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 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.

Methods and systems are disclosed that, in some aspects, provide an opening mechanism comprising an interior and an exterior door handle and sensors to detect movement of each door handle. A door position sensor may be provided. An alarm module for generating an alarm may be connected to at least one of the sensors. A method may include receiving a door handle actuation signal, determining whether the door handle actuation signal is from an inside door handle or an outside door handle and performing a function. One or more methods include determining an event, including an attempted entry, a forced entry and an incomplete entry.

In order to secure a door in a locked (or locked open) position without a key, such as to resist a forced entry through the door, a removable, remotely-controlled door locking apparatus is provided, which includes a rear plate for attachment against a surface of a door, a cover for enclosing components on the rear plate, and a telescoping arm assembly connected to the rear plate and extendible so that the other end attaches to a door knob. A DC-powered linear actuator connected to the rear plate and at least one electronics module configured to communicate wirelessly is within the cover. A foot of the actuator is configured to be extended in a lock state against a floor surface to secure the door or retracted in an unlock state, based on a wireless signal received from a remote smart device to control the actuator.

A sliding window and door lock including: A housing, where the housing is attached to at least one of a window sill and the floor next to a sliding door; a pivoting latch and a pivot, where the pivot attaches the pivoting latch to the housing, where the pivot is located farther along the path of travel of the at least one of a sliding window and sliding door when the housing is mounted to the at least one of a window sill and the floor, wherein the pivoting latch is adapted to pivot from being flush with the edge of the housing into the path of travel of the at least one of a sliding window and a sliding door, wherein the edge of the pivoting latch interfaces with the at least one of a sliding window and a sliding door, wherein the force of the at least one of a sliding window and sliding door would be obstructed by the pivoting latch being forced into the pivot. The sliding window and sliding door lock is preferably designed to at least one of 1) provide a lock to obstruct the opening of either of a sliding window and a sliding door, 2) prop open either of a sliding window and a sliding door, 3) create an alarm if an intruder attempts to open either of a sliding window and a sliding door.
