Currently, the Blink XT cameras are for North America and certain European countries only. We are working hard to release this product in all other countries where Blink is available. Due to the Blink XT cameras being region based - any XT cameras taken outside of these areas will not work. The hardware will not match the existing hardware of an international Blink system. (North American cameras are meant to work with a North American Sync module, etc).
We are going through the process at this time to release the Blink XT in as many countries as possible. This can take time to get the product certifications and pass all regulations for each new country.
We can only send RMA or replacements to customers in countries that we sell Blink XT in. We are very sorry for any inconvenience this may cause. Once the other international models of the Blink XT are released we will then be able to replace these XT cameras that are outside their region.
