Greetings to all. I agree wholeheartedly with you. I use my home's intercom system to play music even when it's over the security of the front door, a fence, or other obstruction. You can attach these to your door locks so guests can open the doors remotely. Even if you don't answer the door, you can still interact with visitors thanks to these techniques. I have always believed in the Indigo Connect system that I use.
