences, then in User Privileges, enable Camera monitoring.
Enter the following string into any of the following programs and replace IP_address with your intercom's respective IP address. You can adjust the following image parameters to save on bandwidth: Width and Height define image resolution in pixels, 1280×960 px is maximum. FPS defines how many frames per second the stream will have, maximum is 15.
If you're getting poor framerate or would like to save on bandwidth while keeping high resolution and framerate, you can change the default JPEG compression quality down to 50 here.
The easiest way to view the camera feed would be from your web browser. Just enter the above string into your web browser's search field. Depending on whether you chose to secure your intercom's camera feed or not you'll be asked to enter the HTTP API Account credentials you filled in previously.
Shortly after, the camera feed appears in your web browser.
VLC media player can open various media formats, one of which are network streams. To access this functionality, go to Media>Open Network Stream.
The following window opens, enter the above mentioned string and adjust parameters if necessary.
Again, depending on whether you chose to secure your intercom's camera feed or not you'll be asked to enter the HTTP API Account credentials you filled in previously.
After clicking on Ok, the camera feed appears.
The same string would get you image in any NVR or VMS system that supports it.
