Anyone have this problem and if so, how was it resolved?
What model? I have a lot of problems with the Arecont AV8185DN, more so than any other model of camera. And yes, even though our streaming code works with other brands, doesn't mean it will work with the Arecont. From memory, these were the problems I had:
1) Appears to emit h264 that crash Intel h.264 IPP decoders on some processors. I do not know if this is Intel at fault or Arecont, but the problem seems to have been there since at least 2009:
UMC H264 decoder crashes on decoding Arecont H264
2) The AV8185DN multi-imager ( at least the one I have on my bench) seems to drop the connections very easily if you connect with a seperate tcp connection for each of the 4 streams (i.e. 4 tcp connections per camera). However they support streaming all 4 video channels over a single tcp (rtsp) connection, and this seems to result in a more stable connection.
3) I had another problem where the tcp connection wouldn't connect, can't remember the details, but I had to change some of our tcp code to so it accepted a packet in a single read, rather than segmented into seperate reads (or it was something like that...). I didn't think we were doing anything wrong there, and got the feeling there were some strange goings-on with their socket code.
You can get it to work, but it requires a lot more work than with other cameras...
This reminds me of a problem we had getting 20+ frames per second out of an Arecont several years ago. This was a box camera. Turning off the Sony cameras would allow the camera to go full frame rate. The Sony's never had a problem doing full framerate. Bandwidth should not have been an issue and it was not a lot of cameras.
What we eventually found as a work around was putting the Arecont on it's own network connection direct to the NVR. It did not seem to like being on a network with other cameras.
Large enterprise customer here...
This all sounds familiar. I have wrestled with Arecont for almost 5 years.
After years of unresolved service calls by my integrator, failed tech support calls with Arecont and discussions with local reps who denied the issues with these cameras, I decided to replace all Arecont cameras with Axis Q3709.
So far, no problems at all with my Axis 180 degree cameras.
