Do You Need an Intruder Alarm If You Have a Guard?
DiTi Service engineers · updated 26.09.2026
Short answer
A guard cannot watch every door, window and room at once, especially at night, so the best approach is for the alarm to detect and the guard to respond.
A guard cannot see every door, window and room at the same time, especially at night. An alarm system watches everything at once and shows exactly where the intrusion happened.
The best option is both: the alarm detects, the guard responds.
Practical tips
Send alarms to the guard's phone or desk so they can respond immediately.
Add a panic button for guards and staff.
Combine the alarm with CCTV so the guard can see the cause.
Frequently asked questions
What should a guard do when the alarm goes off?
Follow the instructions: check the zone on cameras and call a response team or the police.
Can arming follow a schedule?
Yes, many panels support scheduled arming and disarming.
