iiwey 4K Dash Cam Front Rear with WIFI GPS, Upgraded Front 4K Rear 1080P or Single Front 4K 2160p@30fps Car Camera, 3” Touchscreen Dashboard Camera, Sony Night Vision, Parking Monitor, App Control

The media could not be loaded. Was looking for a dash cam that had forward and reverse cameras. I did a lot for research looking at nextbase and thinkware cameras.The reason for me choosing this dash cam was two foldFirstly as a driving instructor I need a camera that I could use that would allow me to show my pupils clear footage of their drive and pick up any errors they may have made with observations and positioning. The touch screen is brilliant and kept the unit small so it fitted easily between my mirror and my learners mirror - see pictures.This camera is crystal clear and images are sharp. Fabulous in normal daylight and great at low light and darkness.Secondly I need software that would connect to the dashcam immediately and show footage on my phone. The Witcam wireless app connected to my phone (android) effortlessly. This was the most important aspect of my purchase. The video clips played back quickly and I really haven't had any issues with it.Downloading the app and video to the phone is as easy as pressing a button.(As a side note the nextbase app is terrible please read the reviews.)The installation is very easy and the inclusion of the pry tool was a good touch. The cables are not very thick so easy to fit around door frame without much effort. I would mention that the gps unit is separate to the camera and the power connects to the gps unit then onwards via a shorter cable to the camera. So plan as to where you place the gps.The suction mount is short so it decreases the amount of space need to place the camera.The camera in my opinion is excellent and 4k quality is superior. The addition of the SD card was a bonus and very much appreciated, as is the power supply that has a usb port on top to charge your phone!If there is one thing I would like is for the screen saver option to have the speed and time displayed instead of a blank screen, THAT would be the icing on the cake.

I've had a lot of dashcams over the years and when I decided to upgrade I couldn't decide whether to buy this one or a different brand with a 4" screen thats also popular on Amazon.As Amazons return policy is so totally brilliant I ordered them both with the view to keep the one I preferred and return the other one.This won hands down and I absolutely love it, the touchscreen is absolutely awesome, I'd never go back to one with buttons now, this has spoilt me big time, it really is excellent.Its very clear and simple to use with impressive video quality in a nice neat well built unit that looks great and feels good, it also came with a sd card which is a very nice touch indeed.The rear camera is an afterthought and is just a genetic standard rear view camera, possibly not a bad thing as they are very popular and have stood the test of time.I've tested the rear camera but not fully installed it in the car yet so can't give it any scores on the doors at the moment.I chose this for the front camera and the rear one coming with it was just a bit of gravy that to be honest I'm not really that bothered about.GPS is NOT built into the camera and is provided via a little discrete box that has to be plugged into the camera in series with the power supply, not a biggy but worthy of a mention.I ran the recorded mp4 video files through Dashcam Viewer and the map overlay didn't work, everything else did, just not the map overlay section.To explore this a little further I wrote a script using exiftool that automatically rips the gps coordinates from the recorded mp4 video files and outputs them to GPX format, after viewing the GPX files the coordinates it produced were sheer nonsense.After a number of hours wasted in front of the pc headshaking and shouting it appears the reason for the coordinate output error is because of the encryption the camera uses to store the gps data using some yet unknown/unhacked encryption scheme.Whether this will change in the future and map overlays will eventually work is anyones guess, but at the moment they don't.All in all I'm impressed and will be buying another one for my 2nd car, I highly recommend it.
