Expert Verdict (2026) - Why Buy?
Choosing between the Steelmate C20 and C40? The C40 is the clear choice for vehicles where side-impacts and pedestrian awareness are a concern. While the C20 covers you front and back, the C40 adds Side AI Cameras that specifically look for moving objects in your 'danger zones.
The jump to a 10.1-inch screen (up from 7 inches on the C20) makes a significant difference when using the 4-way split-screen mode, ensuring every angle is large enough to be useful at a glance. We love the inclusion of the AI Pedestrian Detection, which makes this system especially valuable for city-driving delivery trucks and urban contractors.
Choose this camera for the attractive price point, the included AI Blind Spot warning system, and AI pedestrian detection system, along with it’s included left and right turn signal inputs, that allow seamless video switching of the left and right cameras when you activate the turn signals. Also the reverse light input allows seamless rear camera video switching when you place the vehicle in reverse. Downside is no parking mode available, a limited storage capacity of only 128GB, and the lower 720p resolution.
But the price point makes this a very attractive commercial dash camera option.
Steelmate C40 is a practical multi-camera safety solution for fleets, work trucks, vans, and other commercial vehicles. It combines a C40 multi-camera recorder, a 10.1-inch LCD monitor, hands-free voice control, and AI blind spot detection in one integrated system.
Designed for drivers who need better visibility and faster awareness, this 4-camera dashcam setup helps monitor the road, surrounding lanes, and rear areas with clear, continuous coverage.
Four-channel recording with a built-in monitor
The system records from all four cameras through the built-in screen, making it easier to review incidents as they happen. Each channel is saved separately, and recording begins automatically when the ignition is switched on.
- 720p AHD cameras on all four channels
- 30fps recording for smoother video capture
- 10.1-inch LCD monitor with touch operation
- Split-screen viewing options for 2-way or 4-way display
- Automatic file separation by camera channel
Hands-free voice control for safer operation
Voice commands let the driver control key functions without taking attention away from the road. That means you can change views, manage audio, or switch the screen state by speaking simple commands.
Common voice functions
- Turn the screen on or off
- Mute or restore audio
- Show the front camera
- Show the rear camera
- Display both cameras or return to a split view
For busy commercial driving environments, this kind of hands-free control adds convenience while supporting safer day-to-day operation.

AI blind spot detection for commercial vehicle awareness
The side cameras use intelligent detection to identify nearby moving people and alert the driver when activity is detected in the blind spot zone. This makes the system especially useful when manoeuvring in tight areas, reversing, or working around pedestrians and obstacles.
The camera package is also built for usable footage in difficult lighting conditions, with a wide 160° viewing angle and image performance suited to early mornings, late evenings, and enclosed work sites.
Built for fleets, trucks, and heavy-duty use
The Steelmate C40 is a strong fit for commercial applications where visibility matters. It is well suited to:
- Delivery vans
- Commercial trucks and rigs
- Agricultural equipment
- Construction machinery
- Trailer and fleet installations
Because the cameras are compact, installation is easier in a wide range of vehicle layouts. The system also supports additional AHD cameras if your setup requires more flexibility.
Installation notes to know
- Use the M12 flexi cable for truck and trailer applications
- CH3 and CH4 can trigger automatic split-screen display when wired to 12/24V
- Continuous recording and on-screen playback help review events right after they occur
This makes the AI blind spot detection system especially useful for operators who need dependable coverage, simple playback, and a clear view from the cab.
Frequently asked questions
Can the monitor be controlled without using the touchscreen?

Quick Response
Had good experience a few years ago with parking sensor installs (front and rear) for 2 cars. Just got 2 dashcams installed. Duane gave quick responses online with a very reasonable price. Both cars, front and rear cams installed professionally and looks seamless (tech was very informative). Leo and Titus - front desk - took care of things efficiently, answered all my questions in a friendly manner. Got my cars back in the time specified. Very good selection, service, installation.

Extremely Professional
Everyone at Lockdown was extremely professional, knowledgeable and pleasant. They also had the additional hardware I needed rather than ordering it separately beforehand. Leonardo was very patient answering my questions and going through how to set up and use my new Dashcam. Sal was great going over the installation process and asking me questions how I wanted it installed. I would highly recommend their services.

Awesome Experience
Just installed the thinkware q200 dashcam today with awesome experience. Booking the appointment is easy and service is excellent. After the installation, staff also walked me through the set up and everything is done within 2 hours. The cost is same as the website shows and no other hidden cost. Highly recommended. 👍
