Stay on Lookout

Use the left button to select the camera - front or rear. Position the phone so that the area to be guarded, such as a door or a hallway, is in the camera's field of view. Press the right button, and the app will be ready to work in 7 seconds. At this point, the buttons on the screen will turn white. When a moving object appears in the phone's camera's field of view, an alarm will sound. The number at the top of the screen shows the "amount of movement" in the phone's camera's field of view. If this number becomes greater than the threshold value indicated at the bottom, an alarm will sound. You can change the threshold value using the plus and minus buttons. The app can react to changes in lighting in the room, to the movement of shadows and spots of light even outside the camera's field of view. If this happens, you should reduce the sensitivity by pressing the plus button. If you don't want others to see that your phone is in guard mode, press the second button from the left and almost the entire screen will turn black. To turn off this mode, double-tap the screen. If you don't want others to hear the alarm, use Bluetooth headphones. To pause the app, press the right button. The app uses quite a lot of power, so it makes sense to keep your phone connected to a charger.
