What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This door knock sensor detects vibrations when someone knocks on a door and wirelessly transmits a signal to a CentralAlert receiver, which can then trigger flashing lights or other visual/tactile alerts. It's designed for people who are deaf or hard of hearing and can't reliably hear a knock — particularly useful in hotel rooms or bedrooms where a standard doorbell isn't available. The sensor hangs on the inside of the door, so nothing is visible or needs to be installed on the outside, making it a good temporary or travel solution. This is just one piece of the CentralAlert system — you must already own a compatible CentralAlert receiver unit for this sensor to do anything useful.
