Fanvil i503W Wireless SIP Indoor Station
The Fanvil i503W is a compact, wire-free SIP indoor station designed for apartments, villas, offices and retrofit projects where installing new network cabling may be difficult. Its rechargeable battery, dual-band Wi-Fi 6 connectivity and USB Type-C interface support flexible desktop placement, while the colour display and dedicated physical controls provide convenient access to everyday intercom functions.
Flexible Wireless Intercom Communication
Designed to communicate with compatible Fanvil door phones, the i503W supports audio and video calls, remote door unlocking and one-touch family calling. Its wireless design can help reduce installation time and cabling requirements in existing buildings.
Key Features:
- 2.8-inch IPS colour display with a 320 × 240-pixel resolution.
- Supports audio and video communication with compatible Fanvil door phones.
- Dual-band 2.4 GHz and 5 GHz Wi-Fi 6 provides flexible wireless network connectivity.
- Built-in rechargeable battery and USB Type-C interface support convenient indoor placement and charging.
- Five programmable physical buttons provide quick access to calling, door unlocking and other configured functions.
- G.722 and Opus wideband audio codecs, full-duplex hands-free communication and acoustic echo cancellation support clear conversations.
- Up to 5-metre voice pickup helps users communicate from around the room.

Practical Controls for Everyday Access
Dedicated physical controls can be used to answer or end calls, unlock a connected door, enable Do Not Disturb and call other indoor stations. The buttons may also be configured through the device’s web interface for functions such as speed dial and door unlocking.

Designed for Retrofit Installations
Battery-powered operation and wireless networking make the i503W particularly useful for legacy buildings and other hard-to-wire environments. Automatic discovery can also help the station find compatible kit devices connected to the same network.

Clear Audio and Video Communication
The station supports the SIP 2.0 protocol, H.264 video and a selection of narrowband and wideband audio codecs. Full-duplex hands-free communication with acoustic echo cancellation helps make indoor conversations more natural.
