Between each camera to the NVR:
In open space we tested 350m (1150ft) working distance;
With normal obstacles like 1-2 walls, we tested 35m (115ft) working distance.
For distance we only have theoretical values.
No certain distance can be guaranteed due to different environments applied in.
It varies depending on obstacles and signal interference.
On the contrast, if there are many blocks and signal interference between, the distance could be closer.
If this can't help you, please feel free to contact us.
