I wanted a dash cam that could capture clear evidence from both the front and rear of my car, especially for tricky situations like parking lot dings or sudden stops. The TERUNSOUl 4K+4K Dash Cam promised exactly that with its dual-channel 4K recording and a generous 170° wide-angle lens.
This setup is perfect for drivers who want high-resolution footage without the hassle of buying a memory card separately. It stands out with its fast 5.8GHz WiFi for easy video downloads, though you’ll need to buy a separate kit for the full 24-hour parking mode. Here’s what I found after installing and using it on my daily drives.

What Stands Out — Key Features
- Dual 4K Recording: Both the front and rear cameras capture footage in 3840x2160P resolution. I found the detail was excellent for reading license plates and seeing road signs clearly.
- Free 128GB Card & High Capacity: It comes with a pre-installed 128GB memory card, so you can start recording right away. I liked that it supports cards up to 512GB for extended loop recording.
- 5.8GHz WiFi & App Control: The dual-band WiFi, especially the 5.8GHz, made downloading videos to my phone via the TERUNSOUl app very fast compared to older 2.4GHz models I’ve used.
- Built-in GPS: This logs your route, speed, and location directly onto the video. It’s useful evidence and you can view the data on the 3-inch screen or in the playback software.
- Wide 170° Field of View: The front camera’s ultra-wide angle gave me a complete view of multi-lane roads. It really does help capture more of the scene in front of you.
- Parking Monitoring Modes: It offers time-lapse and impact-triggered recording when parked. A major note: you must buy a separate hardwire kit to enable these 24-hour features.
- Complete Installation Kit: The box includes everything: a long 21ft rear cable, cable clips, a trim tool, and even electrostatic films. This made hiding the wires much easier for a clean look.
- Starlight Night Vision: With an F1.5 aperture on the front lens, it pulls in more light. Night footage was clearer and more usable than on my old dash cam.

Pros & Cons — The Honest Take
✅ What I Like
- The included 128GB memory card is a huge value and means you can start recording the moment you open the box.
- True dual 4K recording from both cameras provides incredibly sharp footage for evidence.
- The 5.8GHz WiFi makes downloading videos to my phone via the app surprisingly fast and easy.
- The installation kit is complete, with a long 21ft rear cable and tools to hide wires for a clean setup.
- The built-in GPS logs speed and route directly onto the video, which is great for verifying details after an incident.
❌ What Could Be Better
- The advertised 24-hour parking mode requires a separate hardwire kit you have to buy, which isn’t made clear upfront.
- The power cable is USB-C, so if your car only has older USB-A ports, you’ll need to buy an adapter cable.
For me, the pros heavily outweigh the cons, especially the ready-to-use package and video quality. Just go in knowing that full parking mode is an extra purchase, not a plug-and-play feature.
⚖️ How Does It Compare?
I compared the TERUNSOUl D016 to other popular dash cams to see where it really fits. I picked the ROVE R2-4K as a direct high-res competitor and the Avylet as a more budget-friendly option to see what you might give up.

🔵 Alternative 1: ROVE R2-4K DUAL Dash
Best for: Drivers who prioritize a well-known brand name and a very compact, discreet design.
Key specs: Dual 4K recording, Built-in WiFi & GPS, 150° front lens, check listing for included card size.
Where it beats the main product: It often comes bundled with a hardwire kit in some packages, making parking mode setup simpler.
Where it falls short: It doesn’t include a memory card by default, and its front field of view is a narrower 150° compared to TERUNSOUl’s 170°.

⚪ Alternative 2: Avylet Dash Cam 2K
Best for: Budget-focused buyers who want basic front-and-rear coverage without needing the highest resolution.
Key specs: Front 2K + Rear 1080p recording, Built-in WiFi, 170° front lens, check listing for included accessories.
Where it beats the main product: It’s typically more affordable, making it a good entry point for dual-camera setups.
Where it falls short: The video resolution is significantly lower, and it lacks built-in GPS for logging speed and route data.
If your main goal is getting a complete, high-quality kit with the 128GB card and 170° view ready to go, the TERUNSOUl is my pick. I’d only choose the ROVE if you find a bundle with a hardwire kit at a great price. Go for the Avylet if 2K/1080p footage is enough and you want to spend less upfront.
How It Actually Performs
Video Quality & Clarity
The dual 4K recording at 3840x2160P is the real deal. I could easily read license plates and street signs in my footage, which is the whole point. The 170° wide-angle lens on the front camera does capture a huge swath of the road, living up to the claim of covering six lanes. Night vision with the F1.5 aperture was decent, but very dark, unlit areas still showed some grain.
WiFi & App Connectivity
This is where the 5.8GHz WiFi shines. Downloading a one-minute 4K clip to my phone via the TERUNSOUl app took about 30 seconds, which is much faster than older 2.4GHz dash cams I’ve used. The app itself is straightforward for viewing and managing files, though the live preview can be a bit laggy. It’s great for quickly grabbing evidence without pulling the card.
GPS & Data Logging
The built-in GPS works accurately. I liked seeing my live speed and a compass on the 3-inch IPS screen. More importantly, it embeds your route, location, and speed directly into the video file. Using the free GPS Player on my computer to replay a trip with the data overlay felt very professional and would be solid evidence.
Parking Mode & Power
This is the most important caveat. While the camera has the software for 24-hour time-lapse and impact detection, it does not come with the needed hardwire kit. You must buy that separately to enable parking mode. Using just the included car charger, it only records when the engine is on. This is a significant extra step and cost to get the full feature.
Who Should Buy This Dash Cam?
Not every dash cam is right for every driver. Based on my time with it, here’s who will get the most out of this model and who should probably keep looking.
✅ This Is a Great Fit If You…
- Want a complete, ready-to-record kit right out of the box, thanks to the included 128GB memory card.
- Demand the highest resolution evidence with true front and rear 4K recording at 3840x2160P.
- Value fast, easy access to footage via your phone, thanks to the 5.8GHz WiFi and app.
- Want built-in GPS to log your speed and route directly onto videos for extra verification.
❌ You Might Want to Look Elsewhere If…
- You need true 24/7 parking monitoring and don’t want to buy and install a separate hardwire kit.
- Your car only has old USB-A ports and you don’t want to deal with finding an adapter cable.
- You’re on a very tight budget and are okay with lower resolution than 4K to save money.
My top recommendation is for the driver who wants a no-fuss, high-evidence setup. The TERUNSOUl 4K+4K Dash Cam delivers exceptional video quality and includes almost everything you need, as long as you understand the parking mode limitation.

