Control4 Intercom System Dec 1st, 2016. Site last updated by PHA.Control4 Intercom, Control4 has one of the best voice and video intercom systems on the market. We here at Portland Home Automation have installed intercom systems as far back as the early 90’s. We started with the old Music & Sound systems, the Nutone and the Russound systems. But those do not even come close to the Control4 intercom systems.The Control4 intercom systems work hand in hand with the Control4 wall touch screens. The older touch screens were only audio but once the new lines of Touch screens came there was no doubt that Control4 would be putting there hat in the ring with all the other big boys that were in the intercom market.When you add in the Control4 house audio system and front door or gate keypads that also have a camera built into them, you now have a great house sound and video intercom system that covers all zones and even the front door and gate video intercom.Control4 Intercom Systems sales and service.Portland Home Automation.503.740.3870.sales@PortlandHomeAutomation.com.
