Auto-Vox Solar 3A Plus Review: Drill-Free Reversing Camera

A reversing camera acts as a digital shoulder check, revealing obstacles in the blind spot before they become dents. The Auto-Vox Solar 3A Plus is simple to fit and convinces with good video quality and sensible extras.

Parking in tight spaces tests anyone's patience, and while newer cars carry built-in reversing cameras, older vehicles benefit enormously from retrofitting. The Solar 3A Plus makes that astonishingly painless: it works wirelessly and on solar power, so the bodywork never meets a drill. Comfort does not come simpler.

Video lands on a 5-inch monitor at 1920 x 1080 pixels. The waterproof camera covers a 140-degree field of view and tilts 35 degrees up or down. Because it carries a battery topped up by an integrated solar panel, the camera unit is admittedly bulky — battery and panel need their space. The 5,000mAh battery wants a full charge over micro-USB before first use (allow five to six hours). How long it then runs autonomously depends on usage and sunshine: Auto-Vox quotes up to around 110 days, while dark winters may demand a top-up via the 1.5-metre USB cable every few weeks; continuous operation manages up to twelve hours.

Camera and battery bolt to a sturdy metal plate, removable if the garage lacks a charging option. The plate sticks behind the number plate with supplied double-sided tape, above or below it — both work, since the monitor can mirror the image. The monitor itself feels premium despite a glossy display, hooks into a foot with a ball joint for free rotation and tilt, and sticks to the dashboard with an adhesive pad rather than a suction cup, ensuring an ideal angle towards the driver. Power comes from the cigarette lighter via a generous 3.5-metre cable, and the adapter's spare USB port keeps another device charged.

There is no setup to speak of. The camera switches on via a side button, the monitor wakes automatically with the ignition, and the wireless link establishes itself in moments — flawless and stable in the test, with the manufacturer quoting up to 16 metres of range. Three side buttons adjust brightness, contrast and image mirroring, and parking guide lines can be shown and adjusted for width. A particular party trick: the monitor pairs with two cameras simultaneously and shows both in split screen — front and rear at once, for instance.

The video quality earns real satisfaction: enormously clear and sharp, contrasty, colour-true and vivid, with barely an artefact in daylight and commendable depth and detail. After dark, a street lamp suffices for satisfying results; the edges darken and artefacts appear, but the camera remains a sound orientation aid. With the lens properly aligned you see precisely what hides in the blind spot — another parked car, playing children, a bollard — and parking itself becomes markedly easier once you have internalised the distances the guide lines represent.

The Auto-Vox Solar 3A Plus is a convincing retrofit reversing camera: drill-free solar-powered installation, a stable wireless link, strong 1080p picture quality and clever extras like dual-camera split screen. The bulky camera unit is the honest price of its self-sufficiency — a fair trade for any older car gaining a modern safety net.
