Using this device has been surprisingly simple. The setup connects quickly over Wi-Fi, which is convenient, although you do need to dedicate a mobile device since it uses your phone's connection—just something to keep in mind if you rely on cellular data constantly while using it. The magnetic attachment is incredibly strong; I was worried it might shift while driving, but other buyers seem to feel similarly—the magnet really locks down and doesn't budge, even on the highway.
I've been getting a really good range, about 7 to 8 meters, which is more than enough for my setup, and the image quality is sharp and beautiful during the day. It’s working perfectly as a dedicated closed van or trailer mirror helper.
One area where I haven't fully tested it yet is deep darkness, but based on its performance during overcast days, I’m optimistic about the night vision capability. A small note, though: the charging port protector seems a bit flimsy, so I'm being extra careful with that piece. The operating time seems solid too; I got about 6 hours of continuous use before needing a top-up.
Overall, if you have a trailer, RV, or truck where a magnetic attachment works well (and not aluminum or fiberglass structures where magnets struggle, as one user noted), this product is fantastic.
I highly recommend the GreenYi 5G WiFi Magnetic Hitch Wireless Rear View Camera for anyone needing an easy, robust backup solution. It’s one of those gadgets you buy and instantly wonder how you managed without it. If ease of installation and reliable magnetic mounting are priorities for you, definitely grab this wireless camera.
