A500 Hands-Free IP Audio Intercom Station (Golmar)

The Alpha Communications┬« A500 audio unit uses the IP Plus technology from Golmar to provide the most advanced intercom system available, for any size building, with any number of audio intercom stations, video-intercom monitors, door stations, and remote cameras.

The A500 is a full IP solution for the communication in luxury homes, multi-familuy residential buildings, condominiums and commercial office buildings.

Thanks to its technology and Peer2Peer facilities the A500 units do not require any server for the installation.

The communication protocol is UDP/IP which makes it possible to be connected to a LAN together with other IP devices in the same installation. The system never becomes "busy" thanks to the multi-channel feature. In addition, these stations feature full duplex audio communications.

These attractive stations are conveniently surface mounted right on the wall and are only 0.55" deep! Due to its advanced design and TCP/IP protocol, the A500 does not require any servers, power supplies, switchers, boosters, audio distributors, and requires simply a LAN connection and the PoE switch(es).
