As an integrator we often get humorous requests such as the one above. Even though the client is joking what they are really looking for is ACTIVE security while an intruder is on site.
We recently designed an IP camera system where the User can manually trigger several outdoor siren/strobes by the VMS. When the User receives an email alert that there is movement in front of the cameras they can use their discretion if the siren/strobes need to be activated. The User then activates via the VMS.
The Client feels like they are doing their part to fight crime and the intruder leaves and losses are reduced.
Instead of an alarm simply triggering a siren or a camera triggering an email, what's the best ACTIVE security solution you came up with?
