I wasn't sure if you were running LPR software or just recording. I agree if your running the software, keep the resolution lower for it to process, but if your just going to an NVR and recording license plates with one camera, and general area with another, than it's safe to use a higher megapixel camera for just the plates. If you need something with crazy zoom, than you might want a PTZ. Or, set up a wifi bridge and install the camera closer to your object.
