Also, I hope it doesn't get triggered by the neighbor's loud tv set.

Frankly, I'm not sure if I'd be prepared to receive and deal with false positives even once a month, let alone once a day.

Agreed, a system with false positives is worse than no system at all imho because it trains you to disregard warning signs.

My apartment was broken into because the security system was disabled. The security system was disabled because it used a cheap glass break sensor that would trip if both my dogs barked at the same time - both, not just one. Naturally this was untenable.

I'm a bit leery about glass break sensors, to say the least.

We're combining data from different sensors, so if Point hears broken glass, and then notices the temperature changing or street noise being louder than usual we can more accurately detect broken windows.

OK, this is actually a really cool approach to what I gather is a common problem!

Does Point try to learn a baseline for temperature/acoustics/etc., and trigger when a deviation occurs? Or do you just say "when glass breaks + these other thresholds are tripped, ..."

Because the latter would probably solve the problem fairly well, but the former would be outstanding.
