For IP surveillance networks, smart PoE switches give an edge

By By Steven Olen, director of product marketing for business solutions, D-Link Systems, Network World |  Security

Unmanaged PoE switches don't have the ability to alert the network administrator after a change or disruption to the network. Smart switches, however, can send alerts to a network management system (typically SNMP-based) when such challenges arise. For example, a Smart PoE switch can send an alert to administrators when:" An Ethernet link goes up or down (e.g. an IP camera establishes or loses a link)" PoE power turns on/off for any port" A short circuit occurs on any port" A "Power Deny" action occurs on any port

In summary, while unmanaged PoE switches are considered a mainstay of IP surveillance networks because they are low-cost, easy-to-use and good for simple connectivity, more and more security professionals are realizing the tremendous benefits of upgrading to Smart PoE switches. The cost increase is minimal and these switches provide network administrators with a simple, easy-to-use interface through which the IP surveillance network can be configured and monitored from anywhere, anytime.

They also offer additional tools that enable administrators to enjoy faster network installation, easier network maintenance and upgrades, and better visibility into network health. It all adds up to time- and cost-savings that are attractive selling features for today's budget-conscious organizations.
