Our Picks: Best Truck Dash Cams For Semi Trucks reviews
1. MirthWorld 4-Channel System for Four Camera Views
The MirthWorld system pairs four cameras with a roughly 10-inch monitor, giving you a way to view several areas around a truck or trailer from the cab. The supplied description lists two rear cameras and two side cameras, with split-screen viewing for checking multiple angles at once. That layout is useful when a single rear-facing camera does not show enough of the vehicle’s surroundings.
The cameras are described as IP69K-rated and built to handle vibration, dust, and water. Infrared night vision and a 120-degree viewing angle are also listed. The system supports loop recording, so it can function as a dash cam as well as a live-view backup system. Its wide 12–24V input is intended to work with many vehicle types, but it does not cover the broader voltage range of some commercial-focused alternatives here.
Installation uses wired connections, and the display is designed to switch to a camera view when connected to the reverse gear. Before ordering, check that the included cable lengths and camera positions fit your particular tractor and trailer. The product details do not specify memory-card capacity, so confirm the recording-storage requirements before relying on it to save footage.
Pros:
- Four cameras provide multiple side and rear views.
- Large display supports split-screen monitoring.
- IP69K-rated cameras and infrared night vision are listed.
- Loop recording adds dash-cam functionality.
Cons:
- The listed 12–24V input may not suit every commercial electrical system.
- Storage capacity and card requirements are not specified in the supplied details.
Verdict: Choose the MirthWorld if your priority is a four-camera live-view setup with a large monitor, and confirm the wiring and recording-storage details before installation.
2. ATOVANKA Four-Camera System with CarPlay
ATOVANKA combines four wired 1080p cameras—front, rear, left, and right—with a 10.36-inch touchscreen. Its four-angle layout is intended to give drivers broad visibility around the vehicle, while the display offers multi-source viewing. The cameras are wired, which avoids relying on a wireless camera signal for the main video connections, but does mean installation involves routing long cables.
The display supports wireless CarPlay and Android Auto, plus FM audio output. Those features may suit drivers who want navigation and phone-based functions alongside camera views. The system is listed for 12–36V vehicles and includes cables up to 65.6 feet, making it a flexible option for larger rigs, though cable routing still needs to be planned around the truck and trailer configuration.
Other listed features include IP69K-rated cameras, night vision, and ACC-powered time-lapse parking surveillance. The supplied package information says a microSD card is not included, so plan for separate storage and confirm the supported card specifications. The main tradeoff is complexity: this system brings more connectivity and camera coverage than a basic dash cam, but also requires a more involved install and setup.
Pros:
- Four 1080p cameras cover front, rear, and both sides.
- Large touchscreen includes wireless CarPlay and Android Auto.
- 12–36V support and long cables suit many commercial vehicles.
- Parking surveillance and weatherproof camera ratings are listed.
Cons:

Verdict: The ATOVANKA is a strong fit if you want four wired camera angles, a large display, and smartphone integration in one system.
3. VSYSTO T4.5M Three-Channel Dash Cam with GPS
The VSYSTO T4.5M records from three positions: front, left, and rear. It uses a 4.5-inch monitor for live viewing, with a choice of full-screen or split-screen layouts. The front camera is listed at 1080p, while the side cameras use 720p sensors. This is a more compact display than the larger monitor systems above, but the dedicated recording unit includes features aimed at managing footage and reviewing driving information.
Built-in Wi-Fi connects the dash cam to a phone app for viewing and managing video, and GPS tracking records information such as speed and coordinates. A G-sensor can protect footage associated with a collision, while loop recording reuses space by replacing older files. The system supports microSD cards up to 256GB; check the package details for whether a card is included.
The side cameras have infrared night vision and an IPX7 waterproof rating, according to the supplied details. Adjustable mounts and cables of different lengths allow some flexibility in camera placement, and the system is listed for 12–30V vehicles. It lacks the large display and four-camera coverage of the first two picks, so it is better suited to drivers who value recording tools and GPS over a full four-sided monitor view.
Pros:
- Records front, left, and rear views at the same time.
