PTZ Surveillance System

What are PTZ ?

A pan–tilt–zoom camera (PTZ camera) is a camera that is capable of remote directional and zoom control (using manual or automatic control), enabling wide area coverage and accurate detail of the image when zooming in. A  PTZ camera usually has the ability to pan 360°, tilt 180° or 220°, and is often equipped with a zoom lens. (A zoom lens provides an optical zoom that maintains image resolution, as opposed to a digital zoom, which enlarges an image with loss in image quality.)

PTZ commands are sent over the same network cable as for video transmission (no need for RS- 485 wires as is the case with an analog PTZ camera). PTZ cameras with support for Power over Ethernet (PoE/PoE+/High PoE) also do not require separate power cables, unlike an analog PTZ camera.

PTZ cameras can come in various form factors; the most common is a PTZ dome, which is ideal for use in discreet installations due to its design, mounting (particularly in indoor, dropceiling mounts), and difficulty in seeing the camera’s viewing angle. In outdoor installations, the cameras are usually mounted on poles or walls of a building.

In operations with live monitoring, PTZ cameras can be used to follow a person or object, and zoom in for closer inspection. In unmanned operations, automatic guard tour on PTZ cameras can be used to monitor different areas of a scene. In guard tour mode, one PTZ network camera can cover an area where many fixed network cameras would be needed. The main drawback is that only one location can be monitored at any given time.
