Aiphone GT Series: Multi-Tenant Color Video Entry Security System


The GH System offers several benefits over other traditional telephone-style entry systems. It’s a direct connect system that does not require an outside phone line at the tenant location and will never incur additional phone company charges. This series improves security by requiring individuals to be at the tenant station to answer calls and grant access. In addition, the GH system offers security guard stations, open voice communication, and tenant monitoring of the entry
