Grandstream GDS3702 – HD Audio IP Intercom with Electric Lock Relay, PoE & IP66 Weatherproof Casing

Someone's standing at your front door. You're three floors up. The old intercom's been dead since the last storm and you've been shouting "yes?" down the hallway.

The GDS3702 is a single-button HD audio IP intercom. Press it, your SIP phone rings, you talk. Two-way HD audio with up to 1.5m input and 3m output range — clear enough that you don't have to ask them to repeat.

It drives your electric lock via relay, takes two alarm-in signals (exit button, door sensor), and outputs an alarm signal to your existing security panel. Integrated PoE means one cable powers the unit and carries the network. No separate PSU hunting for a socket.

Metal casing, IP66 rated, vandal resistant. Works with Grandstream IP phones, the Wave mobile app, and GDS Manager for configuration. SIP/VoIP based, so it slots into whatever phone system you already run.
