Abstract: Systems and methods for linking neighborhood cameras and recording video from cameras that monitor public areas proximate neighborhood homes are provided. Some methods can include providing a plurality of cameras, each of the plurality of cameras linked to a respective security system in a plurality of security systems, each of the plurality of security systems protecting a respective building in a plurality of buildings, detecting an alarm event in a first security system of the plurality of security systems, and responsive to detecting the alarm event in the first security system, instructing the plurality of cameras to record video of a public area proximate the respective building in the plurality of buildings protected by the respective security system in the plurality of security systems linked to each respective camera in the plurality of cameras.

Abstract: A modular water leakage detector includes a housing that carries a plurality of water leakage sensors, an electrical water shutoff valve, and circuitry coupled thereto. In response to sensing water leakage, the circuitry actuates the valve to shut off a water supply. Detectors can communicate alarm indicating signals directly with one another. The detectors can include a wireless transmitter and communicate with a displaced alarm monitoring system.
