One common question we often hear asked is whether speed cameras flash when they capture a speeding offence? Here’s what we know about the types of speed cameras and their flashes.
Mobile Speed Cameras
Mobile speed cameras are frequently moved between locations across Adelaide and are highly effective in detecting speed. Unlike fixed cameras, mobile speed cameras typically do not emit a visible flash when capturing an offence. These cameras often use infrared technology, which means any flash emitted is invisible to the human eye. This allows for discreet monitoring, especially beneficial in high-traffic zones and suburban areas where sudden flashes could be distracting or potentially dangerous.
Fixed Speed and Red-Light Cameras
Fixed speed cameras, often installed at intersections and frequently doubling as red-light cameras, operate differently. These cameras usually do have a bright white double flash that is visible to drivers, even during the day. This visible flash serves a dual purpose: capturing clear evidence in both day and nighttime conditions and providing an immediate deterrent to speeding and red-light violations.
Why the Difference?
The difference in flashing behaviour between mobile and fixed cameras isn’t just about their location or purpose—it also comes down to the different technologies and camera systems being used. Mobile speed cameras rely on newer, less conspicuous systems such as infrared as a flash and radar to detect speed, while fixed cameras are often older systems using sensors built into the road to detect speed and red-light offences and are designed to ensure reliability and effectiveness across a range of traffic and lighting conditions.
Regardless of whether a speed camera flashes visibly or not, all cameras are designed to for improving road safety. The best approach for drivers is to always obey the posted speed limits and drive attentively, as any type of speed camera—visible flash or otherwise—is there to monitor and encourage safe driving.
