If you want some added security within your home, you should look into getting a remote doorbell that you can easily install at your gate. This will allow you to find out who is at your gate without having to peek through the windows or leave your home.
Install the Chimes
The first thing to do is to take your chimes and install them in your home. All you need to do is mount the chime to the wall with a small screw and then plug it in. If you are using multiple chimes, then ensure that you place them strategically within your home.
Once the chimes are set up and plugged in, you can then go out to your gate and start installing the switch. Place the switch in a spot where someone is going to be able to see it, typically on the actual gate or on the wall next to it. Most of the switches that you find will use an adhesive, or screws.
Give it a Test Run
Once you think you have everything ready, have one family member stand in the home while you stand outside and push the bell. This will allow you to make sure that you have installed everything properly
