This door monitor is crafted to deter wandering. Its entry chime feature notifies individuals whenever someone enters or exits the home. Installation is effortless, thanks to the provided self-adhesive pads, and the sensors can be positioned on either side of the siren for enhanced convenience. Additionally, it includes an entry chime setting that alerts you to the movement of people or children while you're at home. Changing between off, chime, and alarm modes is simple with the low battery test button, and batteries are included for immediate use.
