Introduction

r r

Police cars around the world are equipped with a variety of advanced cameras and systems designed to enhance safety, enforcement, and communication. These technologies play crucial roles in crime prevention, traffic management, and ensuring public safety. This article focuses on the different types of cameras mounted on top of police cars and the systems that use them, particularly in the United States and the United Kingdom (U.K.).

Understanding Camera Systems on Police Cars

r r

One of the most common camera systems on New York City (NYC) patrol cars is the Automatic Number Plate Recognition (ANPR) system. Unlike the trunk-mounted cameras that primarily serve as part of a plate reading system, ANPR cameras continuously scan license plates for specific information. These cameras are particularly useful for law enforcement during routine patrols and stops.

ANPR in the United Kingdom

r r

In the U.K., ANPR systems are widely used. These camera-equipped police cars constantly monitor the license plates of vehicles in the vicinity. When a vehicle of interest is detected, such as one connected to criminal activity or one that is not insured, the system alerts the officers. This instantaneous information allows officers to make better-informed decisions before approaching a vehicle.

r r

Capture of Vehicle Information

r r

The ANPR cameras capture the vehicle's registration details and immediately send this information to the National Crime Information Center (NCIC). The system can check the plate number for active warrants, stolen vehicles, and other types of information. This process is highly valuable for officers as it provides them with a wealth of information about a vehicle's registration, owner details, and recent activity.

r r

ANPR during Routine Stops

r r

When ANPR-equipped police cars stop someone for a "chat," officers have a significant advantage. They can quickly and efficiently check the vehicle's registration details, including the registered keeper's name, address, tax status, and MOT and insurance information. This streamlined process eliminates the need for lengthy administrative and bureaucratic checks, making the enforcement process faster and more efficient.

r r

Opticom Systems in the United States

r r

Another technology commonly found on police cars is the Opticom system. This advanced system is designed to improve traffic flow and safety. A flashing white light is mounted on the roof of police, fire, and ambulance vehicles, and it works in conjunction with a radio signal from the vehicle. When an Opticom-equipped vehicle approaches, the system triggers the traffic lights to change to green, allowing the emergency vehicle to pass through safely and quickly.

r r

How Opticom Works

r r

The Opticom system functions as follows:

r r r Flashing Light: The white flashing light mounted on the roof of the vehicle is visible to traffic signals.r Radio Signal: The radio signal sent from the vehicle communicates with the traffic light controller.r Traffic Light Change: Upon receiving the signal, the traffic light changes to green, allowing the emergency vehicle to proceed.r r r

Advantages of Opticom

r r

The Opticom system offers several advantages, including:

r r r Improved Safety: It helps ensure that emergency vehicles can reach their destinations quickly and safely, minimizing response times.r Enhanced Efficiency: Traffic signals are managed efficiently, reducing congestion and improving overall traffic flow.r Public Awareness: The flashing lights and signals increase public awareness of emergency vehicles, which can encourage safer driving.r r r

Other Camera Systems

r r

There are various other camera systems developed for police cars, including those that use license plate recognition technology from multiple angles. These systems can automatically input license numbers into the NCIC and check the plate number for active warrants and stolen vehicle information. Many manufacturers produce these systems, and they typically include some type of camera technology.

Conclusion

r r

The cameras and systems installed on top of police cars are sophisticated and essential tools for modern law enforcement. From ANPR in the U.K. to Opticom in the U.S., these technologies enhance the efficiency and effectiveness of police work. By providing real-time, detailed information, these systems help law enforcement officers perform their duties more effectively and with greater precision.
