I am shopping for a decent HD camera system for my kawasaki vulcan 650. I've installed a cheap 720p system with recorder (screen) under the seat. It isn't HD and I can't read license plate numbers farther than 2 meters away. Removing two seats to access the SD card is a pain. I don't understand why make a DVR with screen it hide from view. That said, it was cheap and works as advertised. The Innovv K1 isn't much better, especially considering the price. The cameras are big and wiring is running everywhere! The recorder overheats. 1080p isn't useful when you can't see the traffic clearly. Being able to read a license plate is essential. Waterproofing is essential. Why aren't the GPS and DVR at least slashproof? I think I'll wait for Innovv to catch up with technology.
