Security system including less than lethal deterrent

1. A security system, comprising:

an enclosure;

a video system disposed in the enclosure and configured to obtain images of an intruder;

a deterrent dispensing device disposed in the enclosure and configured to dispense a deterrent substance in a selected direction; and

an actuator module disposed in the enclosure and communicatively coupled to the video system and coupled to the deterrent dispensing device, the actuator module being configured to receive a video signal from the video system and, in response thereto, control the deterrent dispensing device,

wherein the deterrent dispensing device includes multiple nozzles, and the outputting of a deterrent substance from the deterrent dispensing device in a selected direction based on a location of a moving object includes selecting a subset of the multiple nozzles.

2. The system of claim 1 further comprising a two-way audio device disposed in the enclosure and configured to warn the intruder before the deterrent substance is dispensed.

3. The system of claim 1 wherein the actuator module includes a processor configured to analyze the video signal to thereby detect motion of the intruder.

4. The system of claim 1 further comprising a passive infrared motion detector disposed in the enclosure, the actuator module being configured to control the deterrent dispensing device dependent upon an output signal of the passive infrared motion detector.

5. The system of claim 1 wherein the actuator module includes a radio frequency transmitter configured to receive the video signal from the video system and transmit the video signal to a remote location.

6. The system of claim 5 wherein the actuator module includes a radio frequency receiver configured to receive a radio frequency deterrent dispensing signal from the remote location, the deterrent dispensing signal indicating whether to dispense the deterrent substance from the deterrent dispensing device, the deterrent dispensing signal being dependent on the captured images.

7. The system of claim 6 wherein the deterrent dispensing signal from the remote location comprises a numeric code transmitted from a personal electronic device that receives the video signal.

8. The system of claim 1 , wherein the actuator module is configured to use the video signal to aim the dispensed deterrent substance in the direction of the intruder.

9. The system of claim 1 , wherein the actuator module is configured to use the video signal to aim the dispensed deterrent substance based on a location of the intruder as determined by the video system.

10. The system of claim 1 , wherein the actuator module is configured to aim the dispensed deterrent substance by use of target local information provided by camera video motion sensing.

11. The system of claim 1 , wherein the actuator module is configured to rotate the deterrent dispensing device about a vertical axis and stop the rotation at a desired position to thereby aim the dispensed deterrent substance in a direction of the intruder.

12. A method of operating a security system, comprising the steps of:

capturing sounds within a monitored area with a plurality of microphones disposed in an enclosure;

determining a location of a moving object within the monitored area based upon the captured sounds;

providing a deterrent dispensing device in the enclosure;

deciding whether to activate the deterrent dispensing device; and

outputting a deterrent substance from the deterrent dispensing device in a direction that is based on the location of the moving object as determined from the captured sounds,

wherein the deterrent dispensing device includes multiple nozzles, and the outputting of a deterrent substance from the deterrent dispensing device in a direction based on a location of a moving object includes selecting a subset of the multiple nozzles to output a deterrent substance.

13. The method of claim 12 wherein the deciding whether to activate the deterrent dispensing device is performed automatically by a processor.

14. The method of claim 12 wherein the deciding whether to activate the deterrent dispensing device is performed by a human at a location remote from the security system.

15. The method of claim 12 wherein the outputting of a deterrent substance from the deterrent dispensing device in a direction that is based on the location of the moving object includes rotating the deterrent dispensing device about a vertical axis and stopping the rotation at a desired position.

16. The method of claim 12 , including:

using a plurality of passive infrared motion sensors to provide information regarding a location of a moving object within the monitored area,

wherein the passive infrared motion sensors are located in the enclosure with the plurality of microphones, and

wherein the step of deciding whether to activate the deterrent dispensing device is based on the information from the passive infrared motion sensors.
