If you need to be able to focus on certain points of an area at any given time is essential, the solution is the Pan,Tilt, Zoom (PTZ) also known as the Speed camera. These cameras can be controlled remotely, change zoom level and moved in any direction via a keyboard or joystick. Other ways of controlling the PTZ's are through the DVR Security System using a mouse or even via an Infra Red remote control.
It is also possible to connect a motion PIR (passive infrared sensor) to the PTZ 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.
