The oncierre system is designed to work in the country of purchase, but it will work in any part of the world, although there are a few points to note:

The hub needs access to LAN/ Wi-Fi network (b/g/n 2.4 GHz).
The hub comes with a power supply whose pin configuration is compatible in the country of purchase. To use it outside the country of purchase you will need to provide your own power supply adapter/ use an additional travel adapter.
The oncierre system is fixed to the time zone of the country of purchase, and all portal data is displayed assuming the residence being monitored is within this time zone.
