Auto-tracking is a great analytics program. This is an analytic available for Pan/Tilt/Zoom cameras. It allows for the camera to identify an object and follow the object across its field of view. The camera will zoom on the subject to get the highest resolution image possible, and track it across the entire area. No intruder will have a chance to be undetected in your yard. Auto-tracking is a very sought after analytic, because it allows for the capture of the smallest details without having to manually control the camera. Guards are no longer necessary if you have an auto tracking enabled PTZ camera.
