To apply changes: # Cameras
Camtiler is the umbrella name for our homegrown camera surveilance system.
Everything besides [Camera](#camera)s is deployed with Kubernetes.

### 📸 Camera
Cameras are listed in [application.yml](application.yml) as `kind: Camera`.
Two types of camera hosts:
- GL-AR150 with [openwrt-camera-images](https://git.k-space.ee/k-space/openwrt-camera-image).
- [Doors](https://wiki.k-space.ee/e/en/hosting/doors) (Raspberry Pi) with mjpg-streamer.
### camera-tiler (cam.k-space.ee/tiled)
Out-of-bound, connects to cameras and streams to web browser.
One instance per every camera
#### camera-operator
Functionally the same as a kubernetes deployment for camera-tiler.
Operator/deployer for camera-tiler.
### camera-motion-detect
Connects to cameras, on motion writes events to Mongo and frames to S3.
### cam.k-space.ee (logmower)
Fetches motion-detect events from mongo. Fetches referenced images from S3 (minio).
#### camtiler-event-broker
MitM between motion-detect -> mongo. Appends S3 URLs to the response.
