### 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:
To test the motion detection, create a simple script that echoes the parameters to the output:
```
#!/bin/sh
mkdir -p /usr/share/openipc
echo "#!/bin/sh
echo [$0] [$1] [$2] [$3] [$4] [$5]
" > /usr/share/openipc/motion_detect.sh
```
Final result:
Enable motion detection in `majestic` configuration:
```
cli -s .motionDetect.enabled true
cli -s .motionDetect.visualize true
cli -s .motionDetect.debug true
cli -s .osd.enabled true
```
Reboot the camera and restart `majestic` in the foreground:
```
killall majestic; sleep 3; majestic
```
You should see the script running after motion detection events:
```
