An electronic door lock including a magnetometer, an accelerometer, and a processor. The processor is configured to determine a status of a door with respect to a door frame using data provided by the accelerometer and magnetometer which collectively generate acceleration data, velocity data and positional data of the door. The processor provides data to a user interface or an alert device indicating one or more of: door open angle, prep-less door position, an acceleration alert, a door position alert, door sag, door frame rub, and triangulation of an intruder.

A system to detect an unauthorized attempt to open a security lock (1-6), the system comprising a camera (10), which is directed towards the vicinity of the security lock; a communications connection between a camera (10) and a predefined mobile station (13); and a detector or sensor (8, 9), which is arranged to start the camera for transmitting a picture via said communications connection to the mobile station. The system further comprises a safety device (6) of the lock, having a safety latch (16), which has a locking position and an opening and, in which locking position, the mechanical opening of the lock with a key and/or rotary knob is prevented; at least one detector or sensor (8, 9), which is located in connection with the lock or door and arranged to detect at least one of the following events: (i) the presence of a key in the key channel (4) of lock, (ii) a movement or vibration of the door, (iii) a movement or vibration of a part of the lock. The control unit (7) of the safety device (6) is arranged to start the camera (10), when the detector or sensor (8, 9) detects one of above said events. The control unit (7) is arranged to start the camera (10) automatically only if the safety latch (16) of the safety device (6) is in the locking position and the detector or sensor (8, 9) detects one of above said events.

A door lock mechanism is disclosed that includes door lock and alarm features. The mechanism includes a controller and a sensor useful to detect motions that are representative of attempted access through a door to which the door lock mechanism is attached. The controller can set an alarm condition if a measured motion, such as a measured acceleration, meet and/or exceeds a threshold. If an appropriate access control credential is provided through a user device then the alarm condition may not be set by the controller. The door lock mechanism can be coupled to a remote station via a communications link if needed, such as a radio frequency link. The remote station can additionally be in communication with the door lock mechanism via a network. The remote station can be used to send and receive messages regarding door lock mechanism status, configuration, etc.

A door assembly includes a door panel connected to a door frame and pivotable about a pivot axis, a door latch coupled to the door panel and operable to selectively inhibit movement of the door from a closed position to an open position, and a sensor coupled to the door latch and operable to detect acceleration of the door and output acceleration data corresponding to the acceleration of the door panel in a first direction. A controller is coupled to the door latch and the sensor. The controller is operable to analyze the acceleration data to determine the cause of the acceleration.

An electro-mechanical lock for cargo containers or similar enclosed spaces such as storage units. The locking mechanism includes a dual-ratcheting mechanism, which is normally in the locked position, and which firmly secures doors of a container or other enclosure. To unlock the device, the user obtains a temporary access code and unlocks the device, either by a wireless interface or by, for example, a key pad. The device incorporates a rolling access code algorithm that changes the access code based upon a pre-defined customer selected time period during which the code is valid. Once the validity period expires the user must obtain a new access code from a secure access code source to unlock the device. When access is desired, the user contacts a remote secure access code source, which provides the access code for the associated lock and time period.
