Overview
Sticking a strong magnet to a trailer or truck holds this camera in place, and it sends its picture over WiFi to an iPhone or Android phone. A rechargeable battery means no wiring is needed.
Hitching up a gooseneck or horse trailer gets easier with a live view of the coupler, and the phone serves as the screen. The limitation is the wireless link, which depends on the phone connection and the battery charge.
Who it's for
A gooseneck, boat or horse trailer owner hitching alone benefits from a clear view of the coupler. Drivers who want a permanent rear camera on a dashboard monitor should look at a wired kit.
Pros and cons
- Strong magnet mount
- No wiring needed
- Wide angle view
- Streams to phone or tablet
- No monitor included
- Battery needs recharging
- Video resolution is modest
- Range not listed
Performance notes
The camera creates its own WiFi link to the phone, so the picture depends on signal strength and the battery level. A wide lens shows a large area around the coupler, but only at modest resolution. Mounting on clean flat metal stops the magnet from shifting.
