In some cases, your CCTV video may not be very clear and it may have waves on the monitor. It depends on the camera and display capabilities, as well as the bandwidth and the high frequency amplitude and phase response of the transmission medium.

When comparing megapixel camera specifications you may notice pixel counts slightly different from the above. None of the equipment should be grounded, do not connect ground pin to earthning pin. Can you provide an image of what's happening? The good news is that identifying the problem isn't as difficult as you may think.
The higher the resolution, the better an image will be. If you find yourself with a product using the contradicting system, it will be blatantly obvious the second you power the camera on.
