Hi,

I need a intercom system for apartments building to control visitor
access into the garage.

The scheme: visitor key-in apartment number to buzz the occupant,
occupant answers and can have 2 way conversation, then can decide to
open the garage door. -- usual stuff --

o Wireless / Cordless, no laying cable around the building
o Operating in license-free frequency
o For access to at least 30 apartments
o Range up to 100 meter in 2 storeys building, repeater/extender can
be installed if needed
o Digital technology
o Ready in the market for immediate purchase, not in development stage
o No maintenance cost except the electricity
o Purchaseable / Importable to Australia, no export restriction whatsoever

Note: Don't worry about the gate opener itself. Just need the intercom system first

In this wireless world , is there such a product ?

What I need for the answer:
o Brand and model and price of the system
o Name / Contact Number / Website of the seller with specification

Thank you very much !
