Nextbase 522GW. Easy to use and good quality video. The adhesive mount allows the camera to be positioned high in the window so out of the passengers line of sight. The suction mount is larger and the camera mounts lower on the screen.
Only thing with the adhesive mount is the adhesive pad is grey and is quite prominent when you look at the windscreen from outside the car. Shame they didn't make it black instead. Other than that, really pleased with the setup.
You can get over the grey tape by using black d/s tape of the type they use to stick on spoilers and trims. I can't remember exactly what it's called but not expensive, very strong bond and about 1.5 - 2mm thick, various widths. Mine has green removable backing foil. I bought a couple of rolls a while ago and use it for all sorts of jobs
As an aside, the dashcam subject is of great interest. My wife had a very recent altercation with a motorcyclist who came out of a side road without looking, damaged her car, his bike and several bones in his foot.
No blame, she was on the major road and he didn't stop at the T junction but luckily an advanced motorcycle instructor witnessed the incident and submitted a statement - a camera would have been invaluable otherwise.
Rider is ok btw apart from broken foot and had it not been that my missus was able to swerve as well as brake the guy might be deceased!
So dash cams are planned for both cars and probably motorhome as well!
