A security method and apparatus is disclosed. In one embodiment, a method for providing an alarm for a window by a security apparatus comprises calculating a first distance between a detector mounted within a movable portion of the window and a window frame edge and calculating a second distance between the detector and the window frame edge. The method further comprises determining whether the movable portion of the window has remained stationary for more than a predetermined time period based on the first distance and the second distance and, if the movable portion has remained stationary for more than the predetermined time period, storing the second distance in a memory, placing the security apparatus into an active alarm state, calculating a third distance observed by the detector, determining a change between the third distance and the second distance, determining whether the change exceeds a predetermined distance, and generating an alarm signal if the change exceeds the predetermined distance.

The present invention relates to a system for testing the availability of a detector for detecting smoke. More specifically, the present invention relates to a detector with a testing unit arranged to detect whether the detector has been covered, such that it is unable to perform its function as a smoke detector.

A method of calibrating an optical detector includes positioning a calibration block relative to the optical detector and determining a first calibration point of the detector using the calibration block.

Systems and methods are provided for enhanced alert generation based on real-time manipulation of datasets. An example method includes accessing datasets including a plurality of rows each indicating a plurality of values. Occurrences of alert definitions are monitored via applying the alert definitions to the datasets, the alert definitions specifying expressions utilizing one or more of the values, with an occurrence of an alert definition indicating satisfaction of the specified expression and causing an associated alert to be generated for evaluation. Presentation of an interactive user interface associated with customizing alert definitions is caused. The interactive user interface presents a first visual portion, the first visual portion enabling specification of an expression for a customized alert definition. The interactive user interface presents a second visual portion, the second visual portion comparing occurrences of an existing alert definition with occurrences of a customized alert definition specified in the first visual portion.

A method of calibrating an optical detector includes affixing a calibration material to a first surface of the optical detector and calibrating one or more parameters of the optical detector using the calibration material.

Embodiments relate to a device for mounting on a wall for monitoring an environment. In one embodiment the device comprises: a body comprising: an active reflected wave detector; and a processor coupled to the active reflected wave detector, the processor configured to: control the active reflected wave detector to measure wave reflections from the environment to accrue measured wave reflection data, and identify a status of a person in the environment based on the measured wave reflection data, wherein the processor assumes, for said identification, that the active reflected wave detector is at an operating height above a floor of the environment. The device comprises a cord extending from the body, the cord having a length for ending at the floor when the device is mounted with the active reflected wave detector at said operating height and the cord is freely hanging and straight.
