The SD-2xIn Door and Window Monitor with WiFi is a device for connecting door and window contacts, PIR motion detectors or smoke and gas leakage alarms using dry relay contacts. The device can connect to two independent sensors. For configuration the SD-2xIn has a built-in web server and WiFi connectivity and the device can be remotely monitored over the internet using the SensDesk portal or SensDesk Mobile App (iOS or Android). Using SensDesk the device can send email alerts when the measurements are outside a specified range of values. Text messages (SMS) can also be sent via the SensDesk, if an SMS-GW3 module is attached to the network.
