What is a dash cam?
A dash cam (short for dashboard camera) is a small video camera that mounts to your vehicle’s windscreen or dashboard and continuously records your journey.
Most dash cams automatically begin recording when you start the engine, capturing footage of the road ahead. Some models also include rear-facing cameras or interior cameras for additional coverage.
Most modern dash cams include:
- Loop recording
- High-definition video
- Automatic incident detection (G-Sensor)
- Parking mode
- GPS tracking
- Wi-Fi connectivity
- Smartphone app support
If the memory card becomes full, loop recording automatically overwrites the oldest footage, ensuring continuous recording.
How does a dash cam work?
Once installed, a dash cam is powered through your vehicle’s USB port, 12V socket or hardwired power supply.
As you drive, it records video in short clips that are stored on a memory card.
Many models include a built-in G-Sensor, which automatically detects sudden impacts or heavy braking. When this happens, the current footage is locked so it cannot be overwritten.
Some dash cams also offer:
- Rear cameras
- Interior cameras
- Night vision
- Voice control
- Emergency SOS features
- Cloud storage
Are dash cams legal in the UK?
Yes.
Dash cams are perfectly legal in the UK provided they:
- Do not obstruct the driver’s view.
- Are securely mounted.
- Do not interfere with airbags or vehicle controls.
If your dash cam records audio, remember that privacy rules may apply depending on how the footage is used.
Why should you buy a dash cam?
There are several reasons why many UK drivers choose to install a dash cam.
Evidence after an accident
Dash cam footage can provide valuable evidence following a collision.
Rather than relying on conflicting witness statements, video footage can help establish exactly what happened.
If you should ever be involved in an accident, and you’re unsure on what to do, we’ve covered what to do after an accident.
Protection against insurance fraud
Dash cams can help protect drivers from fraudulent insurance claims, including staged accidents and “crash-for-cash” scams.
Video evidence can make it easier for insurers to determine liability.
Encourages safer driving
Knowing that your driving is being recorded often encourages more careful driving habits.
Many professional drivers and fleet operators use dash cams for this reason.
Parking protection
Many premium dash cams include Parking Mode.
If another vehicle hits your parked car or someone attempts to damage it, the camera can begin recording automatically.
Faster insurance claims
Providing clear video evidence may help insurers investigate claims more quickly, potentially reducing disputes.
Can a dash cam reduce your insurance premium?
Possibly—but not always.
Some insurers may take the use of a dash cam into account when calculating your premium, particularly if it helps reduce the likelihood of disputed claims.
However, there is no guarantee that installing a dash cam will reduce your insurance costs.
Even if your premium doesn’t change, the footage can still prove invaluable following an accident.
If you’re unsure on when and when not to make an insurance claim, we’ve covered all you need to know, should you ever be in that position where you need to make a claim.
