Abstract: A building intruder defensive system includes a shield module including a tank configured to hold pressurized fluid, a nozzle, and a zone valve connected to the tank and the nozzle, the zone valve being configured to regulate flow of the pressurized fluid from the tank to the nozzle, a sensing device configured to sense presence of an intruder, and to output a signal indicating the presence of the intruder, and a processor programmed to receive the signal from the sensing device as indicating the presence of the intruder, to control the zone valve to cause the zone to open and close so as to spray the pressurized fluid through the nozzle, and to communicate with at least one remote device to deliver system information to at least one of law enforcement and a building occupant.

Abstract: A composition for deterring intruders includes propionic acid, ammonia and water. A content of water in the composition is at least approximately 60% by weight. A system for spraying a composition comprises a nozzle configured to spray the composition in an area inside a building. The composition comprises propionic acid, ammonia and water. A content of water in the composition is at least approximately 60% by weight.

Abstract: A distracting module system includes a hydro pneumatic solution tank, a valve, a nozzle, a controller and a detecting system. The controller is programmed to receive a sensor alert signal from the detecting system and send an activation signal to the valve to regulate and control fluid movement from the hydro pneumatic solution tank through the valve and to the nozzle, and to deliver information related to the sensor alert signal and the activation signal to third party devices.
