Samsara CM32 dash cam is the best dual dash cam due to video quality, features, integration with Samsara's fleet management system, and overall value for money.
A dual dash cam is a single camera with two lenses. It records video footage of the road ahead of a vehicle, while also filming the interior of the cab – including the driver. By recording two feeds simultaneously, a dual dash cam offers greater coverage, and provides greater insight than a single front-facing cam.
Dual dash cams are sometimes confused with “front and rear dash cams,” which refers to a system of two separate cameras that film both the front and the rear exteriors of a vehicle. This page focuses specifically on dual dash cams, which film the front and interior views while driving.

The Samsara CM32's front-facing camera lens records in 1080p HD and records a with 121 degree view. Meanwhile, the interior-facing camera records a still high quality 720p, and covers everything with a wide-angle 177 degree view.
The CM32 is sold by top fleet management software company Samsara, and has built-in operability with Samsara's service. Unlike many dash cams, it automatically uploads footage of specific events to the cloud, allowing a fleet manager to view incident footage within minutes of a collision or traffic infraction. In addition, on-demand video is available for the previous 40 hours of driving time, so managers can review a typical day at their leisure.
Another standout feature is the CM32's artificial intelligence (AI) tools, which can analyze a scene in real-time, detecting objects in order to identify near-misses, poor driver behavior like tailgating, and approaching road signs. The dash cam can then issue in-cab voice alerts as a warning if needed. It's a simple but effective use of AI, which has risen to prominence across many industries in 2023.
Additional features identified by our research team include driver scorecards, trend reports, infrared LED-powered night vision, and an internal accelerometer (called a G-sensor) that triggers video recording when it detects a collision.
Samsara offers a well-established fleet management service, and those already using its FMS are highly likely to settle on this dual dash cam. For those in the market for a fleet-wide dash cam update, this is a stellar choice, offering all the basic features a fleet needs while supplementing them with useful additions like AI and FMS operability.
The price tag is high, but a large fleet will quickly recoup that cost in the fleet-wide savings that come along with the greater safety, stronger insurance protections, and better data-driven decision-making enabled by the CM32.

The Lytx Drivecam's exterior camera films in 82 degrees, while the interior camera offers a more spacious 131 degree view. The resolution for both is 1280p x 800p – while this isn't a standard HD resolution, it's essentially the same as 720p HD, and fully qualifies as high definition. This camera should work fine for capturing clear, accurate footage of traffic signs or license plates.
A separate device, the Lytx Hub adaptor, can be purchased and used to add up to four additional camera units to the Lytx Drivecam, allowing a truck to keep an eye on the rear and side views as well as the front and interior.
This two way dash cam comes packed with features. Additional abilities include an omnidirectional microphone and a speaker for audible in-cab alerts, night vision for the interior cam, GPS location tracking, and a two-year warranty.
The dash cam can record up to 100 hours of continuous looping video footage, as long as it has a large enough SD card. And, like the CM32 dash cam, it comes integrated with artificial intelligence tools for enhanced risk detection and prevention.
Finally, a particularly useful aspect of the Lytx dash cam is a video dashboard that managers will find easy to search. They'll be able to find video files by date and location, gaining insights from data covering each vehicle's speed and fuel use (helpful for the cash-strapped trucking industry in 2023). The cam is cloud-connected, so managers can receive near-real-time video updates, which will help them cut down on back-and-forth messages while responding rapidly and streamlining productivity.
Since this model works so well with the Lytx vehicle tracking software, it's another option that will be attractive to fleet owners or managers in need of a unified fleet management solution. The dash cam's video quality isn't as high as others on this list, but it offers an unbeatable range of features, even before you get to the easy-to-use dashboard that makes this offering extra appealing to data-hungry managers.

The Vantrue N2 Pro records with a crisp, 1080p HD, 170 degree exterior camera view and a 1080p HD, 140 degree interior camera view. Both cameras can record simultaneously at 1080p and 30fps, or just the front one can be set to record to an even higher quality, at either 1440p and 30fps or 1080p and 60fps. Either way, this camera records the highest quality video you'll find for a dual cam across the board.
A 1.5-inch display allows drivers to watch video locally, and a low-power 24-hour parking mode allows the camera to turn on and begin recording if it senses movement, even when the vehicle is switched off. The dash cam can be set to power on whenever the car is turned on, too, and the LCD light can be turned off so that the screen's glow won't distract the driver.
The Vantrue includes a night vision ability for the interior cam only. It's powered by four infrared LED lights that let it capture a clear grayscale view of the vehicle interior, even in pitch black conditions.
Features also include motion sensing, a collision-detecting G-sensor which saves recorded video when it senses an impact, a built-in microphone and speaker that plays chiming audio alerts, and a maximum SD card storage functionality of up to 256GB (although you'll likely need a high endurance SD card, such as a Samsung or SanDisk).
A GPS tracking add-on mount is sold separately, and can be used to track vehicle speed and location.
If you want a high-quality, durable dash cam, look no further. The Vanture N2 Pro's HD video and wide-angle views are top of the line with sharp colors and contrasts, and it offers a broad range of useful features. The display screen isn't as large as most options our team tested, but if you want good video footage at a reasonable price, this dual dash cam is a great pick.

