Ajax’s security system can use the following connection channels with the Ajax Cloud server and the security company: Ethernet, Wi-Fi, or cellular. The number and the type of connection channels depends on the hub model. If connection is lost on any of the channels, the hub will instantly switch to another channel available.

When several channels are connected to the hub, priority is given to the faster ones: Ethernet and Wi-Fi (connection channels depend on the hub model). Cellular is used as a backup channel and consumes minimum of traffic. It is impossible to change this priority.

The Ajax security system supports connection to Ajax Cloud via all connection channels at once: Ethernet, Wi-Fi, and cellular (channels depend on the hub model). This is necessary to ensure that in case of loss of connection on any of the channels, the hub instantly switches to another channel.

Most of the data is transferred via Ethernet and Wi-Fi, and fewer data is transferred via cellular. It is impossible to change this priority.

Ajax encrypts data using its own proprietary floating key protocol. This protocol is resistant to breaking: even with the power of a supercomputer, it will take years to break the key by a Brute-force search.

Let’s assume a situation where an attacker was able to compromise the key. In this case, the protocol is still protected by the session counter: a new encryption key is generated within each device-hub communication session.

Even if an attacker bypasses the session counter, he will be stopped by device authentication: a secure communication channel is created between the detector and the hub, followed by an ID check.

Each device has a personal ID by which the hub recognizes it.

If the device fails the ID check, the hub will ignore its commands.

Moreover, the hub will detect the loss of the Ajax device that the attackers want to replace with the fake one. The detection time depends on the device type: 3 seconds for wired Ajax devices and the time set in Jeweller settings — for wireless ones. The lost connection notification will be sent to the security company and system users.

The detection time of communication failure with the server depends on two parameters in the Hub settings (Hub Settings Service):

  • Hub-Server Polling Interval. The period of the pings by the Hub to the Ajax Cloud server, is set in the range from 10 to 300 seconds. The recommended and default value is 60 seconds.
  • Deley of Server Connection Failure Alarm. This is the delay required to reduce the risk of a false event of loss of communication with the server. The delay can be adjusted from 30 to 600 seconds. The recommended and default value is 300 seconds.

    The connection delay is activated after 4 failed pings.

The time until the message about the loss of communication between the Hub and the server is generated is calculated by the formula:

(Ping interval * 3) + Connection Delay

With the default settings, the server records the loss of the hub after 8 minutes:

(60 s * 3) + 300 s = 8 minutes

Reducing the time of registration the loss of communication with the Hub can be achieved by reducing the values ​​of the ping interval and the connection delay. But this increases the likelihood of a false event of loss of connection with an unstable Internet connection.
