Overview
A battery powered, magnetic mount backup camera that streams over WiFi straight to an iPhone or Android app rather than a dedicated monitor, built for hitching up trailers, boats and horse trailers without running any wire.
The magnetic mount is the core idea: EWAY describes it as patent protected and built to hold onto flat metal surfaces on hitches, tongues and bumpers through the vibration of towing, so the camera can be moved between a truck, a horse trailer and farm equipment rather than staying fixed to one vehicle. It runs on a rechargeable battery over Type-C, rated for 8 hours between charges, with 12V hardwiring as the alternative for a permanent setup.
- Magnetic mount for hitches, tongues and bumpers
- WiFi streaming to iOS 12+ / Android 7+ phones
- IP68 waterproof, submersible to 1.5m for 30 minutes
- Type-C rechargeable (8hr) or 12V hardwire option
Who it's for
Anyone hitching up trailers, boats or horse trailers solo who wants a camera view on their phone at the hitch or tongue without wiring a screen into the cab. It suits farm and ranch use where the same camera might move between different equipment.
Pros and cons
- Magnetic mount moves between hitches, trailers and equipment
- No wiring needed, runs on battery over WiFi
- IP68 rated, submersible to 1.5m for 30 minutes
- 9 infrared LEDs for low light hitching
- Needs stable WiFi and close range (about 30 ft) to the phone
- Battery needs an 8 hour initial charge and cannot use a quick charger
Performance notes
Because the video runs over the phone's own WiFi rather than a dedicated receiver, iPhone users need Local Network access enabled for the app and a VPN turned off to keep the connection stable, and EWAY specifies staying within 30 feet of the camera. On the power side, the battery needs an 8 hour initial charge with the camera switched off, and EWAY is explicit that a quick charger will damage the unit and that the DC port is for permanent power only, never for charging.
