Front and rear dash cams

A front and rear dash cam records two views at once: the road ahead through the main camera and the road behind through a second camera at the back of the car. That covers rear-end shunts and incidents behind you that a front camera cannot see. The models here combine both cameras with a large touch screen that also runs Apple CarPlay and Android Auto.

How a two-camera system works

The front unit holds the main camera, the screen and the memory card. The rear camera is a small separate unit with a long cable that runs along the headlining to the back of the car, where it is fixed to the inside of the rear window or near the number plate. Both cameras record to the same card, and the screen can show either picture or both side by side.

Things to check before you buy

  • Cable length. Estates, SUVs and vans need more cable than a hatchback. Measure from the windscreen to the rear window along the roof lining.
  • Rear window. A heavily tinted rear window darkens the rear picture at night. Mounting the camera outside near the number plate avoids this but takes more work.
  • Power. Two cameras and a large screen need a steady supply. The 12V socket works for driving. For recording while parked, read Hardwiring a dash cam or using the 12V socket.
  • Screen placement. A large screen must not block your view of the road. Fit it low on the dashboard, away from airbag covers.

Front and rear or mirror?

A mirror dash cam also records front and rear, but it straps over your rear-view mirror instead of sitting on the dashboard. Our guide Front and rear dash cam or mirror dash cam? compares both.

Frequently asked questions

Where does the rear camera of a dash cam go?

Usually on the inside of the rear window, near the top in the middle, so the rear wiper and the heated wires do not block the picture. Some rear cameras can also be fitted outside near the number plate, which needs a cable through a grommet into the boot.

Can I fit a front and rear dash cam myself?

Yes, most people do. The rear cable is tucked behind the headlining and the trim along the side of the car. Take care around the pillars, because many cars have curtain airbags there. If you are unsure, ask a car audio or accessory fitter.

Does the screen play video while I drive?

It must not be visible to you if it does. Regulation 109 of the Road Vehicles (Construction and Use) Regulations 1986 only allows a screen the driver can see to show things like navigation, vehicle information or a view of the road around the car. Camera views and maps are fine. Films are not.
