In advance systems, instead of using a simple button, swipe cards are used. Such cards can be any of the cards that are used in access control. A card can be assigned to a particular guard and this way it can be ensured that only that guard is responding to the alarm. In a still advanced version, proximity cards are used and the recording happens automatically when the guard passes the recording/monitoring post. In larger systems, multiple response units can be interfaced to central recording system. This way, by having multiple response units, it can be ensured that guard actually travels around the building and is not stationary. The reports can be printed from the central unit.

To make systems further tamper proof, instead of cards, the finger prints of the guard is verified at each of the tour recording/monitoring position. Such a system is slightly more expensive and does require additional software and PC's but then for advanced security one has to pay the price.
