Hello everybody, i have installed a dahua dvr in a remote place and i am connecting over the internet to watch the isnstalled cameras, but i realized that there is difference in the quality from camera to camera...In the settings i see that in the first channel when i choose D1 resolution the maximum frame rate is 25 an maximum bitrate is 4096, but in the rest 7 channels in D1 resolution the maximum fps is 6 and maximum bitrate is 1024... Why is that happening ? The current BIOS Version is 2.908.0000.1, Build 2012-2-15.. I have to do any update ?
