You are driving home late at night, and a car swerves into your lane. Without a 3 channel dash cam, you might miss the incident entirely. A 3 channel system records the front, the cabin, and the rear simultaneously, giving you complete evidence of any event on the road. Whether you drive for Uber, Lyft, or simply want peace of mind for your family, a 3 channel dash cam is a smart investment. In this guide, we evaluate three top models from TERUNSOUl, CURRENBA, and 70mai to help you find the best fit for your needs.
We have assessed these dash cams based on video quality, night vision, parking monitoring, and ease of use. Each product was reviewed for real-world performance, not just specifications. Below, you will find a direct comparison table followed by a detailed buying guide and our final recommendations.
Pros
- True 4K resolution on both front and rear cameras for exceptionally clear footage.
- Included 128GB card provides immediate value, with support for up to 512GB.
- Advanced night vision with IR lights ensures cabin visibility in pitch black.
- WiFi 6 and app make video access and settings adjustments quick and convenient.
- Built-in GPS adds an extra layer of detail to your recordings.
Cons
- Hardwire kit required for 24-hour parking monitoring, sold separately.
- Cabin camera resolution is 1080P while front and rear are 4K, which may be a consideration for some users.

The TERUNSOUL 3 Channel Dash Cam is a comprehensive recording solution designed for drivers who want no blind spots and crystal-clear evidence. It is particularly well-suited for rideshare drivers, fleet operators, and anyone who commutes at night or parks in unsecured areas. With 4K front and rear cameras plus a 1080P cabin view, it captures every angle of your journey.
What sets this dash cam apart is its AProX HD Night Vision technology. The cabin camera includes four IR LEDs that illuminate the interior without glare, delivering usable footage even in complete darkness. Combined with WDR (Wide Dynamic Range), the system handles challenging lighting conditions like tunnels or oncoming headlights with impressive clarity.
Installation is straightforward, and the 3.18-inch full-laminated screen reduces reflections for easy menu navigation. The included 128GB memory card is a generous bonus, and loop recording ensures you never run out of space. The built-in GPS logs your speed and route, adding an extra layer of security for your records.
One potential drawback is that the parking monitoring feature requires a separate hardwire kit, which adds to the total cost. Additionally, while the front and rear cameras shoot in 4K, the cabin camera is limited to 1080P, which may be a minor letdown for those wanting uniform resolution across all channels.
Overall, the TERUNSOUL 3 Channel Dash Cam offers a compelling mix of high-resolution recording, robust night vision, and user-friendly features at a competitive price. With a 3-year warranty and 24/7 support, it is a reliable choice for anyone serious about dash cam security.

Buying Guide: What to Look for in a 3 Channel Dash Cam
Video Resolution and Coverage
For a 3 channel dash cam, resolution matters most for the front camera. A 4K front camera captures license plates and road signs clearly, even at highway speeds. Rear and cabin cameras should be at least 1080p to provide useful detail. The TERUNSOUl model offers 4K+4K+1080P, while the 70mai and CURRENBA options provide 4K front with 1080p interior and rear. Choose based on how much detail you need in each direction.
Wide viewing angles reduce blind spots. Look for front angles of 170 degrees or more. Rear and cabin angles around 150 degrees are standard. For rideshare drivers, a cabin camera with infrared (IR) LEDs is essential for clear interior footage at night.
Night Vision and Low-Light Performance
Driving after dark is common, so night vision is a critical feature. Advanced HD night vision with WDR (Wide Dynamic Range) helps balance bright headlights and dark shadows. Models with IR LEDs for the cabin camera, like the TERUNSOUl and CURRENBA, ensure you can see passengers clearly in complete darkness. The 70mai dash cam uses HDR and 3D noise reduction for sharp night footage. Always check sample footage if possible.
If you frequently drive in low-light areas, prioritize a dash cam with a large aperture (F1.6 or lower) and proven night vision technology. This is especially important for rideshare drivers who rely on cabin footage for safety.
Parking Monitoring and Storage
Parking monitoring is a valuable feature that records incidents when your car is parked. Most systems offer time-lapse or collision detection modes. Note that parking monitoring usually requires a separate hardwire kit. The TERUNSOUl and CURRENBA models include this feature, while the 70mai also supports it with a hardwire kit. Built-in storage is convenient; the TERUNSOUl comes with a free 128GB card, the 70mai includes a 64GB card, and the CURRENBA includes a 64GB card. All support expansion up to 512GB.
Loop recording ensures the dash cam never stops recording by overwriting old footage. G-sensor emergency lock protects important clips from being overwritten. These features are standard on all three models we reviewed.
Connectivity and App Support
Modern dash cams offer WiFi for easy file transfer and app control. Dual-band WiFi 6 (5.8GHz + 2.4GHz) provides faster speeds, as seen on the TERUNSOUl and 70mai models. The CURRENBA supports dual-band 5GHz WiFi. App features vary: the TERUNSOUl app supports OTA updates, while the 70mai app offers voice control and 5-mode GPS. Built-in GPS records speed and location, which is useful for insurance claims or route reviews. Choose a model with an app that matches your preference for ease of use and feature set.

Final Thoughts
After reviewing these three 3 channel dash cams, our top recommendation is the 4K+4K+1080P 3 Channel Dash Cam, Free 128GB Card from TERUNSOUl for its exceptional 4K+4K front and rear resolution, generous 128GB included storage, and advanced night vision with IR cabin lighting, making it ideal for rideshare drivers and night commuters. For a budget-friendly option with solid 4-channel coverage, the 4 Channel 360° Dash Cam Front and Rear Inside from CURRENBA offers four lenses and a 64GB card at a lower price point, perfect for drivers who want maximum blind-spot elimination without breaking the bank. Both models provide reliable parking monitoring and easy app control, ensuring you are covered whether you are on the road or parked.

Frequently Asked Questions
What is a 3 channel dash cam?
A 3 channel dash cam records video from three cameras: one facing the front windshield, one facing the rear window, and one facing the cabin interior. This provides complete coverage of your vehicle, helping you capture events from all angles, such as accidents, theft, or passenger incidents.
Do I need a 3 channel dash cam for rideshare driving?
Yes, if you drive for Uber, Lyft, or any rideshare service, a 3 channel dash cam is highly recommended. The cabin camera records passenger behavior, while the front and rear cameras capture road incidents. This can help resolve disputes and provide evidence in case of accidents or false claims. Many rideshare drivers prefer models with infrared cabin cameras for clear night recordings.
How much storage do I need for a 3 channel dash cam?
Storage depends on video resolution and recording time. A 128GB card can store several hours of 4K footage from all three channels before loop recording overwrites old clips. Most dash cams support cards up to 512GB. We recommend at least 128GB for daily use, especially if you drive long hours. The TERUNSOUl model includes a 128GB card, while the 70mai and CURRENBA include 64GB cards, which is sufficient for shorter commutes.
Can a 3 channel dash cam record while parked?
Yes, many 3 channel dash cams offer parking monitoring mode. This feature uses a hardwire kit to keep the camera powered when the engine is off. It can record in time-lapse mode or trigger recording when motion or impact is detected. This is useful for protecting your vehicle in parking lots or on the street. Check the product specifications to confirm parking monitoring support and required accessories.
