A security apparatus for a portable electronic device includes a cable having a length, a first end, and a second end. The security apparatus also includes a lock head coupled to the first end of the cable. The lock head is configured to selectively engage the portable electronic device and is movable by the cable between a first position, in which the lock head is secured to the portable electronic device, and a second position, in which the lock head is unsecured from the portable electronic device. The security apparatus further includes an actuator assembly coupled to the second end of the cable and spaced a distance from the lock head along the length of the cable. The actuator assembly is operable to actuate the cable to move the lock head between the first position and the second position.
