Quote from: "Alex S"So it makes sure guards do their rounds...You'd be right, a 1.5v AA battery probably couldn't handle data writing. Lithium coin cell batteries last a while, and provide more voltage than alkaline AA-type batteries. I would guess that those are the types of batteries used.You mentioned that it stores data for future review? The batteries could be changed when the data is analyzed.Are you planning to just create a 'functional' replica (i.e. something that just copies the functionality of another device)?
Quote from: "Sora"Hold the phone. Are you trying to reverse-engineer the signal so that you can tell it you've pushed the button when you haven't? So that you can fudge off work? Anyway, you'd need a frequency detector of some kind, and those are expensive...
