The correct answer is D) 2 and 3 only. The basic functions of a CCTV system are to allow remote observation of a scene and to record activities for later review.

– Statement 1 is incorrect because a CCTV system is a surveillance tool; it monitors and records but does not physically prevent unauthorized entry. Access control systems (like locks, turnstiles, card readers) perform the function of disallowing entry.
– Statement 2 is correct. The primary purpose of CCTV is to transmit video from cameras at one location to monitors at another, allowing personnel to observe a scene remotely.
– Statement 3 is correct. Recording video footage is a standard and essential function of modern CCTV systems, allowing for investigation of incidents, monitoring trends, and evidence collection.

CCTV (Closed-Circuit Television) systems are widely used for security, surveillance, and monitoring in various environments like public places, buildings, traffic management, etc. While CCTV is often part of a larger security system that might include access control or alarms, its fundamental functions are remote viewing and recording.
