[Asterisk-video] IP Camera to Asterisk Interface

Thu Feb 22 09:36:10 MST 2007

The transcoding is not difficult to implement, but is very cpu intensive.
With a camera that supports h264 and
rtsp, a simple integration would be quite easy..

Thanks sergio...

another had suggested a solution to the mpeg/jpeg codec problem might be to
somehow chain in ffmpeg to convert the stream...  Sounds a lot more
difficult,  but I managerd to find these cameras that support the H.264
codec:

Many cameras suppor video playing with rtsp
http://www.axis.com/techsup/cam_servers/dev/cam_rtsp_api.htm
so it wouldn't be too hard to implement an application for asterisk that
implement some simple rtsp player, connect
to the camera and receive the rtp packets, forwarding them to the asterisk
channel.
The problem is that mos cameras support only mpeg-2 and mpeg-4 and I don't
know many videophones that support
them...

Greetings
    Sergio

I think the largest challenge is converting the JPEG/MPEG stream from the
camera into an H.263 or H.264 format...  and wouldn't the camera need a SIP
stack in order to negotiate the connection?    Of course CallManager is my
platform of choice seeing as Im a cisco partner...  but I figured something
like this would lend itslef more to and adaption to asterisk,  and then
setup a trunk between asterisk and callmanager to allow the 7985 video
phoens and other SCCP compliant video conferencing endpoiunts to "Dial" a
camera connection....

Really what I'd like to do is get the manufacturer to build a sip client
directly into the firmware of the camera and just register it like a
phone...  but I think my chances are better,  and I wouldnt be locked to a
particular vendor,  if middleware could be written to proxy register the
cameras...

Hi,

More intuitive will be to have the IP info on sip peer for the video feed.

Cisco Call Manager has something like...

Best regards,

Brandon,

Would you necessarily need to dial up the camera?

What about 'dialing' a web page that had the video feed rather than a camera
ip address?

Has anyone heard of a means to interface an IP video camera.. for example
Axis or Sony, using some type of middleware so that you could dial an
extension from a video phone and pull up one way video from the camera to
the video phone?     Even better would be to start with software like
Zoneminder and add an extension to register views within the recording
program which could be registered with Asterisk and demand dialed form a
video phone?    Any help or direction would be greatly appreciated...
