That's one way to do it, lol. Another way to get motion detection from a camera into Hubitat is to run another piece of software locally. Most people around here run Blue Iris, and you don't need any extra hubitat app to integrate motion sensing. If you want more than motion sensing you can use this app:
It works very well, Blue Iris allows for lots of customization around motion detection sensitivity and parameters. Once it senses motion it sends a local end point trigger to Rule Machine and then you can do whatever you want in RM. When my camera senses motion near the back door, it takes about half a second for Hubitat to turn the back door light on.
Blue Iris software has an immense amount of features and is the go to software for running cameras locally.
Amcrest doesn't make their own cameras, for the most part they just rebrand Dahua cameras.
