The Intelligence Hub is owned by scOS and loaned to you while you subscribe. It is not a product you buy and then return.
There is no separate fixed-term warranty. While your subscription is active and the Hub has been reasonably cared for, if it is faulty we repair it (with a software update where that will fix it) or replace it, at no extra charge. That promise lasts for as long as you subscribe, and it sits alongside your statutory rights under the Consumer Rights Act 2015, which are not limited to 12 months.
If you are a new consumer who signed up at a distance, you also have a 14-day cooling-off right. After that you can cancel at any time; the service runs to the end of the paid period. You return the Hub within 14 days of cancelling (we prefer to collect it), and there is no charge if it comes back in reasonable condition.
Cameras are yours, or a third party's. Their warranty is the manufacturer's, not ours.
The full terms are in the Service Agreement and Cancellation & Hub Returns.
