The Inspinia INS-K4A24 is a surface-mounted 4.3″ keypad outdoor intercom for residential and commercial entrances. It combines a 4.3-inch TFT LCD, mechanical keypad, and 2MP CMOS camera (720p, H.264) so visitors can be identified and granted access via PIN, card, or optional Bluetooth while building staff communicate over the network.

The station is built for exposed outdoor use: aluminum front panel, IP65 weather protection, and IK06 impact resistance. Power is via PoE (802.3af) or DC 12 V / 2 A. Three relay outputs, Wiegand, and RS485 support door locks, gates, and third-party access control. Network protocols include SIP, ONVIF, and RTSP for integration with VoIP monitors, NVRs, and the wider Inspinia automation ecosystem.

Applications and System Integration

• Multi-tenant residential: PIN and card access for lobbies, car parks, and secondary gates with three independent relays.
• Commercial entrances: SIP video calls to reception desks, concierge apps, or IP indoor monitors.
• Surveillance integration: ONVIF and RTSP streams to recorders alongside dedicated intercom workflows.
• Building automation hub: Pair outdoor stations with the Inspinia MNSRV Mini Server for centralized logic, KNX/Modbus/Zigbee bridging, and SkyPlatform management.
• Indoor touch interfaces: Complement entry points with INS4SQ 4″ SQ Room Controller, INS8SQ 8″ SQ Touch Panel, or INS10SQ 10″ Touch Screen for in-unit or common-area control.
• Alternative outdoor station: Where a single call button suffices, specify the INS-SB24 SIP Video Door Station (2 relays, no keypad display).

Choosing Inspinia Outdoor Intercoms

The INS-K4A24 is the full-featured choice when users need an on-wall keypad, 4.3″ display, and three relays at the entrance. Choose the INS-SB24 for a compact single-button SIP door station with dual relays and no mechanical keypad. Both share Inspinia’s Linux platform, IP65/IK06 outdoor rating, IC/ID readers, SIP/ONVIF support, and PoE or 12 V DC power — select by required UI, relay count, and access methods at each door.
