The company wants to improve its security to detect and alert them in case of such an event in the future. Which of the following options would be the most effective solution to immediately alert the authorities and company personnel when an intruder gains access to the facility?
Installing a monitored alarm system that sends an alert to an external monitoring service and company personnel when triggered
Setting up a silent alarm that subtly signals only the company personnel without informing the intruder
Using a standalone siren that activates upon sensing motion during non-operational hours
Placing multiple closed-circuit televisions (CCTVs) at all entrances
