1. A deterrent system adapted for use with one or more sprinkler devices, said system comprising:
- a detector configured to generate an intruder detection signal when an intruder is detected within an area to be protected from intrusion; and
a control circuit for generating a sprinkler activation signal, said sprinkler activation signal being used to control one or more water flow valves associated with the sprinkler devices, such that said control circuit causes the sprinkler devices to spray water into said area in response to said intruder detection signal; and
said control circuit further including a voltage regulator adapted to operate with an operating voltage taken from a low voltage AC supply system and a low voltage DC supply system and which voltage regulator compensates for variations in such supply system;
wherein said operating voltage is substantially below 110 volts, and said operating voltage can vary by more than a factor of two.

Abstract
A water sprinkler based deterrent system is used to deter entry into landscaped areas by undesirable intruders. The system incorporates an infrared detector combined with a control circuit that is adapted to be powered from a wide range of power supplies. In this manner, the system can be easily integrated into a variety of landscape environments, including those that may or may not include a preexisting sprinkler controls system.

8. A deterrent system adapted for use with an irrigation control system, said irrigation control system including one or more sprinkler devices situated so as to spray water into a predetermined area, and one or more sprinkler water flow control devices for permitting or restricting flow of water to the sprinkler devices from a water supply, the deterrent system comprising:
-
a detector configured to generate an intruder detection signal when an intruder is detected within a protected area to be protected from intrusion; and
a control circuit adapted to generate a sprinkler activation signal in response to receiving said intruder detection signal from said detector, said sprinkler activation signal being used to activate said sprinkler water flow control devices so that said sprinkler device spray water into said protected area;
wherein said control circuit further include a voltage regulator adapted to operate with an operating voltage taken from a low voltage AC supply system and a low voltage DC supply system, and which voltage regulator compensates for variations in such supply system;
further wherein said operating voltage can vary by more than a factor or two. - View Dependent Claims (9, 10, 11, 12, 13, 14, 20)

15. A method of deterring entrance into a protected area, the method including the steps of;
-
generating an intruder detection signal when an intruder is detected within the protected area; and
providing one or more sprinkler devices adapted to spray water within the protected area; and
providing one or more solenoid control valves configured to control flow of water to said sprinkler devices from a water supply, so that water can be sprayed by said sprinkler devices into the protected area under control of a solenoid activation signal; and
regulating a low power voltage supply system, which low power voltage supply system can include an AC operating voltage and a DC operating voltage that can vary by more than a factor of two and is substantially below 110 volts;
generating a regulated operating voltage that is substantially constant despite voltage variations in said low power voltage supply system;
providing a control circuit for generating said solenoid activation signal in response to receiving said intruder detection signal from a detector circuit, said control circuit being adapted to operate with said regulated operating voltage;
wherein said sprinkler devices can be controlled to spray water into the protected area to deter entrance by an intruder. - View Dependent Claims (16, 17, 18, 19)
