Mine is a cheap Chinese eBay special. I've just fitted this one
https://www.ebay.co.uk/itm/386795795327 to my new bike.
If you look carefully you can just see the front cameras on both bikes, tucked under the "chins" on the off-side of the fairings.
You can see the rear camera on the old bike in this picture. It's mounted just above the rear light.
The main recorder unit lives under the seat (The H2 SXs have space under the seat - a concept alien to K1?00S owners!
) and is wired in to a switched circuit to activate. You can see the button for the save file option in this picture
It's the red one below the Scotoiler controls on the left bar.
