The CyberData SIP Outdoor Intercom with RFID is perfect for secure access settings requiring RFID access control and two-way communication. With encrypted RFID, the SIP Outdoor Intercom can increase the security of any VoIP installation. The product supports up to 500 RFID cards. A card with a blacklisted code will trigger a phone call with a pre-recorded message and/or a multicast stream to IP notification endpoints. The access code list, designating valid entry times or blacklisted users, can be updated manually using the web interface, imported using the web page, or autoprovisioned using the same mechanism as a VoIP phone. CyberData has maintained one of the most comprehensive lists of IP PBX servers certified to work with CyberData VoIP Products.
