A few years ago, I hired an electrician to install a wired video doorbell in my house. He quoted me 1,500 because my house has a "unique" shape and it would require a lot of work to get wiring over there. The following week, I bought a battery-powered video doorbell for 99 and installed it myself in five minutes. You can live out this DIY smart home improvement scenario and save even more money by grabbing the Ring Battery Doorbell for just 55 right now at Amazon. This is the cheapest it has been since Black Friday last year, and a ton of other Ring accessories, including the excellent Floodlight Cam, are also on sale if you want to jump into an entire system.
