Overview The DCH-S220 mydlink Wi-Fi Siren is a wireless siren that helps keep your home safe. Pair the siren with the mydlink Wi-Fi Motion or Water Sensor (DCH-S150/DCH-S160) so when either motion or water is detected, you can be notified. When the siren is triggered, it will generate a 100 dB (max) audio alarm and it will send push notifications to your smartphone so you know what is going on at home from anywhere. Works well with other D-Link Connected Home Devices The mydlink Wi-Fi Siren can be used with other D-Link Connected Home devices such as a water sensor ot a motion sensor, so you can customize your own home automation system to fit your needs. Install a DCH-S150 motion sensor and as motion is detected, the siren will go off to alert you of a potential danger. Easy Setup The DCH-S220 can be easily set up. Download the free mydlink Home app and follow the step-by-step instructions to quickly configure the DCH-S220.
