A small business recently suffered an overnight break-in. Management wants a solution that will automatically detect an intruder and immediately alert both on-call staff and law-enforcement so that help can be dispatched without delay. Which of the following would BEST meet this requirement?
Mount a standalone motion-activated siren that sounds inside the building after hours.
Install a professionally monitored alarm system that automatically notifies a 24/7 monitoring center, which then contacts keyholders and police when sensors are triggered.
Provide employees with a silent panic-button alarm that discreetly informs on-site staff when pressed.
Deploy closed-circuit television (CCTV) cameras at every entrance.
A professionally monitored alarm system ties door/motion sensors to a 24 × 7 alarm-receiving center. When a sensor is tripped, operators verify the event within seconds and then notify the designated keyholders and dispatch police, providing the quickest, automated response .
CCTV cameras mainly supply video evidence; unless someone watches them live, they do not generate real-time police alerts .
A silent panic-button alarm can discreetly contact staff or police, but it must be pressed by someone on-site and therefore will not by itself detect an after-hours intrusion .
A standalone siren only produces a loud local sound; it has no means to contact responders .
