Does this record 30 fps?

This NVR Frame Rate is 4CH@25fps (PAL), 4CH@30fps(NTSC）

How is the nightvision on these compared to the 5mp ones?

Hi,they have same nightvision distance about 65ft-100ft.

Will onvif ever become available for the 4k cameras in this package?

Dear, the 4K camera B800 doesn't support ONVIF.

Do the cameras have to be connected directly to the nvr, or can 3 cameras be connected to a switch and then run one cable back to the nvr?

Right, although MAKE sure those switch(s) are POE. If you buy a cheap switch that does not support POE, you'll have to power the camera via barrel male power connector (12v 2amps) so that's 24w per camera (if I'm not mistaken, could be over 1amp making it 12W) volts x amps = watts (MhA to mA 1000 = 1mA)
