Which protocol is used to connect the hub to the Central Monitoring Station (CMS)?


Ajax hubs communicate events to the Central Monitoring Station (CMS) using the Contact ID protocol.

The data is transferred in two stages:

  1. From the Hub to the Ajax Translator software installed on the security company’s computer — in digital format protected from interception and fraud.
  2. From the Ajax Translator to the CMS — in the SurGard shell of the Contact ID protocol.

Channels for transfer of events from the Hub to the Translator

Hubs can send events to the Translator via several communication channels:

  1. Via the Ajax Cloud server.
  2. Using both communication channels while the server will serve as a backup channel.
  3. Directly to the CMS — bypassing the server.
