Anker eufy Security Wireless Siren – 105 dB, IP65, HomeBase Required, 2-Year Battery Life

The eufy Security Wireless Siren is a loud, easy-to-install deterrent for the eufy Security ecosystem. A 105 dB siren makes sure the alarm is heard when a security threat is detected, indoors or outdoors.

It pairs with a eufy HomeBase (compatible with HomeBase S380 and S280), connects through the eufy Security app for remote alerts and battery status, and installs without tools or professional setup.
