Had been looking for a black box to install on my BMW K1300S for a while, and Kendall, one of friends show me INNOVV K1 2 Channel motorcycle recording system installed on his bike. I should say that was what in my mind, and purchased one set from INNOVV website and got it within a week. The first class delivery service as Kendall mentioned.
I really like its features, that no body can see the cameras installed in front and rear, and you do not worry about battery and SD card get fulfilled.
The front camera.
The rear camera
