What are you looking at? Optical vs Digital Zoom
When selecting a camera, it’s important to consider the scene the camera will be observing and what performance characteristics are expected from the CCTV cameras. Some folks ask for a very wide angle lens so that they can see as much as possible from one camera. That’s great, but if the expectation is also to read license plates or identify a person’s face from 100′, then we’ll need to consider optical vs digital zoom.
