Amcrest Camera Mass (Bulk) Video Exporter with Web Browser Console

amcrestVideoScraper.js

/// How it works :
/// This script will download videos from your Amcrest Camera automatically (automate cumbersome task of individually clicking download on each video)
/// Limitation is that it will stop downloading when it reaches the end of the month.

/// HOW TO USE :
// 1. Login to Amcrest camera and click Playback tab.
// 2. Select Day of the Month to begin downloading from.
// 3. Open the Web Browser Console. (CTRL + SHIFT + C on Mac)
// 4. Paste this entire script in the execution field and run it.
// 5. You will see the files start downloading.

// Your browser may warn about "Multiple Files Download", Allow it to do this.

In firefox don't forget to turn off "Always ask where to save files" first! (and thanks for the script!)
