Pan-tilt-zoom (PTZ) cameras are built with mechanical parts that allow them to swivel left to right, tilt up and down, and zoom in and out of a scene if it’s equipped with optical lens. They’re typically used to monitor wide open areas requiring a 180- or 360-degree view, and deployed in guard stations where active personnel can operate them through a remote camera controller.

1. Prevent intruders from entering restricted areas 2. Deter vandalism, crime, and theft in public areas 3. Gain context about incidents that occur after hours 4. Remotely monitor areas of open space such as parking lots and stadiums 5. Reduce the need to hire additional security personnel

The choice between wired and wireless security cameras depends on various factors, and the decision ultimately comes down to your specific needs and preferences.

Remember to position the cameras at optimal heights and angles to ensure maximum coverage. Additionally, it's essential to familiarize yourself with local laws and regulations regarding video recording and privacy to ensure compliance.
