Bio-scanners are pieces of terran equipment built into installations. They may be accessed externally, though access codes are required, such codes being known only by high ranking personnel. With the right connections however, these protocols can be easily overridden.

Bio-scanners appear to only be capable of registering terran life signs as opposed to organisms as a whole, as they were incapable of detecting zerg within the Flannum Installation.
