1-Minute DIY Installation: what you can expect
If you want a fast swap-in system, you’ll love that the magnetic base and integrated battery mean you don’t drill or hardwire anything. The manufacturer claims a true plug-and-play setup that you can complete in about 60 seconds, and that’s realistic if you’ve got a clean metal mounting spot and the monitor already powered.
Mounting the side cameras (magnetic and angle adjustment)
The magnetic side-view camera has a 180° rotation angle that you can fine-tune by loosening screws under the rubber plate on top of the camera and adjusting the angle. If you need extra help, there’s a video tutorial linked as the seventh image on the product page, or you can reach out to customer service to request it.
Mounting the rear camera
You’ll place the rear camera where you need a fixed rear view — the magnet makes it easy to stick to a trailer frame or metal bumper. Make sure the surface is clean and free of loose paint or heavy rust so the magnet seats solidly and won’t shift while driving.
Powering the monitor and cameras
The monitor can be powered via the included 12V DC vehicle charger or the USB cable for alternative power, offering flexibility when you’re parked or driving. Each camera has a built-in high-capacity battery and comes with a Type-C charger, so you can top up cameras easily between uses or charge all three simultaneously when you’re back at camp.
Monitor and display features
The 7-inch display offers 1080P clarity and supports multiple viewing modes so you can customize the screen layout to match your situation. You can view a single camera full-screen, use split-screen to watch two feeds, or use quad-view if you add a fourth camera later.
Screen quality and daytime performance
You’ll see crisp daytime footage thanks to the full HD monitor and 1080P streaming from the cameras, which makes lane lines, obstacles, and towing connections easy to identify. The brightness and contrast hold up well in direct daylight, although you may need to tweak the monitor settings to match extreme angles and glare.
Night performance and IR night vision
The cameras automatically switch to IR illumination when ambient light drops, so you’ll still get usable images after dark. Expect black-and-white or low-color images at night with decent contrast for identifying larger obstacles and vehicles, which improves reversing and lane awareness in low-light conditions.
Wireless performance and range
This system uses a 2.4GHz dual-antenna wireless link designed for lag-free transmission, and the manufacturer states an open-range coverage of up to 330 feet with reliable signal at highway speeds. That makes it very suitable for trailers, larger RV setups, and commercial trucks that need long-range connections.
Interference and reliability tips
You’ll want to be mindful of sources of 2.4GHz interference like Wi-Fi hotspots, certain radios, or other wireless devices; placing the monitor and antenna to minimize obstructions will help. For best results, keep the monitor antenna oriented toward the cameras, and avoid placing cameras directly behind thick metal panels that could attenuate the signal.
Video recording and instant playback (DVR)
The monitor supports loop recording so you can continuously capture driving footage; this creates a rolling log that’s useful for evidence and review. To use DVR features, you’ll need to insert an SD card (up to 128GB), and once installed you can access recordings directly from the monitor.
How to set up the SD card and access playback
You’ll insert an SD card into the monitor’s slot, format it via the monitor menu if requested, and enable loop recording or event recording as needed. Playback is straightforward: use the monitor controls to browse files and play back clips without removing the card, which is convenient when you want to review footage on the spot.
Battery life, charging habits, and power management
Each camera contains a high-capacity rechargeable battery designed for portable use, and the kit includes three Type-C chargers so you can rotate charging when you’re off the road. Battery life will vary significantly depending on recording habits, whether IR night vision is active, and how frequently you stream live to the monitor, so plan for shorter runtimes with continuous recording.
Practical charging strategies
You’ll get the most out of battery life by charging cameras after a trip and switching to an efficient recording mode when you need long standby times. If you plan to use the system for extended trips, consider a small portable power bank or a hardwired 12V solution to keep older cameras topped off without interrupting your monitoring.
Durability, weather resistance, and IP69 rating
IP69K is one of the most robust ingress protection ratings, meaning the cameras are built to withstand high-pressure, high-temperature washdowns and heavy exposure to water and dust. This rating makes the system suitable for rugged use on marine equipment, heavy trucks, and trailers that get regular hosedown cleaning.
