Good news for anyone looking for a security camera to keep an eye on their property; Amazon slashed the price of the Blink Mini Indoor Security Camera by a third, bringing it down to just $19.99 from $29.99. This is the best deal we've seen for the home security camera, beating out the prices we saw on Black Friday and Cyber Monday last year, making it an incredible value and we won't see perhaps a better. price in the official market. Amazon Black Friday sales. The best home security cameras can be an expensive purchase, so an offer is always welcome. If you want a home security camera before the holiday season begins, we recommend closing this deal now due to ongoing supply chain issues.
