I've been trying to reconfigure a Dahua 5442 camera stream / substream but when I log into the camera, go to the Video page, all of the dropdowns such as encode mode, resolution, frame rate, bit rate are empty (no values), and when I toggle them the dropdowns are also empty, not letting me change any value.
I've tried resetting to defaults, saving, manual reboot etc and can't seem to get the dropdowns to show any values.
They definitely did work and show values before because I remember configuring them. Since then I haven't touched the settings.
Does anyone know why this might happen? I'd rather not take the camera down to do a factory reset if I can avoid it.
