Spying on US citizens

Coming off that board, I see two large wires (red and black) running to a battery connector and two smaller, black wires running to what looks like a temperature sensor.
Your hand is holding a heatsink for the board's power electronics. The smaller protruding black knobs aligned with the LEDs are most likely push buttons, according to the layout of the device [1].
A temperature sensor in an UPS (what I believe the box is) is very common, as it would require ambient temperature readings for optimal charge and safety concerns. You will also find them in hard drives, TV sets, switching power supplies, etc. You can buy them in bulk on ebay [2], for cheap.
Is that sensor what you believed to be a microphone? Or did I miss something else?

My other account on here is nlake44. This was my fake account I used to post about my company AppScale. Marketing stuff :)
It's from an old Verizon security system? So... of course it has a mic.
