Marius on Sibell HDOB-SB2IRZW CVI/TVI

Thanks will do today evening.

One more question:

Are the BNC channel inputs on the DVR paired? Somewhere I read (not sure if this is applicable to my DVR) that the inputs on a BNC channel pair , like 1+2 or 3+4, etc. have to be the same signal quality. If not the DVR will downscale it to the lower. So, should I put my HD camera on a separate input channel, not next to an analog signal?

Thanks!
