I have a Dahua HDW5231R-ZE 2MP cam doing side of house 20' up over watch duty. I have a Dahua B5442T-AS as 8' high low height duty catching the same area.
This recent (as of 1 week ago) issue is night and IR. When I view the 5231 at night, it's pitch black...as in, no IR light visible shining anywhere. However, when I view the 5442, I can see the 5442's IR light and the 5231 IR light. I have verified this by turning on/off the 5231 IR light while watching the 5442. Yes, it blinks on and off from the topside of the 5th wheel. I have factory reset the 5231, no joy. Very perplexing.
I bought these 5231's from Andy as my first 4 camera's last year. I have not checked if any firmware is available to upgrade. My other 3x5231's work AOK with IR lighting.
