Grandstream GSC3575 Android Intercom Station with Handset

The Grandstream GSC3575 is an Android-based IP intercom control station that pairs a 7-inch capacitive touchscreen with a dedicated HD handset — a combination the specification marks as specific to this model within the GSC35 series. An operator can view a live 720p video feed from a connected door station, take the call hands-free through the full-duplex dual speakers with echo cancellation, or pick up the handset for a quieter, private conversation. Six alarm short-in inputs and two relay outputs let the same console trigger a door strike, a gate, or a site alarm directly from the desk, and Android 13 with 2GB of RAM and 8GB of onboard storage run the on-screen interface without a separate PC.

Handling Calls and Access at One Desk

Six SIP accounts let the GSC3575 register to the same PBX as other intercom endpoints and take calls from multiple door stations or extensions without a phone system upgrade. The dual speakers and echo-cancelled full-duplex audio keep hands-free conversations clear even when the operator is speaking while the caller is still talking, and the handset gives a fallback for calls that need a quieter, private line rather than a desk speaker. A single USB-A port and a microSD slot support local accessories and storage expansion, while the 1024×600 display shows the live video feed, caller information and alarm status together on one screen instead of requiring separate hardware for video and access control.

Physically, the GSC3575 measures 182 x 122 x 26.2mm, a slim profile suited to flush wall mounting or angled desktop placement using the bundled 0-degree and 20-degree brackets. The video input runs at up to 1280×720 resolution (720p) at 30fps, enough to identify a visitor’s face or read a delivery label on the connected door station’s camera feed without a separate monitor. A Bluetooth 5.0 radio pairs with wireless headsets or beacons at the guard desk, running alongside the WiFi 6 connection rather than replacing it. Because the console draws power over the same 802.3af Class 3 PoE link used for data, a site with structured cabling to the guard post needs no additional electrical work to bring the unit online.

Where the Grandstream GSC3575 Fits in a Saudi Deployment

The combination of video intercom, handset and alarm I/O suits guard rooms and reception desks in Saudi facilities that need one console for both visitor calls and basic access control — gated compounds, warehouse security offices, and building lobbies where a single guard answers door stations, releases a gate via the relay outputs, and logs who requested entry. The PoE-powered network port means the console runs off the same cable as the data connection, useful in guard huts and security cabins where pulling a separate power circuit is inconvenient, and the integrated WiFi 6 and Bluetooth give a wireless fallback for temporary posts or mobile guard stations set up during events.

Positioning Within the GSC35 Series

The HD handset on the GSC3575 is specific to this model in the GSC35 series, giving it a physical fallback for calls that a touchscreen-only console cannot offer — useful when a guard needs a private conversation rather than a hands-free call broadcast across a desk. Combined with six alarm inputs and two relay outputs on the same unit, the GSC3575 functions less like a simple video intercom endpoint and more like a small access-control console: it can view the door camera, talk to a visitor, and release a door or gate without switching to separate hardware. That combination — handset, video, and alarm I/O together — is what sets its role in the family apart from members built purely as call-handling touchscreens.

Deployment Notes

The GSC3575 connects over a single 10/100Mbps Ethernet port with 802.3af Class 3 PoE, so power and data arrive together over one cable to the desk or console point. The unit weighs 408g on its own and ships at 729g, light enough for wall or desktop mounting without special bracket reinforcement. WiFi 6 (802.11ax) across both 2.4GHz and 5GHz bands and Bluetooth 5.0 back up the wired connection where a guard post needs to move or a network drop is not available at final placement.
