For a smart security system upgrade, Amazon is offering up to 40% off Ring doorbells and security cameras right now. Amazon's Ring sale includes best-selling video doorbells that will let you see and speak to whoever’s outside your front door.

First-time users should skip overly complicated home cameras and get Blink home security cameras instead. They're so easy to use.

The Blink Mini 2 home security camera is 25 percent off in both colors — black and white — in a deal on Amazon, bringing the already budget-friendly system down to just $30. It can be used indoors or outdoors.

Blink's Outdoor 4 cam occupies a pleasant middle ground as the outdoor security camera that can be utilized in nearly any home.
