The only way I know is to detect the video transmission from the camera.

If its composite video down a coax then even this would be difficult, but then the cable might be easy to find. If its one of these with a built in transmitter at around 2.4GHz then that would be easy, only problem might be eliminating all the other transmissions around you...

if the camera has night vision capabilities, it will emit an IR light - when viewed thru a similar camera (Sony video camera with night shot) the IR light is like a spotlight.

I discovered this one night just goofing around with my video camera at an industrial site... after the overhead lights were turned off....

... I just realized what a pathetic life I lead!

I'm not sure, (I'm not that smart) but maybe the CCD's within a non night mode camera will still emit or reflect certain light waves?

how about it Gurus?

I don't know about finding the camera, but lighting a magnesium flare and waving it around will pretty much put your mind at rest, 'cause the camera will be burned out from the intensity of the flare!

If you are close to the camera and your own eyes survive!!!

Do you always carry such things around with you???

I had a bad feeling that someone might be entering my apartment, so I got a wireless CCD camera and connected its base station to my recorder. Fortunately, I was just paranoid. However, I did not have it set up for night vision. So, if a hidden camera is not set up for night vision there will be no IR spotlight.

And, yes, I do carry these things around with me. You never know when you have to make a mad dash into a cave!!!

I agree, if no IRis being emmited, you wont find it.....Quid pro quo....

I was just pointing out that any CCD camera shows IR sources as a very bright light!!! Nothing special needed......

All digital cameras (pictures and Video) will show up infra red sources as a bright light, even if Sony Nightshot (or similar) is not available. You need nothing special, try it out.

I found this out quite accidently some years ago and I use it to check infra red remote controls for correct operation.....

It would appear that most CCDs in digital camera equipment are at least as sensitive to IR as they are to normal light!!!

Use the digital display, not the viewfinder as some viewfinders work only as normal optics, at least on still cameras....video cameras generally tend to have a mini LCD display.....

Remember, old analogue Videos may not work, I have never tried it, the same with film cameras....

You have to think like the person who would install such a covert camera. What are they hoping to watch in the room and then carry out a close inspection of the area most likely to hold the camera. Check any new additions to the room such as wall clocks, dummy IR detectors, wall hung pictures and any unusual black dots in the coving/partition wall, examine the light fittings. Most modern cameras will be wireless so should be easy to pick up with a scanner, (Maplin stocks them and the cameras too so you could check it out in the shop first). If the camera is wireless I presume you want to catch the culprit to stop any repeat so make a note of any person watching your movements into rooms who carries their own laptop around with them all the time. If you do carry out a search then the voyeur will know you are suspicious and may be easy to catch when they try to remove the camera.

My experience of covert cameras is for investigative TV and they are VERY tiny devices hidden as rivets in the top of a brief case or coat buttons, etc. If it is installed by a professional you will have a hard job finding it but most 'voyeurs' will not have the equipment or knowledge to hide the camera perfectly.

Good hunting!!

Did you ever read the article about Holiday Inns, and the fact that many were designed with a hidden passage way that led between the rooms? Also, the bathroom mirrors (which could see in the bed area) were actually one-way mirrors!

One couple got suspicious when they heard some noise, so they tore the mirror out and found the passage. At the point of there mirror, there were candy bar wrappers and empty soda cans in the passage! Turned out that this Holiday Inn was not an exception!!!

Re: Finding a Hidden cams

10/21/2007 7:57 AM

To be honest Andy, All we have to go on is

Is there any device which can find the presence of a hidden cam?

This is all we have to go by! The only answer I can come up with is Thumb screws using the following method:-

1. locate your suspect who you believe to have hidden a cam to spy on you.

2. casually place their thumb in the thumb screw and apply a bit of pressure.

3. casually ask if they have hidden a cam in your vicinity.

4. casually increase the pressure until the desired answer is reached and you have found the cam.

5. If this does not reveal the whereabouts of the cam then repeat steps 1 to 5 on all suspects until a satisfactory result is offered.

6. casually remove the thumb screws.

7. casually redirect the cam so that it points at your ass and then pull a moonie while flicking the bird!

8. casually remove the battery and claim 'Oh! finders keepers!'

9. casually mince off to the bar to tell your mates about the perv with the cam!

Anyway, James Bond never took this shit! He was trained to spot hidden cams, mikes, and spying paraphernalia at 20 paces!

Re: Finding a Hidden cams

10/21/2007 9:29 AM

WONDERFUL!!, many thanks!!

But even you assume that it is in a place or building where it probably should not be.....not on a road!!!

Mince, Mince.....(Isn't that something sold in Pies at Christmas? Tesco fare?)

Seriously, if I did find a hidden camera in somewhere where it should not be, I am sure that I could think of a few games to play first to get the spy hot under the collar.....

In fact, we could probably open up a new CR4 Forum JUST for that!!!!!

Like, if its somewhere where we could hang a coat or a picture, cover it up and have wild sex party, preferably with a lady of his aquaintance.....she does not even have to be there really or speak.....find a romantic film, copy some of the steamy stuff sound wise and play it back near to the camera (assuming a mike is built in of course....!)

Place something so that the view is restricted to what you allow him (or her!) to see...and hear.

place a radio switched right next to it when yo do not want him to hear you.....mention his name and then switch the radio on!!!