Common Issues & Fixes
I ran into a couple of small snags during setup and use. Here are the solutions I found that worked.
WiFi Won’t Connect to Phone
The problem: The dash cam’s WiFi network doesn’t show up in your phone’s list, or the app can’t connect.
My fix: Make sure you’re within a few feet of the camera. Go into your phone’s WiFi settings and manually select the network named something like “TERUNSOUL_XXXX”. The password is usually 12345678.
Rear Camera Not Displaying
The problem: The screen only shows the front view, or says “No Signal” for the rear camera.
My fix: First, check that the long 21ft rear cable is firmly plugged into both the main unit and the rear camera. The connection points are small and can easily be partially unplugged during installation.
Video Files Seem Corrupted
The problem: You can’t play a recorded video file on your computer or it appears choppy.
My fix: The camera records in the MOV format. Try using VLC Media Player, which handles the files well. Also, format the memory card in the camera’s settings menu every few months to prevent file errors.
Parking Mode Not Working
The problem: The dash cam turns off completely when you park and turn off the car.
My fix: This isn’t a bug—it’s by design. Parking mode only works with a separate hardwire kit connected to your car’s fuse box. The included cigarette lighter cable does not provide constant power.
Warranty & Support
TERUNSOUl offers an 18-month warranty and lifetime technical support. I found their customer service responsive via the contact info in the manual. For warranty claims, you’ll likely need your Amazon order details, so keep that info handy.

Frequently Asked Questions
Does it really come with a memory card?
Yes, it absolutely does. The package includes a pre-installed 128GB microSD card, which is a huge convenience. You can start recording the moment you plug it in. It also supports cards up to 512GB if you need even more storage for long trips.
Can I use the parking mode feature right away?
No, you can’t. This is the biggest thing to understand. The camera has the software for 24-hour time-lapse and impact recording, but it requires constant power from your car’s fuse box. You must purchase and install a separate hardwire kit, which is not included.
How is the video quality at night?
It’s good, but not magic. The F1.5 large aperture on the front lens lets in more light, so well-lit streets look clear. In very dark areas, the footage can get grainy, but license plates from nearby cars are usually still readable, which is what matters most for evidence.
Do I need to leave my phone connected to the dash cam’s WiFi to use it?
Only if you’re actively using the app to view live footage or download videos. The camera records independently to the memory card all the time. I only connect my phone when I need to grab a specific clip, which is a great value for beginners who want easy sharing.
What’s the benefit of the built-in GPS?
The GPS logs your exact driving route, speed, and location directly onto the video file. You can see your live speed on the 3-inch screen while driving. Later, you can play back the video on your computer with a map overlay, which is incredibly strong evidence for insurance claims.
Is the rear camera cable long enough for an SUV or truck?
In most cases, yes. The included rear camera extension cable is 21 feet long. I was able to route it around the interior trim of my midsize SUV with plenty of cable to spare. For very large vehicles like full-size trucks, you might need to be strategic with the routing.
My Final Verdict
After testing it, I think the TERUNSOUl D016 is a fantastic all-in-one evidence kit. The dual 4K video is sharp, the included 128GB card is a major perk, and the 5.8GHz WiFi makes file transfer a breeze. I’d strongly recommend it to any driver who wants high-resolution front and rear coverage without hunting for extra parts. I would not recommend it to someone who needs full parking mode functionality immediately and isn’t willing to buy a separate hardwire kit.
The requirement for an extra purchase to enable parking mode is a real drawback. However, for the incredible video clarity and the complete package you get in the box, I believe it’s a worthwhile trade-off. The quality of the 4K footage alone makes it a top contender in its category for me.
Ready to Check the Price?
If you’re looking for a dash cam that delivers excellent 4K evidence and includes almost everything you need to start, this one is definitely worth a closer look.
