When thinking about a camera, you generally want both the highest resolution and the largest S/N ratio you will get. The Signal to noise ratio is a Logarithmic scale so some time between 46 dB and 48 dB is a fairly large modification. If forced to select between a camera with a slightly lower resolution and even a high S/N ratio maybe camera using a higher resolution and lower S/N ratio, try to pick the one with better S/N ratio if you’re doing longer (500 ft+) cable runs. For shorter runs going using the higher resolution is fine.
CCTV can be purchased in four basic parts: the lens possibly cameras, DVR, monitor and cables.
