I have a IPC-T5442TM-AS that I generally like pretty well. I use it in H.265 mode, 10 FPS, with the Iframe interval at 10 as well. I have all the built-in detection stuff (IVS, etc.) off because I'm using BI.
The problem I'm having is that image quality seems to improve up to a bit rate of around 12000 (Kb/S), but at that rate, the camera loses framerate and there are breaks in the audio as well. For example, when set to CBR 20000 Kb/S, the camera will only push about 3 FPS at a bit rate of 1100 kB/s according to BI. If I set it to 10000, it picks up to about 6 FPS, at a bit rate of 1000 kB/s. The best setting I seem to be able to get reliable 10FPS is VBR, Quality 4, 10000 Kb/S max bit rate. If I set VBR to quality 6 and 12000 Kb/S max bit rate, the frame rate falls to around 5 or 6 FPS.
Is my particular camera defective, or is this a limitation of the T5442?
I'm running the most recent firmware, but it had this problem with previous versions as well.
