 ### Motion detection
 
-Motion detect is supported for Hisilion/Goke, Ingenic and Sigmastar, the script file needs to be located at:
-`/usr/share/openipc/motion_detect.sh`
+Motion detect is supported for Hisilion/Goke, Ingenic and Sigmastar.
+When a motion event is detected, `majestic` invokes a predefined script 
+`/usr/share/openipc/motion_detect.sh` with parameters specifying the motion
+activity and zone:
 
-The following will be executed on a motion event:
 ```
 /usr/share/openipc/motion_detect.sh [object count] [x coordinate] [y coordinate] [region width] [region height]
 ```
 
-Example script:
+Enable motion detection in `majestic` configuration:
+
 ```
-#!/bin/sh
-echo [$0] [$1] [$2] [$3] [$4] [$5]
+cli -s .motionDetect.enabled true
+cli -s .motionDetect.visualize true
+cli -s .motionDetect.debug true
+cli -s .osd.enabled true
 ```
 
-Final result:
+Reboot the camera and restart `majestic` in the foreground:
+
+```
+killall majestic; sleep 3; majestic
+```
+
+You should see the script running after motion detection events:
+
 ```

+**roi** - region of interest, when we specify one or more regions whose movements we are interested in.

+**skipIn** - on the contrary, if we are interested in movements on the whole screen, except for some areas (for example, there is a tree in the frame, which is swaying in the wind).

+Coordinate format is the same as in osd.privacyMasks: x,y of the top left point, length and width in pixels.
