In large external areas, e.g. car packs the use of a Pan,Tilt, Zoom (PTZ) camera can be highly effective, providing the benefit to be able to focus on certain points of an area at any given time.

These cameras can be controlled remotely, change zoom level (typically 10X up to 36X) and moved in any direction via a keyboard or joystick. Other ways of controlling are through the DVR Security System using a mouse or even via an Infra Red remote control.

The PTZ Camera is often used to visually patrol a wide area with preset to switch between certain areas in a loop. Whilst in this type of loop it's possible to take manual control at any point to focus on a particular area of interest and return to the preset loop after a set amount of inactivity. It is also possible to connect a motion PIR (passive infrared sensor) to the Speed Camera so when a person comes within the motion detection range the camera will automatically spin round to face that point. These cameras are ideal for car-parks, security gates/fences or any application where a large area needs to be monitored.
