There’s a lot to like
But unfortunately, there’s also something that I don’t like. More about that nit-pick later.This dash cam really does have a lot of great features. I like the built-in GPS that records where events occurred. While visual indications might be sufficient under normal circumstances, it’s possible that an incident at night or in the middle of nowhere with no real landmarks in sight could present a problem. The GPS provides proof-positive of where an event occurred.I like the big bright screen on this device. I also like that the indicia for the control buttons along the bottom of the unit are ever-present at the rear of the device, so that you can quickly see what button does what, without craning your head around to view the buttons on the bottom (because that’s not dangerous at all ).I love that the rear camera is both powered and communicated with a single USB-C cable from the main unit. I’m so glad to not have to use (somewhat) non-standard cables to get that job done. It makes the install much more versatile for future modification (read as – swapping out main unit or rear camera or both without running a new cable through the head-liner).Speaking of modification, I think I’ll insert my nit-pick here: This device can’t communicate with a USB-PD, so if you plug it in to a USB-PD power source, it gets absolutely no power. Now, most things say that you have to use their power supply (as does this – but did it say that in the ad before I bought it? No, I don’t think so), but it’s only rarely nowadays that you really have to. On this device, you must use an old-fashioned USB-A power output. Why is that important to me? Because I already had a cable with a USB-C terminal installed up through the dash, A-pillar, head-liner, and out at the rearview mirror that I wanted to use, and it’s wired into a USB-PD power supply. So, it doesn’t work for this unit. Could I change the power supply that I have hard-wired inside the dash to a USB-A? Sure I could. At the investment of some amount of time and money that I would have preferred not to expend. A different dash cam might be an easier solution for me, quite frankly.So, to carry on with what I love – the suction cup mount is super strong. Companies are getting better and better with their materials and design for this. In the old days they didn’t really work so great. Combined with the fact that this device isn’t very heavy, the entire assembly stays on the windshield very reliably.This is a small thing, but the device was packaged by the manufacturer really well. Such quality and care in the packaging gave me a warm fuzzy that the device was perhaps manufactured with the same quality and care. All of the cables that came with it are heavy-duty and well-made.There are four metal contacts between the mount and the device. Why? What are they for? I’ve included a picture of those contacts. Turns out, the GPS antenna is in the windshield mount. Don’t break or lose it.I also dropped in a picture of the screen, which I think has great resolution. It’s really reflective, though, which you can also see in this picture. I think that all auto products should have mat-surface screens. If this device stays in my car for any length of time, I’ll add a mat screen protector to it to cut down on the glare.So, all-in-all, it’s a pretty great unit. If you can live with the USB-A power source kerfuffle, then maybe this is the dash cam for you. Only almost recommended – even with a five-star rating.

Excellent car-camera system that is feature-rich and installs easily in minutes.
This is one of the nicest car-camera systems I’ve tested. There are no cheap components here, with each piece feeling solidly built. You have a front camera, which is powered by a cigarette lighter adapter. This adapter has a USB-A port so that you can still charge your phone though it. The rear camera in turn is powered by the front camera, and there’s an included length of cable that you must run between the two, along with a tool to help you hide the cable under your car’s interior paneling. I skipped installation of the rear camera for now. The rear camera mounts using an adhesive pad so that you can place it above or onto your rear window. The front camera mounts using a suction cup placed on the interior of windshield.I like the front camera has icons below the display, which correspond to buttons on the bottom of the camera. This way you know which button is the menu and which does a quick image or video capture. The front camera also has a slot for a microSD card with 128GB of memory. The feed loops and is erased unless an impact is detected or you manually save a segment of video. You can either access the video by transferring the SD card to a computer or go the simple route and create a Wi-Fi connection to the camera with your phone. The menu is very intuitive to navigate, and I was able to immediately change some settings without reading the manual. For instance, I prefer front cameras to go into screen saver mode, which is not the default with this camera. A few clicks later I had set the screen to turn off after 60 seconds of being powered on. It was very easy.This is an extremely nice camera system for your car. It’s well-made, has tons of features and is very easy to set up and use. I highly recommend this, as it’s probably the best car camera system I’ve used.
