Zmodo Pivot Door / Window Sensors (4 Pack) Description The Zmodo door/window sensors work with the Zmodo Pivot to protect your home and peace of mind. After setting up your Pivot, you can add the sensors in the Zmodo app and create preset directions for where your Pivot will turn when each sensor is triggered. The sensors connect wirelessly to the Pivot to send you alerts on your smartphone when one is opened or closed. You can also schedule alert notifications in the app. The sensors are easy to mount with their adhesive backing and have a battery life of up to 1 year when triggered 10 times per day (batteries can be replaced easily by customer as needed). Please note that these door/window sensors require a Zmodo Pivot to work and are not compatible with other smart hubs. The mobile phone must be on the same network during the connection process. If the customer's phone has more than one WiFi network memorized, then the customer's phone might switch networks during the setup process. The customer should receive an error message when this happens.
