Abstract

The present invention provides a complete, easy to use and install security and surveillance system for a personal computer, which is designed to act as a peripheral to the personal computer. The system utilizes a radio frequency device having receiving and transmitting means connected between the serial port of the personal computer and various sensors to input signals to the non-data pins of the serial port whereby software in the personal computer interprets the signals received at the non-data pins to place a call to a pager or cellular phone, or communicate with another computer, produce sound effects, and/or operate video equipment.

Claims

1. A security and surveillance system operative with a personal computer system, said security and surveillance system comprising:

a housing having a wireless radio frequency connection to a plurality of remote sensing devices and a serial cable connected to a serial port of the personal computer system, the serial port having data and non-data pins;

receiving means for receiving radio frequency signals in the housing;

means for making a further signal from the radio frequency signals received in the housing and sending the further signal only to the non-data pins in the serial port so that no data signals are sent to the data pins; and

means in the personal computer system interpreting the further signals received at the non-data pins in the serial port to operate various components of the personal computer to produce programmed responses.

2. The security and surveillance system of claim 1 wherein the plurality of remote sensing devices include radio frequency transmitting means.

3. The security and surveillance system of claim 2, further including remote control operating means for toggling the means in the personal computer system interpreting the further signals received at the non-data pins between first and second settings.

4. A radio frequency security and surveillance system operative with a personal computer system, the radio frequency security and surveillance system comprising:

a plurality of remote sensing devices having means for transmitting radio frequency signals therein;

means for receiving the transmitted radio frequency signals from the plurality of remote sensing devices and forming further signals in response thereto;

means for coupling said means for receiving the transmitted radio frequency signals to a serial port on personal computer system, the serial port having data pins and non-data pins;

means in the means for receiving the transmitted radio frequency signals to transmit the further signals only to the non-data pins; and

means in the personal computer system interpreting the further signals received at the non-data pins to operate various components of said personal computer to produce programmed responses to received further signals.

5. The radio frequency security and surveillance system of claim 4, further including remote control operating means for toggling the means in the personal computer system interpreting the further signals received at the non-data pins between first and second settings.

6. A method of controlling a security and surveillance system comprising the steps of:

receiving coded radio frequency signals sent from at least one radio frequency transmitter device;

forming further electrical signals based on the received coded radio frequency signals;

sending the further electrical signals to non-data pins in a serial port of a personal computer;

interpreting the further electrical signals received at the non-data pins; and

performing tasks in the personal computer based on the interpreted signals received at the non-data pins so as to operate various components of said personal computer to produce programmed responses to received further signals.

7. The method of claim 6, comprising the further step of sending the further electrical signals to specific non-data pins, depending on which of two preselected zones the coded radio frequency signal is received.

8. The method of claim 7, comprising the further step of remotely toggling the personal computer between different settings of tasks to perform.

9. The method of claim 8, comprising the further step of setting times in the personal computer whereby different tasks will be performed at different times.

10. The method of claim 6, comprising the further step of remotely changing the personal computer between different settings of tasks to perform.

11. The method of claim 6, comprising the further step of changing the voltage applied to the non-data pins to enable means in the personal computer to interpret what tasks to perform.

12. The method of claim 11, comprising the further step of changing the voltage on at least one non-data pin from +12V to -12V.

13. The method of claim 11, comprising the further step of changing the voltage on at least one non-data pin from -12V to +12V.

14. The method of claim 11, comprising the further step of changing the voltage on at least one non-data pin from +12V to -12V and back to +12V.

15. The method of claim 6, comprising the further step of changing the voltage applied to the non-data pins to enable means in the personal computer to interpret from which of the two separate zones the coded radio frequency signal was received.

16. The method of claim 15, comprising the further step of changing the voltage on at least one non-data pin from +12V to -12V.

17. The method of claim 15, comprising the further step of changing the voltage on at least one non-data pin from -12V to +12V.

18. The method of claim 15, comprising the further step of changing the voltage on at least one non-data pin from +12V to -12V and back to +12V.
