Based on all of the site survey, carmera, and NVR criteria, you will need to determine your bandwidth requirements per camera. Then determine how your cameras will associate with the HauteSpot master/AP units. In general, you should assume that you can have up to 30Mbps of actual throughput on a single RF channel. This will vary based on distances, interference, line of sight, etc. Use the HauteSpot Wireless Link Calculator v3.1 (Link) to determine the actual throughput given a distance and frequency you intend to use.

HauteSpot Networks uses a TDMA-like protocol which is point to multipoint, meaning that you have a single master/AP unit with several remote station units. So you can add up the bandwidth requirements of all of the cameras that will be associated with a particular master/AP. This can be up to 30Mbps and you should limit the number of cameras to no more than 12 in any case.
