Jeweller and Wings communication protocols
Range extender uses Jeweller technology to transmit alarms and events and
Wings to transmit photos. These are two-way wireless data protocols for data
transmission that provide fast and reliable communication between the hub,
range extender and system devices connected to a range extender.
The protocols support block encryption with dynamic key and device
identi cation at every communication session to protect against sabotage and
spoo ng.
To control communication with system devices and display their statuses, the
Ajax app provides a "hub — devices" polling system with an interval of 12 to 300
seconds. The polling interval is adjusted by the user or PRO with admin rights.
