It is certainly possible to tell vehicle speed from a dashcam video, but there are a few things to keep in mind.
The accuracy of the measurement will depend on the quality of the video and the capabilities of the dashcam itself.
For example, if the video is low quality or blurred, it will be more difficult to accurately measure speed.
Additionally, some dashcams include GPS functionality which can be used to more accurately determine speed.
There are a few different methods that can be used to measure speed from a dashcam video. One common method is to use software that can track objects in a video and then measure their speed based on their movement across the frame.
This can be reasonably accurate, but again, it depends on the quality of the video and the capabilities of the software.
Another approach is to use optical flow algorithms, which track objects in a video by analyzing their movement across multiple frames.
This method can be quite accurate, especially if there are clear reference points in the video like road markings or traffic signs.
Ultimately, whether you can accurately measure vehicle speed from a dashcam depends on your particular setup and what you need to achieve with your measurements.
If you are interested in using a dash cam to measure vehicle speed, there are several things to consider.
First, it is important to choose a high-quality dash cam that can capture clear and detailed images of your surroundings. This will help ensure that you get accurate measurements, regardless of what software or algorithms you use.
You should also consider the capabilities of any software or other tools that you might be used to analyze your video.
Some options may be better suited for measuring speed than others, so it is important to do your research ahead of time and find a solution that works well for your needs.
Ultimately, though, with the right setup and tools, it is possible to accurately measure vehicle speed from a dashcam video.
So if this is something you are interested in, do your research and find a solution that works for you!
Do Police Dashcams Show Speed?
Yes. Police dash cams show speed, as well as the driver’s face, the car’s license plate, and the road in front of the car.
Dashcams vary in quality and some may not be able to capture the speed of a car. However, typically, if the dashcam is in clear view of the car’s speedometer, it will show the speed.

How Do Dash Cams Measure Speed?
Dashcams measure speed using a variety of methods, typically either GPS or VSS (vehicle speed sensor).
GPS is most common because it is relatively cheap and accurate.
VSS is less common, but it can be more accurate because it measures wheel speeds rather than ground speed. This is important for accuracy in cases where the vehicle is going around a curve.
