Welcome to ETO!
Fine in theory, but you may have to overcome a few problems in practice.
1) If the sensors are buried in the wall, how will you get power to them?
2) Depending on your location, will you be able to differentiate intruder-caused vibration from general building vibration due to vehicles, thunder and minor earth tremors?
3) Will the police take kindly to frequent false alarms? Do they give low priority or even respond at all to domestic alarms?
4) If an intruder gains entry, do you really want to be locked in with them?
5) What precautions will you take to prevent the alarm being triggered by radio interference, or deliberately by a would-be intruder or joker?
