The Fanvil i31S is a versatile IP video door phone designed to manage building access and communication through two SIP lines. Its rugged construction from cast aluminum in a grey finish ensures durability, while the IP65 rating protects the internal components from dust and water. To withstand physical impact in high-traffic areas, the wall-mountable device is built to IK10 anti-collision standards. Managing entry is straightforward, as you can grant access via a call, a numeric code, or an RFID card. The system connects via a 10/100 Mbps Ethernet port and is powered by PoE IEEE 802.3af, which simplifies installation by combining power and data over a single cable. Measuring 22.3 cm wide, 13 cm high, and 7.4 cm deep, it provides a professional look for any entrance, and the included tool kit helps you get it set up quickly.
