NEXPOW 4K Dash Cam Front & 1080p Rear w/ Built-in GPS Expired

You seem very knowledgeable and experienced in dash cams. Care to make any recommendations?

You guys are forgetting cheap microsd adapters and your computer is your phone. Remove the microsd from your camera and insert it into your adapter.
Plug the adapter into your phone. Copy it to your phone. They're cheap, $5+.

Motion blur is mostly caused by compression. 20FPS is plenty to see everything you could ever want to see in an accident situation unless they're going like 200MPH diagonally to the view of the camera. These cameras aren't great, but for the price they're pretty good from what I've seen of them. I'd much rather have 20FPS at lower compression than 30 or 60 at higher. Considering uncompressed 4K or even 1080P would fill up the max 128G memory card extremely quickly (not to mention needing a memory card with extremely high write speed and amazing endurance), compromises have to be made. 60FPS with higher compression is going to be worse than 20 with lower when it comes to trying to read moving license plates, see someone holding their phone while driving, etc.

I've never seen motion blur in a movie theater or blu ray, and 23-24 FPS is standard on both. If you're seeing motion blur (especially to the point you can't read a license plate in the movie) in those scenarios, something isn't set up right or the equipment is no good.

You couldn't be more wrong about motion blur in theaters. Seriously, I'm not even a film student, and this was covered in the very first, most basic videography class.

Focus, lighting, and motion blur are three elementary techniques to keep your attention on the subject of a given shot. Apparently they work so well for you that you don't even see the motion blur.

I'm sure I could be much more wrong.

The motion blur that applies in this discussion is in regard to being able to see a moving license plate or face clearly. Perhaps it should be more accurately described as ghosting or lag, which is from the compression algorithm and nothing to do with FPS.

Yes I'm sure if you're trained in what to look for, you can see examples of motion blur in a professional theatrical film. However I'd much prefer that to the weird unnatural "smooth" pan thing they used to do for a while. I think that was more evident when they converted theatrical format to home format, but I noticed it in theaters a few times, not sure if it was related to eliminating motion blur or not but it was very weird. But again, if the untrained eye doesn't notice it in theaters, and like I said definitely not to the point of obscuring letters or faces, I stand by my comment.

But I've certainly never seen a film in a theater with blocks, blurring, or ghosting that would make a license plate unreadable. Like I said, unless the car is moving 200MPH at a diagonal angle to the camera, 20FPS is going to be fine to read a license plate. Now the compression they put on top of that, who knows.

I think the whole FPS discussion here was related to using a Wyze or similar camera in your car. Those cloud cams use a ton of compression (over 99% on my Wyze cams), and that definitely makes a moving license plate completely unreadable at anything over about 5MPH. Plus the fact that you have to use your phone's hotspot just to get the thing to start recording, it makes no sense to use something like that in your car. Even this $40 crap camera will perform better.

I just got this deal in the mail from Walmart (SoCal) and I can confirm the model # is the VS100, and that it uses a USB-C connection for the power. The cigaratte lighter power cable has a USB-C port at the end of the long cable (there is no separate USB-C data only cable in the package). The front windshield mount has a USB-C connector inside it that then flushly slides the dash cam into that USB-C connector that is built in to that front windshield mount, and then there is a USB-C connector on the windshield mount as well to plug the power cable into, otherwise if you aren't using the front windshield mount (which is rotatable up and down) the dash cam itself has the USB-C port on it. It was not clear in either the Slickdeals listing if this unit had a USB-C or Mini USB port on it, which would affect if you have a hardware or ODB2 style power port to utilize with it I'm sure. There is a pry tool, and 3 or so plastic clips for routing the long cable run (front or rear, but probably mostly for the rear) to the side of your car if it can't be tucked at those few points. There is also another front windshield 3M tape that is spare in case you need to re-use the dash cam again in another car. It doesn't mention anything about "Starvis" on the box, unlike the Walmart item details, so no idea if it is upscaled 1080P to 4K on the front dash cam (I doubt it is a real 4K chip, but could be a Starvis 1, which as mentioned earlier some 1080P and 2K dash cams utilize). It says "Sensor pixels: 4mega pixels" and "Power Supply: Super Capacitor" on the box. The screen is tiny at 1.47". I figured that this info would help others that are waiting the order to arrive.

I also bought it to test. The videos are H264, AVC1, MP4 files.
Res 4K: The recorded video is 2880x2160, 25fps, 8 bits
Res 2K: The recorded video is 2560x1440, 30fps, 8 bits
Back camera is 1280x720, 30fps, 8 bits

Videos are grainy.

As you said, no mention of Starvis or sensor model on the box or user manual. I expected the front camera would not be real 4K, but I did not expect the back camera is only 720p@30fps. I am disappointed.

The GPS is said to be included, cannot be turn off, but need to use the DashGo player, which there is a link on the Walmart page. I haven't tried use that exe file, maybe only if I have a VM. I do not see separate files aside the MP4s.

The 4k dash Cam VS100 has two models: No screen with WIFI / 1.47 IPS screen without WIFI according to the OEM manufacturer. They claimed the cam used the sensor (GC4653 or Sony335). How to determine its sensor? probably the best way is to test it at night.
