Whether we’re looking at the networking of computers, or high resolution IP based security cameras, the underlying basics are common to both.

These devices (and they may include IP printers, routers, gateways, wireless access points and other hardware in addition to computers) are all normally interconnected with Cat5e or Cat6 network cabling, which links the device to a network switch. The devices each have unique IP (Internet Protocol) addresses so that they know what other device they are communicating with.

In some situations Wi-Fi (wireless) is used instead of, or to complement wired / cabled networks, but don’t be fooled into thinking wireless is as good as wired: it is not. Wireless – as a general rule – is slower, more difficult to configure, and more likely to give rise to networking problems.
