A rear only dash camera records what happens behind the vehicle through a single lens, and the way it mounts and connects shapes how useful it is. We have not used these products ourselves, so this guide does not rank or promise anything. It shows how to choose, which details deserve attention and which claims to read with care.
Use the guide below to compare cameras made for the back window or rear mirror. Read each maker’s specification sheet, think about your vehicle, and treat the table as a checklist you can carry from one listing to the next. Think about the shape of the rear glass: tint, wipers, a tilted window or a defroster line can all change the view. Check how power reaches the camera, because a long cable has to run along trim from the front of the cabin or from a nearby socket. Also consider whether you want a camera that stands alone or one that pairs with a screen near the driver.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Video quality | Clearer footage shows more detail behind the car. | Check the stated resolution and frame rate. |
| Field of view | A wide angle covers more lanes but adds distortion. | Compare the angle the maker lists. |
| Mount style | A stable mount keeps the view steady. | Check adhesive, suction or clip choices and your window shape. |
| Night video | Low light footage varies a lot between models. | Read sensor notes and look at owner footage. |
| Cable length | The cable must reach the front or a rear power point. | Measure your vehicle and compare with the supplied length. |
| Storage | Loop recording needs a supported memory card. | Check card type, maximum size and file handling. |
Setup and Care Tips
- Clean the glass area with a suitable cleaner before attaching the mount.
- Aim the lens so the road and bumper line are both in the frame.
- Tuck the cable under trim and avoid the pillar areas the maker warns about.
- Format the card as the maker advises and check the clock setting.
- Check local rules on recording and on what may be fixed to the glass.
Mistakes to Avoid
- Choosing a camera without measuring the cable route.
- Placing the lens behind tint that dims the picture.
- Ignoring heat tolerance if the car sits in the sun.
- Letting the camera block the driver’s rear view.
- Using a memory card the maker does not support.
FAQ
Is a rear only camera enough?
It depends on what you want to record. A rear only unit covers events behind the car, while a front unit covers the road ahead. Some people want both and choose a two lens system instead.
Can I mount it on the rear window?
Many models are designed for this, but the glass shape and tint matter. Read the maker’s mounting notes and the rules where you drive before you decide.
The Short Version
Match mounting, cable length and field of view to your vehicle. Compare night video and storage details, and treat each maker claim as something to confirm before you buy.
