    @ chad: i dont think this is a camera system. probably just a infared diode, sensor, and a buzzer.

    PCB = Printed Circuit Board

    how do you plan on making that 1×1 and how tall. 9v batteries are larger than 1inch. the send box may be 1×1 but not the send and receive boxes together. also probably not world’s smallest, definitely not most secure.

    I have actually made an alarm thats 1×1. It uses all radioshack parts too. It triggers when an infrared beam is broken. I never thought about selling them though. I might consider it now though.
