Integrated Security System includes : 1. Combined Security Equipment with computers and common communication medium 2. Human Resource Data Acquisition and Management 3. Fire and Life safety 4. Information transfer and information accessibility over Local and Wide Area Networks Select the answer using the code given below :

An Integrated Security System (ISS) is a multi-layered framework that combines various security subsystems into a single, cohesive network to enhance situational awareness and response efficiency. The components mentioned are all integral to a modern ISS:

• Statement 1: ISS utilizes computers and common communication protocols to link hardware like CCTV, sensors, and alarms into a unified interface.
• Statement 2: It includes Access Control Systems (ACS) and Visitor Management, which handle human resource data acquisition (biometrics, ID logs) to manage entry and exit.
• Statement 3: Modern integration includes Fire and Life Safety systems (smoke detectors, sprinklers) to ensure coordinated emergency responses (e.g., unlocking doors automatically during a fire).
• Statement 4: Information is transferred over LAN and WAN, allowing for remote monitoring, centralized data storage, and real-time accessibility across different locations.

This holistic approach ensures that individual security elements do not operate in silos, providing a more robust defense mechanism.
