I have the Innovv K3 installed. They have a better shut down procedure than earlier incarnations of the K3, and have very little drain when the ignition is turned off. However, I have had one unexplained flat battery, the cause of which I cannot find. I have left the camera plugged in for weeks in the garage with no drain enough to prevent starting. But I suspect that if you start up the bike and then turn it off before the camera has gone through its initialisation, it may well stay on. However, I have tried to reproduce this and I cannot. I know this behaviour happened with a previous bullet camera, and it sometimes does it with the Zumo. But I cannot pin my flat battery down to the Innovv Camera.
It is nice kit. The sound is a bit ropy though compared to other cameras. Video records lat/long, time, date and speed. Speed is a bit off compared to satnav speed, and all of these can be turned on or off. Tech support is pretty good too.
Finding a location for cameras, GPS, control unit and wiring it all in is a long job. I have it connected tot he battery - but via a plug/socket. It needs to have power to shut down properly and commit the last 10 minutes recording to the memory card. It starts that when you turn off the ignition. It completes the job within a minute or two. SO if I am away from home, I do everything else that I have to do after stopping the bike, and then unplug the connector. That disables recording in case of the bike getting knocked though.
Recorded files are a maximum of 10 minutes. It then creates a new file. Files are named according to date and time and front /rear. Both front and rear files have the same name and start and stop at the same point of the jorney. At the file changeover, there is no gap - in fact there is a second or so of overlap - so that last second or so at the end of one 10 minute file is repeated at the start of the next 10 minute file. Files can be in one of two formats, one of which is mp4.
I have mounted my front camera onto the bottom of the outside of the windscreen. I drilled a hole. It is quite steady there and moves up and down with the screen, but it makes very little difference to the image (surprisingly). (I practiced on an old screen first).
