I think most of mine were replaced between 1 and 2 years old (a few even sooner)
I started off with one of these in 2010
Cost around £25 - £30, at the time I was pleased with the results it provided (not knowing any better) this is a screen capture of the type of quality it produced
Notice you can’t read the road signs so no chance of reading a car registration, but at the time I was happy
My first dive in to high end dashcams came in 2013 with the Blackview @£300 odd (in 2013 a bit of money for the time) and that was a big letdown right out the box, low bitrate made the image dreadful, lucky a Russian guy had a fix for the low bitrate that made the images captured decent, but that also made the Blackview very unreliable
Then for the following few years I had a range of the Mini series and they all at one time or another had focusing issues and power connectivity, some even had the shakes as the mount between the screen mount and the Dashcam body used to vibrate so had to modify that area of the mount
Then in 2018 I bought the Viofo A129 duo, and have been pleased with it so far
For one of my other cars I have one of these dash cams
It’s an added extra with the head unit, it’s compatible with the head unit, it gets power from the head unit, can save and/or view the footage on the head unit’s large screen
Files can be saved on the micro SD of the head unit or on the SD card of the Dashcam
