Figure out if the camera needs movement whether vertical, horizontal or both. Calculate the optimum distance. All these small details are needed when installing CCTV cameras.
IP based systems have 32 bit numbers that is unique and perfectly works with CCTV cameras in networked systems. The cameras will be networked so that it can be view globally. This can be done due to the unique IP addresses being provided.
The CCTV cameras are digital and this is the reason they offer a very high quality of the image and all the information is digitally stored on the hard disk. Thus, there will be no danger of degradation of the quality of the image, like it might happen with the analog equipment.
