1. A access control system, comprising:
a catch configured to be affixed to an inner portion of an enclosure;
a latch configured to be affixed to an inner portion of an access door of the enclosure and to engage the catch when the catch is attached to the inner portion of the enclosure and the access door is in a closed position, wherein the latch engaging the catch secures the access door of the enclosure in a locked state;
a housing configured to be affixed to an outer portion of the access door opposite the latch, the housing comprising:
a memory device;
a latch controller configured to detect when the latch is no longer within a predetermined proximity of the catch; and
an emergency access portal aligned with and providing access through the access door by an instrument to at least the catch to engage the catch,
wherein engaging the catch with the instrument releases the access door to provide access to the enclosure and triggers the latch controller to detect that the latch is no longer within the predetermined proximity of the catch, and to register an opening of the latch in the memory device.
