This invention is a gunshot detection device that provides very reliable inside and outside real-time situational awareness of gunshot events, while reducing Gunshot Detection False Positives and Negatives.

An instant reaction protection system including a combined camera-immobilizer, a laser sight, a control unit and a mounting member. The combined camera-immobilizer unit including a camera member and an immobilizer member, wherein the immobilizer member includes a housing and an electrical shock firing mechanism. The housing includes a cavity for receiving the combined camera-immobilizer unit. The camera member monitors a predetermined region to aid in detecting a threat and the immobilizer discharges at least one electric shock to immobilize the detected threat when a discharge trigger occurs. The laser sight aids the immobilizer in aiming at a detected treat and is integrated with the combined camera-immobilizer unit. The laser sight aims a beam at the detected threat. The control unit remotely controls the combined camera-immobilizer unit and the laser sight. The control unit includes a key switch and a key opening for securely activating the key switch thereby causing a discharge trigger to occur. The mounting member is attachably connected to the housing member and mounts the combined camera-immobilizer unit to a fixed structure at a position that allows the camera to patrol a predetermined region for threats and allows the immobilizer to accurately fire at a detected threat.

A safety system includes an electromagnet positioned in an area. A power controller is coupled to the electromagnet to supply power to the electromagnet in accordance with an event. A trigger mechanism configured to trigger the event when the area is traversed by a person with a weapon such that upon activation of the electromagnet a magnetic force is generated capable of attracting the weapon to make continued use difficult or impossible within the area.

Threat identification devices, systems, and methods are disclosed which identify and locate various threats and provide a variety of countermeasures to reduce the loss of life in an attack. In one implementation, a device is provided with a housing and a plurality of tubes coupled to and extending from the housing. Sensors are located within the tubes for sensing external conditions. A control unit is in electronic communication with the sensors. Upon detection of an external condition, the sensors transmit a signal to the control unit, which activates countermeasures, including rotating light sources to identify the location of the external condition as well as preferred escape routes. The control unit may also transmit signals to other devices in the environment, including video panels and speakers, to provide instructions.
