Which of the following is/are the basic function(s) of a CCTV system ?
1. To disallow unauthorised persons to enter into any building in the premises
2. To allow a person to observe a scene without being present at the scene
3. To allow an activity to be recorded for future viewing
Select the correct answer using the code given below :
Explanation
A Closed-Circuit Television (CCTV) system is primarily a surveillance technology used for monitoring and security. Its core functions are:
- Surveillance: It enables a person to monitor a specific area or scene from a remote location in real-time (Statement 2).
- Evidence and Review: It allows for the recording of activities, which can be stored and viewed later for security audits or legal evidence (Statement 3).
Statement 1 is incorrect because CCTV is a passive surveillance tool. While it may act as a deterrent, it does not physically or electronically "disallow" or block entry. The function of preventing unauthorized access is performed by Access Control Systems (such as biometric locks, RFID readers, or physical barriers like gates and guards).
