Abstract: A wirelessly-controlled jamb-mounted access control system can include an in-jamb housing, a lock body at least partially inside the housing and rotatable about a first axis between locked and unlocked positions. The first axis can extend parallel to the jamb, and the lock body can include inner and outer sidewalls that define a latch cavity configured to receive a latch tongue of a door. The wirelessly-controlled jamb-mounted access control system can further include an actuator configured to control release of the lock body from the locked position in response to a control signal.
