Access and control PTZ webcam controls on ip cam with WebRTC?

[Hugh Reynolds]

Hi! I'm wondering if it is possible to use WebRTC to access the physical ptz controls on an ip cam from a webpage. Currently we have a small web app that we embed on a web page that allows a single user to control the position of the streaming cam through presets for about a 60 seconds. Any new/  additional users are put into a que and gain control once the 60 seconds for the previous user is up.  It's a little clunky and difficult to put into a responsive framework. We are looking to update this to something a little more streamlined, and mobile friendly. Any info would be appreciated. Thanks! -Hugh

Do you mean something like in this demo?

Very close yes! Only with programmable presets. Thanks!

Oh just realized you posted that vid! Nice.. I'm entirely new to WebRTC any direction you could point me in as to how this was implemented?

We did the same sort of thing about a year ago with a PTZ security camera.

The basic idea is that you have one client  whose job it is to control the camera and convert the streaming video into a webrtc media stream (the messier part).

For simply controlling the camera, the client took data channel messages and converted them to rest api calls that the security camera understood.

The latency of the rest api made interactive control not so great, but for going to preset positions, that wouldn't be an issue.

Hello, I know that the topic is a bit archival, but I try to find a sensible solution to control an external camera on my website. At the end of last year, I was able to do something like this - while the delay between button click and camera movement was about 10-15 seconds - so it was meaningless. Now I read on the WOWZA forum - that the best way to get rid of delays is Webrtc - but I completely do not know this technology. I want to put the streaming from the camera on the website where it will be possible to control and no codecs in activex and other browsers will be needed. Would you be able to tell me something, or help me?

In asking this question, you need to also specify what your programming skills are and what type of api you have to access the camera's ptz.
