But in actual fact, cable is a very critical element in any CCTV system. Cable is like the blood veins to our organs. Your body system will collapse even if you have healthy organs but with clogging or damaged blood veins. Hence the quality of the cable is extremely important.
To connect an analog camera to DVR, coaxial cable is required. The most commonly used coaxial cable are RG59 or RG6.
The simplest rule of thumb of choosing a good quality coaxial cable is to get the fattest thickest wire available.
Another good coaxial option is Siamese coaxial; a combination of coaxial and power supply to the camera.
