Grandstream GDS3702 — Common Questions

Everything you need to know about the Grandstream GDS3702 before you buy.

What is the Grandstream GDS3702?

The GDS3702 is an IP audio door access system that provides intercom communication and door control at building entrances. Combined with Grandstream IP phones, the Wave mobile app and third-party IP devices, it forms a complete end-to-end access control and intercom solution.

Does the GDS3702 include an RFID reader?

No. The GDS3702 is the simpler audio door station. If you need built-in RFID card entry and a keypad for PIN codes, the GDS3705 provides those features.

What door hardware can the GDS3702 control?

It provides two relays for an electric lock and alarm output, and two alarm inputs for an exit button and door sensor, so it can both release the door and monitor its state.

Is the GDS3702 suitable for outdoor use?

Yes. It is built with a metal casing designed to be weatherproof and vandal resistant, so it can be installed at exposed external doors and gates.

How is the GDS3702 powered?

It uses integrated Power over Ethernet, so a single network cable supplies both power and the network connection, avoiding a separate mains supply at the door.
