Grandstream GSC3560 Smart Outdoor Audio Intercom

The Grandstream GSC3560 is a hard-wearing outdoor door intercom for sites that need a reliable audio entry point rather than a full video system. It sits on your network over a single PoE+ cable, registers as a SIP endpoint, and rings whichever handsets, control stations or mobile apps you choose to route it to.

The housing is built for the weather and for abuse: IP66 sealing against driving rain and dust, and IK10 impact resistance across the metal face and buttons. Inside, a dual-microphone array picks up speech from as far as six metres and a 10-watt speaker cuts through traffic and wind, while AI-based noise suppression strips out background racket so the person on the other end can actually be understood. Two relay outputs — including an anti-magnetic solid state relay — handle lock release and alarm linkage without a separate controller.

Ideal for

• Gated yards, car parks and delivery entrances
• Industrial units and warehouses with exposed door positions
• Schools, colleges and public buildings needing vandal-resistant entry
• Residential blocks and small developments where video is not required
• Sites replacing analogue door entry with SIP
• Locations where magnetic tampering of the lock relay is a concern

Key features

• IP66 and IK10 rated — sealed against rain and dust, and impact-resistant across the metal surface and buttons
• 10-watt speaker — 90 dB in intercom mode and 100 dB for broadcast, loud enough for noisy outdoor sites
• Dual-microphone array — picks up speech from up to 6 metres away from the panel
• AI noise suppression — filters traffic, wind and machinery so callers are understood first time
• Two relay outputs — lock control and alarm linkage, including an anti-magnetic solid state relay that resists magnet attacks
• Single-cable install — one 10/100 Mbps port with IEEE 802.3at Class 4 PoE+, or local 12–48V DC power
• Multiple unlock methods — open the door from a SIP call, the Grandstream SecureAccess app, or your own system via HTTP API
• Wide operating range — rated from -40°C to 70°C, so it copes with UK winters and unshaded south-facing walls
• Encrypted by default — 256-bit AES, TLS and SRTP protect audio and configuration
• Cloud managed — GDMS and TR-069 provisioning for remote setup and firmware updates
