Abstract: A security system control module with a portable housing including a wireless receiver, control circuitry, nonvolatile memory, and a data connector. The receiver receives data transmissions from at least one wireless security device that monitors a condition of a premises in which the wireless security device is installed. The data connector exchanges data between the control circuitry and an external host device, and it also accepts from the external host device primary operating power for operating the wireless receiver, the control circuitry, and the nonvolatile memory. The control circuitry is adapted to process signals in accordance with a preprogrammed configuration file stored in the nonvolatile memory, the signals received via the wireless receiver from a wireless security device, and to communicate with an external computer located remotely from the external host device via the data connector using a first communications protocol.

Abstract: The invention relates to a surveillance device for installation in a domestic property, comprising event execution means and processing means for generation of commands for at least one event reaction body, characterised in comprising a network (6) of cooperating non-hierarchical modules (1,2,3,4), each comprising detection data processing means (8) and internal communication means (9), configured for exchange of surveillance data between modules. The invention further relates to a surveillance installation comprising several such devices.

Abstract: This process for validating/invalidating a message (4) sent over a information transmission network between at least two stations connected to said network by means of a response in a communication frame, the message including at least one header field (5) sent by a first station and one data field (6) sent by a second station, is characterized in that the data field (6) includes an end of field marker (7) and a beginning of field marker (8), modified in a manner that respectively corresponds to the beginning and to the end of an operation to update the remainder of the data field (6) carried out by the station concerned, to enable the message (4) to be validated if the two markers correspond and to be invalidated if they do not agree.
