Akuvox - R20K - Multi-Subscriber Call Molding Silver Panel
The Akuvox R20K is one of the most compact and affordable multi-subscriber call panels on the market. Thanks to its modest dimensions, it can be installed where most competitors simply cannot. The same can be said of its price: a solution based on the R20K can accommodate even the most modest of budgets. At the same time, it is a fully featured SIP device that can solve the problem of providing access to apartment buildings or office centres.
Product Overview
Vandal-resistant IP intercom with numeric keypad, RF card reader, and two-way VoIP communication. The unit supports PoE (IEEE802.3af), SIP protocol for PBX integration, and ONVIF compliance for surveillance system compatibility.
Key Configuration
- • 110° horizontal / 58° vertical camera viewing angle
- • 2 relays (12V, 2A max load per relay) for door control and signaling peripherals
- • RFID reader: Mifare, Em-Marine, NFC (13.56 MHz and 125 kHz)
- • 1 x RJ45 10/100M Ethernet port, 1 x Wiegand port
Key Features
- • PoE IEEE802.3af — single cable for power and network
- • Two-way VoIP communication with echo cancellation
- • SIP standard compatible for direct connection to SIP PBXs
- • ONVIF compliant for surveillance system integration
- • IP65 moisture/dust protection, IK06 impact resistance
- • Protocol support: IPv4, HTTP, HTTPS, FTP, SNMP, DNS, NTP, RTSP, RTP, TCP, UDP, ICMP, DHCP, ARP
Technical Context
The unit combines access control (keypad + RFID card reader) with video intercom functions. SIP compliance enables direct registration to IP PBX systems without proprietary gateways. ONVIF compliance allows the video stream to be recorded by third-party VMS or NVRs. The two relays operate independently for door strike, maglock, or auxiliary device control.
Installation Notes
IP65 rated for outdoor exposure; IK06 vandal-resistant housing. PoE eliminates the need for a local power supply. Operating requires Cat5e/Cat6 cabling to the PoE switch. Wiegand port available for external card readers if needed.
