A dash cam is a small forward-facing camera which records video from behind your windscreen. If you're involved in an accident the saved footage can be used as evidence for insurance claims and - if necessary - in court.
How do dash cams work?
Dash cams plug into the 12 volt socket in a car to power it and record on a constant loop when the engine is running. All require a MicroSD card to store the footage (although this is rarely included when you buy a dash cam) and typically a 32GB card can store around four hours of footage.
When the memory card becomes full, the camera starts recording over the earliest footage. However, cleverly, sensors inside even cheap dash cams can sense when there’s been a change in G-Force which could signify an accident. In this case, many record around 10 seconds before and 20 seconds after the change and store it in a separate folder to ensure it is overwritten and deleted.

In some cases you can save up to 20% on your car insurance, but it depends which insurer and dash cam you use as not all insurance companies offer a discount. If they do, you’ll need to have the camera permanently fitted in the car and powered by your fusebox.
