As the industry continues to shift from standard definition to HD and megapixel video, “digital zoom” has become a major selling point. With a high-definition camera, you can continue to record an entire scene while zooming in digitally to examine a specific object or area more closely. With that in mind, there may be some in the industry who are wondering whether there’s still a place for pan tilt zoom (PTZ) cameras in security installations. Based on research and conversations with several dealers and integrators, that seems to be true, and there are a lot of reasons for that beyond digital zoom.
