Allow passthrough of api call to camera

[Xelaph]

Describe what you are trying to accomplish and why in non technical terms
I want my camera's to be on a separate physical network from the normal network for security reasons. We have a Hikvision doorbell and to locally detect if the button of the doorbell is pushed, you can curl a request to camera_ip/ISAPI/VideoIntercom/callStatus?format=json. I'd like to automate this using Home Assistant, so I can get a notification if the doorbell is pushed. Currently this is possible because the doorbell is on the same network as my Home Assistant instance, but in the future I want to put the cameras on a separate network.

Describe the solution you'd like
The ideal solution is an option to pipe api calls for the camera through frigate to the camera. I don't know if this is possible.

Describe alternatives you've considered
An ability to read this through MQTT would be a great alternative.

Additional context

This doesn't seem like something that is actually a frigate use case, more like something for home assistant that wants to be channeled through frigate due to a desired network topology

My suggestion, @Xelaph, would be to run a tiny proxy on whatever box you use for Frigate. If you're using Docker, for example, you could spin up an NGINX container that can relay only specific calls (such as your callStatus endpoint).
