Dash Cam Front and Rear,4K+1080P WiFi Dual Dash Camera for Cars with App, 3" IPS Dashboard Camera Recorder,Night Vision,24H/7 Parking Mode, Loop Recording,170° Wide Angle,Free 64GB SD Card

The first bit of good news is that it IS 4K, when that is selected or by default. I read a review of another dash cam that claimed 4K and it never went above 1080P, no matter the setting. I tested all three resolutions, downloaded the files, and opened in the appropriate video program that confirmed the numbers. Having said that, I really can't see any reason to go over 2K. Doing so will also make your SD card last longer.The whole setup was pretty straightforward, including obtaining and using the wifi enabled (why don't any of these cameras use bluetooth? Would be the perfect choice, no switching wifi AP's in your phone, Yes, I have wifi when on road trips via a hotspot) app. I had one email inquiry to customer service, answered reasonably promptly and well done. Besides what you expect, it comes with both suction cup and sticky tape mountings, and a short cord to the rear camera if you want to mount it to see the interior instead.The printed instruction booklet is English only (Thank you!), large, and extremely well done. Plenty of illustrations and warnings. One thing that could be confusing is their presumption that your cig lighter is live only when the engine is on. There are cars that are always on (like my current and last, two always on outlets) and cars that shut off with the ignition (like my previous last two.) So, YYMV as to powering things up or not. Logically, the parking cam functions can only run with power to the camera, so you need either a cig lighter that stays on, or the hard wire kit. The latter will shut off the camera when the car battery voltage drops to 11.7V, thus leaving enough to start your car.I did a test with both the main and rear cameras on. This camera has, in fact, two different 2K's. When you select 2K for the front camera, it is really "QHD" at 2560x1440 pixels. A very nice and functional 60% increase in surface area over standard 2K, 1920x1080 pixels. The rear camera always records in standard 2K. When it is connected, the camera records a file for each, and they are labeled F and R. Nice.I spent the better part of a day testing various options in order to find what I want. One weird thing that appears to be the way most or all dash cams are set up is that you can't just record continuously as one file until the SD card is filled. The default time is 1 minute, after which a new file is started, which results in hundreds of files for any length of operation. I set the default to 5 minutes, the maximum. Still too weird, especially if you want to make a travelogue. Of course, you can splice all your 5 minute vids into a long one with about any video editing program. NOTE THAT THERE IS NO AUTO SHUT OFF OPTION FOR WHEN THE CARD IS FULL! You will have to catch it and download content before that happens.All in all, a good purchase.G900 MEMORY & DATA USE1080p 1920X1080 =2MP80MB/MIN64GB: 13.3 HRS2k+/QHD 2560X1440 =3.7MP100MB/MIN64GB: 10.7 HRS4k 3840X2160 =8.3MP200MB/MIN64GB: 5.3 HRSFRONT AND REAR CAMERA, FRONT SET AT 2KFRONT = QHD, 2560X1440 85 MB/MINREAR = REAL 2K 1920X1080 64 MB/MIN159 MB/MIN TOTAL64GB: 6.7 HRSEDIT: Many years ago American Express ran ads saying, "Don't leave home without it." Same advice as this dashcam.Almost a year later, and if anything, I love this camera more. My original installation car died, and I wound up getting rentals for a few months. SO easy to transfer, and with rental car liabilities, could prove invaluable.I have just returned from a road trip into Mexico, and I have a days long record of that trip for my memories. Most importantly for me, it recorded my car traversing the Rio Grand via America's only hand drawn ferry! And going through US Customs with audio. Ya never know....DO GET A 256GB CARD! In fact, as cheap as memory is now I may up that. My previous advice was using a 2K setting. I now go full 4K and I still get about three days of recording, always on. The recorded videos are stunning, just like they came out of a dedicated video camera. (I should know, well versed here.)

Sadly dont have any photo's as I bought this as a gift for a friend who got a new car the end of last year. She lives in a bad neighborhood (in my opinion lol) and i just wanted her to be safe both on the road and when its parked. I bought her connections for direct battery power so she can use the parking monitor function. The functions of the camera are typical for most dashcams but the built in wifi and the voice commands are an added extra bonus for the price. Most dashcams with these functions wanna run up over the $100 limit or they are cheaper because the camera quality is of lower resolution. This dashcam has it all. High resolution recording, dual front and back cams, (the back cam is a small camera with a long enough cord that runs to connect to the main dashcam. it can be places on the back window of the car of inside or depend on the car size on the middle light console on the inside roof of the car so as to get the backseat/visual through the back window with the back sides. This mostly only works in SUV's or trucks. In a regular car I would strongly suggest it directly on the back window. Just make sure you dont place it directly over the heating grid line so it doesn't obscure the dashcam recording. )My friend loves it, loves using the mobile app and the voice commands. She's made post about it on her social media, and constantly tells me how happy she is with it. She always wanted to get one but isn't tech savy as she calls it, and was afraid she would overpay for something not worth it. She tells me she feels a lot safer now without having to worry about possible insurance scams or just in general if she were to get in a crash and see a crash this could help not just her but possible someone else while on the road. But at her apartments she doesn't worry as much about her car getting broken into. The memory card that came with the camera just made it that much easier to setup immediately without spending extra money or extra accessories. The dashcam screen itself even though the normal size is very crisp and clean looking. The color on the screen looks more vivid then human eye sight xD The night vision itself is amazing. Clear and crisp as well. You can cleary read License plates and see faces when watching back the recording both on the dashcam itself and on a computer. the app just makes it that much easier without having to directly remove the memory card. All in all this was a really good buy. The price vs the quality is still breath taking. I mean Im honestly buying another one for my car as I have an older dashcam thats like 4 years old.

This was easy to start up, it’s not easy to connect the Bluetooth to download the video to your phone and it’s a little complicated to adhere to the windshield. It’s small enough not to be in the way and the back camera is small and not in the way too. I just don’t like all the wires but they are long enough and I have mine in my Subaru Outback.Night vision is great and I think it’s worth the money. I don’t use the audio which you can turn on with a button, but I’m sure it’s fine too. I would recommend this for a quick fix to not having one in your vehicle. I got one for peace of mind and I’m glad I bought this one. Overall, it does what it says it does and it’s good quality.

After I got in a wreck that wasn’t my fault luckily I was able to get footage from the business it happened infront of Everyone I talked too inssurance and police all said I needed a dash cam I found this one and it was super easy to set up I used the suction cup mount so I didn’t damage my tint I also bought a adapter that uses the power from the rear view mirror so I didn’t have to run any wires at all. It turns on and off with the key it’s a great peace of mind knowing I have this now
