This device is a wireless transmitter that goes inside the door of the mailbox and a receiver that plugs into a 110 volt outlet in the house. When the door of the mailbox is open, a momentary chime in the house is followed by a visual continuing green light to inform you that the mailbox has been opened, either by delivery, by an intruder. Then the reset button should be pressed after you have picked up the mail.
It also signals if the mailbox has received an impact such as by a “mailbox baseball vandal.” Transmitter range is a nominal 150 feet (45 meters). The transmitter operates day or night, regardless of the weather.
This is an ideal gift for seniors who are anxious for mail and who don’t wish to make unnecessary trips to check whether mail has been delivered or picked up. For Christmas or other special occasion or just to say “Thanks, we love you,” this fits most gift budgets.
An Announcer/Tattler™ plus a BatGrabber™ may allow you to call the sheriff quickly and to nab vandals on the road