- GPS and Wi-Fi app support add route and video-management tools.
- G-sensor protection and loop recording help manage saved footage.
- Supports microSD cards up to 256GB.
Cons:
- The 4.5-inch screen is smaller than the monitors on several other picks.
- Side-camera resolution is lower than the front camera’s listed resolution.
Verdict: Consider the T4.5M if you want three-angle recording with GPS and app access, and do not need a large in-cab monitor.
4. VSYSTO V7M Three-Channel System with a 7-Inch Monitor
The V7M is a three-camera setup with a 7-inch monitor. The front camera is listed at 1080p, and the two exterior side cameras at 720p with infrared night vision. You can use the display for split-screen viewing or switch to a full-screen camera. A sun visor is included to help reduce glare, a practical touch for a monitor mounted in a bright cab.
The system supports 12–30V vehicles and includes a hardwire kit for parking mode. Its listed parking features can record after movement or a collision, or at preset intervals. Wi-Fi app access and GPS tracking are also included in the supplied description. A turn-signal connection can bring up the corresponding side-camera view, and the system also offers camera switching through a remote control.
This model offers a larger screen than the T4.5M while retaining a three-camera layout and similar GPS and Wi-Fi features. It is not a four-camera system, and the description’s parking-mode details should be checked against your intended wiring setup. A memory card is not included, and the system supports cards up to 256GB according to the supplied product information.
Pros:
- 7-inch screen offers a more visible display than compact dash cams.
- Includes GPS, Wi-Fi, and turn-signal camera switching.
- Hardwire kit supports the listed parking-mode functions.
- Side cameras include infrared night vision.
Cons:
- Three cameras do not provide the four-angle coverage of some alternatives.
- Storage card is not included.
Verdict: The V7M is a good match if you want a dedicated 7-inch screen and three-camera recording with GPS, app access, and parking-mode features.
5. VSYSTO 3CH Wi-Fi Dash Cam for a Compact Setup
This VSYSTO model records from a front camera and two separate side cameras, with a 3-inch LCD screen built into the unit. Its compact display takes up less space than the larger monitor systems, but it is not designed to provide the same broad, easy-to-scan live view from across the cab. The side cameras can be connected to turn-signal power so the display switches to the matching side view when turning.
The product details list infrared night vision and an IP67 waterproof rating for the separate cameras. Wi-Fi connects the dash cam to the VSYSTO app, where you can view and manage footage without removing the card. Loop recording replaces older files when storage is full, and the G-sensor can protect footage after a collision. The system supports microSD cards up to 256GB.
Compared with the T4.5M and V7M, this model offers a smaller screen and a simpler feature set; GPS is not listed in the supplied details. Its compact design may appeal if you want front and side recording without a large separate monitor. Confirm that the camera cable lengths and mounting positions work for your truck, since the supplied description does not list cable lengths.
Pros:
- Three cameras record front and side views.
- Wi-Fi app access supports video viewing and management.
- Infrared night vision and IP67-rated separate cameras are listed.
- G-sensor and loop recording help protect and manage footage.
Cons:
- The 3-inch screen is much smaller than dedicated monitor systems.

How to Choose a Truck Dash Cam for a Semi Truck
Decide How Many Camera Angles You Need
Start by listing the areas you want to see or record. A front camera captures the road ahead, while side cameras can help with turns and lane changes. A rear camera can be useful for backing and monitoring a trailer area. Three-camera systems in this list cover front and two additional views; the four-camera systems add another angle. Check each product’s stated camera positions rather than assuming that all kits use the same layout.
Choose Between a Dedicated Monitor and a Compact Screen
A larger monitor can make it easier to view several camera feeds at once, especially when the system offers split-screen mode. The products here range from a 3-inch built-in LCD to monitors around 10 inches. A smaller unit takes up less cab space, while a large screen needs a suitable mounting location and should not block your view. Think about where you can place the display before choosing a system.
Check Voltage Compatibility and Cable Length
Commercial vehicles can have different electrical setups, so compare your truck’s system with the dash cam’s stated input range. The options here list ranges from 12–24V to 12–36V. Also check cable lengths and the location of each camera. Long runs may be needed between the cab, tractor, and trailer, and a camera kit’s included cables may not suit every vehicle layout.
