The Inspinia INS-SB24 is a compact single-button outdoor VoIP intercom for residential and commercial entrances. A 2MP CMOS camera (720p, H.264) with LED white-light compensation, built-in microphone and speaker (G.711, echo cancellation), and IC/ID card readers provide video entry and credential-based access on one surface-mounted station.

The aluminum-front station supports SIP, ONVIF, and RTSP for integration with IP monitors, mobile clients, and recorders. Two relay outputs, a tamper alarm, IP65 weather protection, and IK06 impact resistance suit exposed door locations. Power is via PoE (802.3af) or DC 12 V / 2 A.
