A number of perceptions about PTZs exist within the marketplace. Many of these were valid at one point, and some do continue to be true today. However, there are several misperceptions that should be addressed.
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.
