Pan Tilt Zoom, or PTZ cameras are a common solution for an active surveillance, which involves security guard presence. PTZ cameras can pan, tilt and zoom. They can follow pre-set patterns or be manually controlled by a security personnel. With the optical zoom built-in on most of the models, operator can zoom-in on the desired subject, from hundreds of feet away. New models have built-in AI as well, adding additional feature like line crossing detection, target detection, advanced motion detection, target tracking. PTZ cameras are a great solution for a surveillance of any large open spaces, like parking lots, airports, sport's stadiums, farms or golf courses and similar. As good as PTZ cameras are, there needs to be a reason for using them. We often see PTZ cameras being used the same way as fixed cameras. With an average price of a PTZ cameras being more than the price of 4-5 fixed cameras, it important not to use PTZ's where their full potential will never be utilize. Often it makes more sense to install a few fixed cameras, then trying to cover "too much" with one PTZ.
