An access control device including an electromagnetic lock module for selectively locking and unlocking a door in a door frame is provided. The access control device provides a lower profiled electromagnetic lock module to improve the aesthetics and functionality of the module, supports and integrates modern accessories such as CCTV, CCD cameras, passive motion detection with automatic background correction, digital notification display, automatic source voltage selection, door and lock status indicators, and ease of installation. The present invention further provides components and circuitry to enable connection of the electromagnetic control module to 12 or 24 volts DC or to an unfiltered rectified AC power supply.

A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base, a stabilizing element extending axially from the base, and a movable engagement element partially contained within the stabilizing element. The stabilizing element includes a first end adjacent the base and a second end opposite the first end. The movable engagement element extends from the first end of the stabilizing element to the second end of the stabilizing element. The movable engagement element is movable between an unlocked configuration, in which the movable engagement element is closer to the stabilizing element and the locking head is insertable into the portable electronic device, and a locked configuration, in which the movable engagement element is further from the stabilizing element and the locking head is secured to the portable electronic device.

A security apparatus for securing a portable electronic device to an immovable object includes a locking head having a base and a plurality of engagement portions extending from the base. The plurality of engagement portions is configured to be inserted into an aperture of the portable electronic device. The locking head also includes a linear portion positioned between the plurality of engagement portions and extending from the base. The linear portion is twistable about its length to move the plurality of engagement portions radially outward. The security apparatus further includes a security device attached to the locking head and configured to engage the immovable object.

A security apparatus for a portable electronic device includes a locking head having a base and an engagement element extending from the base and adapted to be inserted into an aperture of the portable electronic device. The engagement element includes a wedge-shaped engagement portion configured to engage part of the portable electronic device when inserted into the aperture. The locking head also has a stabilizing element extending from the base and slidable along a side of the engagement element into the aperture of the portable electronic device, thereby inhibiting the engagement element from being removed from the aperture. The security apparatus further includes a security device attached to the locking head and configured to engage the immovable object.
