The migration from analog infrastructure to networked systems continues to gain traction at a rapid pace given all the inherent benefits networked technology provides for video surveillance and security applications. However, there are costs involved, and they can be significant, especially if the move to networked infrastructure requires the removal of existing wiring and the installation of new Ethernet cabling. One of the greatest challenges involves the distribution of power to various edge devices. Here’s where PoE technology has helped to increase the trend towards networked systems.