Act out short plays with friends that you all have written....bringing his name into it!

Tell jokes either about him or just use his first name as the name of the person in the joke......!

At the end of the day, I would get the police and show them the camera and your other findings......I doubt if it will be radio and if yes, the range will not be much....so you probably only have to follow a cable and get fingerprints taken by the police!!!

Then have him charged.....

Gee! didn't anyone think the question might have come from someone wishing to avoid a legit camera placed so as to be unobtrusive and thus more likely to catch suspects unaware?

I like the magnesium flare, sort of a "sweeper tool" to clear an area of suspected but unknown hidden cameras. But won't that set off fire alarms and smoke detectors?

When all the authorities come running, just tell them you were looking for a hidden camera. I'm guessing they'll move away slowly and leave you alone.

The best solution (this always works eventually) is to select a few random location and take a sledge hammer and start beating holes in these locations. If you do not find a camera in the first round, then select a few more random locations, excluding the previous locations from the selection process, and repeat with the sledge hammer. You will eventually find that hidden camera and disable it. If you don't find it just continue the process until you do.

oh, thats a serious problem.

if someone spy in your important room, like office and meeting room with a tiny camera thats worst.

1 check line at first to see if thee are any more tiney wire outlet.

2 test hf electromagnetic field with a high sensitive detector to find radio from the camera.

3 in a dark condition, use a spot light source scan around and view with a mirror to find a reflect lighting spot.

last, ask antispy agency for helping.

its terrible. its challenge law.

1. Install your own cameras and connect them to the internet. Nobody will want to install their own camera to get what is already available.

2. Charge a small fee for people to install their cameras in your space, or rent the output from your own cameras for a small fee (try to get them to sign up for a whole year).

3. Live your life in such a way that nobody will be interested in you or what you do in the privacy of your own space. Then you can forget about hidden cameras altogether.

>>3. Live your life in such a way that nobody will be interested in you or what you do in the privacy of your own space. Then you can forget about hidden cameras altogether.

Unfortunately in a totalitarian state you will find that the state is always interested in what you are doing and for reasons more nefarious than the Holiday Inn employees....

Hidden cams are going to be very difficult to find unless they are using some sort of bandwidth to transmit wirelessly. If the cam is using optical fiber to run to a remote sensor then you have to find the cable itself. Depending on the location this could be all but impossible. Remember the case of the US Embassy in Moscow that was built by Soviet contractors? Turns out it was so riddled with bugs that it was easier to tear it down and start over again...

You might check out the table of contents of a book about creating such devices.

ISBN 0-07-146894-3 101 Spy gadgets for the Evill Genius, Brad Graham and Kathy McGowan.

I found mine at the local book store in electronics section. You might be able to find helpful information from the simple projects and explanations of the technology provided.

Any hidden camera is going to have a limited range as far as wireless goes ... smaller the camera shorter the range. Might be easier to find the receiver or recording device. If its your house then it should be a snap. If its your office forget about electronic sniffer ... way to much interference, best to do it the old fashion way. Lock the door then look for installed components. easiest install would be a "upgrade" on your computer and a small wireless in a plant or an air duct. Easy to justify,install and remove. And if its cabled it would be easier to find unless someone went to great lengths.

Depending on how serious a problem you have, a sensitive field strength meter that covers ~ 1MHz to 60 GHz ought to cover the majority of audio only to video/audio systems. This would include the amateur radio service, CIA, NSA, FBI, KGB (or whatever they are now) and whatever else you can imagine.

Some systems are passive and are designed to be retrieved. These can be detected because all electronic devices emit RF "noise".

Prices range from $50 to $50,000 and beyond. Need more info let me know.

Re: Finding a Hidden cams

Hi guys

So,there are no device available right now to detect the presence of Hidden cams except for the presence of mind.If one is smart enough,he can find one.If one is ignorant- some one is going to make money out of it.

Now adays we see lot of porno websites offering live transmissions from hidden cams.They make money from our ignorance.Can we allow this to happen.Now a days there are no private places as such.Invasion of privacy of someone is an offence.

This is an opportunity as well as challenge to Engineers to develope a hidden camera detector.( of course an affordable one- not for $50000)

.......Hi guys

Wrong conclusion. As I said in my response to your question, many devices exist and not all of them are expensive. It will depend on how sophisticated the device is one is trying to detect. You apparently have not done any searching via the internet. This is one of MANY sites that have such equipment: http://www.supercircuits.com/

Counter surveillance is a well developed field of engineering and science. Try doing a bit more online research. I think you'll be surprised.

What you are talking about is a "bug finder". It need not be a wireless device to be found. Just enter TSCM into a search engine and you will find plenty.

Good luck with your quest.

Straight answer. Yes

All electronics emit noise that can be detected.

If you know what frequencies you are looking for, a sensitive RF detector tuned to the frequency band will detect it.

Get one of your friends to help you fake a murder in the area of a camera ... you drag his "lifeless" body out of the room and wait for the cops ..... no cops ... no camera. Oh and make sure nothing happens to your friend in the mean time .... they make movies bout that kind of thing.

yes. cameras generate heat and the lens

be detected from the residual infrared.
