Analogue CCTV systems have become a thing of the past and have been replaced with HD (high definition) systems. IP CCTV systems are the latest in technology providing a complete digital solution resulting in better image quality with advanced recording options. Although the standard view of the CCTV footage between HD and IP systems are similar at a glance, the major difference is noticed when zooming in to identify e.g. number plates, peoples faces etc where IP is far superior. IP Systems also require less cabling with no cable clutter at the location of the NVR (Network Video Recorder) and also capable of long distance wireless transmission.

In a nutshell, IP CCTV systems are the best all round and are recommended for new installations. It allows for a neater installation with no cable clutter at the NVR, less cabling is used overall, has much better resolution, greater image display requiring less cameras to monitor the same area as analogue / HD, less pixelation when zooming, more technological advancements and much more. 

Analogue and HD systems use coaxial cable for video and separate cabling for power to the cameras. So if upgrading from an old analogue system, the same cabling can be used for HD systems. Each HD camera must be wired directly back to the DVR resulting in cable clutter at the location of the DVR, the more cameras installed, the more cable clutter. 

IP Systems use CAT5/6 network cable for video and the same cable provides power to the cameras via PoE (power over Ethernet) switches. Cabling from the IP cameras are connected to one or more PoE network switches conveniently located in close proximity to the cameras with only one cable returning to the NVR. 

If you are considering upgrading from your existing Analogue system and you’re on a budget, HD cameras are the way to go as its just a matter of swapping cameras and the DVR, your existing cabling and camera power supplies can be used. Some HD DVR’s today can also accommodate IP cameras so you can connect your existing analogue / HD cameras as well as adding a few IP cameras to the same system.
