Product Description

The new Centsys G-Speak 3G Wireless Intercom works using a sim card and is compatible with the 3G network. This intercom allows you to operate your gate via a missed call or text and also allows you to talk via your phone to anyone at the gate station. This intercom system does NOT require cable to be run from your gate back to your property.

Main features

  • Smart Phone App – G-Remote
    Access the G-Remote from the iPhone App Store and Android App Store. Customisable features.
  • Wireless convenience
    You know how people are always saying ‘less is more’? Well, when it comes to less wiring, we believe that less is less: less money, less time and less effort, that is! With the G-SPEAK GSM-based intercom system, your phone acts as the intercom handset so there is no need for expensive cable runs back to the house.
  • Up the security ante
    With the G-SPEAK system, you can answer your intercom from anywhere in the world, giving the appearance that you are always home. This greatly enhances security and acts as a deterrent to would-be intruders. In addition, only learned-in, authorised phones are able to access the system.
  • The G-SPEAK  system includes two high-security features
  1. Listen Mode – mutes the microphone at the Calling Module so that you can listen inconspicuously for any activity at your gate
  2.  Talk Mode – use this feature to scare away loiterers at the gate
  • Open your gate from anywhere
    The G-SPEAK offers up to 1500 users the ability to open an entrance gate from anywhere in the world via a free missed call. You don’t need to compromise the security of your home by giving your garden services or repairmen keys or remotes; you can give them limited access even if you’re chilling on a beach in the Bahamas! You are firmly at the controls.
  • Control and Monitor
    With the G-SPEAK  we’re giving you the ability to monitor plus control up to four channels, independently configurable as either inputs or outputs. Now that’s the kind of arithmetic we like!

Receive SMS notifications* on your phone of:

  • – Gate left open
  • – Infrared safety beams obstructed
  • – Alarm activated
  • – Mains failed

Control* up to four different electrical devices via a missed call (free) or SMS:

  • – Open your gate from anywhere in the world
  • – Switch a pool pump on and off
  • – Control a geyser or generator

Easy, fast and secure setup

  • Your voice will be heard!
    And so will the voices of your visitors! G-SPEAK delivers crystal-clear speech quality thanks to state-of-the-art GSM technology.
  • Weatherproof enclosure for greater reliability
    The G-SPEAK Calling Module boasts an impressive IP55 rating, making it perfect for outdoor use. Mother Nature keeps on knocking but she can’t come in – a tough-as-nails ABS plastic housing makes sure of that.

The G-SPEAK Calling Module has an attractive, compact design making for an aesthetically pleasing installation. A white LED backlight makes for beautiful low-light visibility of the Calling Module.
