Four employees of Amazon's home security company Ring have been fired after being caught snooping at users' videos.

Axar.az reports citing Infosecurity that the online retail giant admitted terminating individuals over unauthorized access in a letter dated January 6 that was addressed to US senators Ron Wyden, Edward Markey, Gary Peters, Chris Van Hollen, and Christopher Coons.

In the letter, Amazon states: "Over the last four years, Ring has received four complaints or inquiries regarding a team member’s access to Ring video data. Although each of the individuals involved in these incidents was authorized to view video data, the attempted access to that data exceeded what was necessary for their job functions.
