I have a modern Dahua 2MP PTZ about 10 months old. I have setup to RTSP pull into Wowza and that works great. The only issue I'm having is with grabbing snap shot photos from it over HTTP. I found digging around google that this is the way its being done by others:
http://192.168.1.108/cgi-bin/snapshot.cgi?1
This works, but it is unreliable. I'd say it fails 50% of the time with "HTTP 500" error.
Do any of the Dahua gurus lurking here know of an issue with snapshots and if there is another method I should be using to grab still frames over HTTP?
Thanks,
Brian
