How far can I extend the expansion modules using the CAT5 cable? Is the total run length from the base units or is it between the expansion modules and what is the data transfer rate?

AKCPsecurityProbe Series, Support

The maximum run length of the expansion modules is 1000 feet. This is not the total run length. This is between the base unit and the expansion modules, or from each expansion module. The data transfer rate is 115.2K BPS (bits per second).
