hi,i want to know how to calculate frame per second in dahua nvr?

i am looking to buy dahua nvr7432-16p and it does not say anything about the FPS on the specification so i need some help understanding how Bit Rate and Record Rate work. i want to use 16 ch for now but in the future i will add more. maybe use all 32 ch. so, i want to know if i use 16 ch, what frames per second will it record at 16ch at 1080p? and will it drop if i add more cameras to it. thanks.