Understand Recording and Storage Features
Loop recording helps keep a dash cam recording by replacing older files when storage fills up. A G-sensor may protect footage associated with a collision. Look for the maximum supported microSD card size and check whether a card is included; some systems explicitly require a separate purchase. Consider how often you will need to save or transfer footage, since app access and card handling differ by model.
Consider Night Visibility and Weather Protection
Side and rear cameras mounted outside the cab need protection from rain, dust, and road conditions. Compare the listed water-resistance ratings, and note that ratings can differ between cameras in the same kit. Infrared night vision is included on several options here, but the camera resolution and features may not be identical across all views. Match the camera capabilities to the areas you need to monitor.
Look at Parking Mode and Installation Needs
If you want recording while the truck is parked, verify exactly how parking mode works and whether the kit includes the required hardwire cable. Some systems list time-lapse, movement, or collision-triggered recording, while others do not list parking features. Also consider whether you are comfortable routing power and camera cables yourself or need a professional installer. Follow the manufacturer’s wiring instructions for your vehicle.
Separate Driving Assistance from Dash-Cam Evidence
A camera monitor can help you see nearby areas, and a dash cam can preserve footage, but neither replaces mirrors, safe driving practices, or a proper vehicle inspection. If you need footage for a specific purpose, check how the system records, how files are protected, and how easy it is to retrieve them. Do not assume a live-view backup system and a recording dash cam offer identical functions.
Frequently Asked Questions
What is the difference between a truck dash cam and a backup camera system?
A dash cam is mainly designed to record driving footage, while a backup camera system focuses on showing a live view on a monitor. Some products combine both functions, but recording features, camera views, and storage support vary. Check the product details to confirm what each system actually records.
Are three cameras enough for a semi truck?
Three cameras can cover the front and two additional positions, such as the left and right sides or a rear view. Whether that is enough depends on your vehicle and the areas you want to monitor. A four-camera system offers another view, but you should still confirm the camera placement included in the kit.
Do these systems work with trailers?
Some of the listed systems are described for trucks, trailers, buses, or other commercial vehicles, and cable lengths vary. Before buying, compare the included cable length with the distance from the display to each camera. Check the product details for any trailer-specific wiring or expansion requirements.
Do I need to buy a memory card separately?
That depends on the system. The ATOVANKA package information says a microSD card is not included, and the VSYSTO V7M details also state that a card is not included. For the other models, confirm the package contents and supported card capacity before ordering.
Can a truck dash cam record when the vehicle is parked?
Some models list parking-mode functions, but they may need a hardwire connection and can use different recording triggers. The ATOVANKA lists ACC-powered time-lapse surveillance, and the VSYSTO V7M lists a hardwire kit with parking-mode options. Check the installation instructions and power requirements for the specific system.
Will the cameras record clearly at night?
Several systems list infrared night vision for their exterior cameras. Low-light performance can differ by camera, so check the details for the particular view you need. Night vision does not guarantee that every image will be equally clear in all lighting and weather conditions.
Which option is best if I want a large screen?
The ATOVANKA has a listed 10.36-inch touchscreen, and the MirthWorld system has a display around 10 inches. The VSYSTO V7M has a 7-inch monitor. Choose based on the screen size you can mount safely and the camera layout you need.
Final Recommendation
For the broadest camera coverage and a large display, the ATOVANKA four-camera system is the most feature-rich option in this group, with CarPlay, Android Auto, and a stated 12–36V input range. The MirthWorld is another four-camera choice if split-screen viewing is your main priority, though its listed voltage range is narrower and its storage details should be checked. If you prefer three-camera recording, choose the VSYSTO T4.5M for GPS and app-based video management, the V7M for a larger monitor and listed parking mode, or the compact VSYSTO 3CH for a smaller screen and Wi-Fi access. Before you buy, confirm camera placement, cable length, vehicle compatibility, and memory-card requirements for your exact rig.
