Howto: Disable cameras via HomeKit when someone is at the location

I had a requirement to disable camera recording when someone is present at a location, and wanted the integration to work with HomeKit. Here is how I archived it:

Prerequisites:

• Homebridge with HTTP Switch plugin (https://github.com/Supereg/homebridge-http-switch#readme)
• Setup NX to accept API calls via Cloud (https://support.networkoptix.com/hc/en-us/articles/360016266074-Cloud-API-Route-API-Calls-via-Nx-Cloud)

In HomeBridge, create a HTTP-Switch with something like; which will either enable/disable the scheduleEnabled which stop/starts recording for the camera(s). 

Then within HomeKit (I'm using Home+ 5) you simply setup your automation to turn on/off the switch. In my case I'm doing a "If anyone is at location, turn below switch off" and "If everyone has left location, turn switch on".
