I pulled the 5442 into the house and gathered more data. No IVS improvement. Went back to the totally reliable hacked chinese camera outside. I spent all afternoon trying every combination of settings I could think of, 3 different firmware versions, reloading the yellow triangle license, and IVS works exactly the same in every case. So far, I've been denying that it could possibly be a hardware issue because I figure all of the IVS is firmware driven, but maybe there's a video processing chip that could be bad or something like that. I managed to make a list of (I assume) unrelated bugs while experimenting. First a picture. There's an intrusion box and 2 tripwires set. I could not cause an IVS trip moving the envelope anywhere in the frame. The only way I could cause an IVS event was to stand up in front of the camera. The bug list follows the picture.
The bug list:
1. IVS events don't go into the camera log (by comparison motion detect events do)
2. When camera switches from night to day, a video tamper event is logged
3. IVS works with smart codec on. Is this a new feature???
4. When using my Firefox, I believe without a plugin, the images in the IVS setup screen are delayed by 10 to 60 seconds. When using Pale Moon with plugin, there's no delay.
