TERUNSOUL D018D 3 Channel Dash Cam

Updated October 22, 2026. Based on the Amazon listing and owner reviews, not a hands-on test.

Quick verdict: This TERUNSOUl D018D is a three-channel dash cam for rideshare drivers and anyone who wants the road ahead, the road behind, and the cabin all on record. Its main strength is the spec sheet: 4K front, 4K rear, a 1080P infrared cabin camera, GPS, and dual-band WiFi 6 in one kit. The main catch is that 24-hour parking monitoring needs a hardwire kit that is not in the box, and three cameras mean more wiring than a simple windshield unit.

Who should buy it (and who should skip it)

Good fit if you

• Drive for Uber, Lyft, or a delivery service and want a record of what happens inside the car as well as on the road.
• Want 4K on both the front and rear cameras instead of the more common 4K front with a lower-resolution rear.
• Prefer pulling clips to your phone over WiFi instead of removing the memory card.
• Like having speed and location stamped into your footage through built-in GPS.

Probably skip it if you

• Only want a small, single-lens camera that disappears behind the mirror.
• Are not comfortable routing a long cable to the rear window, or paying someone to do it.
• Need parking surveillance right away but do not want to buy and install a separate hardwire kit.
• Would rather not have an interior camera pointed at passengers.

Key specs at a glance

What it does well

Full coverage from three cameras

Most dash cams in this class cover the front and maybe the rear. This kit adds a cabin camera, so a single unit records the road ahead, the view out the back, and what happens inside. For rideshare drivers, that interior view is often the main reason to buy a three-channel camera at all, since it can document passenger disputes.

The wide angles help too. A 170° front lens catches more of the lanes beside you, and the 150° rear and cabin lenses cover most of the back window and the seating area.

4K on the rear, not just the front

Many front-and-rear systems drop the rear camera to 1080P or 2K. Here the listing claims 4K for both the front and rear, which matters when you need to read the plate of a car that hits you from behind. Keep in mind that the listed frame rate is 25 fps, which is normal for multi-channel 4K but lower than the 30 fps some single-channel cameras offer.

Night recording inside and out

The listing pairs an f/1.5 aperture with WDR and what the brand calls AProX HD Night Vision. A wide aperture lets in more light, and WDR helps balance bright headlights against dark surroundings. The cabin camera has 4 IR lights, so it can record the interior even in complete darkness, which is exactly when rideshare incidents tend to happen.

Fast WiFi 6 and app control

Transferring 4K files over old 2.4GHz WiFi can be painfully slow. This model supports dual-band WiFi 6 with a 5.8GHz band and quotes transfer speeds up to 20MB/s. Through the TERUNSOUL app you can preview, download, and share clips, change camera settings, and install OTA firmware updates without pulling the card.

GPS, loop recording, and a usable kit

Built-in GPS writes speed and location into the footage, which adds useful context for insurance claims. Loop recording overwrites old files automatically, while the G-sensor locks clips when it detects an impact so they are not lost.

The box is also well stocked. You get a 128GB card, a long 21ft rear cable, an 11ft USB-C charger with a spare USB-A port, cable clips, and a trim tool for tucking wires under the headliner. Overall feedback on the listing leans clearly positive across a moderate number of reviews.

Common complaints and limitations

The review text in our data sample was not available, so the points below come from the listing details and from issues that are common with three-channel dash cams of this type. Read recent low-star reviews on the listing before you buy.

• Parking mode is not plug-and-play. The listing states that 24H parking monitoring requires a hardwire kit, and none appears in the included components. Budget for one, plus installation if you do not wire it yourself.
• Installation takes time. Three cameras and a 21ft rear cable mean routing wire along the headliner and pillars. It is doable with the trim tool, but it is not a five-minute job.
• Suction cup mounting. The kit uses a suction cup mount. These can loosen in extreme heat or cold, so check it periodically, especially in summer.
• Heavy storage use. Two 4K streams plus a 1080P stream fill a card quickly. The 128GB card will loop faster than many buyers expect, so consider a larger card if you want more history.
• 25 fps frame rate. Fine for most incidents, but fast-moving details like plates on passing cars can blur more than on higher frame rate cameras.
• Privacy considerations. An interior camera that records passengers may require you to inform riders, depending on your state and platform rules. Check before you start driving with it.
• Bluetooth is listed but not explained. The specs mention Bluetooth, yet the bullets only describe WiFi features, so do not buy it for a Bluetooth-specific function.

Setup and everyday use

1. Format the card first. Even though a card is included, format it in the camera before the first drive. Reformat every few weeks to keep files healthy.
2. Test fit before mounting. Power the camera with the car charger and check the live view on the 3.18" screen. Place the front unit behind the rearview mirror so it stays out of your line of sight.
3. Use the electrostatic films. Stick the film on clean glass and mount onto it. This makes removal easier later and protects window tint.
4. Route the rear cable carefully. Tuck the 21ft cable along the headliner, down the pillar trim, and to the rear window using the clips and trim tool. Keep it clear of side curtain airbags.
5. Aim the cabin camera. Check that it covers both the front and rear seats, and confirm the IR image at night.
6. Connect the app and update. Pair the TERUNSOUL app over WiFi and check for firmware updates before relying on the camera.
7. Tune the G-sensor. If rough roads trigger too many locked clips, lower the sensitivity so the card does not fill with protected files.
8. Plan parking mode. If you want time-lapse or collision monitoring while parked, buy a compatible hardwire kit or have it professionally installed.

How it compares

Against a two-channel model like the 70mai A810 Lite 4K Dash Cam Front and Rear, the main difference is the cabin camera. If you never carry passengers for work, a front-and-rear setup is simpler to install and leaves less wiring to hide. If you drive for a rideshare service, the TERUNSOUl's infrared interior view is the reason to choose it.

Compared with a basic Front 4K + Rear 4K Dual Dash Cam, this kit adds the cabin channel while keeping 4K at the rear, and it bundles GPS, WiFi 6, and a 128GB card. The trade-off is more cables, more storage use, and a more involved install. Pick the dual camera if you value simplicity, and pick this one if full coverage matters more.

Frequently asked questions

Does the TERUNSOUl D018D record inside the car?

Yes. It has a 1080P cabin camera with a 150° view and 4 IR lights, so it can record the interior even in complete darkness.

Does parking mode work out of the box?

No. The listing says 24H parking monitoring, including time-lapse and collision detection, requires a hardwire kit. A hardwire kit is not listed among the included components.

What memory card does it use?

It uses a microSD card. A 128GB card is included, and the camera supports cards up to 512GB in its single slot.

Can I download videos to my phone?

Yes. The TERUNSOUL app for iOS and Android connects over dual-band WiFi 6 and lets you view, download, and share footage, change settings, and install firmware updates.

Does it record speed and location?

Yes. The built-in GPS records driving speed and location data into the videos.

What guarantee does it come with?

The listing mentions a 3-year guarantee and 24/7 customer support from Terunsoul. Check the listing for current terms before you buy.

Bottom line

The TERUNSOUl D018D packs a lot into one kit: 4K front and rear, an infrared cabin camera, GPS, fast WiFi 6, and a 128GB card. It suits rideshare drivers and anyone who wants full coverage of the road and the interior. Go in knowing that installation takes some effort, the storage fills quickly, and parking mode needs a hardwire kit bought separately. If those trade-offs work for you, check the current price and recent reviews on Amazon.
