I picked up the IPC-Color4K-X-6MM in spite of some complaints with image quality and overall I've been happy with it for watching wildlife, both day and night. However, I tested it for watching the end of my driveway it is just a little too wide FOV to make license plates clearly visible so I think I'm going to keep it as a wildlife camera. If I want something with comparable night performance but maybe 1.5-2x more zoom, what should I be considering? Should I be looking at fixed or varifocal?
