This document provides instructions for making a hidden camera detector using simple household items. It works by shining a flashlight through a tube constructed from a toilet paper roll and cut pieces of red vinyl. Any hidden camera lenses in the area will reflect the light and appear as bright red flares when looking through the detector. Surveillance cameras have grown greatly in recent years, with estimates of over 25 million CCTV cameras worldwide installed in many public spaces. A homemade detector can help locate any hidden cameras but may not be foolproof.

2. INTRODUCTION
To use a camera detector, you simply look through the device’s lens and press
a button to start emitting flashes of red light. The light reflects off any hidden
camera’s sensor, appearing as steady flares of red.
During the last few years the number of surveillance cameras has grown out
of bounds. Cameras have been installed in many public and semi-public places
such as universities, streets, supermarkets, gas stations, parking garages, cinemas,
bars, shops, busses, train stations and even discos. About 25 million CCTV
cameras are estimated to be in operation worldwide at the time of writing . Some
countries, notably Great Britain, are trying to fully cover every corner of public
life with cameras. The Privacy International CCTV states that between 225 and
450 Million Dollars are spent on surveillance technology in Britain per year,
involving an estimated 300.000 cameras. These efforts result in a person driving
through the city of London being filmed at least once every five minutes. In the
near future cameras may even be installed in all taxis, keeping an eye on the
passengers.

4. STEP-1:- Cut two pieces of red vinyl plastic from the basket:
•Cut one piece of red vinyl plastic the same size as the flashlight lens
•.

5. •Cut the other piece of red vinyl plastic about an
inch larger than the inner core of the toilet paper
roll.

6. STEP-2:- Disassemble the flashlight lens
assembly. Attach the smaller piece of cut red vinyl
plastic to the flashlight, as shown here. Then re-
assemble.
STEP-3:- Create slits. Make 1/2" (12.7 mm) slits around
the edge of the larger piece of red vinyl plastic.
•Cut the toilet-roll in two, and make two 1" (2.5 cm) slits
in it, as illustrated Tape red vinyl plastic and put the other
half of the toilet-roll over it. Tape the two halves together.

7. •Tape red vinyl plastic and put the half of
the toilet-roll over it. Tape the two halves
together.
STEP-4: Tape this tube to the flashlight and
finished.
You may want to use a better kind of tube if you
want to use the detector more than once or keep it
in a bag/purse.

8. STEP-5:- Look through the tube. Any camera lens
will light up as the flashlight shines on it. This is
illustrated with the hidden camera in the video.

9. How to make

10. Principle
It works on the phenomena where
the light reflected from a focused
optical system is reflected along
the same path as the incident light.

11.  Hidden Camera Detector help how to detect
pin hole camera or hidden camera.
 Flash the light
 if a hidden camera is illuminated and viewed by the
detector then a strong reflection from the target camera
will reveal its position to the user.
 It may not be obvious right away why it could be of any
importance to anyone to be able to locate hidden cameras.
 Some will reason that concealed cameras are more or less
exotic and thus knowledge on how to find them is not
necessary at all.

12. Our design uses extremely simple ideas and mechanisms to achieve a complex set of
actions and is intended to imitate the actions of the operators. However, these
“HIDDEN CAMERA DETECTOR” is a great weekend project for the hands on person.
Also hidden camera detectors can be purchased online or from an electronics store, but
you can save a good amount of money and have a lot of fun making your own hidden
camera detector at home.
The mechanical parts that have been fabricated are extremely simple.
•Very easy to use.
•Even have to be on for detector to work, but you will need to see through the detector
basically in the camera's field of view.
•However, someday, if you are ever in a situation where you think someone might be
watching you, you’ll hopefully remember this article and the information will be
helpful.
