Meet the LookOut phone adapter: a smartphone charger with a security camera built-in to allow you to record 1080p video discreetly. It doesn’t have a SD card slot, pinholes, and other obvious signs to raise any suspicion. Just plug in the device to start recording. The camera records to 32 GB internal memory.
You will be able to access all the footage on your Mac, PC, or Linux machine. LookOut can serve as a charger for your iOS or Android device. Expected to ship in August.[Source]
