Do Cop Car Dash Cameras Record The Speed Of Other Vehicles? 

Many people ask if cop car dash cameras record the speed of other vehicles. These days, you can find most high-quality patrol cars with integrated digital dash cameras, capable of recording high-definition video and digitally storing it for later use. With regards to speed, these dash cameras automatically record real-time speed of every car that passes by the police vehicle. 

However, some readers think a cop car dash camera should record the speed of cars going against the direction of the cop car. The answer is yes. It can record vehicles going in the opposite direction.

Accuracy Of Dash Cam Recording Speeds 

One thing to keep in mind concerning cop car dash cameras is their speed recording capability. It is not accurate because the speed of a given car may vary according to traffic conditions and weather. On the other hand, there are patrol units with integrated digital dash cameras that focus on only one type of vehicle in front of them, such as emergency vehicles. With regard to these types of patrol cars, the cameras have been designed to record only emergency vehicles.

Another reason that hampers the speed recording of vehicles can be the type of camera installed in the patrol car dash. The greatest number of police units use digital dash cameras that record the speed of cars passing by them. These cameras use high-definition video recording technology combined with the help of an inbuilt GPS receiver to record the vehicle’s speed. This makes it easier for officers to identify a given vehicle after an accident or violation. Some cameras with low-image resolution and quality cannot record the speed consistently.

What Is The Maximum Speed That A Dashcam Can Record? 

One significant thing to remember is that most integrated digital dash cameras can only record a speed not exceeding 100 mph. This is determined by the specs of most cameras available on the market. However, even if there are integrated digital dash cameras that can record a speed of 200 mph, it will not be adequate. The highest speed recorded by car dash cameras varies from unit to unit according to the manufacturer and its model.

Can a Dashcam Record Two Different Vehicles Simultaneously?

It can’t be done because the car dashcam registers each speed value as a separate event. It’s not capable of recording two vehicles simultaneously. To record two vehicles at the same time, it is necessary to install two car dash cams on your vehicle. 

However, it is possible to record the speeds of two vehicles by a patrol car with an integrated digital dashcam.

How Do Dash Cameras Work?

First off, let’s take a look at how dash cameras work.

These devices have digital recorders installed into vehicles that collect and save video files in moving pictures and videos. There are many cameras on the market today, and most use CCD sensors (like those used in digital cameras). However, some use CMOS sensors (used in point-and-shoot photography).

Most of these devices have time and date stamping abilities, adjustable frames per second, and multiple video files. Dash cameras are all unique and have different features. Some camcorders can function in the daytime and night-time scenarios. Some act as a DVR (digital video recorder) with or without an SD card installed, while others have sound recording abilities.

Dashboard cameras are typically used to record daily travels that capture roadways like accidents or infractions by other drivers. Some may use their dashcam or car cam to capture other events and vacations, work events, hobbies etc.

How does the public view dashcam usage by the police?  

People’s perception of a dashcam is mixed. Some think it is a violation of privacy, while others think it protects the public, police, and officers from traffic violations. On the other hand, police departments have found it useful in collecting evidence, but some officers are concerned about public surveillance being used against them for traffic violations. This technology will continue to grow as more departments adopt it and the public learns about more ways to use the device for safety in moving vehicles. 

Some important points to consider about the public’s view on dashcams.

• The dashcams help keep officers safe from false allegations. (Remember, anyone, can file a charge against an officer.)

• It provides transparency and accountability of police in critical incidents. 

• The camera provides an unbiased record of events if there is a discrepancy or disagreement over what took place at the scene.

• It can help officers write driving citations and reports by having direct video evidence.

• It protects the public against non-compliance with traffic laws.

• It provides evidence for insurance claims, traffic violations, accidents and other events involving an officer’s actions on the road.

Cost of Dashcams

The market is full of different types, models and prices on dash cams. There are low-cost models which cost around 15$ and high-end ones which cost around 300$.

The average cost of a dashcam is about 70$ to 100$. These devices come in different colors like black, blue and red. They also have different modes of operation like night vision, parking mode etc. As for the difference in prices, it depends on the brand and type. So when buying a dash camera, check out which type would fit your budget and record the contents of the vicinity around the vehicle. 

These devices can be brought online from eBay or Amazon. Some of the companies that provide these devices include Garmin, Mio, Vantrue, and Sony.

What Is The Resolution Of Car Dashcams? 

There are different resolutions available for dashcams. It determines the clarity of the video captured by the camera, while its quality can determine how well an image is recorded. The resolution of a dashcam can be described as the total number of pixels (or dots) per square inch. The lower the resolution, the fewer details it will record and display in a single video or picture. 


Dash cameras have changed how police officers and drivers record events on the road. In the past, dashcams were not as popular as today. Most drivers installed these devices for their safety and protection from other motorists on the road. Today, it is common for law enforcement agencies to purchase and install these devices in their patrol cars. The public views dash cams positively, although some object to their use because of privacy concerns. As far as speed recording is concerned, different dashcams can record different speeds depending on the type of camera that is installed. 


Q. Are dashboard cameras legal?

A. Yes, they are legal, and the public has no right to object to their use by police or law enforcement agencies on the road. In fact, many people have installed these devices for their own safety in case of accidents or other events like theft on the roadways.

According to statistics, a dash cam can save thousands of dollars in damages from an accident that occurs due to the fault of another driver. However, it could also save you from being charged with a crime or help you prove your innocence if you are wrongfully accused of causing a traffic collision or accident.

Q. Which is the best dashcam model on the market?

b Our research shows that the Vantrue In-Cam is the best model for dashcams. It is very easy to install and has many features that can benefit you throughout your driving experiences. It is highly affordable, and it supports 4K video recording. Moreover, it has a built-in GPS and can record at night because it has an infrared night vision feature. 

Q. How do I get started with a dashcam?

A. The first step in using your dashcam is to mount it on your vehicle’s windshield and plug it into a power source. For most devices, it should be plugged into the cigarette lighter or a USB port for power and connected to the vehicle’s GPS for accurate time and information. Many dash cams, however, come with wireless remote control for powering it up. This is helpful when cold weather prevents you from opening the car door or if you want to turn off recording in areas where you don’t want video footage saved onto the device.
