TERUNSOUL 4K 3 Channel Dash Cam Review: Triple Coverage Without the Premium Price

Somebody backs into you in a parking lot and drives off, and suddenly it’s your word against theirs. That’s the moment a dash cam either earns its keep or turns out to be a blurry smear where a license plate used to be. I put the TERUNSOUL 4K 3 Channel Dash Cam, sold as the D018, through its paces to find out which one it is.

For around $95, this triple-channel setup records 4K out the front plus 1080p from both a cabin camera and a separate rear camera. That combination pushes coverage to nearly 360 degrees around the car, and it ships with a 128GB microSD card already installed. Built-in GPS, dual-band WiFi, and a free app round out a feature list that runs longer than most cameras at this price.

I went through the on-camera menus, the phone app, the night-vision hardware, and the GPS logging to see where it delivers and where it cuts corners. Here’s the full breakdown.

What I Liked About the TERUNSOUL 4K 3 Channel Dash Cam

Sharp 4K Front Footage That Reads License Plates

The front camera records true 4K, and in practice that resolution is the line between usable evidence and a guess. In decent light you can zoom into the footage and actually read a plate off a passing car, which is the entire point of a dash cam. A 1080p front camera looks fine until the one moment you need detail, and this one holds up when that moment arrives.

Near 360-Degree Three-Channel Coverage

Three cameras run at once: a 170-degree front lens plus 165-degree rear and cabin views. Together they wrap coverage around almost the whole car, so you catch the lanes beside you and not just what sits dead ahead. Each channel saves as its own separate file, which makes handing a single angle to your insurer far simpler than digging through one stitched-together clip.

Built-In GPS With a Bonus Vehicle Locator

The GPS bakes your route, speed, location, compass heading, and timestamp straight into the video file. If anyone disputes how fast you were going or where something happened, it’s stamped into the footage rather than left to argument. The part I didn’t expect: the camera holds a location fix even when your phone isn’t connected, so it doubles as a basic vehicle locator you didn’t pay extra for.

A Free App and Fast 5.8GHz WiFi Transfers

The TERUNSOUL app connects over dual-band WiFi, and the 5.8GHz band moves clips at around 20MB/s. Pulling footage off the camera takes seconds, so there’s no wrestling the microSD card out and hunting for a reader. Better still, the app is free with no subscription and nothing behind a paywall, and firmware updates run wirelessly.

128GB Card Included, With Room for 512GB

The 128GB microSD card comes pre-installed, a genuine cost saver since most cameras make it a separate purchase. Loop recording overwrites the oldest footage automatically once the card fills, and the collision sensor locks impact clips so they survive the loop. If you rack up long days on the road, the slot accepts cards up to 512GB for far more history.

Solid Build Quality and a Heavy-Duty Hinge

The unit feels sturdier than most cameras in its price range, with a tight metal hinge instead of a plasticky click joint. That matters more than it sounds, because a firm mount keeps road vibration from smearing your footage. Small touches add up too: adhesive mounting films protect the windshield, spare stickers are included, and the button icons line up with what’s on screen.

ADAS Safety Alerts You Don’t Usually Get

A driver-assist package is built in, covering ADAS collision warnings, blind-spot detection, and lane-departure alerts. These actually fire in use rather than sitting on the spec sheet doing nothing. It won’t replace factory safety tech, but on an older car with none of it, the alerts add a layer that wasn’t there before.

What Needs Improvement

Parking Mode Needs a Separate Hardwire Kit

The listing advertises 24-hour parking mode, but you can’t use it straight out of the box. It requires a hardwire kit that TERUNSOUL sells separately, which powers the camera while the car is off. The install into your fuse box is straightforward, but budget for the extra part if parked-car monitoring is why you’re buying.

The Mount Tilts but Won’t Swivel Left to Right

The mount adjusts up and down, yet it won’t rotate side to side. That means you need to nail your horizontal aim on the first try, because you can’t fine-tune it later without repositioning the whole bracket. It’s a minor annoyance, but one worth knowing before the adhesive sets.

No Touchscreen on the 3.16-Inch Display

The 3.16-inch IPS screen is button-driven rather than a touchscreen. In fairness, the on-screen icons line up neatly with the physical buttons, so navigation stays easy once you learn the layout. Still, if you expect to tap through menus the way pricier cameras allow, this isn’t that.

A Bigger Body That’s Hard to Hide

This is not the smallest dash cam around. The heft that makes it feel sturdy also makes it a larger unit that’s tricky to tuck fully behind the mirror. Drivers who want a camera nobody notices should look at a more compact model.

Heat and Mount Adhesion Are Budget-Cam Watch-Items

Two caveats hang over most budget 4K cameras, and buyers should keep them in mind here. High-resolution recording generates heat, and 4K dash cams are more prone to trouble in hot, sunny climates. Owners of related TERUNSOUL models also note the sticky mount can let go if you skip the electrostatic film during install, so follow the steps carefully.

How It Compares to Other 3-Channel Dash Cams

TERUNSOUL vs. Vantrue N4 Pro

The Vantrue N4 Pro is the reviewer favorite among three-channel 4K cameras and the reigning pick for nighttime image quality. It also runs about $299 and sells its microSD card separately. The TERUNSOUL undercuts it by roughly $200 and includes the card, so you trade a proven track record and top-tier night video for a far lower entry price.

TERUNSOUL vs. Wolfbox X5

The Wolfbox X5 is the value benchmark reviewers keep citing, pairing a touchscreen and a 128GB card for around $199. It carries a bigger testing pedigree and a touchscreen the TERUNSOUL lacks. But at roughly half the price with the same three-angle concept and an included card, the TERUNSOUL is the cheaper route into 4K-front, GPS-stamped coverage.

TERUNSOUL vs. IIWEY N5

If you want even more angles, the IIWEY N5 adds a fourth side camera for true 360-degree coverage and leans on a supercapacitor built for heat. The trade-off is that the N5 skips built-in GPS, which the TERUNSOUL includes and stamps into every clip. For drivers who value GPS evidence over a fourth lens, the TERUNSOUL makes the stronger case.

TERUNSOUL vs. E-YEEGER S50

The E-YEEGER S50 is a simpler, cheaper dual-channel camera at around $40, with 2.5K front video, night vision, and no app at all. It’s the pick if you want plug-and-play and don’t need a cabin camera, GPS, or WiFi. The TERUNSOUL costs more but answers with a third interior channel, GPS logging, and app transfers the S50 can’t match.

Final Verdict

The TERUNSOUL 4K 3 Channel Dash Cam earns a 4.5 out of 5. It delivers the things that matter in this category: genuine 4K front footage, three angles of coverage, GPS baked into the video, and a free app that moves clips fast.

The extras seal it. A 128GB card sits in the box, the build quality punches above the price, and the ADAS alerts add safety tech to older cars. The rough edges are real but manageable: parking mode needs a separate hardwire kit, the mount won’t swivel sideways, and the body is a little large to hide.

If you need more storage for long rideshare days, the slot takes cards up to 512GB, and a high-endurance option like the Viofo 256GB industrial microSD card is built for the constant rewriting dash cams demand. For around $95 with a card already included, this is a lot of dash cam for the money, and an easy one to recommend.
