Fanvil i503W – Wire-Free SIP Indoor Station

The Fanvil i503W SIP Indoor Station redefines intercom flexibility. Designed specifically for retrofit and hard-to-wire installations, it eliminates the need for power cabling entirely — simply charge via USB-C and connect over Wi-Fi 6.

Featuring a 2.8-inch IPS colour display, the i503W supports both audio and video calls with compatible Fanvil door phones. HD audio is delivered via G.722 and Opus codecs, with a 5-metre voice pickup range and a 5W speaker for crystal-clear hands-free communication throughout the room.

Five programmable physical buttons provide one-touch access to key functions: menu, mute/intercom, keypad, and call. Remote door unlocking and one-touch family calling make day-to-day use effortless.

Ideal for residential communities, apartment buildings, villas, and legacy buildings where running new cable is impractical or cost-prohibitive.
