This is my top pick because it’s the only one here that records true 4K on both the front and rear cameras.

This dash cam stands out for its smart features, not just its video. It uses a high-end IMX415 sensor for excellent low-light clarity and adds ADAS safety alerts for lane departure and forward collisions. I like that it specifies a 150° angle for the rear camera, giving you a clear view. It’s the best choice for drivers who want an extra layer of safety assistance and great image quality from a known sensor. The main drawback is that you need to buy a memory card separately.
✅ Pros
- High-quality IMX415 STARVIS sensor for night vision
- Includes ADAS driver safety alerts
- Clear 150° wide-angle for the rear camera
- Also features 5.8GHz WiFi
❌ Cons
- Does not include a memory card
- Rear camera is 2K, not 4K
- Smaller 2.45″ screen

If your main goal is getting a reliable dash cam with all the essentials for the lowest cost, this is it. It includes a 128GB card and a Sony STARVIS sensor for good night performance, which is rare at this price. The 3″ screen is nice for quick playback. It’s ideal for budget-conscious drivers who still want a card included and solid 4K front video. The compromise is on the rear camera, which only records in 1080P, and the WiFi is 5GHz instead of the faster 5.8GHz.
✅ Pros
- Great value, includes a 128GB memory card
- Features a Sony STARVIS sensor for night vision
- Full 3″ IPS display for easy viewing
- Competitively priced
❌ Cons
- Rear camera is only 1080P resolution
- WiFi is 5GHz, not the faster 5.8GHz
- Lower max storage support (256GB)
Which One Should You Buy?
After testing the specs, I can tell you there’s no single winner for everyone. Your best choice depends on whether you prioritize video quality, smart features, or saving money.
TERUNSOUl 4K+4K Dash Cam Front and Rear is right for you if…
- You want the absolute highest video detail from both cameras for evidence.
- You don’t want to buy anything extra—it includes a 128GB card.
- You download clips often and need the fastest 5.8GHz WiFi speed.
BOTSLAB 4K Dash Cam Front and Rear is right for you if…
- You want extra safety alerts like lane departure warnings (ADAS).
- You care about sensor quality and want the IMX415 for night vision.
- You already have a high-end microSD card you plan to use.
Coolcrazy 4K Dash Cam Front and Rear is right for you if…
- Your budget is tight but you still want a card included.
- You mainly care about great 4K front video and decent night vision.
- You don’t mind that the rear camera is 1080P instead of 4K or 2K.
❌ Who Should Skip All of These?
If you need professional-grade, multi-channel recording for a commercial fleet, these consumer dual cams won’t cut it. Also, if you only want a simple, single-lens dash cam for the front windshield, you can find cheaper options.
For most people looking for a great all-around mid-range dash cam, my top pick is the TERUNSOUl. It gives you the best video evidence out of the box with its dual 4K recording and included memory card.
Frequently Asked Questions
Which dash cam has the best video quality overall?
The TERUNSOUl 4K+4K has the best overall video quality because it’s the only one that records true 4K resolution on both the front and rear cameras. The BOTSLAB has a great 4K front camera with an IMX415 sensor, but its rear is only 2K. The Coolcrazy has a 4K front but its rear drops to 1080P. For pure video detail from both ends, the TERUNSOUl wins.
Is the BOTSLAB’s ADAS feature worth it over the TERUNSOUl’s 4K rear camera?
It depends on what you value more. If you want extra safety alerts like lane departure warnings, the BOTSLAB’s ADAS is a unique benefit. However, if your main goal is clear evidence, the TERUNSOUl’s 4K rear camera will capture more detail like license plates. For most people wanting a dash cam for proof, I think the higher video resolution is more valuable than the alerts.
Which dash cam is the best value for money?
The Coolcrazy 4K Dash Cam is the best value if your budget is tight. It includes a 128GB memory card and a Sony STARVIS sensor for solid night vision at a lower price point. You are compromising on the rear camera quality (1080P) and WiFi speed (5GHz vs 5.8GHz), but you get the core features you need without spending extra.
Do I need to buy a memory card separately for any of these?
Yes, but only for the BOTSLAB model. The TERUNSOUl and the Coolcrazy both come with a free 128GB memory card included in the box, so they’re ready to record right away. The BOTSLAB does not include a card, so you must factor that into its total cost.
Which one is best for night driving?
The BOTSLAB is likely the best for night driving due to its specific IMX415 STARVIS sensor, which is designed for excellent low-light performance. The Coolcrazy also has a Sony STARVIS sensor, which is good. The TERUNSOUl uses enhanced night vision technology but doesn’t specify the sensor model. For confidence in dark conditions, I’d lean toward the BOTSLAB.
Can all of these dash cams record while my car is parked?
Yes, all three support 24-hour parking mode, but they require a separate hardwire kit for your car’s fuse box to work when the ignition is off. The BOTSLAB markets its feature as “24/7 Parking Mode,” but functionally, they all offer similar protection when properly installed with the right accessory.
My Final Verdict
After comparing every spec, the TERUNSOUl 4K+4K Dash Cam is my clear overall winner. It delivers the best video evidence package with true 4K recording on both cameras, includes a 128GB card, and has the fastest 5.8GHz WiFi. The BOTSLAB is the smart choice if you really want ADAS safety alerts and its excellent IMX415 sensor, but you’ll need to buy a memory card.
If you’re still on the fence, ask yourself what you’ll use the footage for. If it’s primarily for insurance evidence, the dual 4K of the TERUNSOUl is the most future-proof and detailed choice. If you want driving aids, lean toward the BOTSLAB.
