Contents
Introduction
All the commands required to use the video display intercom will be described in this document. The following IP addresses will be used throughout the document:
- Video Display on Master Station IP address = 192.168.1.24
- Master Station IP address = 192.168.1.23
- AlphaCom IP address = 192.168.1.5
- Video Camera on Substation IP address = 192.168.1.12
The video display does not support an Ethernet cable from a PoE port. Power for the video display can only be obtained from an external power supply (available from Zenitel).
Technical personnel responsible for video display programming should have some working experience with STENTOFON software/interface such as AlphaPro and AlphaWeb.
Hardware Architecture
The intercom system architecture including video display is based on the following equipment:
- AlphaCom server (XE1/XE20/XE26)
- IP Master Station with video display (item no. 1038001535/1038000535)
- IP Video Substation with video camera (item no. 1038051415)
- IP Video Door Station with camera (item no. 1401110100)
A simplified diagram of the system configuration is shown to the right:
Functional Architecture
When someone initiates a call from the substation with video camera, the AlphaCom server sends a request to the AXIS camera which broadcasts its video stream on the LAN/VLAN. The command is generated from two scripts programmed in AlphaCom (one script for video stream connection to the video display and one script to disable the video stream from the video display).
This video stream is recovered by the AlphaCom server which transcodes the stream to a 320 x 240 pixel format so that it can be displayed on the video display.
Prerequisites
Video Stream
The video stream is read from the video display on a web server specified by the AlphaCom server. Hence, there is no recommended size or duration for the source file. The image resolution must be 320x240 pixels. Other resolutions are not supported.
Recommendations:
- File extension: mpg
- Resolution : 320x240 pixels
- Video Codec: MPEG-2 at 800 kbps
Powering Up the Video Display
The circuit board must be powered with an external 12 VDC, 1A power supply. No protection is provided on the board.
NOTE: Do not use a PoE switch port as a power source.
Video Display Settings
To set up the video display, the user must connect an Ethernet network cable to the master station. The user interface is accessible via a Telnet connection. The setup procedure is as described in the following sections.

To change the net mask on the video display, change the value of the variable netmask e.g.:
- fw_setenv netmask 255.255.255.0
Test Camera Video Stream
To ensure that the video display is able to receive a video stream from the network, the following command has to be run:
- mplayer -demuxer lavf
The following is an example command to receive the stream from a video camera with IP address: 192.168.1.12:
- mplayer -demuxer lavf http://192.168.1.12/mjpg/video.mjpg
The video stream should now be displayed on the video display on the master station.
The above window appears when you get a good reading from the stream of the video camera.
To stop the streaming, press CTRL + C.
Modify Standby Logo on Video Display
Prerequisites
Save the image/logo to be displayed under Scripts in AlphaWeb.
The new image/logo will be displayed when there is communication between the video display and the AlphaCom server. Otherwise, the default STENTOFON logo is displayed.
The image/logo must have the following features:
- Image resolution: 380x240 pixels
- Format: jpg
Image/Logo Update
The image can be updated by using the variable imgurl available on the master station. This variable contains the address of the server where the image is saved (in this case, it is the IP address of the AlphaCom server).
To insert a new image:
- Log into AlphaCom via AlphaWeb
- Select the Custom Scripts tab and log in to your PC with the following access code:
- - User name: scripter
- - Password: alphascript
- Click Browse and navigate to the folder where the image CE.jpg is located
- Click Upload
If you wish to confirm the image change, run the following command:
- fw_setenv imgurl http://192.168.1.5/cmd/CE.jpg
192.168.1.5 is the address of the AlphaCom server that contains the registered logo/image CE.jpg.
The image modification will take effect after the video display is rebooted, when the new logo has been downloaded.
To reboot, run the following command:
- reboot
The video display will then restart and the new logo will appear.
