An exemplary bolt assembly includes a housing, a bolt, and a magnetic sensor. The housing includes a tubular sleeve configured for mounting in a latch bore of a door. The bolt is movably mounted to the housing for movement between an extended position and a retracted position. The magnetic sensor includes wires that extend through the tubular sleeve, and is operable to transmit information relating to an open/closed position of the door.

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.

An electronic door lock includes a dead bolt moved by a deadbolt transmitting assembly, a spring-loaded latch bolt moved by a latchbolt transmitting assembly, a lock core rotated by a core transmitting assembly, and a spring-loaded prying resisting member. A monitoring unit includes sensors respectively corresponsive to those assemblies and the prying resisting member, and a security controller which performs a security procedure in accordance with position of those assemblies and the prying resisting member sensed by the sensors.
