I hope I am not off topic but I need some help in determining what to do to fulfill a need.
I need to place a push button (or other signaling initiating device) at one to three doors and have it communicate with a portable receiver giving silent, visual, vibration, and possible audio indication. If audio is included I need to be able to turn that signaling on and off. The receiver has to be somewhat "foolproof" requiring no adjustments. This will be an "RF" system of some sort with a required range of about 200 feet max. The receiver will be small enough so it can be placed in a pant pocket. Only one receiver is required however a backup would be wise.
The "push button" can be wired but it would simplify installation if it were battery powered. But, battery power has its' own drawbacks, i.e. nobody ever checks the batteries and it will be out of power but everybody will think it is working etc.
What comes to mind is a system similar to what is used in restaurants where they give the customer a disk about 4 inches in diameter and you place it in your pocket and roam around the property. When you can be seated, the disk vibrates as well as lights up etc. The disk can then be placed on a charging station and is always ready for the next usage. Maybe a system like this can be adapted.
Any suggestions????
