hey was looking at vibrations and have decided to ask questions.
I get that speakers work of vibrating making the noise, and microphones work by recieving vibrations.
I also understand basics of seismographs and the basic principals of of detecting vibrations for alarm systems.

the question i have is I see there are alarms that pick the specific frequency to detect glass breaking from the sound it makes. how hard would it be to make an alarm that detects the difference between a wire fence blowing in the breeze or being shaken(or is it shook?) by a tremor as opposed to being clmbed over? would there be any other vibrations i would have to factor in? I assume cats or possums climbing a fence would be one

Seems like a lot of possible variables to set off the alarm.
Did you consider optical? Beam of light being broken? Maybe one of the game-trail
camera-type devices that are triggered by activity. Proximity sensors or even pressure
tape on your side of the fence. A watchdog?
