The dēzl DualView is a two-camera system that mounts to the outside of a commercial truck (or RV, bus, or large vehicle) and provides a continuous, live video view down each side of the vehicle. Video streams wirelessly to a paired tablet, dēzl OTR truck navigator, or compatible RV navigator inside the cab. The system includes blind-spot monitoring with merging alerts and automatically records detected incidents in 1080p HD video to a microSD card.

The system uses its two side-mounted cameras to detect vehicles entering your blind spots and approaching during lane changes. When a vehicle is detected alongside your truck, you receive a visual alert on your paired display. When paired with a dēzl OTR navigator, the system can also trigger automatic camera views when you reduce speed or activate your turn signals.

You need a microSD card (not included) between 16 GB and 512 GB, Class 10 or faster. Video is recorded at 1080p HD when incidents are detected. Without a microSD card installed in the transmitter box, the system still provides live video and blind-spot alerts but cannot save recordings. Note: some jurisdictions regulate or prohibit the use of camera devices — check local laws.

Vault is Garmin’s optional paid cloud storage plan. With a Vault subscription and a Wi-Fi connection, saved video clips are automatically uploaded and stored online. You can view and share clips from the Garmin Drive app on your smartphone or tablet. Without a Vault plan, videos remain stored locally on your microSD card.

Yes. The cameras are rated IPX7, meaning they can withstand submersion in up to 1 meter of water for 30 minutes. Garmin also rates them to withstand pressure washers, fuels, chemicals, sunlight, rain, and other harsh environmental conditions typical of commercial truck use.

The cameras mount to side mirrors or other flat surfaces using either screw-down base plates or adhesive base plates. The transmitter box mounts inside the vehicle within 3 meters (10 feet) of your display device. Power connects to a 12V or 24V vehicle power source (hardwired, not battery-operated). Turn signal wires connect via included tap splice connectors for automatic camera views on signal activation. Garmin recommends professional installation. Camera lenses are adjustable — tilt up to 45° and roll up to 180° — and alignment is done through the Garmin Drive app.

You can view the live feed on a paired tablet, a Garmin dēzl OTR truck navigator (such as the dēzl OTR720, OTR810, or OTR1010), or a compatible Garmin RV navigator. When paired with a dēzl OTR navigator, you can use voice commands (available in English, German, French, Spanish, Italian, Danish, Dutch, and Swedish) to control camera views. Saved videos can show GPS data overlays — location, speed, date, and time — when paired with a dēzl OTR navigator or a GPS-enabled Garmin dash cam.

Yes. You can network up to 3 additional Garmin cameras (each sold separately) to add front-facing or rear-facing views. The DualView system itself provides left and right side views; additional cameras extend coverage to the front or rear of the vehicle.

The dēzl DualView package includes two camera modules, a transmitter box, camera base plates with adhesive mounts, mounting hardware (screws, washers, nuts, hex wrench), tap splice connectors for turn signal wiring, an in-line fuse cable, and documentation. A microSD card is not included and must be purchased separately.
