Data transfer rate standards have increased dramatically enabling today’s Ethernet networks to provide the performance necessary for demanding IP video applications.
Power over Ethernet (PoE) provides the option of powering devices (IP cameras) connected to an IP network using the same cable that’s used for data communication.
While network bandwidth may have been a scarce resource in the past, today bandwitdth is plentiful but there are still a few things to consider when setting up a network for IP video surveillance.
Power over Ethernet (PoE) lets you use the same Ethernet cable for supplying power and for transferring data. The main benefit is the immense cost savings associated with this. Hiring electricians to install separate power lines is unnecessary. In addtion to that, PoE:
Network servers are very powerful these days with vast amounts of available bandwidth. However, there are some considerations when setting up a network of IP video surveillance:
Build your network with more capacity than is needed and you’ll always be safe as more and more applications are being run over networks and requiring higher performance. And remember that network switches are easy to upgrade after a few years but cabling is more difficult to replace – so you want to make sure to do it right the first time around.
