Stay aware of every visitor with a door monitoring system designed for people who are deaf, hard of hearing, or living with mild to profound hearing loss. Loud sound, clear light indicators, and strong vibrations help ensure you never miss someone at the door, day or night.

This preassembled bundle includes the Door Transmitter, Portable Receiver, and Bed Shaker. Setup is simple and requires no Wi-Fi or pairing. Everything works right out of the box.

When a visitor rings, the Door Transmitter listens for your existing doorbell chime and sends a wireless signal to the Portable Receiver. You are alerted with your choice of loud sound, a flashing visual indicator, or vibration through the included Bed Shaker.

The Door Transmitter sits next to your existing door chime and is preprogrammed to recognize most residential chimes. You can also teach it to detect additional sounds such as intercom buzzers, medical devices, pumps, or other audible alerts around your home. This gives you versatile coverage for more than just the front door.

The Portable Receiver is compact and easy to use, with adjustable volume control and a bright LED indicator. It runs on long-lasting batteries that provide dependable operation for everyday use, and when connected to the Bed Shaker, it can wake you at night with powerful vibrations.

This bundle can be used on its own or as part of the Bellman Alerting System. It is fully expandable. Add transmitters for phone calls, smoke alarms, or carbon monoxide alerts at any time with no extra setup.
