Stardot 5MP Webcam performance?

Post by tcarmen »

After following a bunch of dead ends, I finally got Zoneminder working with a StarDot NetCam SC 5MP camera, however the performance seems to be poor, and I'm looking for a sanity check and hopefully some help.

I'm getting 3 fps @ 1600x1200 px, but the camera is advertised as being able to handle at least 10 frames/sec even at the maximum resolution of 2592x1944.

Thinking it might be a network problem I even tried connecting the ZM box and the camera on a dedicated switch, however it didn't make any difference.

Right now, I'm using the mjpeg.cgi interface, however the camera also has am interface labeled "video streaming" on port 8001. The help file says:
"To view the motion JPEG stream without going through the web port, you can use a dedicated streaming port. To disable the port, set it to 0."

I have been unable to get this to work, although there is data there (I telnet'ed to it, and there's a ton of data flying out)

I suspect I'd get better performance with the streaming jpeg on port 8001, and would like to try it.

Does anybody have any suggestions on how to access the video stream on 8001 from Zoneminder?

Thanks!

Terry

try using mplayer on the 8001 stream see if it tells you what format it is, i would assume it wouldn't be mjpeg as i can't see them using such a horrid web server it cant do mjpeg through itself properly.
