A 3-channel (3CH) dash cam records your drive from every critical angle: the road ahead, the view behind, and the interior of your vehicle.
The interior lens typically features infrared (IR) lights for clear recording day or night, making these systems indispensable for ride-share drivers and valuable for any family road trip or daily commute. Some models, like the 70mai T800, even feature a physical privacy button for the interior camera.
Choosing the right one depends on your priorities: Is it crystal-clear 4K video, cloud connectivity, or the simplest installation? We’ve tested the top models to help you decide. Here’s our comparison of the best 3-channel dash cams of 2025/2026.

What To Look For In A 3CH Dash Cam
When deciding which 3-channel dash cam to buy, first of all you obviously want the best video quality you can get for your money. But which other features should you look out for?
Cloud Connectivity
One cutting-edge feature is the option to connect the camera to the cloud, so you can view live video from your car and receive notifications on your phone. Not all dash cams support this: 70mai and Vantrue have a cloud, Viofo doesn’t.
Bear in mind that connecting to the cloud comes with additional cost: Depending on the camera model, you’ll need either an LTE module or a wireless access point in the car, plus a SIM card and data plan. Some dash cam brands also charge a subscription fee for their cloud service.
For a detailed cost analysis, as well as an exact description of cloud features that each brand offers, check our article on cloud connectivity.
Parking Mode
When powered with a hard-wiring kit (not included by default), all the dash cams featured here support time-lapse and impact-triggered parking modes. Some also support buffered parking mode.
We consider buffered parking mode to be the best option, since it records continuous video and if an event is detected, it saves the footage starting some time earlier. This makes it easier to identify any perpetrator.
Ease Of Installation
A separate interior camera means one more cable and one more device to be installed. If the interior camera is built into the main unit, installation is easier and you have less clutter on your windshield.
Dash cams with an integrated interior camera allow you to rotate the lens up and down, so you can point it at the passenger cabin no matter the angle of the windshield.
Budget
As for pricing, good quality 3CH dash cams start around $150-180, and go all the way up to $400 for the high-end models.
Wi-Fi 6
The newest dash cams (T800 and A329S) support Wi-Fi 6, which is 3-4 times faster than Wi-Fi 5.
For example, the Viofo A329S can transmit videos at ~33 MB/s, while the A229 Plus reaches transfer speeds around 9 MB/s. The 70mai T800 can send video at up to 40 MB/s.
Miscellaneous
Other differences between the cameras shown below are:
- CPL filter inclusion
- Availability of rear CPL
- GPS: Dual, triple, or quad-band
- Optional accessories such as a Bluetooth remote button (Viofo, Vantrue)
- External storage support (A329S only)
- Waterproof rear camera (Vantrue N4 Pro S only)

Full Review: 70mai T800 Review
Our absolute favorite as of December 2025, the 70mai T800 records hands down the best video quality we have seen. During the day, video quality is excellent for all three channels (front, rear, and interior). At night, quality is good across the board.
Unlike the other cameras featured here, the T800 records at 4K resolution not only with the front, but also with the rear camera. Both use Starvis 2 sensors and support HDR for clear images in difficult lighting situations. For sample videos, visit the full review of the 70mai T800.
With excellent usability and optional CPL filters for the front and rear cameras, this well-rounded dash cam is our clear top choice for the year.
Customer support by 70mai is reliably good, as well.
If you get the corresponding LTE module (UP05 in America, ~$50) and a SIM card with data plan, you can connect the T800 to the cloud and stream video to your phone.
Privacy feature: The second button in the row can be used to enable/disable the interior camera when needed.

Pros: Best video quality, very reliable, app easy to use
Cons: High price, no cloud
Full Review: Viofo A329S Review
The A329S is Viofo’s flagship in 2025. Its video quality is almost, but not quite, as good as the T800’s.
A feature we really like is the 210° fisheye interior lens, which in addition to the passenger cabin also records the view out of both front side windows simultaneously. This comes in handy in the event of a traffic stop, or an interaction with pedestrians (or customers if you’re a taxi or ride share driver).
Like the T800, the A329S also supports fast Wi-Fi 6 connectivity, at 2.4 and 5 GHz frequency.
Another unique feature of this camera, apart from the fisheye lens, is that it allows you to connect an external hard drive (up to 4TB SSD) for expanded storage. Memory cards are supported up to 512GB size, so an external SSD gives you up to 8 times higher capacity.
While Viofo dash cams don’t use the cloud, models like the A329S use quad-band GPS (GNSS) to deliver pinpoint location accuracy—all stored reliably with your footage.
Vantrue N4 Pro S – Easiest To Install, Waterproof Rear Camera, Cloud
Price: Amazon US / CA / UK – more countries & vendors (ad)
Forward Resolution: 4K
Rear Resolution: 1440p
Interior Resolution: 1080p
Total Video Score: 3.2/5
Interior Camera: Integrated
Parking Modes: Buffered, impact, time-lapse, low bit rate
Other Features: Wi-Fi 5 (2.4 GHz and 5GHz), dual-band GPS, rear camera IP67 certified, optional CPL for front camera, optional Bluetooth remote button
Pros: Large screen, waterproof rear camera, cloud option, easy to set up due to integrated 3rd camera
Cons: Mediocre night video for the rear and interior channels
Full Review: Vantrue N4 Pro S Review
Another popular player in the dash cam market is Vantrue. Their latest 3-channel dash cam is called N4 Pro S, and it produces very good video quality with the forward camera, both during the day and at night.
With the rear and interior channels, it reliably produces very good video during the day, but at night, rear and interior video is mediocre to fair.
As an additional bonus, the rear camera is waterproof. This makes it ideal for use in (or on) a truck, or for any other vehicle that doesn’t have a rear window.
Like the T800, the Vantrue N4 Pro S supports cloud connectivity. For that, you need Vantrue’s LTE module (Amazon sponsored link), which is priced around $150 so be aware of the extra cost. In comparison, the 70mai UP05 module is only $50.
Why Is The Vantrue N4 Pro S The Easiest 3CH Dash Cam To Install?
Because it has the interior camera integrated with the main unit. One less device to install, plus less clutter on your windshield. The 70mai T800 also has an integrated interior camera, but the cable to the rear camera is thicker and thus slightly more difficult to tuck behind the car’s interior lining.
Viofo A229 Plus 3CH – Best Value For Money
Price: Amazon US / CA / UK – more countries & vendors (ad)
Forward Resolution: 1440p
Rear Resolution: 1440p
Interior Resolution: 1080p
Total Video Score: 3.7/5
Interior Camera: Separate
Parking Modes: Buffered, time-lapse, low bit rate
Other Features: Integrated quad-band GPS, Wi-Fi 5 (2.4 GHz and 5GHz), optional front CPL filter, optional remote Bluetooth button
Pros: Very reliable, app easy to use, excellent value
Cons: Large size, picky with memory cards
Full Review: Viofo A229 Plus Review
If you want the best deal and don’t necessarily need 4K video, check out the Viofo A229 Plus. At around $200, it is notably cheaper than the other devices listed above, and its video quality nearly matches the A329S. Its 2-channel version is one of the very best-selling dash cams on Amazon at this time (Dec 2025).
The form factor is similar, and like the A329S it supports quad-band GPS as well as 2.4 and 5 GHz Wi-Fi. This is Wi-Fi 5 though, so it’s only 1/3 as fast as a camera with Wi-Fi 6.
Optional extras include a CPL filter for the front camera, and a remote button that you can place near your steering wheel to lock videos comfortably without having to take your hand off the wheel.
If you’re looking for a device that delivers excellent value for money, the A229 Plus 3CH is the one you want.
