Basic Information About CCTV

CCTV, which stands for Closed-Circuit Television, is a video surveillance system that transmits signals over a private network rather than a public broadcast. This means that the footage captured by CCTV cameras is only accessible to authorized viewers, unlike broadcast television that anyone with a TV can tune into.

IP CCTV Camera

IP CCTV, or Internet Protocol Closed-Circuit Television, represents a modern approach to video surveillance utilizing digital technology and network connectivity. Unlike traditional analog CCTV systems, IP cameras capture and transmit video data as digital packets using the internet protocol (IP). This enables several advantages and advancements over its analog counterpart.

Analog CCTV Camera

Analog CCTV, the original video surveillance technology has been around for decades and paved the way for modern security systems. While surpassed by newer IP technology in some aspects, it still holds its own in specific applications due to its simplicity and affordability.

Difference Between Analog and IP CCTV Camera
