If you have a smartphone that you are not using anymore, remember that you must not discard it completely. Why? Well, there are tons of things that you can do with your old buddy. Here is one idea that would allow you to make the most of it.
You can use your old device as Door Bell Video Monitor. For that you just need to install a Wi Fi webcam or smart doorbell out your door and connect it with your phone. Your phone will then work as perfect video monitor which can be placed anywhere in the house where it’s easy to see.
Some of the best smart doorbells that you can use are Ring Video Doorbell, August Doorbell Cam and Sky Bell Video Doorbell and the best webcam you can use is Canary Flex security webcam.