Real-world durability considerations
You’ll still want to avoid hitting cameras with impacts or scraping them against hard surfaces, as the magnet makes quick remounting easy but doesn’t protect against mechanical knocks. For saltwater or highly corrosive environments, rinse and maintain metal mounting points to keep magnets and screws working reliably.
Image orientation and dynamic parking assist
You’ll be able to toggle mirror/flip settings on the monitor to align images depending on where you mount the cameras, which is useful for side or angled installations. The dynamic parking assist lines are a welcome aid for hitching trailers and parking tight rigs, as they give you visual guidance that adapts when you change mounting angles.
Adjusting camera angle and rotation
To achieve the optimal side-view angle, loosen the small screws under the rubber plate and rotate the camera until you get the right sightline, then retighten securely. This 180° rotation capability gives you flexibility when mounting on different vehicle profiles and makes repositioning straightforward when you transfer cameras between vehicles.
Multi-camera management and expandability
The system supports up to four cameras simultaneously, so you can add another view if you want a dedicated cabin, front, or additional side camera. You’ll manage camera feeds from the monitor menu and choose display modes that give you the best situational awareness for your current task.
Using split-screen and quad-view modes
You’ll find split-screen helpful when you need to monitor both sides while towing, and quad-view makes sense when you want a full surround view during complex maneuvers. Just remember that viewing multiple feeds divides the screen, so fine detail is easier to read on full-screen mode or with the 1080P clarity.

Tips and tricks to get the best results
These practical suggestions will help you keep the system running reliably and get clearer images and stronger signals. Following a few simple habits will extend battery life, prevent footwork during installation, and make recordings more useful.
- Clean metal mounting surfaces before attaching cameras to ensure a tight magnetic grip. This prevents slipping during motion and reduces the risk of losing a camera on rough roads.
- Position the monitor antenna for a clear line-of-sight to the cameras where possible, and minimize large metal obstructions between monitor and camera. This reduces interference and keeps your feed stable.
- Charge cameras after each long trip and store them with a partial charge if you won’t use them for an extended period. Batteries last longer when stored at around 40–60% charge in cool, dry conditions.
- Use loop recording and set a reasonable segment length on the monitor so you can locate events quickly without managing dozens of tiny files. Formatting the SD card from the monitor menu before initial use helps system compatibility.
- If you need continuous recording for longer durations, consider using a power bank adapter or a small 12V hardwire solution to provide steady power during operation without draining camera batteries.
Common issues and troubleshooting
A few typical problems may appear in real-world use, but most are solvable with simple fixes you can do yourself. Identifying the symptom quickly helps you get back to safe driving faster.
Weak signal or dropped feed
If your feed drops, first check antenna orientation and move the monitor to minimize obstructions between it and the cameras. If that doesn’t help, bring cameras closer to the monitor and re-test; magnets and mounting positions can sometimes create unexpected signal blockages.
Cameras won’t pair or show up on the monitor
Ensure cameras are fully charged and powered on, then power cycle the monitor to allow it to rediscover cameras. If pairing still fails, consult the manual for the monitor’s pairing sequence and contact customer support if you need the tutorial video referenced in the product images.
Poor night image quality
Night mode uses IR illumination, which reduces color and detail but improves contrast; cleaning the camera lens and ensuring the camera isn’t pointed at reflective surfaces will help. Reducing IR reflections from nearby lights and adjusting monitor contrast can also yield better night visibility.
Magnetic mount slips or shifts
If the magnet seems weak, clean both the magnet and the metal surface and then remount. If the surface paint or corrosion decreases magnetic grip, consider adding a small metal plate behind the camera (securely attached) to create a flat, ferrous mounting pad.
Resetting and re-pairing cameras
Resetting typically involves power-cycling the camera and monitor, placing the camera near the monitor for initial pairing, and following on-screen prompts. If you can’t locate the monitor pairing menu, contact support to request the tutorial video that shows this setup step-by-step.
