For those which have an E1-Zoom camera (or Reolink PTZ Camera), you can access and use features that all the reolink integration (HACS or official) cannot offer (privacy mask, detection zone or video clip… and more). Here the link : PTZ Reolink cameras : HOW-TO use features that aren't available in home automation solutions (like privacy masks, detection zones,..)
EDIT : To use these scripts in HA, use shell_command and the jasonk bash script to do this.
