A Visionworks HD monitor shows and records up to four cameras, but most kits come with one camera (the horse trailer interior and exterior system comes with two). The other three slots are where a backup camera becomes a full view around the rig: down both sides when you change lanes, at the hitch, or inside a horse trailer. We stock seven Visionworks add-on wireless cameras (eight part numbers, counting the side marker pair). This guide shows where each one goes, how it mounts and which combinations make sense.
The rule that comes first: stay in the HD line
Every add-on camera below pairs with any Visionworks HD wireless monitor. That covers the monitors in the Gen2 RV kits, the magnet-camera systems, the rear indicator light and horse trailer systems, and the standalone 5", 7" and 10" touchscreen monitors. The HD parts end in -HDWL (the Gen2 RV kits end in -HDWLRV, and the horse trailer interior and exterior system is VWIC714-HTV2WL).
One warning from Visionworks: the long-range VWCAMAIO1-HDWL camera doesn't work with its MACH2 systems or any non-HD monitor. If you have an older Visionworks monitor, check its part number before you add a camera. If you're not sure what you have, send us the part number.
The add-on cameras
| Camera | Part number | Where it goes | Good for |
|---|---|---|---|
| Gen2 RV camera | VWCAMG21-HDWL | The rear camera position on RVs pre-wired for a Furrion camera | Replacing a rear camera, or adding the Gen2 camera to a monitor you already own |
| Side marker light camera, left | VWCAMSML1-HDWL | A side marker light position, driver side | The driver-side blind spot on the road and when parking |
| Side marker light camera, right | VWCAMSMR1-HDWL | A side marker light position, passenger side | The passenger-side blind spot, the harder one to see in a mirror |
| Side marker light cameras, pair | VWCAMSMP1-HDWL | Both sides | Both blind spots, bought together |
| License plate camera | VWLCAM1-HDWL | Mounted with a license plate | An easy rear view on a trailer or tow vehicle |
| Dash camera | VWDCAM1-HDWL | Inside the cab | A forward view, and Visionworks says it can also serve as a security camera |
| Long-range 1080p camera | VWCAMAIO1-HDWL | Wherever you need an extra view | A general-purpose long-range camera (HD monitors only) |
| Rear indicator light camera | VWCAMRIL-HDWL | Built into a rear indicator light | Horse and cargo trailers that aren't pre-wired for a camera |
Visionworks rates the Gen2, side marker, license plate, long-range and rear indicator light cameras IP68 for harsh conditions, and all of these add-on cameras carry its 3-year camera warranty.
Side marker light cameras: the most useful second and third camera
A backup camera only helps when you reverse. On the road, the problem is the lane beside you, and a long trailer hides most of it. Visionworks' side marker light cameras are built into an amber side marker light, so they mount where your trailer or RV already has a marker light. That puts the camera at the side of the trailer, looking back along it.
The left camera (VWCAMSML1-HDWL) covers the driver side and the right camera (VWCAMSMR1-HDWL) covers the passenger side. If you want both, the pair (VWCAMSMP1-HDWL) is the simpler order. With a rear camera and both side cameras you're using three of the four slots. The Gen2 touchscreen monitors have a tri-view for exactly that layout.
One thing to check: a camera that takes the place of a marker light needs the trailer's marker light circuit to be live. Behind some newer trucks that power isn't steady. See the section on power below.
Example setups
| Rig | Start with | Add | Cameras in use |
|---|---|---|---|
| Travel trailer or fifth wheel, pre-wired for Furrion | Gen2 7" kit | Side marker pair | 3: rear + both sides (tri-view) |
| Same trailer, plus a forward-facing dash camera | Gen2 10" kit | Side marker pair + dash camera | 4 (quad view; the 10" keeps each picture readable) |
| Cargo or utility trailer, no pre-wire | 7" rear indicator light system | Side marker pair | 3 |
| Horse trailer | 7" interior and exterior system | Side marker camera on the side you can't see well | 3 |
| Tow vehicle with no camera | 5" magnet camera system | License plate camera | 2 |
These are suggestions built from Visionworks' published parts, not factory bundles. If your setup is different, tell us the rig and we'll help you choose.
Power for each camera
A wireless camera sends its picture without a video cable, but it still needs power where it is mounted.
- Gen2 camera: it uses the RV's pre-wire. The kits include the bracket and the 12V adapter. If you buy the camera on its own and the bracket is missing, the VWFPL bracket and adapter gives it a finished fit on RVs pre-wired for a Furrion camera.
- Side marker and rear indicator light cameras: these sit at a light position on the trailer.
- Semi trailers: the VWTLADP truck light adapter uses the existing 12V at the running lights and fits the connection used on most semi trailers.
- No power nearby: the VWMOBAT battery pack runs a Visionworks wireless camera with no wiring. It gives 6 to 8 hours per charge and comes with an AC/DC charger, a 12V charger and a magnet.
Newer trucks: many tow vehicles now use variable-voltage systems that don't always give the trailer the steady power a wireless camera needs. Visionworks' flyer names 2019 and newer Chevy/GMC and 2021 and newer Ford and Dodge. The VW7PMA 7-way power management adapter provides constant 12V to the trailer. Visionworks says it also lets you power marker lights and cameras when the RV is disconnected from the tow vehicle. Our answer on why a trailer camera cuts out behind a newer truck has the full checklist.
Signal: when more cameras need a better antenna
Visionworks quotes a wireless range of 1,000+ ft with good line of sight. The side cameras on a long trailer are closer to the cab than the rear camera, but a long trailer with solid walls puts more material between the cameras and the monitor. On trailers longer than 30 ft, or if you want to watch the cameras while driving (where the law allows) and not just when backing up, Visionworks recommends its roof-mounted booster antenna. It's a 7 dBi omni-directional antenna on a shielded 30 ft cable.
FAQ
How many cameras can I add?
Up to four cameras per Visionworks HD monitor, including the camera or cameras that came with the kit.
Will the side marker cameras work with my 5" magnet system?
Yes. Visionworks lists the side marker cameras as pairing with any Visionworks HD wireless monitor, and the magnet-camera systems use an HD monitor.
Does every camera record?
The monitor's built-in DVR records up to four cameras to an SD card of up to 256GB (not included).
Which camera do I add first?
For towing, the passenger-side side marker camera, because that's the side you see least in your mirrors. For a horse trailer, an interior view.
