The File Watcher device monitors a folder on the agent host and raises triggers when files appear or disappear. It’s a powerful way to start rules from external systems — for example, reacting when a recording or export lands in a watched directory.

​
Connection

The File Watcher runs on the agent host and watches the local file system. Configure:
  • Watch folder — the absolute path to monitor on the agent machine
  • File filter — limit to all files, video, or images
  • Watch mode — automatic (use OS file events where available, otherwise poll) or polling, with a configurable poll interval

​
Commands

  • Refresh — force a rescan of the watched folder

​
State and triggers

The device reports state about the watched folder, including whether it’s active, the folder and filter in use, the watch mode, the current file count, and the total size. It raises triggers your rules can react to:
  • File added
  • File removed
Trigger data includes the file name, full path, extension, size, and last-modified time for use in rule actions.
