Grote pushes rear-view camera video through standard seven-way plug
New 4See camera uses existing J560 harness to carry tens of megabits per second, eliminating wireless pairing and extra cables.
Grote Industries launched a rear-view camera that sends video through the standard seven-way connector already on every trailer, eliminating the wireless pairing or extra cable runs that backing cameras typically require.
How does the Grote 4See camera send video through a seven-way connector?
The camera uses new data-transfer technology to push tens of megabits per second through the existing J560 harness, according to Adam Slade, who demonstrated the system at the American Trucking Associations' 2026 Management Conference & Exhibition. That bandwidth is enough for multiple camera feeds plus tire-pressure and lighting-condition data from other trailer sensors.
"With great transfer speed, ample bandwidth for multiple cameras, and soon to include the addition of bi-directional truck-trailer data, this technology eliminates the need for a new tractor-trailer connector," said Andrew Grose, vice president of Grote Networks.
The camera expands Grote's 4See smart trailer platform, introduced in 2022. That system uses a digital wiring harness to connect trailer devices and bring information from otherwise separate systems together, including lighting, tire monitoring, and cargo sensors.
What trailers can use the new camera?
Grote says the camera can be added to trailers already equipped with 4See. Fleets that installed the 4See platform in 2022 or later can retrofit the camera without replacing the digital harness.
For trailers without 4See, adding the camera means installing the full 4See digital wiring system first. Grote has not published retrofit pricing for either scenario.
What this means for backing-camera installations
Most backing cameras on the market today require either a wireless connection between the camera and the in-cab display, or a dedicated video cable run alongside the seven-way. Wireless systems add pairing steps to the pre-trip and can drop signal in high-interference yards. Dedicated cables add another connection point to check when a camera stops working.
Pushing video through the seven-way removes both failure modes. The camera powers up and transmits as soon as the trailer plugs in. No pairing. No second cable to route, protect from road debris, or replace when a driver runs over it during a tight back.
The trade-off is lock-in to Grote's 4See ecosystem. A fleet running mixed trailer brands would need 4See harnesses on every trailer to standardize on this camera, or run two different backing-camera systems.
Grote has not said when the camera will ship or what it will cost per unit. Fleets interested in the system should ask whether the camera works with non-Grote tractors and displays, or whether it requires a Grote-supplied in-cab monitor.
