    Hi, trying to adjust the PTZ5A4M-25X bit rate

    95Mbps is insane. That's why I hesitate to use it, it is unpredictable and unbounded, until something gives out.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    I wonder if the maximum bit rate is affected by other functions such as IVS/movement detection? I am not using any yet.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    With 30fps and I frame interval of 30 the bit rate can go up to 16384. With H265 it only goes up to 10240. For now I will just use the API to set it to 21Mbps and see how it goes. I just have to remember setting it again after I use the web interface...

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    I think the 5442 hardware is reaching it's max at around 16384 Mbps and there is no spare room for ROI at that speed. If a lower bit rate is used, adding ROI will probably increase the bit rate. The PTZ5A4M-25X hardware seem to have a lot of spare room for higher bit rate but the web interface...

    Here it is. 5 sec clips, one is 28.9MB, the other 6.1MB.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    I tried H.265 but even at over 50mbps, I thought the quality was better with H.264.H. I will try to upload a video at 11 and 50Mbps....

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    Yeah, those are screen capture from UI3, the difference is visible. I can upload full resolution picture if you think that will help. The camera seems to struggle at over 65Mbps, I take the bit rate from here:

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    I am running B/W but the problem is the same...I might add some IR emitters at some point. Here are 2 daytime images I just took, one is at over 50 Mbps the other at 11Mbps.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    I use a max of 1/60s at night. I can't currently use the illuminator because of my setup so this is only far away street lights. The 3D filtering was set to default of 50 a few days ago and I thought the image was super smooth at 11Mbps... until a couple of wolves showed up and they were quite...

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    For instance, at low light at night without using excessive filtering, there is quite a bit of noise and using 12mbps is not enough to get fine details, they are just blurs. I have a few IPC-T54IR-ZE S3 and I wish I had a bit more than 16Mbps at night to get finer details in a couple of them...

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    No difference with Chrome, Firefox, Edge or internet explorer mode in Edge.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    OK, reducing the I frame interval from 30 to 15 allows me to increase the bit rate to 11776, but that's still quite low for my situation.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    My web interface limits the bit rate to 9728 (Kb/s). Both CBR and VBR set at 9728 result in a maximum bit rate of about 9Mbps out of the camera, irrespective of image content.

    Hi, trying to adjust the PTZ5A4M-25X bit rate

    Hi, I have been slowly building my system over the last few months and my last camera is the PTZ5A4M-25X. I like to continuously record my other cameras at maximum bit rate but I am struggling with that one. The web interface maximum bit rate is 9728 Kb/s which I thought was a bit low...
