IPGuardV2 is a unique and secure solution which enables 1+1 Automatic IP switching with a hardware bypass mechanism. Designed for IP architectures, it can be used to switch between main & backup IP sources based on a set of configurable criteria in order to provide reliable IP transport and error-free streams.

Real Time, Multichannel, SPTS or MPTS Transport Stream Failover Switching Appliance designed to offer two to one failover for UDP streams. Parameter monitored can be loss of sync or missing PIDs. One Frame Time Cut Over. Ideal product for protecting headends of all types.
