Abstract

A system, method, and apparatus for detecting wireless video cameras includes receiving radio waves in a radio frequency band and filtering the radio waves. Then it is determined whether a signal strength of the radio waves exceeds a threshold for a period of time, indicating that a video signal is present and if a video signal is present, the detection of a wireless video signal is signaled (e.g., making noise, vibrating, illuminating, blinking).

Claims

1. A portable system for detecting wireless video cameras, the portable system comprising:

an enclosure;

a plurality of video receivers, each of the video receivers operating in a radio frequency band used for video transmission, each of the video receivers housed within the enclosure;

an antenna interfaced to each of the video receivers and housed within the enclosure, each of the antennas operatively coupled to a respective video receiver of the video receivers;

a signal strength detector connected to the outputs of the video receivers, the signal strength detector housed within the enclosure;

an indication device housed within the enclosure;

a processor housed within the enclosure, the processor operatively coupled to the output of the signal strength detector and coupled to the indication device such that, responsive to the signal strength detector determining that a signal on one of the radio frequency bands exceeds a predetermined threshold, the processor initiates operation of the indication device;

at least one sensor housed within the enclosure and operatively coupled to the processor, the at least one sensor providing fitness/health data such that the processor presents fitness/health data on a display that is operatively coupled to the processor.

2. The portable system for detecting wireless video cameras of claim 1, wherein the indication device is selected from the group comprising a visual indication device, an LED, a buzzer, a sound emitting device, a heat emitting device, and a vibration emitting device.

3. The portable system for detecting wireless video cameras of claim 1, wherein each of the video receivers comprises a band pass filter tuned to the radio frequency band.

4. The portable system for detecting wireless video cameras of claim 3, wherein the at least one sensor is selected from the group consisting of a pedometer sensor, a pressure sensor, and a heart rate sensor.

5. The portable system for detecting wireless video cameras of claim 3, wherein the radio frequency band is selected from the group consisting of a 902-928 MHz unlicensed radio frequency band, a 2.40-2.50 GHz unlicensed radio frequency band, and a 5.725-5.875 GHz unlicensed radio frequency band.

6. The portable system for detecting wireless video cameras of claim 1, wherein the enclosure is in a shape of a clip.

7. The portable system for detecting wireless video cameras of claim 1, wherein the enclosure is in a shape of bracelet on a necklace.

8. The portable system for detecting wireless video cameras of claim 7, wherein the bracelet is made of a material selected from the group consisting of silicone and fluoroelastomer.

9. The portable system for detecting wireless video cameras of claim 1, further comprising a wireless transceiver coupled to the processor.

10. The portable system for detecting wireless video cameras of claim 9, wherein, responsive to the signal strength detector determining that the output of the signal strength detector exceeds the predetermined threshold, the processor initiates a transaction to a device over the wireless transceiver.

11. The portable system for detecting wireless video cameras of claim 9, wherein, the processor periodically transmits the fitness/health data over the wireless transceiver.

12. A portable system for detecting wireless video cameras, the portable system comprising:

an enclosure;

a video receiver comprising a plurality of antenna, each antenna is coupled to a band pass filter that is tuned to a radio frequency band, the video receiver housed within the enclosure;

a signal strength detector operatively coupled to the video receiver;

an output of the signal strength detector is coupled to a processor, the output of the signal strength detector proportional to a signal strength of a signal in the radio frequency band of one of the antenna, the signal strength detector housed within the enclosure;

the processor determines if the portable system for detecting wireless video cameras is receiving a wireless video signal by the signal strength exceeding a threshold for a period of time, and responsive to detecting, the processor initiates operation to notify of the presence of the wireless video signal, the processor housed within the enclosure; and

at least one fitness/health sensor housed within the enclosure and operatively coupled to the processor, the processor receiving fitness/health data from the at least one fitness/health sensor, the processor deriving fitness/health information from the fitness/health data and the processor displaying the fitness/health information on a display that is housed within the enclosure and operatively coupled to the processor.

13. The portable system for detecting wireless video cameras of claim 12, wherein the at least one fitness/health sensor is selected from the group consisting of a pedometer sensor, a pressure sensor, and a heart rate sensor.

14. The portable system for detecting wireless video cameras of claim 13, wherein the processor initiates operation to notify of the presence of the wireless video signal using a device selected from the group comprising initiating a visual indication device, turning an LED on, buzzing, sounding, heating, and vibrating.
