Applications & Target Vehicles:

Versatile Digital Wireless Deployments: From Highway Logistics to Farm Fields

  • Agricultural Slurry Spreaders & Fertilizers: The perfect zero-cable safety solution for wide-chassis slurry tankers and muck spreaders. The robust digital wireless transmission effortlessly penetrates heavy steel tanks, providing the tractor operator with a clear, real-time rear view to monitor spreading width and prevent backing collisions with fences or gateposts.

  • Farm Tractors & Agricultural Trailers: Eliminates the hassle of running long, complex video cables across the trailer hitch. Whether hauling grain, livestock, or silage, the camera mounts securely to the rear of the trailer, sending an instantaneous 1080P feed directly to the in-cab monitor without signaling degradation during tight vehicle articulation.

  • Commercial Freight & Semi-Trailers: Streamlines fleet operations for logistics companies using interchangeable trailers. Since the transmission is entirely digital wireless, any tractor unit can instantly pair with any equipped trailer, significantly reducing vehicle coupling time and eliminating wear-and-tear on physical aviation connectors.

  • Livestock Transport & Horseboxes: Provides farmers and transport operators with uninterrupted real-time surveillance of the rear perimeter or internal livestock bays, ensuring animal safety and precise maneuvering on unpaved, high-vibration rural roads.

  • On-Site Construction Dump Trucks: Built to withstand severe terrain shocks and dust clouds. The integrated DVR recording functions as an essential accountability tool, capturing continuous footage of loading, transit, and dumping operations for fleet safety compliance

 

Frequently Asked Questions: 

Q: Does "Quad Split" mean I have to see all 4 cameras at once?

A: Not necessarily. You can choose to see one camera full-screen, two in split-view, or all four at once. It’s completely flexible depending on whether you’re cruising or parking.

Q: Will the signal hold up with four cameras running?

A: Yes. We use a high-bandwidth digital frequency that handles all four feeds without lag or screen jumping, even when you’re passing other heavy vehicles on the motorway.

Q: How much "faff" is the installation really?

A: Very little compared to a wired system. You just need to power the cameras and the monitor. You’ll save hours of work by not having to run video cables through the chassis or under the carpets.

Q: Does it support DVR recording?

A: Yes. DVR recording is available as an optional function for customers who need video storage and playback.
