Review on PA2 Video Intercom Paging Gateway by Ryan Eppinger

This device has everything you could want: PoE SIP TA driving speakers directly through a built-in amplifier of up to 30W, line-level audio if You want to control a more powerful standalone amplifier, relay contacts for remote control of lights or doors, and the ability to integrate this camera into an existing Ethernet point via an RJ-45 pass-through connector. And all this in the smallest form factor of all power amplifiers. Lots of sound and auto reply mechanics so you can get it working in almost any PA app. Brilliant.
