Building a Network Infrastructure for Robust IP Video Surveillance.
Many network switches are not upgraded to handle surveillance. The network is a crucial element in any surveillance installation because it enables all the other surveillance functions, transmits video streams using a mix of unicast and multicasting for viewing and storage, and often carries power to the cameras themselves via Power over Ethernet (PoE).
NETGEAR switches offer what is needed for a robust network. More specifically, they offer:
• Adequate bandwidth - The network and the switch(es) that control it must be able to move traffic at “line rate” (full speed) to avoid risking delays, poor camera control or even loss of data.
• Resilience - The network switch(es) must have access to an alternate power supply should the main source of power fail.
• Security - The network must be protected from hacking, including physical hacking.
