Dash cam buyer's guide
Thinking about buying a dash cam but not sure where to start? This dash cam buyer’s guide explains what dash cams do, how they work, key features to look for, and how to choose the best model for your car.
What Is a dash cam?
A dash cam (dashboard camera) is a compact in-car camera that records video footage while you drive. Most dash cams record the road ahead, while others include rear-facing cameras to capture what’s happening behind your vehicle.
Dash cams provide peace of mind by recording evidence that can be used by insurers or police in the event of:
- Road traffic collisions
- Insurance disputes
- Hit-and-run incidents
- Vehicle damage while parked
How do dash cams work?
Dash cams are mounted inside your vehicle, typically on the windscreen. Once powered, they automatically begin recording.
Key functionality:
- Loop recording: Old or unimportant footage is automatically overwritten.
- G-Sensor detection: Sudden impacts trigger automatic clip saving.
- Locked files: Important footage is protected from deletion.
All dash cams sold by Halfords include built-in G-Sensors for collision detection.
Power Options: Plug-In vs Hard-Wired Dash Cams
12V Plug-In Dash Cams
Most dash cams connect via your car’s 12V power outlet and include a cable in the box. Many also feature a small backup battery.
Hard-wired dash cams
Hard wiring connects the camera directly to your vehicle’s fuse box via professional installation.
Benefits of hard wiring:
- Always powered while driving
- Enables advanced parking mode
- Hides cables for a neater install
- Keeps your 12V socket free
Halfords offers professional dash cam fitting to ensure safe, tidy installation.
Where is dash cam footage stored?
Dash cam recordings are stored on a microSD memory card.
You can review footage by:
- Removing the SD card and connecting to a PC or Mac
- Viewing via dash cam apps (Wi-Fi models)
- Transferring clips to smartphones or tablets
Some dash cams include an SD card; others require one to be purchased separately. Always use a compatible, high-quality card to ensure reliable recording.
What is a rear-facing dash cam?
Rear dash cams record footage through your back window.
Setup options:
- Add-on rear camera
- Separate rear dash cam
- Dual-channel (front + rear) systems
Dual systems provide full vehicle coverage and are often considered the best option for insurance protection.
Benefits of having a dash cam
Dash cams offer multiple safety and financial benefits:
- Evidence in accident claims
- Protection against fraudulent claims
- Footage for police investigations
- Recording incidents while parked (parking mode)
They can help prove fault, speeding up insurance decisions and avoiding legal complications.
