Motion is resetting 15s after firing
For starters - love this plugin. Thanks for making it! I'm new to it, so I'm probably just holding it wrong, but my motion seems to be getting canceled quickly. I'm running `v5.0.16` on Homebridge `v1.4.0` on a RPi4.

```
[25/01/2022, 15:38:50] [CameraUI] VIDEOANALYSIS: New message: Data: [{"zone":"region0","percent":9.139323234558105,"sensitivity":92,"dwell":15,"forceClose":10}] - Motion: detected - Camera: Driveway
[25/01/2022, 15:38:50] [CameraUI] Driveway: Motion ON
[25/01/2022, 15:39:05] [CameraUI] Driveway: Motion OFF - Motion handler timeout.
```

I dropped `dwell` down to 15 from default, but that made no difference. I bumped `forceClose` up to 10, but that made no difference either. It's a consistent 15s from motion on to motion off.
