i got kids in my house.. sometimes kids like to slam doors very hard, that cause my neighbours alarm to go off... Sometimes, the wind pushes my door and slams the door very hard -> neighbours alarm goes off..

As for my house, I set my shock sensor such that it only detects double shock before it triggers the alarm. Actually, all alarms can do that.. you just have to read the manual on how to program the shock sensor..

The only thing that wireless are the sensors only.

The control panel and powered by electricity. Also, there's the alarm box, that people put on the outside, so that neighbours and hear the
sound. The alarm box is connected by wires.. You have to hide the wires.


As for batteries, i think it depends on what type of battery they want to use..

wired :
pros - maintenance free
cons - need to do wiring throughout the house..
- the wiring can get faulty .. possibly eaten by rat, or deterioriate itself
due to aging, or bad installation..

wireless
pros - no need wiring
- you change the sensor location anytime, anywhere. And maybe you
want to put the sensors on your cupboard or drawer if you like.. and maybe
stick it at your front gate if the sensor can withstand outdoor condition.
cons - need to change battery periodically..
- if the sensor is put on the roof, you need to climb your roof to change the battery.


As for me, if money not a problem, i'd go for wired, or maybe get both, so I can get
the advantages of both world.
