Analogue CCTV 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. CCTV cameras 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. Though the infrared is fixed, you can choose 20, 30, or 100m. Colour and
Starlight cameras are also available to let you see colours and images,
even in the dark.
