The move came under heavy criticism from groups like the American Civil Liberties Union (ACLU), who said the company's Rekognition software guide "read like a user manual for authoritarian surveillance".
However, Amazon has hit back and said in a statement: "Our quality of life would be much worse today if we outlawed new technology because some people could choose to abuse the technology...
"Imagine if customers couldn't buy a computer because it was possible to use that computer for illegal purposes?"
It argued that the technology has been used in the past to find missing children, and that there was great potential when it comes to fighting crime.
However, ACLU's technology and civil liberties attorney Matt Cagle has warned about the potential "harms" such developments could do.
He told the BBC: "When powerful surveillance technologies are deployed it is difficult and often impossible to undo the harms once those technologies are deployed in communities.
"And so we're very concerned that Amazon appears to be rushing into this surveillance market with and with no meaningful restrictions to limit how governments can use this and local governments themselves and local law enforcement are not adopting their own restrictions."
