It really depends on where the camera is mounted as it is a fixed camera.
You may be better off with the XX60A as it is a Pan &Tilt Zoom capable camera and is capable of viewing the area it would take 3 or 4 cameras to do.
The PTZ feature is well worth the extra price in my opinion.
You can see some screen shots from it in my
Airsight XX60A reviewThe zoom feature may be needed for you to identify exactly who is in view.
It is possible to auto move the camera to a pre-set with a x10 motion sensor and AHP as well.
