Overview of Fanvil i16S
The Fanvil i16S is a rugged SIP audio intercom built for demanding indoor and outdoor locations. Its die-cast aluminum frame is rated IP65 and IK10, and an anti-tamper alarm alerts the control center if the cover is removed. A built-in 3W speaker with echo cancellation delivers clear HD voice, while two built-in relays with short-circuit inputs and outputs control doors, barriers or alarms. The TF card slot enables offline audio broadcasting, and the line-out port can drive an external active speaker. Working from -30°C to 60°C on PoE or DC power, it is ideal for parking areas, gates, compounds, factories, campuses and emergency help points.
