Kaiser Baas R30 Car Camera + WiFi & GPS
To say that good things come in small packages would be modest! The R30 films at a crisp 1296P at 30 frames per second,
and also links to your smartphone via WiFi for playback.
This impossibly tiny camera supports up to 64GB micro SD cards and operates in temperatures between -20˚c and 70˚c. The smartphone App gives streaming functionality, as well as playback, and sharing to social media, meaning that you can have all the functionality of a car DVR with a screen while being discreet enough that you can set it up behind your rear view mirror and not have anything obscure your view, or attract attention to your car.
