HD269-A0 camera board 3MP (night vision issue)

Recommended Posts

Hello,

 

First - my English is full of weak (I mean, it's not so good, I and others can expect).

 

Second - I've cheap monitoring system to secure my summer house

System is based on XM board AHB7008T-GS-V3 (http://p.globalsources.com/IMAGES/PDT/SPEC/257/K1152616257.pdf) and mixed analog with AHD camera.

 

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)

2 - when getting darker

3 - in the night

Please write any suggestion.
