A:Answer By default, this Night Owl system is set to record when motion is detected by one of the cameras. If a camera detects motion within the cameras field of view, a recording is generated and stored on your microSD card. If enabled, a push alert is sent to your Smart Device via our Free mobile App. Within the App, you can access your recordings for Playback. The gateway can hold up to a 32GB microSD card. Thank you for choosing Night Owl!
