The ProSafe FS108P provides power and data from a single point, using Power over Ethernet (PoE) over a single Cat-5 cable. In addition, it discontinues the power when PoE devices are disconnected. These devices are optimally installed on a ceiling or high on a wall, away from most electrical outlets.
Very good, as all Netgear products are. I know (through experience) that for critical reliability, this is the best quality, and I thoroughly recommend this for long term install-and-forget installations. The components and engineering design within all Netgear products like this are absolute top grade.
