For places where there are humans that guard the place (e.g. a security guard, doorman, gate keeper). Normally used in conjunction with barrier=* to note further detail about a barrier.
- barrier:personnel=yes there is usually a human there (e.g. to open a gate or control access permissions), (use with a temporal condition where applicable). If the human is required to pass the barrier, use additional instead of yes.
- barrier:personnel=no as far as you know there is no guards (use with a temporal condition where applicable)
- barrier:personnel=additional you must pass the human (automatic access control alone doesn't get you in)
- barrier:personnel:operator=operating security company or police / military
