Howto:Working with multiple Door Cameras

Applies To

This information applies to

• V10 and innovaphone PBX platform
• innovaphone phones supporting video
• web server running PHP 5

some innovaphone phones support display of a door phone camera picture (see Howto:Door Phone with Video in V10 and later). However, only one camera is supported. This article describes a solution for use of multiple door cameras.

More Information

Overview

When multiple door cameras are used, the standard mechanism described in Howto:Door Phone with Video in V10 and later is not sufficiant, as the URL used in the phone is static and will always show the same door camera. Instead, the image should switch from one camera to the next continuously. Also, when the operator is called by the door phone, the picture from the calling door should be shown always. This can be achiedved using a this SOAP-based urtiliy.

Prerequisites

This SOAP script requires a web server running PHP5. A Linux Application Platform is fine, but any other PHP platform should do too.

Configuration

doors.xml

The utility comes with a working sample configuration (in doors.xml). This file must reside in the same directory you installed the PHP script (DoorControl.php) too. The sample file looks like this: <?xml version="1.0" encoding="UTF-8"?> <doors

   pbx="145.253.157.200"
   pbxhttp="demo"
   pbxpw="demo"
   pbxuser="_TAPI_"
   interval="5"

>

   <door 
       url="http://baudisch.dyndns.org/jpg/image.jpg" 
       name="ckl-1"/>
   <door 
       url="http://216.123.238.208/axis-cgi/jpg/image.cgi" 
       name="door2"/>
   <door
       url="http://rax1.bsn.net/axis-cgi/jpg/image.cgi"
       name="door3"/>

</doors>

doors

The root tag doors has a few attributes which define the PBX access (used to determine if a phone is being called by a door phone):

pbx

the IP address of the PBX

pbxhttp

the HTTP user to be used to access the SOAP service on the PBX (usually the Name' of a PBX user object or the admin user)

pbxpw

the password of the HTTP user

pbxuser

the Long Name of a user object that is used to access the SOAP service on the PBX

Also, the interval between switching the available door cams must be defined

interval

the number of seconds the utility will wait before switchign to the next camera

door

Each sub-tag door defines an available door camera.

url

the URL to retrieve a single picture from this camera

name

the Name of the PBX user object the door phone is registered with. You must use the single-picture URL here (usually ending in .jpg), not the picture stream (.mjpg). Otherwise, the phone will never switch to the next camera.

Phone

The Background Image property in Phone/Preferences must be set to the DoorControl.php script on your web server. It supports 2 arguments

id

e.g. id=operator, the Name of the PBX user object the calling phone is registered with. The script will use this name to query the PBX if the phone is currently being called by a door phone.

debug

if this is set, the script will not deliver the requested picture but will spit out some debug information
