Watchmans Clocks
In environments where electricity or computers are not available, the traditional watchman’s clocks can offer you the same accountability as their electronic cousins. Administrators position metal keys in station boxes at important patrol points around the property. The guards carry the watchman’s clock with them on their rounds and insert and turn the key at each location which records a time stamp and location identifier onto a paper roll that can be reviewed later by management; no power or computers needed.