Unlike most dual dash cams, the Nexar Pro system actually uses two camera units to film the cab and front exterior, connected with a short cable. You'll have a 1080p HD, 135 degree view of the road, with 720p interior view.
The hardware also offers a motion detecting G-sensor and built-in GPS. Storage starts at 32GB, but the right SD card can expand this to as much as 256GB, which supports 24 hours of local backup footage. A low-power 24-hour parking mode allows the camera to turn on and begin recording if it senses movement, even when the vehicle is switched off. The camera can also livestream footage to your phone.
The interior camera has a 10 infrared lightbulb array to ensure it can keep filming the cab even at night (this is a great perk, as our research team found many similar night vision cameras only offer two or four lights).
The camera system comes with an app that allows users to modify their setup: You can use the app to log potential break-ins, track GPS data, create incident reports, and back up video clips to cloud storage. The reliance on an app could be considered a downside, however, since it means you'll always need a smartphone to operate the dash cam. Nexar says that its Pro camera is compatible with iPhone 7 and newer models, as well as “most” Android devices.
Ease of use is a big selling point for the Nexar Pro. You can generate an accident report in less than a minute with the app, complete with an autogenerated summary of footage, driving speeds, G-force impact, and location. Plus, a similar “Emergency Alerts” mode can save a video clip, log your location, and dispatch 911 with one click.

The Transcend Drive Pro 550 has a full HD, 1080p, 160 degree front view, and a 720p HD, 110 degree interior lens. The unit is a cost-conscious pick, as it includes plenty of features that are often a few hundreds dollars more expensive.
This is most evident in the range of alerts that can be set up: A driver fatigue alert to remind the driver to take a break at a preset time, a headlight reminder that's triggered when the camera detects poor lighting conditions, a “forward collision warning system” that's triggered when the vehicle is too close to the one ahead, and a lane departure warning to alert the driver if their vehicle veers out of its lane. These tools are relatively rare for a dash cam, but are useful for helping inexperienced drivers avoid dangerous and costly collisions.
Our research found two other (more common) helpful features available from this small, blocky dash cam: A built-in GPS location tracking function that can be synced to Google Maps and logs time-stamped locations, speeds, and dates, as well as a G-sensor for collision detection and emergency recording. If the G-sensor detects an incident, it will stop the device from overwriting the relevant video footage.
It comes with a 32GB or a 64GB microSD card, but can hold up to 128GB. The device's 110 degree coverage of the cab is okay, although it could be better: A previous model, the Pro 250, covered 180 degrees. While not exactly cheap, the Transcend Drive Pro 550 is priced lower than most dual dash cams – making it an attractive choice for the cost-conscious dash cam shopper.

Benefits of Dual Camera Dash Cams
What do dual dash cams have that a single front-facing camera lens doesn't? They offer more comprehensive coverage of the vehicle they survey – and that comes with a handful of worthwhile benefits. Here are a few top reasons why the dual dash cam's exterior and interior views are worth the cost, and may qualify as the best dash cams for truckers.
Safety while driving
Driving while an in-cab camera watches you might not sound appealing to some drivers, but a good dash cam offers plenty of useful safety features. An AI-powered dash cam can issue audio alerts when it detects poor driving choices, such as tailgating, or when it notices a driver's eyes aren't on the road. Ultimately, dual dash cams help create a safer environment inside as well as outside the vehicle.
Safety inside vehicle
A dual dash cam's interior view sets it apart from a typical front-facing camera. By monitoring the interior of the vehicle, a driver can make sure they keep all their family members or friends covered. In the event of an accident, the video footage could offer useful data that may confirm how, when, and where someone may have been injured.
In the trucking industry, a collision that results in an injury costs an average of $200,000. With a dash cam that records the interior of a truck cab, a fleet owner can confirm that their drivers' eyes were on the road, and that they're not the ones at fault.
Fleets don't need to wait for a collision to save money, either – with regular dash cam coverage, some insurance plans may lower their premiums.
Vehicles with frequent passengers can benefit from a dual dash cam's interior camera keeping an eye on every new passenger. Any taxi or ride-share service constantly sees passengers come and go, and other service industries, like tow trucks, also regularly ferry their clients around as passengers.
The added documentation of a video surveillance feed ensures that passengers' behavior is recorded for future reference. And, since any unremarkable video footage is quickly recorded over, passengers won't need to worry about footage of them remaining once they're gone.
The mere presence of a dash cam can deter theft, and the blinking lights of a motion-detecting camera turning on can be enough to scare away most burglars. With a dual dash cam, you'll greatly increase the odds of actually recording footage of a break-in – most smash-and-grabbers break a side window to get in, which a front-facing camera wouldn't catch. The interior-facing lens on a dual cam, however, typically has the infrared LEDs needed for night vision, and can catch a car thief in the act.
