Fleet dashcams that see the road, the driver and the blind spot

4G AI dashcams, multi-channel MDVRs and AI safety cameras for trucks, buses, taxis and service fleets. Live video and alerts in the Traqcare platform.

Drag to rotate

Dashcams for one to four cameras per vehicle, MDVRs for four or eight, and ADAS, DSM and BSD cameras that connect to the MDVRs.

Warns the driver before the collision

From the windscreen to the fleet manager

Every 4G model reports to the same platform. This is what happens between a driver closing their eyes and a manager seeing the clip.

  1. Step 1: Cameras

    Road, cabin, rear and blind-spot cameras. AI models for ADAS, DMS and BSD run on the device, so alerts don't wait for the network.

  2. Step 2: Recorder

    A dashcam or MDVR records every channel to SD card or hard disk. On models with a G-sensor, the clip around an impact is locked.

  3. Step 3: 4G uplink

    Location, alarms and event clips go out over 4G. Live video streams on demand, so you don't pay to stream all day.

  4. Step 4: Traqcare

    Fleet managers see live location, alarms and video in the web dashboard and the iOS and Android apps.

  5. Step 5: Action

    The driver gets a voice warning in the cab and the manager gets the clip. Disputes are settled with video, not guesswork.

Questions fleets ask first

All questions

What is Dashcam For Cars (D4C)?

Dashcam For Cars (D4C) is the fleet dashcam and MDVR brand of SKYWONDER Technology Co., Ltd., founded in 2011 in Guangdong, China, and working under an ISO 9001 quality system. D4C's 4G dashcams and MDVRs report to the Traqcare fleet platform.

Why does a fleet vehicle need a dashcam?

A fleet dashcam records the road, and on dual-lens models the cabin, with GPS position and time on each clip. That gives evidence for accidents, insurance claims and disputes. 4G models add live view, AI safety alerts and clips that upload themselves, so a manager sees an incident without waiting for the vehicle to return.

What types of cameras do you offer?

Ten [dashcams](/product-category/dashcam/): nine with 4G and GPS, and one Wi-Fi model. Three [MDVRs](/product-category/mdvr/) that record four or eight cameras. Five [cameras for MDVR systems](/product-category/accessories/): an ADAS camera, two DSM cameras, a BSD camera and an infrared dome camera.

What is an MDVR, and how is it different from a dashcam?

An MDVR (mobile digital video recorder) is a recorder mounted out of sight that records four or eight external cameras at the same time, to SD cards or a hard disk, and with 4G streams video to a platform. A dashcam is a single windscreen unit with one or two built-in lenses, and on some models a rear camera on a cable. MDVRs suit buses, trucks and heavy vehicles.

How do I choose the right model?

Tell us your vehicle types, the views you need (road, cabin, rear, sides, doors), whether you need live remote access and which AI alerts matter. We recommend a model and can send samples for testing. Our guide to [how many cameras a vehicle needs](/how-many-cameras-does-a-truck-bus-or-van-need/) covers the first step.

How much video can a dashcam store?

A 64 GB card holds about 33 hours of 1080p video from one camera, or about 8 hours from four, at the standard bitrate of D4C recorders (4 Mbps per camera, H.264). Loop recording then overwrites the oldest files, so the camera never stops recording. The [storage calculator](/dashcam-storage-calculator/) gives the figure for other setups.
