Grandstream GSC3565 Smart Outdoor Video Intercom (GSC3565)

The Grandstream GSC3565 Smart Outdoor Video Intercom is a rugged, IP66 and IK10-rated SIP-based video intercom designed for demanding outdoor deployments including schools, residential communities, SMBs, metro stations, senior living facilities, and high-security environments. The entire unit — including the lens area — carries the IP66 and IK10 rating, providing industrial-grade protection against dust, water, and impact across every surface.

The GSC3565 features a 1/3" 4 MP CMOS image sensor with HDR support, delivering up to 1920 × 1080 resolution at 30 fps with a 127° horizontal field of view and wide dynamic range up to 120 dB. Six auto-brightness white LEDs provide smart light supplementation, while AI-based motion detection enables intelligent video analytics. Door unlock is supported via SIP call, HTTP API, QR code, or the Grandstream SecureAccess app.

Audio performance is delivered by a dual-microphone array with a pickup distance of up to 6 m and a high-performance 10 W speaker. A built-in Solid State Relay (SSR) on the second relay output provides robust protection against external magnetic interference for high-security lock control. Connectivity is handled via a single 10/100 Mbps PoE+ (802.3at) Ethernet port. Cloud-based management is available through GDMS UC, GDMS SecureAccess, and the Grandstream SecureAccess app, and the GSC3565 is compatible with Home Assistant for smart integration.
