In this comprehensive review, we’ll take a deep dive into the Solar3A Plus: how it works, its core features, installation experience, and why it might be the best backup camera for your vehicle in 2025.

What Is the Solar3A Plus?

The Solar3A Plus is a 1080P wireless backup camera system designed and manufactured by AUTO-VOX, a trusted name in automotive safety technology. It's specially engineered for users who need both power and portability—whether you're commuting through the city or off-roading in a trailer or RV.

Unlike traditional hardwired backup cameras, the Solar3A Plus is entirely wireless and features a solar-rechargeable battery, advanced night vision, dual-channel support, and IP69K waterproof durability. With a quick, drill-free installation and an easy-to-read 5" split-screen monitor, this camera is built for drivers who want high-quality visibility without the technical hassle.

Who Is It For?

• RV and trailer owners who need a wide-angle, dual-camera view for safe reversing and monitoring blind spots.

• Outdoor adventurers who camp, travel, or tow frequently and need a durable camera that can handle changing environments.

• Daily drivers seeking an easier way to park, reverse, or back into tight urban spaces safely.

• DIYers who prefer an easy, no-wire installation over complicated setups.

If you fit any of these profiles, the Solar3A Plus could be the perfect match for your vehicle safety needs.

Key Features Overview

Let’s explore the core features that make this camera system stand out:

1. True Wireless with Solar Power Support

The Solar3A Plus is powered by a 5000mAh battery that lasts up to 3–4 months on a single USB charge. What sets it apart is the built-in solar panel, which continuously tops off the battery during daylight. This hybrid power setup ensures long-term reliability while promoting eco-friendly, low-maintenance use.

2. 1080P HD Image Quality

Clarity matters when you’re reversing in tight spaces or monitoring trailers. The Solar3A Plus offers full 1080P resolution with crisp, real-time video that helps you see what’s behind your vehicle—day or night.

3. Split-Screen Dual Camera Support

Add a second camera (sold separately) to monitor both front and rear views or left/right blind spots. The 5-inch monitor can display a single or split-screen view, allowing flexible setups for complex driving scenarios.

4. Wide-Angle Vision

Equipped with a 140° field of view, the camera captures a broad perspective behind your vehicle, helping reduce blind spots and making it easier to park, back up, or hook up a trailer.

5. Night Vision Clarity

With upgraded infrared sensors, the Solar3A Plus offers clear visibility in total darkness. Whether you’re reversing into a campsite at night or maneuvering through poorly lit streets, you’ll see what matters most.

6. Stable Signal Transmission

Thanks to advanced frequency-hopping technology, this system maintains a strong and lag-free signal up to 52 feet—making it ideal for both small vehicles and large RVs or trailers.

7. Weather-Resistant and Rugged

Built to withstand extreme temperatures (from -4°F to 149°F) and IP69K waterproof rated, the camera is protected against rain, snow, dust, and high-pressure washing. It's a true all-weather solution.

8. Quick DIY Installation

The Solar3A Plus is designed for tool-free installation in under 2 minutes. It includes anti-theft screws and mounts that can be secured with just a screwdriver—no drilling, wiring, or professional help needed.

Performance in Real-World Scenarios

A. RV and Trailer Use

Many RV and trailer owners struggle with rear visibility. The Solar3A Plus eliminates guesswork with real-time HD imaging, a wide viewing angle, and stable wireless transmission—even at long distances. Users report the ability to back into campsites, monitor trailer attachments, and improve safety while on the road.

B. Urban Parking

Parallel parking in tight urban environments can be a hassle, especially for SUVs or pickups. With the six selectable parking guidelines and the flexibility to flip the image for mirror or normal view, the Solar3A Plus offers reliable assistance in any direction.

C. Towing and Hitching

One of the biggest challenges for truck owners is aligning a hitch. With the camera installed at the rear and real-time visuals on the monitor, hitching a trailer becomes a solo operation with no back-and-forth required.
