* [[Toll road|Toll]]-booth cameras to identify vehicles proceeding through a toll booth without paying the toll
* Turn cameras at intersections where specific turns are prohibited on red. This type of camera is mostly used in cities or heavily populated areas.
* Automatic number-plate recognition systems can be used for multiple purposes, including identifying untaxed and uninsured vehicles, stolen cars, and potentially [[mass surveillance]] of motorists.<ref name="misuse"/>
* Bus lane cameras that detect vehicles that should not be in the bus lane. These may be mounted on buses themselves as well as by the roadside.<ref>{{cite web|url=https://www.tfl.gov.uk/modes/driving/red-routes/rules-of-red-routes/bus-lanes|title=Bus lanes|work=tfl.gov.uk|url-status=live|archive-url=https://web.archive.org/web/20150317163849/https://www.tfl.gov.uk/modes/driving/red-routes/rules-of-red-routes/bus-lanes|archive-date=2015-03-17}}</ref>

Fixed camera systems can be housed in boxes, mounted on poles beside the road, or attached to [[Gantry (road sign)|gantries]] over the road, or to [[overpass]]es or [[bridge]]s. Cameras can be concealed, for example in garbage bins.<ref>{{cite web|url=http://english.controleradar.org/hidden-speed-camera.php|title=Hidden speed camera|website=English.controlRadar.org|access-date=2016-06-30|url-status=live|archive-url=https://web.archive.org/web/20160715131927/http://english.controleradar.org/hidden-speed-camera.php|archive-date=2016-07-15}}</ref>

[[Mobile speed camera]]s 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 velocity|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]].

Some number-plate recognition systems can also be used from vehicles.<ref>{{cite web|url=http://sensordynamics.com.au/MobileANPRSolutions/tabid/56/Default.aspx|title=Vyper Mobile ANPR System|publisher=Sensordynamics.com.au|access-date=2008-05-31|url-status=dead|archive-url=https://web.archive.org/web/20080724012408/http://www.sensordynamics.com.au/MobileANPRSolutions/tabid/56/Default.aspx|archive-date=2008-07-24}}</ref>
