Traffic Camera vs Red Light Camera: 5 Differences & Types
In 2024 according to the insurance institute for highway safety, almost 1119 people died and 141000 injured in red light running crashes. Half of them were pedestrians, motorcyclists and in other cars.
To avoid these accidents, traffic cameras and red light cameras were introduced. But many people think that they are the same. To clear your confusion, we wrote this article for you. So, you will know the difference between them properly.
What is a Traffic Camera?
Traffic cameras are speed calming devices used to control traffic flow, adjust traffic signals timing and provide live video recording. You can also call it a video camera. You can install it in main roads, highways and intersections. These are connected by optical fibers and you have mounted it alongside and under the road.
You don’t need to worry about its blackout, because they are linked with the main power, solar system and other resources such as battery backup. That’s why they give you consistent imagery.
What Do Traffic Cameras Look Like?
You will see them in small, cylindrical tubes and dome shapes. These are protected by durable and weather proof housing. You will also observe that it contains elongated tubes and medium to large size domes. You can post it on the top of light signals, traffic light arms or poles which are almost 30 feet long.
How Do Traffic Cameras Work
Traffic cameras consist of high resolution lenses, sensors or radars which detect the movement of vehicles. The intelligent AI algorithm that is present in traffic cameras tells you about vehicle counting and congestion level.
If we talk further about its working, these cameras capture live road conditions. Next, send it to local transit systems such as the city traffic management network. Then the transit system changes the traffic signals based on the number of vehicles. In this way you prevent massive traffic jams and long waits.
Types of Traffic Cameras
Now we will tell you its important types after understanding the traffic camera explanation.

ANPR Cameras |
It reads the vehicle registration plate quickly, checks against its digital database. Then take automated action such as tracking stolen vehicles, issue fine or inform to police |
Highways, parking areas and toll plazas |
|
Traffic Sensor Cameras |
These cameras have smart sensors which are used to find the presence of cars. They trigger the changing of traffic lights, measure vehicle’s crowd and queue length. |
Intersections, freeway ramps and heavy traffic zones |
|
Automatic Traffic Recorder |
They tell you the total number and type of vehicles by weighing the axles. This prevents the road from being damaged due to overloading trucks. |
Main roads, bridges, interstate highways and tunnels |
|
AI Traffic Counted Cameras |
It acts like a smart human eye which uses a computer to scan pictures, count vehicles and classify the types. They also catch the violation of vehicles. |
Busy junctions, smart city zones and motorways. |
What is Red Light Camera?
A red light camera takes the images of vehicles if you violate traffic signals such as entering the intersection when the red light is on. You can call it a traffic enforcement camera.
You can mount it on intersections and busy zones. It captures two photos firstly when you enter and secondly while you are crossing the junction. These pictures are evidence which helps the authorities to enforce the traffic law. These are posted to change the behaviour of drivers, reduce accidents and increase your safety.
What Do Red Light Cameras Look Like?
What Do Traffic Enforcement Cameras Look Like? It commonly has rectangular or box-style metal housing which is highly weather resistant. You can see red light cameras in various colors such as grey, yellow, silver and black. You can install it on tall poles before junctions and traffic light rods. In addition, it comprises a round glass which covers a dark coloured lens, small flash unit and overhead sensor.
How Do Red Light Cameras Work
Red light cameras use sensors like in-ground inducting loops or radar which is connected to a traffic controller. You will activate the system when you cross the stop line after the red light turns. As a result, it catches a short video or at least two photos of your violation and license plate.
Furthermore, it also records time, date and vehicle speed. After recording data, the enforcement camera sends it to a centralized processing center such as a police department. They review the evidence first and then the ticket is mailed to the registered vehicle owner.
Types of Red Light Cameras
Below are the common types of red light cameras. These cameras work 24 hours a day and 7 days a week.

|
Dual Red Light Camera |
When you do not follow the red light traffic rules,it takes your vehicle picture from two different angles by creating clear flash. That’s why it is known as a dual red light camera. |
Junctions and accident prone areas |
|
Portable Speed Camera |
Mobile cameras can be moved, set up in cars, vans, tripods and handheld devices. Its lens, radar and laser technology measure speed and capture the image of overspeeding vehicles to enforce speed limits. |
School zones, residential streets, construction sites and highways |
|
Speed Cameras |
It also uses radar, laser and sensor to detect overspeeding vehicles and make the record of licence plate, speed, date and time to issue e-challan. |
Major highways, urban expressways and school regions |
|
Point To Point Cameras |
These are also famous as average speed cameras. They calculate your average vehicle speed by calculating the journey time between two fixed points using an entry and exit camera. |
Long stretches of motorways, tunnels and ring roads |
|
Fixed Red Light Cameras |
They are an automated system permanently mounted on a pole to detect the vehicles that proceed to the stop line while traffic is red. It feeds every minor detail of your vehicle. |
Intersections, motorway and school locations |
Comparison of Traffic Camera vs Red Light Camera
1. Purpose
You can use a traffic camera to monitor the flow of traffic, volume and congestion. They collect the data, adjust traffic lights timing and enhance the road safety for you. Whereas, red light cameras create a photo or video clip of your vehicle with a number plate when you ignore a red light. Then it will mail a citation to you (vehicle owner) if you are found in violation of law.
2. Enforcement Capability
A traffic camera is a non-enforcement system. It does not record driver identities and issue tickets. On the other hand, red light cameras strictly enforce the rule. It delivers you a notice or fine when you break the rules of red light. So, we can say that traffic cameras manage the vehicles movement and red light cameras focus on violation and implement rules.
3. Placement
To get a wide view of the intersection for measuring vehicle density, you can mount the traffic camera on the top of the traffic light arm. In contrast, you can install red light cameras on separate elevated almost 3.6 meter high poles. You need to place them roughly 20 meters before the junction. Wire or loop connected to it buried under the asphalt just behind the white stop lines.
4. Moderen System Integration
Artificial intelligence and cloud data based traffic cameras calculate vehicles, detect speed, note the congestion level and connect to smart city traffic. As a result, they observe traffic patterns to help you to improve future road design if you are an urban planner.
However, red light cameras contain digital sensors and automated licence plate recognition software. They read registration numbers from feed images and also link to municipal ticketing platforms.
5. Activation Mechanism
Loop wire attached to traffic camera mount under the ground. When you drive over them it activates to detect and count the vehicles. But the sensor and radar in lane triggers a red light camera only when you go through the stop line. Then it charges you a heavy penalty due to disobeying the rule of red light.
To Summarize
We hope you got complete knowledge about the comparison of traffic cameras and red light cameras. Now when you drive on the road, you must follow the traffic rules to avoid fines. So that you and other people remain safe. Furthermore, if you have any questions or need traffic control products then you can contact us. Our engineering team provides you the best solution.
