To change your device's settings, log into your Zmodo account on your smartphone through the Zmodo app. You will find your device's settings in the home screen by tapping the gear icon in the upper right of that device's listing. You can then enable and disable various features, set schedules, and view information about your device.
You can also access your device's settings by logging into user.zmodo.com and choosing the gear icon when you mouse over your device (or click the gear icon when viewing the live video). As some settings can only be changed via the app, the list of settings on the web view is slightly abbreviated.
