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.

Disclosed are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also disclosed are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

A covering (200) for an opening in a building and a sensor assembly (500) is disclosed. The covering (200) comprises a panel (201) moveable between an open position and a closed position, and to an intermediate position between the open position and the closed position. The sensor assembly (500) is configured to sense the position of a locking member (205) of the covering and to transmit signals indicating the position of locking member (205). Methods of installing a sensor assembly (500) on a covering (200) of an opening of a building are also disclosed.

ASSEMBLY AND CONTROL SYSTEM FOR ACCUMULATORS IN WORKSTATIONS, presenting a system intended for battery control in radio-base stations rack comprising a processing center which controls a switching system, batteries, electromagnetic locks and sensors, in order to prevent non-authorized actions of such batteries inside the racks from occurring.

Methods, systems, and apparatus for attempted entry detection are disclosed. A method for monitoring a property includes receiving, from a smart lock of a door located at a property monitored by a monitoring system, smart lock data that reflects a condition of the smart lock; receiving, from a sensor of the monitoring system, sensor data; analyzing the smart lock data and the sensor data; based on analyzing the smart lock data and the sensor data, determining that an attempted door entry is occurring; and in response to determining that an attempted door entry is occurring, performing a monitoring system action. Determining that an attempted door entry is occurring can include determining, based on the sensor data, that a person is located near the smart lock; and determining, based on analyzing the smart lock data, that the smart lock data satisfies criteria for an attempted door entry.

A door security apparatus includes a door-locking member and a sensor assembly. The door-locking member removably engages a plate. The door-locking member is a barricade that restricts movement of a door from a closed position to an open position while the door-locking member is engaged with the plate The sensor assembly is configured to detect engagement between the door-locking member and the plate.
