Hi there. Have had an 8 camera 960H system working beautifully for some time now.
Today I replaced the DVR with a new unit (DT81DP) and changed four cameras to 8MP units. All this was supplied as a kit. Four of the old cameras remain connected to the other four inputs.
The four old cameras work perfectly. The four new cameras work perfectly when set at any resolution up to 5MP but when set to 8MP, I get rolling dark lines down the screen. I have played with every setting I can find but this seems to be a problem I can't solve. I do not appear to have anywhere to choose between PAL and NTSC so assume these devices are playing nicely with each other.
The only aspect that seems odd is that whilst the system recognises the 8MP feed, I note that in the "Signal Input Status" part of the Camera menu, the entry is listed as "5MP Long Distance Transmission". Perhaps this is not relevant.
Any advice appreciated.
To recap, all works fine if I set to 5MP, but at 8MP I get horizontal line interference.
