Trailer Backup Cameras: Five Systems for Easier Hitching and Reversing

Reversing a travel trailer into a narrow campsite with a spotter who has wandered out of sight is stressful for anyone. A trailer backup camera replaces guesswork with a live view of what is behind you, and it can also help you line up the hitch with the ball. The best trailer backup camera for your rig depends on how far the camera is from the monitor, whether you want wired or wireless transmission, and how much night visibility you need.

This guide covers five camera systems by name and gives four checkable buying rules: wired versus wireless, monitor size, mounting and durability, and night vision. As of 2026, digital wireless systems have narrowed the gap with wired setups, though long trailers still pose signal challenges. The reviews stay with what each name tells you, framing pros and cons as category trade-offs.

Quick Picks

How to Choose

Decide on wired or wireless

Wired systems send a signal through a cable, so they rarely drop out, but running cable the length of a trailer takes time. Wireless systems install quickly, but a long trailer or metal body can weaken the signal. A good rule of thumb: for trailers longer than about twenty-five feet, favor a digital wireless system rated for a longer range, or choose wired for reliability. Always check the stated transmission range against your trailer length.

Choose the right monitor size

A screen of around five inches is common for pickup dashboards, while seven or more inches is easier to read for older eyes or in large motorhomes. If the monitor will clamp to the dash or windshield, check that the mount does not block your view. Some systems use the vehicle’s infotainment screen instead; make sure your head unit supports an external video input.

Look at mounting and weather resistance

A trailer camera lives outside, so look for an IP rating of at least IP67 for water and dust resistance. Mount it high on the rear for a wide view of the ground behind, and use a sturdy bracket because vibration can loosen cheap mounts. Check the operating temperature range, especially if you camp in very cold or hot places.

Check night vision and field of view

Infrared LEDs help in the dark but only for short distances. A wide viewing angle, around 120 to 170 degrees, shows more of the surroundings but can distort edges. Consider adding a trailer light or a dedicated reverse lamp if you often hitch at night.

Our Picks Reviewed

Furrion Vision S

Furrion is a brand associated with RV electronics, and Vision S names a system within its range. Pros: an RV-focused brand tends to consider trailer wiring, camera placement, and the realities of long vehicles. A system marketed as an observation setup suits owners who want a live view behind as they drive. Con: specialty RV systems can cost more than generic cameras and may be designed to work as a package, limiting flexibility if you want to mix components. Who should skip it: owners of small utility trailers who need only a basic reversing view, and those who prefer to pick each part separately. It suits owners of larger travel trailers and motorhomes.

Haloview MC7108

Haloview’s MC7108 is a model code for a camera and monitor kit. Pros: a kit approach means monitor and camera are matched, which reduces compatibility questions, and a named model code makes manuals and troubleshooting easier to find. Haloview is a name often seen among RV owners. Con: a kit has a fixed set of components, so you are tied to the supplied monitor size, and wireless connections can drop on longer trailers. Who should skip it: drivers who want to use their built-in infotainment screen, and owners of very long trailers who need a wired signal. It suits trailer owners who want a ready-to-install kit.

Garmin BC 40

Garmin is known for navigation hardware, and BC 40 is a wireless backup camera model. Pros: pairing with compatible Garmin navigators or displays makes sense for drivers already in the Garmin ecosystem, and a well-known electronics brand typically provides support documentation. Con: a camera designed to work with specific displays may not suit a driver who does not own compatible Garmin gear, and wireless range depends on trailer length and construction. Who should skip it: owners without a compatible screen, and long-trailer drivers who need guaranteed signal strength. It suits drivers who already rely on a Garmin device and want to add a rear view without much wiring.

Garmin BC 50

BC 50 sits in the same camera family as the BC 40, and the higher number suggests a later model. Pros: a newer model within an established line may include refinements, and the shared brand ecosystem helps if you already own supported Garmin displays. Con: like its sibling, the camera depends on compatible displays, and wireless performance can vary with trailer size and metal construction. Who should skip it: buyers who want a standalone camera with its own monitor, and anyone who needs a hard-wired connection. It suits owners comfortable with Garmin gear who prefer to integrate a camera into the display they already use.

Auto-Vox W7

Auto-Vox is a brand known for aftermarket backup cameras, and the W7 label indicates a wireless model. Pros: a wireless design typically eases installation because no cable has to run the length of the trailer, which is helpful for renters, part-time towers, and people who swap between trailers. Aftermarket brands often cover many vehicle types. Con: wireless signals may stutter in long rigs or with interference, and the camera mount may need extra care to survive road vibration. Who should skip it: owners of very long trailers who want guaranteed reliability, and those who want a factory-style integrated screen. It suits drivers who tow short to medium trailers and want a simple setup.

Installation and Setup Tips

Plan the camera location before drilling. Mount it high and centered on the rear of the trailer, aimed slightly down so the bumper or hitch edge appears at the bottom of the screen. Keep wiring away from sharp edges and heat sources, and seal entry points with a suitable weatherproof sealant. For wireless units, mount the antenna with a clear line of sight where possible.

Test the system in a parking lot before a trip. Walk behind the trailer and confirm the monitor shows you clearly. Check for ghosting or dropouts while someone drives forward at a slow pace. Adjust brightness for day and night, and turn off any guideline overlays you find distracting. Remember that a camera supplements, not replaces, mirrors and a spotter. Clean the lens regularly, since road film quickly degrades the picture. Finally, consider a power source: some cameras tie into the trailer’s running lights, while others use a separate battery, so factor in maintenance.

Using the Camera Day to Day

Most owners use a trailer camera in two situations: hitching up and reversing into a site. For hitching, aim the camera so you can see the coupler and the ball at the same time, and move the vehicle slowly while watching the screen. For reversing, turn the camera on early so the picture settles before you start moving, and glance at your mirrors as well. A camera gives you information, but you remain the driver.

Learn what the image shows. Wide-angle lenses stretch distances near the edges, so objects look farther away than they really are. Practice in an empty lot with a few cones to learn how the screen relates to the real distance. Add a piece of tape on the monitor as a reference for the trailer’s width if your system does not show guidelines.

Keep the system maintained. Wipe the lens before each trip, check cable connections for corrosion, and charge or replace any batteries well before a long journey. In winter, wet snow can cover the lens, so carry a soft cloth. If the image becomes fuzzy or intermittent, re-pair the wireless link, check the antenna, and test with a shorter distance to rule out interference.

Consider storage too. When the trailer sits in a yard for months, cover the camera or remove it to protect it from sun and weather. A removable monitor stored indoors will last longer, and a quick-mount bracket makes reinstalling it a short job. Note the settings that work best, such as brightness and mirror mode, so setup before each trip takes only a few minutes.

Before buying, measure the distance from the rear of the trailer to the dashboard where the monitor will sit, and add a few feet for routing. Compare that number with the stated wireless range or cable length, and leave a generous margin. Systems that fall short on paper usually fall shorter in practice, because metal walls, slide-outs, and roof air conditioners all weaken the signal.
