You’re being watched. But not in a creepy Black Mirror episode kind of way. Ever wonder what traffic cameras are doing? Who’s watching, and why?
Let’s get into this less-discussed aspect of modern-day driving & explain the differences between traffic cameras, cameras on red lights, and speed sensors.
Non-Enforcement Cameras
Non-enforcement cameras are your silent companions, always watching but never giving out a red light camera ticket. Examples of Non-Enforcement Cameras include: Traffic Sensor Cameras & Automated Number Plate Recognition (ANPR) systems.
Traffic Sensor Camera Systems
Traffic sensor cameras are the most common yet least discussed members of the traffic surveillance family. You’ll find these cameras perched on top of traffic signals or high on light poles along the roadway. They are on the job day and night to monitor traffic flow to determine optimal traffic light timing. These cameras play an important role in managing traffic congestion and optimizing signal timings, significantly influencing your daily commute.
Automated Number Plate Recognition (ANPR)
Now let’s talk about ANPR cameras. Their job is to read license plates – they record video for the purpose of recording license plate numbers driving through an intersection. They can be mobile (like in a police cruiser) or stationed at fixed locations. These cameras feed valuable data back to control centers, enabling the tracking of vehicle movements.
If a police officer unknowingly pulls up behind a driver with an outstanding warrant, his ANPR system reads the vehicle’s plate, cross-references it with the database to tell the officer who he’s dealing with.
Some argue it’s a bit authoritarian or big-brother for government databases to have this information. While others will say it’s a necessary evil – what do you think? Let us know in the comments.
Automated Traffic Enforcement Cameras
Now, meet the enforcers. The enforcement cameras play a more assertive role in traffic management – the red light cameras and speed sensors.
These are primarily installed in residential areas where children play on the streets (but some drivers insist on speeding through). Automated traffic enforcement cameras are the ones mailing those surprise tickets.
The installation of a speed camera can get rid of this kind of behavior & increase the safety of the community.
Red Light Cameras
Ever think you could beat a yellow light, but didn’t? A red light traffic camera could’ve been watching. Red light traffic cameras are stationed at busy intersections to catch red light violators.
Despite controversy surrounding them in some US states, red lights cameras play a pretty big role in helping road safety. Red light cameras work by capturing a license plate of drivers who didn’t follow the correct traffic signal.
Red light cameras look like a bulky camera box stationed on top of a traffic light or electrical poles at a busy intersection. If you’ve ever gotten a red light ticket in the mail, a red light camera is probably why.
The best way to fight a red light ticket in the mail is with your own dash cam footage, check out our best dash cam list if you don’t have one already.
Traffic Light Speed Cameras
A speed camera, like a red light camera, has a significant influence on road safety. They’re a video camera mounted to a traffic light but don’t have the same technology as red light cameras.
Traffic and video cameras use radar detection. Within the traffic signal video cameras, a radar detector is being used to track speed to make sure you’re not speeding through an intersection (even if it’s a green light).
Fixed Speed Cameras
Ever noticed a bulky, weatherproof camera mounted on a roadside pole or light post? That’s a fixed speed camera. Law enforcement typically installs a speed traffic camera on back roads or in residential areas.
The best chance you have of beating a ticket from a fixed speed camera is with your own video proof, yet another reason to get a dash cam. They’re designed to catch drivers speeding through areas with low speed limits, instead of catching red light violations.
Mobile Speed Cameras
There’s one last type of law enforcement camera we haven’t talked about yet – mobile speed cameras. Mobile speed cameras installed are harder to spot and always on the move, like those mounted in a van or stationary police vehicle (ie speed trap). They’re set up by local police officers in an effort to decrease speeding violations on a road known for speeding.

Other Camera Systems
The most common type we haven’t yet mentioned are the radar detectors attached to speed signs and stop line sensors. When there’s an uptick in vehicle ticketing at a non-intersection or rural area, radar detectors on speed signal signs are what’s used.
FAQ
Traffic surveillance uses various types of cameras including red light cameras, speed sensors, traffic sensor cameras, and Automated Number Plate Recognition (ANPR) cameras. Red light cameras and speed sensors are used for enforcing traffic laws, while traffic sensor cameras and ANPR cameras are used for monitoring traffic and tracking vehicle movements.
Cameras on top of traffic lights are typically traffic sensor cameras. They measure traffic flow and help determine the timing of the traffic lights to optimize traffic conditions. These cameras do not issue tickets or fines, their primary purpose is traffic management.
Yes, some traffic lights in Texas have cameras. These traffic cameras are typically red light cameras used to monitor intersections and detect speeding violations. However, use of these cameras has been controversial, and some Texas cities discontinued operating.
Yes, red light camera tickets are considered administrative violations, similar to parking tickets. If you choose to ignore the red light camera ticket, it will not result in criminal charges or a warrant for your arrest, but it could be sent to collections and could affect your credit.
Access to traffic camera recorded video footage varies by jurisdiction. You might need submit a request to the local traffic department, law enforcement agency, or city government, depending on who operates the cameras. Read about it more in our article about how to request dash cam footage. But keep in mind many traffic sensor cameras don’t archive footage unless it caught you speeding in the first place.
Embracing Road Safety
Traffic cameras, red light cameras, and speed sensors seem like creepy spectators of our daily lives on the road, but they’re pretty important. For safety, traffic light efficiency (so you’re not stuck at a red light forever), and management of our roadways in general. They aren’t only for law enforcement but to ensure safer travels.
But hey, if law enforcement can have a camera everywhere – so can you. Read some of our dash camera reviews to get a feel for what to look for in a dash cam. I recently tested one of Amazons’ best selling dash cam for a month, read my complete Rove R2 4k dash cam review to learn more about its pros and cons.
Traffic cameras can seem intrusive but play an important role in the overall societal driving experience. From red light cameras catching those trying to beat the system, to traffic sensor cameras smoothing out the flow of traffic, it’s hard to say they aren’t useful. But in my opinion, it’d be better if everyone had their own dash cam. After all, dash cams are legal in all 50 states (even though there’s stricter laws in certain jurisdictions).
