Best Rear Dash Cams (Researched and Compared)

1. Vantrue N4 Rear Module: Best Overall

🛒  Check Price on Amazon →

The Vantrue N4 rear module is built to slot into an existing Vantrue front recorder, turning a single-channel setup into a rear-watching system. Its 1080p sensor keeps plates and headlights readable even when a tailgater is right on your bumper.

Because it is an add-on rather than a standalone camera, you run one slim cable from the front unit to the back glass. That keeps the install tidy while giving you a clear record of anything approaching from behind.

• Add-on rear module that pairs with a compatible Vantrue front unit for full coverage
• Sharp 1080p footage holds plate detail from cars sitting behind you
• Compact body mounts cleanly to the rear window glass

Pros: Excellent low-light clarity for night tailgater situations; Reliable single-cable connection to the front recorder; Backed by a well-supported camera ecosystem
Cons: Needs a compatible Vantrue front unit to function

2. VIOFO A129 Rear Camera: Best Value

The VIOFO A129 rear camera is a popular add-on that attaches to a matching VIOFO front recorder and points out the back of the cabin. It delivers consistent 1080p footage that captures the vehicles behind you on the highway and in stop-and-go traffic.

Routing is straightforward with the included cable, and the bracket sticks neatly to the rear glass. It is a sensible choice if you already own or plan to buy a VIOFO front camera.

• Pairs with VIOFO A129 and compatible front cameras as the rear channel
• Steady 1080p capture aimed straight out the back window
• Simple rear-glass mount with an adhesive bracket

Pros: Strong image quality for the value; Widely supported within the VIOFO lineup; Discreet footprint behind the rear glass
Cons: Requires a compatible VIOFO front unit to record

3. WOLFBOX Rear Add-On Camera: Best Add-On Module

🛒  Check Price on Amazon →

The WOLFBOX rear add-on is meant to complete a WOLFBOX front setup by adding a dedicated rear channel. Its 1080p sensor is tuned to capture the cars tailgating you and to document any rear-end contact clearly.

You can mount it on the rear window glass for a clean cabin install or position it near the bumper for a lower, closer angle. Either way it ties back to the front recorder over a single run of cable.

• Designed as a rear channel for compatible WOLFBOX front mirrors and units
• 1080p rear sensor focused on tailgater and rear-end protection
• Flexible mounting on the rear window or near the bumper

Pros: Easy pairing with the WOLFBOX front ecosystem; Wide rear field of view; Weather-resistant build for exterior mounting
Cons: Only works with a compatible WOLFBOX front unit

4. Rexing M2 Rear Camera: Best for Mirror Setups

🛒  Check Price on Amazon →

The Rexing M2 rear camera serves as the back-facing half of the Rexing M2 mirror system, feeding rear video to the mirror display and recorder. The 1080p sensor keeps the traffic behind you in focus during day and night driving.

The included cable is long enough to reach from the mirror at the front to the rear glass, and the bracket holds the camera steady against the window. It is a natural pick for drivers running the M2 mirror up front.

• Rear channel for the Rexing M2 mirror-style front system
• 1080p footage covering the lane and traffic behind you
• Rear-glass mount with a long included cable run

Pros: Clean integration with the M2 mirror display; Long cable simplifies front-to-back routing; Solid daytime and nighttime rear clarity
Cons: Tied to the Rexing M2 front mirror unit

5. AUTO-VOX Rear Camera: Best for Bumper Mounting

🛒  Check Price on Amazon →

The AUTO-VOX rear camera is built for drivers who want the rear lens mounted low on the bumper or by the license plate rather than on the cabin glass. Its weatherproof housing stands up to rain and road grime in that exposed position.

Mounted at bumper height it gives a close, ground-level view that is ideal for documenting rear-end taps and tight parking situations. The exterior placement adds a little wiring work but rewards you with a tighter rear angle.

• Rugged rear camera suited to bumper or license-plate mounting
• Weatherproof housing for exterior installation
• Pairs with compatible AUTO-VOX front and mirror systems

Pros: Durable design built for outdoor mounting; Close, low rear angle great for parking and bumper contact; Good wide-angle rear coverage
Cons: Exterior cable routing takes more install effort

6. Pelsee Rear Camera: Best Wide-Angle Rear

🛒  Check Price on Amazon →

The Pelsee rear camera adds a wide-angle rear channel to a Pelsee mirror or front system, widening how much of the road behind you gets recorded. The 1080p lens pulls in the cars in your lane and those in the lanes beside you.

It mounts to the rear glass and connects back to the front display over the supplied cable. The extra width is handy for catching tailgaters who drift between lanes before closing in.

• Rear channel for Pelsee mirror-style and front systems
• Wide-angle 1080p lens covering multiple lanes behind you
• Rear-glass mounting with a guided cable path

Pros: Broad rear field of view catches adjacent lanes; Smooth integration with Pelsee mirror displays; Clear nighttime rendering of headlights and plates
Cons: Depends on a compatible Pelsee front unit

7. Nextbase Rear View Module: Best for Modular Systems

🛒  Check Price on Amazon →

The Nextbase Rear View Module clips directly onto a compatible Nextbase front camera, adding a rear-facing channel without a separate unit on the back glass. That modular design makes it one of the easiest rear options to fit.

It records the traffic behind you in 1080p straight through the cabin, which keeps the install clean. Because it shoots from up front, its rear reach depends on a clear view through the back window.

• Clip-in rear module for compatible Nextbase front cameras
• Captures rear traffic with 1080p clarity
• Tool-free attachment to the Nextbase front body

Pros: Very simple modular install with no extra long cable; Tidy footprint with no separate rear-glass unit on some setups; Backed by the established Nextbase platform
Cons: Cabin-mounted angle limits how far back it sees through the rear glass

Frequently Asked Questions

Do rear dash cams need a compatible front unit?

Many rear dash cams are add-on modules rather than standalone cameras, so they only record when paired with a compatible front unit from the same brand. Standalone rear-only cameras exist too, but if you are buying an add-on module, confirm it matches your front recorder before purchase.

Should I mount the rear camera on the window or the bumper?

Rear-window mounting is the easiest and keeps the camera protected inside the cabin, though tint and glass can slightly affect clarity. Bumper or license-plate mounting gives a lower, closer angle that is better for documenting rear-end contact and parking, but it needs weatherproof hardware and more involved cable routing.

How hard is the cable run to the back of the car?

Running the cable from a front recorder to a rear camera usually means tucking it along the headliner and down a rear pillar, which most owners can do in under an hour. Add-on modules that clip onto the front unit avoid a long run entirely, making them the simplest option for a rear channel.
