The Ring Wi-Fi Enabled Video Doorbell provides some useful features.
You can see and speak to visitors using your smartphone or tablet, whether you’re upstairs or across town.
Not everyone rings the doorbell, so the doorbell includes motion sensors to alert you of activity at your home. The sensor can detect movement up to 30 feet away. HD video recording stores all recorded footage to the cloud (it connect to your network via wifi).
I have thought about such a product since long before I ever heard of wifi (or “the cloud”). Back then I envisioned being able to see who it was and decide if I wanted to answer the door or not.
I also like the security feature of having a record of who comes to your door. If someone tries to “case” your house and check to see if you are there by ringing the doorbell, you will have a record of it (and see it in real time, wherever you are).
The doorbell can tie into existing electricity or operate using a battery.
You could rig something that does this yourself for less (it costs $199 now) but this product lets you get something up and running easily. That is actually what I figured I would do when I returned to my own house (I am busy living the nomad life for now).
