How to install Grandstream IP Audio Door System GDS3705

• Plan the installation by identifying entry points, ensuring network readiness, and confirming PoE availability or DC power provisioning according to site requirements.
• Mount the GDS3705 at the designated entry point, aligning the device for optimal audio pickup and visitor visibility (without video), and connect the door strike relay to the building’s door mechanism following local electrical codes.
• Connect the device to the network via PoE capable switch or provide DC power as needed; verify Ethernet connectivity and verify that a valid IP address is assigned (static or DHCP) for management access.
• Access the web-based management interface to configure SIP server settings, register the device with your IP-PBX or SIP platform, and set up basic door control rules (door release on authenticated call, timer settings, and event notifications).
• Test visitor calls, two-way audio clarity, and door release functionality; fine-tune audio levels, privacy options, and notification methods to fit your environment and user needs.
• Review security and maintenance routines—update firmware as required, monitor logs for access events, and perform periodic health checks to ensure ongoing reliability and performance.
