Home security is no longer just about making sure you lock your doors and windows. Thanks to the development of Internet of Things (IoT) devices, we can now monitor our homes in real-time, no matter where we are, and make use of everything from motion sensors to video doorbells. 

It's not often that these devices come cheap and it can be expensive to start up a home security ecosystem. However, if you're willing to compromise a little -- such as by picking up a refurbished model instead of a brand-new product -- prices can substantially drop.

One such deal is available. Over at Amazon, you can pick up a 2021 model of theRing video doorbell for just under$35, a discount of$20, or 36%.
