If it is onvif compatible or similar sure, but it’s most likely not. If you’re lucky someone else have had the same camera as you and made a custom firmware for it, but I wouldn’t count on it.

Frigate and shinobi are two alternatives to use software wise on the server, but you still need a compatible camera.

Theyre not. Since there is optical fiber involved (laser) the light inside white cables work better in a bright environment, there will be less light attenuation leaking out. The reverse is true in a dark environment, dark cables will block more light keeping it inside of the cable, leaving more data intact without loss.
