Network points are wall-mounted ports into which you can connect an ethernet network cable from your computer or other device in order to physically connect to a network of other devices, including routers, switches, Pcs, laptops and smart devices such as TVs. Each network point can be used by a single device but some network points can have a dual or quad output, which allows for more devices to connect.
Network points can be either flush-mounted or surface-mounted.
Flush-mounted network point
flush-mounted network points, as the name suggests, are network points that are installed flush with the wall that they are installed on. Similar to power outlets, they make use of hidden conduits behind the wall to house their cables. These types of installations are popular when building a house or office, as they require sunken conduits or require the wall to be chased beforehand. Chasing is a very messy job that few people would want done in a completed premises.
Surface-mount network points are very neat and attractive and usually very inconspicuous.
Surface-mounted network point
Surface-mounted network points use what is commonly called a wall-box that is mounted on the wall and extrudes from the wall. They are easy to install in established houses and offices and are not difficult or messy to install. These are the most common type of network points as they can easily to added to an existing network. The network cables are hidden in surface-mounted trunking, which can be painted and blend in well with the wall they are attached to
