Control4 SIP Audio  Video Door Entry Phone Intercom

Products : VoIP Door Phones

We have successfully integrated our ALPHATECH-FERMAX range of SIP audio and video intercom door stations into the Control4 Home Automation system. This audio and video SIP integration allows the ALPHATECH-FERMAX intercom door station to talk directly to a Control4 system on any intercom enabled Control4 touchscreen. The touchscreen can trigger door or gate locks/strikes that are connected to the ALPHATECH-FERMAX door station whilst on a call or from the security/locks section of the interface. Users can also view the camera whilst not on a call to monitor the outside of their home. The driver is licensed, the license key is issued based on your Control 4 unique MAC Address. The license key is invoiced with the purchase of the door station. Please read the setup guide below for more details. 

For Fermax partners we offer SIP VoIP audio-video PCB board, the "SIP ALPHATECH-FERMAXv2", suitable for integration into Fermax Cityline, Fermax Skyline and Fermax Marine panels.
