# Dashcams and camera systems for trucks

Most trucks need three or four camera views: the road, the cab, the nearside blind spot and the rear. A dual-lens 4G AI dashcam such as the D9 covers the road and the cab and takes two more 720p cameras. Trucks that need four 1080p views use a 4-channel MDVR such as the WD12, which takes a BSD camera when ordered with the BSD option.

- Camera views: 3 to 4
- Recorder: D9 dashcam or WD12 MDVR
- Storage: microSD or dual SD, up to 512 GB

## What goes wrong

- **Disputed collisions.** Without video, liability rests on statements. Road and cab footage, stamped with GPS position and time, shows what happened on both sides of the windscreen.
- **Fatigue on long hauls.** A driver-monitoring camera detects yawning and closed eyes and sounds a warning in the cab. On the D9 it is the built-in infrared cabin lens, so it works at night.
- **Blind spots at junctions.** Cyclists and pedestrians alongside the cab are hardest to see during a nearside turn. A side-mounted camera covers that zone and records side-swipe incidents.

## Recommended camera layout

A dual-lens AI dashcam covers the road and the cab, and takes two more cameras for the nearside and the rear. Trucks that need four 1080p views or blind-spot detection move up to a 4-channel MDVR.

| Position | Equipment | What it covers |
|---|---|---|
| Windscreen, facing the road | [D9 road lens, 1080p, 135°](https://dashcamforcars.com/product/d9-dual-lens-dashcam/) | The road ahead, with forward-collision, lane-departure, pedestrian and following-distance warnings |
| Windscreen, facing the cab | [D9 infrared cabin lens, 1080p](https://dashcamforcars.com/product/d9-dual-lens-dashcam/) | The driver, day and night, with yawning, closed-eye, distraction and smoking alerts |
| Nearside of the body | [External 720p camera on the D9, or a BSD camera on an MDVR](https://dashcamforcars.com/product/bsd-camera/) | The blind spot alongside the cab and trailer |
| Rear | External 720p camera | Reversing incidents and rear-end collisions |

What this setup gives you: Forward collision and lane departure warnings, above 30 km/h on the D9; Fatigue and distraction alerts that sound in the cab; Incident clips uploaded over 4G for claims.

## Products in this setup

- [D9](https://dashcamforcars.com/product/d9-dual-lens-dashcam/): Road and cab, ADAS and DMS
- [WD12](https://dashcamforcars.com/product/wd12-mini-dual-sd-card-mobile-dvr/): 4-channel recorder
- [BSD camera](https://dashcamforcars.com/product/bsd-camera/): Nearside blind spot

## Storage and mobile data

Recording 1080p + 1080p + 720p + 720p at standard quality on a 512 GB microSD card, the largest the D9 takes keeps roughly 76 hours of recording with H.264, or about 151 hours in H.265, which the D9 supports. Recording uses no mobile data. Tracking uses about 17 MB a month; live view on the sub-stream uses about 40 to 60 MB per camera per hour.

## Before you order

- The D9 and WD12 run on 9–36 V and the WD10 on 10–36 V, so the same equipment fits 12 V and 24 V trucks.
- On the D9, calibrate ADAS and DMS in the app after mounting. Alerts are active above 30 km/h.
- Recording to the card uses no mobile data. A 4G data SIM is needed for live view, alerts and clip upload.
- For MDVR systems we recommend professional installation and provide wiring guidance and remote support.

## FAQ

### What is the best camera setup for a truck?

A road camera and a cab camera are the minimum. Most truck fleets add a nearside blind-spot camera and a rear camera, for four views. The D9 dashcam covers the road and cab and accepts two external cameras; the WD12 MDVR records four external cameras.

### Does a truck need a dashcam or an MDVR?

A dashcam is enough when you need the road, the cab and up to two extra 720p views. Choose an MDVR when you need four 1080p inputs (WD12), up to eight 720p cameras (WD10) or a recorder mounted out of sight. Blind-spot detection is an option on both the WD02 dashcam and the WD12 recorder.

### Do truck dashcams work on 24 V?

Yes. The D9 and WD12 accept 9–36 V and the WD10 accepts 10–36 V, which covers both 12 V and 24 V vehicles.

### Can the office see a truck's cameras live?

Yes. Over 4G, managers watch live video, play back and download clips, and follow the vehicle on the map in the Traqcare app or web platform. A data SIM is required.
