Can burglar alarms be triggered just by jiggling a door?
If someone shook a front door, could the burglar alarm go off? This is kind of urgent.
also: could the alarm company tell whether the door was entirely opened or if it was simply jiggled?

I wouldn’t have thought so but I’m no expert. Perhaps if it was shaken with some force maybe.

Depends on the kind of door and contact.
If it is a sliding door it can happen….
For a regular door it will happen if the contact is not at the right place or it is mechanical plunger /wheel type with a lot of play.
Some doors also may have a glass break sensor which may go off when the door is shaken hard.
No.. the alarm co. will not know if the door was opened or jiggled, as the switch gets tripped, they have no idea for how long the door was opened, and to what degree it opened.

normally no, but if the door is loose and can move a lot it might trigger alarm

Is it your alarm? If you want to know so you can break into places, good luck. Here is what I will tell you (married to an alarm man 7 yrs) all alarms are different. some have glass break some have motion detectors, some have opening and closing,some…….the home owner can decide what they want and what they want to pay for it.
And to answer you YES that can set off some alarms. But not most. If you open the door even a little it WILL go off.
