Trying to improve low light recording

[pastytustle]

I have a few cameras set up to monitor the front of the house, during the day the quality is spot on but when it's dark, it becomes almost impossible to pick out any detail on anything that is moving. Static object are clear, but anything moving is blurred or just ghosts across the screen. from my own research it seems that shutter speed is a major factor in the quality of night time footage, but I cant seem to get any improvement from my tweaks.
I've attached some screenshots of the system and the setting available, if anyone can give any advice that would be greatly appreciated.

I don't recognise the camera make/model from the user interface.
It's not one we offer / have experience with, so I can't comment on many of those settings they offer.
But your basic understanding is correct; by manually fixing a slower shutter speed the shutter is effectively open for longer and lets more light in so it performs better in low light.
But, as you have experienced, the longer the shutter is open the worse the motion blur effect that you will see.

Essentially, the default settings that the manufacturer sends the camera out of the factory with will be the best performance they can achieve,
Very often these tweaks will make only very minor differences.
With experience you can see pretty quickly whether a camera performs well in the dark or not - no amount of tweaks will make it good if it is not.

If the camera does not perform well in the light available, then often the best option is to - 'add' light.
You might not need a lot of light.
And LEDs nowadays allow us to add light overnight at a very low running cost.
