ST-799WRS-4 | Professional Quad-Split Wireless Kit for HGVs & Campervans

Let’s be honest—wiring a 12-metre lorry or a tidy campervan is a job nobody wants. You need to see your blind spots, but you can’t afford to waste a whole day stripping the cab and running cables through a greasy chassis. This 7-inch Quad-Split system was built to fix exactly that.

This isn't some flimsy gadget; it’s a proper, heavy-duty bit of kit. Whether you’re navigating tight city streets in a rigid truck or squeezing into a narrow pitch in your camper, you can see all four corners of the vehicle on one screen. The digital link is rock-solid—it won’t flicker or drop out when you pass other lorries on the motorway. Plus, with the built-in DVR recording all four angles, you’ve got the footage ready if a "cash-for-crash" scammer comes your way. It’s a no-nonsense tool that lets you see what you're doing without the faff of a complicated install.

Why This Kit Makes Sense for Your Fleet:

• 360° Visibility on One Screen The Quad Split monitor allows you to view up to four cameras at once. You can cover your rear, both side blind spots, and even the front—giving you total visibility when navigating tight city streets or busy loading bays. 

• Rock-Solid Link for Long Lorries No more flickering or signal drops. The encrypted digital connection stays steady even on 12-metre lorries, and it won’t pick up interference from other trucks or devices when you’re on the motorway.

• No Faffing with Cables Perfect for Campervans and high-spec cabs. Since it’s wireless, you don’t have to rip up the tidy interior or drill through the dash to run metres of video cable. It’s a clean, fast install that gets you back on the road in no time.

• 4-Channel Evidence for Insurance The built-in DVR records all four channels in 1080P to an SD card. In the event of a "cash-for-crash" scam or a side-swipe, you’ve got the HD footage ready to protect your insurance premium and your license.

Suitable Vehicle Types:

3. Delivery Vans & LWB Vehicles Essential for couriers navigating city centres. Being able to see both sides and the rear at the same time drastically reduces minor scrapes in tight car parks.

Frequently Asked Questions: 7" Digital Wireless DVR Monitoring System

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: Is the recording quality good enough for insurance?

A: Absolutely. It records in 1080P HD. If you’re involved in an incident, the footage is clear enough to show number plates and exactly who was at fault, which is vital for protecting your "no claims" discount.
