All analog 700TVL camera works great both day and night, problem is AHD camera that have HD-269-A0 board . This is 3MP hybrid board like this: http://www.ruision.com/prod_view.aspx?TypeId=75&Id=199&FId=t3:75:3. I have external IR illuminator and second camera (analog) which illuminates my garden (place which is looking AHD cam) but still night vision is dark or totally black.
I check IR cut and it looks and works fine. When sunset view is going to black& white and you can hear a click (IR cut).
I suspect that problem is some parameter/setting in OSD.
For better understanding this issue I take some screen shot
1 - picture taken in the day for both cam (analog and AHD)
HD269-A0 camera board 3MP (night vision issue)
