Held securely, attended properly
We hold your keys securely and attend when an alarm activates, so nobody on your team is driving to a dark site at 3am to find out what triggered it.
An officer attends, checks the premises, establishes whether it is a genuine activation or a fault, liaises with police where required, and either resets and secures or stays on site until it is made safe.
You get a written report of every attendance: time called, time on site, what was found and what was done. Over a few months that record usually tells you something useful about why your alarm keeps going off.
