8. Motion Detection

Anyscene or Babelens app provides an interface named “Motion Detection” to assist user to adjust the motion detected sensitivity. In the V6.01B version firmware or later, Titathink camera had added an option on the web application page of camera to control the Minimum Length of Motion. This option is useful to prevent the false alarm. Want to learn about this master button, see Global On/Off and Motion Detection in Web application. In Anyscene 2.1.1 version or Babelens 1.1.7 version or later, this Minimum Length of Motion was added into Anyscene.

Before you start reading this article, please read 3.11 Configure alarm to record article first.

1. Go to “Alarm Actions” interface


  1. Tap “Advanced Setting” option to access advanced setting interface.
  2. Tap “Alarm Actions” option to access Alarm Actions page.
  3. Tap “Global Setting” option to access Global Setting page.
  4. Enable “Global Alarm” and “Global Task” and enter “1” to Mini Motion Length field.
  5. Back to Alarm Actions page, tap “Motion Detection” to access Motion Detection page.
  6. Enable Alarm On option. This is the main button of motion detection, this button is enabled as default.

 

2. Setup Global Alarm page


  • Global Alarm. It is the master switch to control all alarm settings. If it’s disabled, all alarm setting will be unavailable.
  • Global Task. It is the master switch to control all task settings. If it’s disabled, all alarm setting will be unavailable.
  • Minimum Motion Length. Its range is from 0 to 10. Its unit is Second. This option is used to determine how long the motion last will be considered as a motion activated. e.g. If it’s set to 1, that means a detected motion must last more than 1 second, otherwise, it’ll be considered as false alarm and camera will not be triggered to record alarms.

3. Setup detailed settings of motion detection


  • Window. The Titathink camera offers 4 motion detected windows. User can use it to monitor four areas. The selected window will be actived when the “Alarm on” is enabled. Please note that when an area is covered by two or more windows, the window which is set by high sensitivity will be adopted. For example, an area is covered by window 1 and 2, the Threshold of window 2 is small than window 1, the camera will use window 2 to monitor this area.
  • Alarm On. This button is used to enable the current window.
  • Sensitivity. This option is used to control the motion sensibility. It’s used to represent an area detects the change of pixel. A larger sensitivity value means to trigger an alarm more easily.
  • Threshold. This option is used to control the motion sensibility too. But the Threshold is master switch, the Threshold has the first priority. It’s used to represent the amount of 16 sensitivity. A larger threshold value means more hard to trigger an alarm.
  • Default. This button is used to restore the settings to default.
  • The Red Window. The live view screen is covered by a red zone. That means the available detected area. You can adjust this area with two fingers.

What is the difference between threshold and sensitivity under motion detection, and how to configure them?

How Titathink camera to judge there is a motion? First of all, the camera will collect the image info through camera live view screen. Then the camera will split the live view screen to every little squares. In here, we assume the live view screen is split to 256 squares.

The Sensitivity is used to represent the sensibility of one square. The large value of Sensitivity means the pixels in this square can be detected more subtle changes, so the motion will be more easily detected by this square.

The Threshold is used to represent the area of each 16 squares, so if you setup the Threshold as 70%, that means the motion should be detected by 12 squares (12 / 16 > 70%) that camera will recognize this motion as an alarm, so you can know, if the threshold value is large, it will require more motions or large motion range to meet the value.

For example, the live view screen is spliced by 256 squares, the Threshold is equal to the amount of 16 sensitivities. If the camera want to detect a motion and the threshold is set to 30% and the sensitivity is set to 60%, the camera will judge each square by referring to Sensitivity value. If there have 10 squares covered by the motion and each square of this 10 squares is considered to meet the Sensitivity value, in this case, the Threshold is met.(10 / 16 = 63%). So this motion is detected. Based on the points above, If you want to detect a micro motion, please adjust the Threshold to small value, and the Sensitivity should be equal or greater than Threshold, Otherwise, please alter the Threshold to large value and the Sensitivity should be equal or greater than Threshold as well.
