A battery operated door alarm system that has a receiver you can put in your pocket when downstairs or in the yard. Amazon has many but I can't figure out if they are what I'm looking for. Thanks.
I recently had a Ring doorbell installed. With the alert setting on, my phone chimes when someone opens the door or comes up to the front door. And I can go on the Ring app to see who it is. I also have a Ring camera in our bedroom and in our family room so I can see how my husband is doing when Iām outside. Big help.
