What is a dash camera?

A dash camera, or dashboard-mounted camera, is a device that records video footage from the front of a vehicle while it is being driven. These cameras are designed to provide evidence in the event of an accident and can be extremely useful in proving who was at fault.


What are they used for in the UK?

There are a number of reasons why dash cams have become so popular in the UK. Firstly, they can provide evidence in the event of an accident that can help to prove who was at fault. This can be invaluable if you are involved in a hit-and-run or another type of accident where the other driver may not stop.

Secondly, dash cameras can help to protect you from false insurance claims. If you are involved in an accident, the footage from your dash cam can be used to disprove any false claims made against you. This can help to keep your insurance premiums down, as well as protect you from having to pay out for damages that were not your fault.

Dash cams can also be used to monitor your own driving. This can be useful if you are a new driver or want to improve your skills. By reviewing footage of your own driving, you can identify any bad habits and work on improving them.

Finally, dash cameras can provide peace of mind when driving. If you are worried about being involved in an accident, a dash cam can help to put your mind at ease. Knowing that you have footage of an incident can help you to relax and enjoy your journey.

  • Improved safety

How Do Dash Cams Work?

Most dash cams will start recording automatically as soon as you turn on your ignition. They will then continue to record footage of your journey until you turn off your engine. This means that you don’t have to remember to start and stop recording, as the dash cam will do it for you.

The footage from your dash cam is stored on a memory card, which will need to be downloaded periodically. This can be done by connecting the dash cam to your computer using a USB cable. Alternatively, some models come with Wi-Fi connectivity, which allows you to download footage wirelessly.

When choosing a dash cam, it is important to consider the storage capacity of the memory card. Most cards will hold around four hours of footage, although this will vary depending on the resolution that you are recording. If you think that you will need more storage, you can buy a larger memory card.



There are a variety of different dash cameras on the market, including 1, 2, and 3-channel dash cameras. 2 channel dash cams have both a front and rear-facing camera to record the front and rear of your journeys for better footage and enhanced protection on the roads. 3 channel dash cams also have a camera that records the interior of the vehicle, as well as front and rear recordings.
