Abstract: A smoke detector includes detector mount that can define a cavity into which air can flow to a detector component of a detector body engaged with the detector mount. The detector mount can include a base, e.g., that defines a cavity into which air can flow and/or into which a portion of the detector body can extend, and an intermediate component that can removably engage with both the base and the detector body so the base is engaged with the detector body via the intermediate component. The intermediate component can include fins or other features to direct air flow in the cavity to one or more portions of the detector body.

Abstract: A smoke detector includes a tamper indicator that can prevent a cover from at least partially covering a battery location and/or mounting of a detector body to a detector mount if a battery is not located at the battery location of the detector body. The detector mount and/or cover can engage with the detector body by relative rotation about an engagement axis, and the tamper indicator can pivot about a pivot axis that is parallel to the engagement axis and/or move along a linear path. The tamper indicator can prevent engagement of a portion of the detector mount, such as an intermediate component between the detector body and a base of the detector mount, with the detector body. The intermediate component can at least partially cover the battery location when engaged with the detector body. The base of the detector mount can engage with the detector body via the intermediate component.

Abstract: An optical device, such as a camera or spot light, having first and second removably engagable components. Disengagement of the components exposes a battery compartment in the second component. The first component can include all optical components of the optical device, such as a camera or light. A magnetic mount can provide a secure and adjustable mounting for the optical device housing on a support.

Abstract: A location monitoring system, such as an alarm system employed at a house or other location, can include a wireless, battery-operated camera. The camera can have a low power mode in which all components other than a low power communications module are deactivated. The camera can be activated by a signal received by the low power communications module, and the camera can establish a direct communications link with, and send video image data to, a remote server. Where the camera/server direct communications link is inoperable, a link to a local controller is established, and at least a portion of the video image data sent to the controller, which can send a portion of the video image data via an alternate network.

Abstract: A doorbell including a housing and mount that can be engaged such that the housing is pivotable or otherwise movable relative to the mount for engagement with the mount and/or for activation of a doorbell switch. A latch can secure the housing to the mount so the housing is secured to the mount. A switch located in a space defined by the housing and mount can be actuated based on movement of the housing relative to the mount.

Abstract: An illuminated indicator for a doorbell can be arranged to receive light along an optical axis (e.g., that is perpendicular to a front face of the doorbell housing) and emit the light from an output portion that defines a closed loop (e.g., that extends around the optical axis) and in a direction that is parallel to the optical axis. The illuminated indicator can include a light pipe that receives light along the optical axis and reflects the light to follow a radially outward and divergent path, e.g., that is perpendicular to the optical axis. The radially outward and divergent light can be reflected to follow a path that is parallel to the optical axis for emission at an output portion of the light pipe. The light pipe can be configured to transmit a doorbell switch activation force to other parts of the doorbell to cause actuation of the switch.

Abstract: An outdoor camera integrated into an alarm system for property monitoring, configured to monitor a property. The alarm system can have a base station that communicates with all the components of the alarm system, such as an outdoor camera, which can be equipped with an imaging sensor and software capabilities to conduct analysis on data collected by the outdoor camera to determine information about a human or non-human visitor at the property. The outdoor camera provides information about detected events at the property to the base station, where the data can be used to take appropriate action at the property and communicate with either the user or a monitoring service.

Abstract: A building alarm system and automated door lock arranged to place the alarm system in an armed state when a door lock fails to engage to lock an associated door in a closed position. Activation of a single button by a user or use of specific code by a user to gain access to a building can cause the alarm system to automatically rearm and for door locks at the building to be locked after entry by the user. A first responder code can be used by first responder personnel to gain access to a building after an alarm system indicates an alarm state, e.g., that corresponds to an emergency condition.
