Description
When staff need to speak with visitors at a school entrance during a rainstorm, verify a delivery driver at a loading dock in high winds, or quickly release a door at an industrial gate, garbled audio or unreliable hardware creates costly delays and frustration. The Grandstream GSC3560 Smart Outdoor Intercom solves these problems with advanced AI-powered noise suppression that keeps conversations intelligible, a high-output 10W speaker that cuts through ambient noise, and a rugged metal housing built for real-world outdoor punishment.
The Telecom Spot Take
Facilities managers and IT directors at K-12 schools, manufacturing plants, warehouses, and multi-tenant residential communities choose the GSC3560 because it delivers dependable voice intercom performance and access control integration without unnecessary video hardware. The dual-microphone array reaches visitors up to 6 meters away, reducing the need for people to crowd the unit. One relay output uses a solid-state design that resists magnetic tampering common in higher-security installs, while the second handles standard door strikes. With a -40 °C to 70 °C operating range and IP66/IK10 ratings, the unit performs reliably after one-time installation in exposed locations. For teams already using SIP-based phone systems or Grandstream platforms, this model adds outdoor reach and control I/O with minimal complexity and strong long-term value.
Key Features
- AI-Powered Noise Suppression (exclusive to GSC3560): Background noise from traffic, HVAC systems, playgrounds, or machinery gets filtered in real time so voices remain clear and intelligible. This reduces repeat calls, missed instructions, and the time staff spend clarifying messages.
- Dual-Microphone Array with 6 m Pickup: Visitors can speak naturally from a comfortable distance instead of leaning in or shouting. This improves accessibility for delivery personnel, parents, employees with mobility considerations, and anyone approaching in poor weather or low light.
- 10W High-Power Speaker (90 dB Intercom / 100 dB Broadcast): Announcements and responses cut through ambient noise at busy docks, construction perimeters, or large outdoor areas. Broadcast mode supports effective paging without additional external speakers in many scenarios.
- IP66 Weatherproof & IK10 Impact-Rated Metal Housing: Dust, driving rain, snow, and attempted vandalism won’t stop operation. The durable construction protects your investment and keeps critical entry points functional year-round with minimal maintenance.
- Versatile I/O with Anti-Magnetic Solid State Relay (SSR): Two relay outputs let you control everyday door strikes plus high-security locks resistant to magnetic interference. Two alarm inputs accept signals from sensors (smoke, intrusion, temperature), while the differential line output supports external speakers or induction loops for inclusive announcements.
- Flexible Power & Installation Options: Power via PoE+ (IEEE 802.3at Class 4) for simple single-cable runs or optional 12–48 V DC. Wall, pole (optional kit), or flush mounting (optional kit) fits nearly any site layout without custom fabrication.
- SIP Paging, Multicast & Priority Call Handling: Integrates directly with existing VoIP phone systems for group announcements or prioritized emergency calls. Call-waiting with priority override ensures urgent messages aren’t missed during busy periods.
- Cloud & App Management Ready: Works with Grandstream GDMS platforms and the SecureAccess app for remote unlock commands, alarm notifications, and live status checks. Home Assistant compatibility opens the door to custom smart-building automations.

Frequently Asked Questions
Does the GSC3560 include a built-in camera or video calling?
No. The GSC3560 is an audio-focused smart outdoor intercom optimized for clear voice communication and access control. It does not have a camera or video capabilities. If you need integrated video, the GSC3565 model adds a 4 MP camera with AI motion detection.
What types of door locks or strikes can this unit control?
It provides two relay outputs. Output 1 is a standard auxiliary relay suitable for most electric strikes and maglocks. Output 2 uses a solid-state relay (SSR) specifically designed to resist external magnetic interference, making it well-suited for higher-security lock control where tampering is a concern.
How far away can visitors speak and still be heard clearly?
The dual-microphone array maintains clear pickup from up to 6 meters (about 20 feet). Combined with AI noise suppression, this allows natural conversation even when visitors approach from a short distance or in noisy outdoor environments.
What power options are available and is PoE supported?
Yes. The unit supports IEEE 802.3at PoE+ (Class 4) for convenient single-cable installation, or you can power it with an optional 12–48 V DC supply (2 A, 24 W max). This flexibility helps on long cable runs or sites without PoE switches.
Can it work with my existing SIP phone system or paging setup?
Absolutely. The GSC3560 supports standard SIP paging, multicast paging, and call-waiting with priority override, so it integrates directly with most VoIP phone systems and Grandstream UCM platforms for unified calling and group announcements.
How durable is it for outdoor use in extreme climates?
The entire unit carries IP66 weatherproofing and IK10 impact resistance. It operates reliably from -40 °C to 70 °C (-40 °F to 158 °F) with 10–90% non-condensing humidity, making it suitable for exposed locations in harsh winters, desert heat, coastal salt air, or industrial environments.
