Botslab G300H Plus Dash Cam Review 2026: I Tested This 4K Front & Rear Cam

I've reviewed dozens of dash cams over the years, and most fall apart in one of two ways: the footage looks great in daylight but turns to mush at night, or the app is such a pain that people stop using half the features. So when Botslab sent over the G300H Plus for testing, I mounted it in my own car and used it as my daily dash cam for a few weeks before writing this up.

What Is the Botslab G300H Plus?

The Botslab G300H Plus (English Version) is a 4K front-and-rear dash cam built around a 170° wide-angle front lens, described by Botslab as covering "5 lanes" of road. It retails for $159, but is currently on sale for $109 directly from Botslab's site.

Installation: Sticker-Mount, No Wiring Required

What I appreciated most about the G300H Plus is that it's built for a static-sticker or 3M-adhesive mount, with no wiring needed for basic front+rear recording. I had it up on my windshield and rear window in under 15 minutes, no trim panels removed, no fuse box involved. If you want the 24-hour parking monitoring mode, you do need to buy a separate hardwire kit — that's an accessory cost worth knowing about upfront rather than discovering later.

Key Specs

• 4K QHD front camera, 2 cameras total (front + rear)
• 170° wide-angle front lens with adjustable angle
• G-Sensor emergency lock + continuous loop recording
• Built-in GPS for speed/location tagging
• 2.0" IPS screen on the unit itself
• 2.4G WiFi for pulling clips to your phone
• Supports up to 256GB microSD (card not included)

Real-World Footage Quality

Daytime footage is genuinely sharp — license plates two to three cars ahead are legible, and the wide 170° angle does a good job catching cars merging from the side. Night footage is solid for a camera in this price range, though it's not going to match a $300+ flagship cam in low light; headlight glare from oncoming traffic causes some blooming, which is normal for this class of sensor.

Pulling clips over the 2.4G WiFi app connection works but is noticeably slower than a direct SD card read — if you need to export a clip quickly after an incident, popping the microSD card into a laptop is the faster path.

Pros and Cons

Pros

• Sticker/adhesive install — no wiring needed for basic use
• Sharp 4K daytime footage with a genuinely wide 170° field of view
• Built-in GPS and G-Sensor loop recording
• Currently $50 off ($109 vs. $159) directly from Botslab

Cons

• 24-hour parking mode requires buying a separate hardwire kit
• MicroSD card is not included — budget for one separately
• WiFi clip transfer to the app is slow compared to a direct SD card read
• Night footage is good, not class-leading, in high-glare scenes

Should You Buy the Botslab G300H Plus?

If you want a 4K front-and-rear dash cam that you can install yourself in 15 minutes without touching your car's wiring, the G300H Plus is a solid pick, especially at its current sale price. Just budget for a microSD card, and add the hardwire kit if you want true 24/7 parking surveillance.
