PTZ Cameras: The Basics

When it comes to security cameras, there are various types that work better in certain situations than others. Thanks to their specialized functions, PTZ cameras are ideal for monitoring large, high-traffic areas.

PTZ stands for Pan, Tilt, and Zoom, which means these security cameras can provide improved surveillance. These functions can be controlled manually (via monitoring software or a joystick) or automatically (via camera management software). Actively keeping an eye on the feed and the ability to manipulate the field of view means security staff can respond to any incidents that may arise quickly.

When employing camera management software, you have the option of setting up guard tours, which enables the camera to automatically move to set locations on a schedule. In addition, some PTZ security cameras offer auto-tracking, which can automatically follow a moving target (such as a person or car).

How Does PTZ Work?

Pan

• The camera can swivel left and right for a wide area of coverage.
• Pan can range up to a complete 360 degrees or less.

Tilt

• The camera can tilt up and down for a wide vertical range of coverage.
• Tilt will vary by camera model, with a maximum of 180 degrees.

Zoom

• Optical zoom physically adjusts the camera lens (by changing the focal length) to zoom in and out (allowing the camera to maintain image quality).
• The amount of optical zoom is expressed as #x (ex. 18x), which represents how much the camera can zoom (change the lens focal length).
• Digital zoom blows up the image using software. This often results in pixilated images when zoomed too far, and thus, is not recommended.

As previously mentioned, PTZ cameras are ideal for surveillance of large areas including parking lots, common areas in schools or businesses, and convention centers. You may monitor the overall area while zeroing in on any suspicious activity. When paired with fixed network cameras that handle important locations such as entrances and exits, you can create a very flexible and functional surveillance system. With the fixed cameras maintaining an eye on vital points, the PTZ cameras are free to move around as needed. Furthermore, PTZ cameras are available for indoor or outdoor use in a variety of styles (but most commonly dome style).
