A rotation detection system for detecting the rotation of a lock dial includes a magnet coupled to the lock dial to generate a changing magnetic field in response to rotation of the lock dial, a sensor disposed near enough to the magnet to detect the magnetic field and provide a sensor output signal indicative of the magnetic field, and a controller coupled to the sensor for receiving the sensor output signal, the controller providing a controller output signal in response to a change in the sensor output signal. An alarm interface can receive the controller output signal and provide an alarm signal.

Universal door lock indicating devices, kits, and methods are described. The kits and devices can include a compartment designed to be attached to a door and be disposed outside a deadbolt base, a sensor disposed within the compartment and designed to detect whether a deadbolt lock turnpiece installed on the deadbolt base is in a horizontal or vertical position, and a wireless transmitter disposed within the compartment and operatively connected to receive output from the sensor. The methods can include receiving a wireless transmission from a device of the disclosure, and outputting the locked or unlocked status of a deadbolt based upon information in the wireless transmission.

A security device is provided including a security lock configured to retain an object when locked, a receiver configured to receive a security code transmission, and processing circuitry configured to transition the security lock between a locked state and unlock permissive state based on receipt of a security code. The security lock may initially be set to the unlock permissive state. At the first instance in which a security code is received, the processing circuitry may transition the security lock to a key permissive mode in which the security lock transitions to a locked state and in response to a subsequent receipt of the security code the security lock transitions to the unlock permissive state.

Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.

An apparatus for detecting the position of window handles or door handles, the apparatus including a magnetic-field sensor and a microcontroller unit, the microcontroller unit being designed to read out data from the magnetic-field sensor, to record a magnetic fingerprint for at least one window-handle/door-handle position, and to detect the at least one window-handle/door-handle position by comparing data of the magnetic-field sensor with the recorded magnetic fingerprint. An operating method for such a window handle or door handle is also described.

In some embodiments, a method of determining whether a door is ajar may include determining an orientation of a door lock of the door, and, based on the orientation of the door lock, analyzing at least one signal from at least one of two or more proximity sensors of the door lock. The method may further include determining whether the door is ajar based at least in part on a result of the analyzing of the at least one signal. In some embodiments, a method of determining a status of a door may include receiving a first signal from a first magnetometer disposed within a door lock of the door, receiving a second signal from a second magnetometer disposed within the door lock of the door, and detecting, based on a result of an evaluation of both the first signal and the second signal, a possible attack on the door.
