External camera is a feature enabling you to add any IP camera to the 2N® IP Intercom. Thanks to this feature you can see second video stream from 2N® IP Intercom. External camera can be placed for example behind the front door as well as somewhere outside the building. This is very useful because you can check if the calling person is there alone, if he/she already enters the building, if there is a thief next to him/her, etc. During the configuration of 2N® IP Intercom you specify which picture will be the first one that you see when somebody calls from the intercom – would it be a picture from internal camera or from external camera? After reading this FAQ you will find out how to set it and how you can easily switch between these RTSP streams.
From technical point of view 2N® IP Intercom allows you to download RTSP stream from a standard external IP video camera that supports 640x480 resolution RTSP streaming in the MJPEG format or the same resolution in the H264 codec, more specification you can find in the configuration manual. 2N® IP Intercom is processing stream from external camera by itself, so it means that nothing has been changed if you calling from intercom to some other device instead the video picture. It will the same SIP video call with the same codecs no matter what camera input are you using.
- 2N® IP Intercom with firmware 2.5.0 or higher, but it is strongly recommended always to use latest firmware. This FAQ page was done with 2N® IP Verso, using latest firmware 2.14.2 and as an external camera was used 2N® IP Vario (also 2.14.2)
- Before configuration please check if your device is capable of this feature in this manual section: Model Differences and Function Licensing.
- Enhanced Video license, if you to switch between internal and external camera during call you will need also Enhanced integration license, because of Automation feature.
