TASK: Have a read of this article about cameras in the home. There are some benefits maybe but the risk of streaming video and audio from your home to a random company on the internet I think are obvious.
If you do really need a home camera system, take the time to set one up that you can control, that connects just to your servers and not another companies.
WHY: Even if the company that runs your security system/smart home is ethical they can be bought out by one that is not. They can also have a disgruntled employee that could sell your footage. Just dont take the risk.
