All kind of existing automated camera.
Speed limit camera:
Speed cameras are used to monitor compliance with speed limits, which may use Doppler radar, LIDAR or automatic number plate recognition. Other speed enforcement systems are also used which are not camera based.
Fixed or mobile speed camera systems that measure the time taken by a vehicle to travel between two or more fairly distant sites (from several hundred metres to several hundred kilometres apart) are called automatic number plate recognition (ANPR) cameras.
These cameras time vehicles over a known fixed distance, and then calculate the vehicle’s average speed for the journey.
Red light camera
A red light camera
is a traffic camera that takes an image of a vehicle that goes through an intersection where the light is red. The system continuously monitors the traffic signal and the camera is triggered by any vehicle entering the intersection above a preset minimum speed and following a specified time after the signal has turned red
Bus lane camera
Some bus lane cameras
use a sensor in the road, which triggers a number plate recognition camera which compares the vehicle registration plate with a list of approved vehicles and records images of other vehicles. Other systems use a camera mounted on the bus, for example in London where they monitor Red routes on which stopping is not allowed for any purpose.
Mobile speed camera
Mobile speed cameras
may be hand-held, tripod mounted, or vehicle-mounted. In vehicle-mounted systems, detection equipment and cameras can be mounted to the vehicle itself, or simply tripod mounted inside the vehicle and deployed out a window or door. If the camera is fixed to the vehicle, the enforcement vehicle does not necessarily have to be stationary, and can be moved either with or against the flow of traffic. In the latter case, depending on the direction of travel, the target vehicle’s relative speed is either added or subtracted from the enforcement vehicle’s own speed to obtain its actual speed. The speedometer of the camera vehicle needs to be accurately calibrated.
