Analogue cameras have been around for decades, and they continue to offer good service in particular security settings. With classic CCTV technology, transmission occurs through coaxial cables. A video recorder provides the footage. Analogue CCTV systems are ideal for small applications where the DVR and cameras are not more than 300m apart. As technology advanced, so did analogue CCTV. Now you can get systems with up to 8MP in resolution. Power over Coax (PoC) technology has also revolutionised analogue surveillance cameras. The technology allows both the power and CCTV signal to transmit over the coaxial cable, thereby reducing the number of components necessary during installation.
