Analogue systems can be cheaper than IP systems – High definition analogue systems (often named HDCVI or HD Analogue) are comparable in quality to high definition IP systems, but are usually marginally cheaper if installed in smaller applications.
Analogue Systems can use existing Coax cable – HD analogue cameras can be cabled using your existing coax cable without the need for converters.
Analogue systems are restricted in size – HD analogue systems are more commonly used in smaller applications such as residential or retail and require each cable to be wired back directly to the recorder.
IP systems can use the existing network infrastructure – Unlike analogue cameras, IP cameras don’t have to be wired back directly to the recording device, they can be wired to the nearest network hub or switch and the existing network infrastructure can be used to carry video signals to the NVR, eliminating the need for un-necessary wiring.
IP systems have superior wireless capabilities – IP cameras have the flexibility to integrate with a wireless network and are virtually unlimited in terms of expansion. Analogue wireless cameras use radio frequencies and are limited to about sixteen cameras before they reach full capacity
IP Systems can accommodate a wider variety of camera technology – There is a wider variety of IP cameras i.e. PTZ cameras, 360-degree (fisheye) cameras, Panoramic cameras etc, which are not currently available in HD analogue.
