I don’t know about you, but I would love to get notified every time my mail is delivered. The Mail Chime Wireless Alert System can help. It is a smart kit with a sensor and receiver that beeps when it detects activity. It lets you know when you have new mail or someone is tampering with your mailbox. The device has a range of 450 feet.
The device lets you adjust its volume. You are also provided with a visual notification in form of a bright LED light. You can find out more information here.
