NEED HELP( using both analog and AHD cameras on AHD DVR)

[sholagentle 0]

hello everyone,

Kindly help to resolve this issue:

I troubleshoot an 8cameras system (8 analog cameras) and discovered 4 cameras bad, I went to buy 4 AHD cameras (for replacement) but they refuse to work with d dvr while d other existing 4 analog cameras are working. I was told d AHD camera can only work with AHD DVR,

To solve d problem, I bought AHD DVR , but having another issue.

My connection goes thus:

Analog cam on channel 1, 2, 3 and 5,

AHD cameras on channel 4 and 6.

I have used a separate power (close to d camera) for the AHD cameras so loss is not an issue. Other cameras also have enough current.

Observation:

If no AHD cameras are on, channel 1,2,3 and 5 (which are analog) will work.

If u switch off cameras 1,2,3, and 5, camera 4 and 6( Which are AHD) will work and if u switch on camera 1,2,3 and 5 while 4 and 6 are on, only two cameras ( 1 & may be 2) will show . meaning only 4 cameras come on/display on the ahd dvr at a time, either d 4 analog or two analog and two AHD cameras. This seems strange to me, what could be d problem and how do I solve it. Thanks

Put the analog cameras on 1-2-3-4 and the AHD cameras on 5-6.

 

Some cheap units can only support channel in pairs. That means that if CH3 is analog, CH4 also has to be analog. If CH5 is AHD, CH6 also has to be AHD.
