WOLFBOXUpgraded WDR Rear Camera for G840S / G840H / G930 / G850 /G850PRO, 1080P Waterproof AHD Car Rear View Camera

I admit, I was skeptical, and I was pretty happy overall with the camera bundled with my G840S. I wasn't sure what, exactly, I'd be getting for the forty bucks.I'm so glad I spent them. Seriously.First, this camera has dramatically improved glare reduction over the stock camera. At night, headlights resolve more neatly, instead of becoming pools of smeary, indistinct white light. I had no problem knowing there was a car behind me with the stock camera, but the combination of better glare mitigation and much faster white balance correction as lighting changes meant that the video capture produced useful images with less of a recalibration delay, at night. If I ever need a clear image from a half-second flyby behind me on the recorder log, this camera is much more likely to deliver it than the stock one, for that reason alone. Again, the stock camera wasn't "bad," really -- just average. This one's much, much nicer.It offers a wider field of vision, too -- and yes, that means a little fisheye effect at the extreme edges. That would be annoying, if not that this is a backup camera, and that translates to even better peripheral vision coverage. I've caught people in the parking lot waiting behind and to the side of my car that I couldn't see with the stock camera -- well out of my way, yes, so they weren't safety hazards, but being able to see them at all is a testament to the improved field of vision the upgraded camera offers.White balance and dynamic range are nicer, too, but I really only notice the difference at night. The stock camera was more than adequate during the day, and while this one's a step up, you really feel the difference more at night than in the day.Installation was a snap, as it uses the same connector as the stock camera. Unplug old, plug in new -- I believe it even mounted to the original mounting bracket, identically.If you're basically content but not thoroughly delighted with the stock G840S camera's quality, yes, definitely, buy this one. You'll be glad you did, and I'm pretty confident you'll find it a significant step up from the stock camera. It elevated the quality of my G840S to the next level, and I'm very, very happy with it.

I purchased this to pair with another brand dash cam. The rear camera that came with my dash cam had poor low light performance and bloomed out when headlights hit the camera. This camera lives up to its claim that it can clearly read a license plate number at night even with headlights shining. It was worth the few dollars more in performance.

Very good product

The rear camera I previously had was practically useless at night because of the constant lens flare and lack of self-adjusting exposure. Now with this replacement rear camera, it is a huge improvement. I can now actually determine what lane other cars are behind me are in at night while producing a great quality image, and greatly reducing lens flare. It was also pretty easy to install since it was pretty much plug and play with my existing wiring connected to my JADO rear view mirror camera.

I've been using the VanTop H612T 12" 4K Mirror Dash Cam since August 2020, primarily because I needed a better nighttime WDR rear camera. After some research, I stumbled across this model. There’s been some talk about VanTop rebranding as Wolfbox, but I bought this camera knowing it had a 4-pin connector. To my surprise, the 4-pin connector worked seamlessly with my existing cable—no need to deal with re-wiring.The main reason for the upgrade was nighttime visibility, and the camera delivered. As shown in the uploaded images, there’s no more “nighttime blowout” where headlights overwhelm the view. The WDR (Wide Dynamic Range) seems to be active at all times, or perhaps the image sensor has some extra bit-depth because the nighttime performance is far superior to my older rear camera. The only minor observation is that during the day, the clouds can appear slightly oversaturated with a bit of unnatural color tone, likely due to WDR processing. It’s a trade-off I’m happy with since critical details remain visible, and the overall image quality is still excellent.Some reviewers have mentioned that the daytime color balance is slightly saturated. To me, it looks fine. Daytime visuals remain clear, and most importantly, the camera reliably captures critical information. The trade-off is well worth it for the huge improvement in nighttime performance.The images I shared were taken straight from the video recordings, and they speak for themselves. If you’re using an older rear camera that struggles with blown-out highlights or poor visibility at night, this dash cam is a must-have upgrade. You won’t regret it.

not working for g900 pro even tho it said thats its compatible for g900 pro, for some reason device is not detecting the rear camera.

So far no complaints. Hooked up with ease

Expensive but it manage light focus very well
