5.3.4 Camera

This menu is only available in the 2N IP intercom models that are equipped with an internal camera or can be connected to an external camera. The camera signal can be streamed directly into the call via a videophone, sent by E-mail, streamed via ONVIF/RTSP to another device (a video surveillance device, e.g.), or simply HTTP downloaded from the intercom in the JPEG format.

The following video signal sources can be used:

  • an internal integrated camera or external analogue camera (2N® IP Video Kit only)
  • a standard external IP camera supporting RTSP stream with codecs MJPEG (640 x 480 max resolution) or H.264 (640 x 480 Base Line Profile max resolution). The recommended framerate is 15 frames per second in either case. Higher frame rates may result in undesired effects (less smooth playing).

The Camera menu helps you set such camera parameters as brightness, colour saturation and external IP camera login data if necessary. Refer to the Services / Phone, Services / Streaming and Services / E-Mail menus for the video call/streaming parameters.

List of Parameters

Common Settings

  • Default Video Source – set the default video signal source. Choose Internal camera (or an analogue camera connected to the intercom) or  External IP camera. The change of the default video signal source is applied to the RTSP stream and HTTP API. In 2N® IP Eye it is required to enable the external camera manually, even when there is no internal camera present in the device. If no internal camera is connected to the intercom, External IP camera can only be selected. If the external camera is not connected or configured properly, N/A is displayed on a blue background.
  • PTZ Control Enabled – enable the PTZ (Pan-Tilt-Zoom) function to control the camera display area during the call via DTMF (Enhanced Video license required) from your IP phone numeric keypad. Click the * key to enable/disable the PTZ mode. The meanings of the IP phone keys in the PTZ mode are as follows:
IP phone key
PTZ mode function
* Enable/disable PTZ
1 Zoom in
3 Zoom out
2 Move zoom region up
4 Move zoom region to the left
6 Move zoom region to the right
8 Move zoom region down
5 Return to initial state
  • Live Preview – display a live preview from a 2N IP intercom camera.

Internal Camera

  • Brightness Level – set the camera image brightness level.
  • Color Saturation – set the camera image colour saturation.
  • Camera Mode – select suitable camera modes according to the current intercom installation conditions (indoor/outdoor use). Choose variable image flicker cancellation modes for indoor sites illuminated by artificial light. Or, set direct sunshine suppression for outdoor applications.
  • Automatic Framerate Decreasing – enable automatic frame rate decreasing under worsened illumination conditions to improve image quality by lowering the frame rate.
  • Image Trimming – the 2N® IP Force camera view angle allows you to scan the largest area possible. Use this parameter to enable automatic camera image trimming to eliminate the (sometimes annoying) view of the intercom frame. Disable this function to get the maximum possible view angle. The parameter is available in the 2N® IP Force models only.
  • Day/Night Mode  set the camera day/night mode. The options are automatic (controlled by the ambient light level), or permanently day or night mode. 
  • Current Mode  display the currently selected camera mode (day/night). in the day mode, the camera uses an IR suppressing filter and  infrared  illumination is disabled. In the night mode, the IR suppressing filter is disabled and infrared illumination is on.
  • IR LED Brightness Level  set the infrared LED brightness level in the range of 0-100% in several steps. Infrared illumination is automatically activated in night mode. The IR LED brightness level settings are only available in the 2N® IP Verso and 2N® IP Verso with HD camera models. 
  • Current IR LED Brightness Level – display the current IR LED brightness level percentage. The level can automatically be decreased below the set value so that the maximum power consumption cannot be exceeded (typically, when multiple extenders are connected and PoE supply is used).
  • Live Preview – display a live preview from a 2N IP intercom camera.


  • This setting is only available in the models equipped with an external analogue camera input.
  • Video Input – choose one of the analogue camera inputs. You can change the input by automation via the Action.SetCameraInput during operation.
  • Video Standard – set the video standard for the camera connected. Modify the value only if the automatic video standard detection does not work well (Auto value).


  • Motion Detection Enabled  enable automatic motion detection via an internal camera. Motion is detected by monitoring of a brightness change in the selected image section in time. When objects move within the camera range, the selected part of the image detects an activity, which can be expressed in percentage. If the activity exceeds the upper limit, motion is detected and indicated as long as the activity drops below the lower limit. Select the sensitivity thresholds and detection area according to the requirements and installation site conditions.

  • Sensitivity Threshold set the lower and upper sensitivity and hysteresis limits for the motion detecting algorithm. 
  • Detection Area  set the rectangular detection area in the image.
  • Activity Graph  display the activity history (image brightness changes) including the upper/lower sensitivity thresholds.

External Camera

  • External Camera Enabled – enable RTSP stream download from the external IP camera. Complete the valid RTSP stream address or the username and password to make the function work properly.
  • RTSP Stream Address – enter the IP camera RTSP stream address: rtsp://camera_ip_address/parameters. The parameters are specific for the selected IP camera model. If you choose another 2N IP intercom for the external camera, enter http://ip_address/mjpeg_stream or http://ip_address/h264_stream.
  • Username – enter the username for the external IP camera authentication. The parameter is obligatory only if the external IP camera requires authentication.
  • Password – enter the external IP camera authentication password. The parameter is obligatory only if the external IP camera requires authentication.
  • Local RTP Port – set the local UTP port for RTP stream receiving.

The Camera Preview window displays the current image received from an external camera. If the external camera is disconnected or configured incorrectly, the N/A characters are displayed on a blue background.
The External IP Camera Log displays the RTSP communication with the selected external IP camera including failures and error states if any.
