Guys, do you recommend something you used with success? The house has full crestron, we are installing the new touch panels with Rava ( SIP ) for internal communication of the house. I wonder if there is a gate intercom system ( weather proof of course ) to be mounted outside. My idea is to show the intercom camera on the crestron displays ( either via a composite video out of the intercom into a crestron NVS-200 or some kind of intercom that streams a compatible video stream for the touch panels ) and also 2 way audio via sip, rava, or any other kind of crestron friendly audio protocol. is there such thing???
