Well, you could use a modern day, smartphone-style camera detection device.

You Are Being Watched

Someone is watching you. This is pretty much irrefutable in the post-Snowden era. But digital surveillance of emails and telephone records is a little less hair-raising than someone actually observing your movements via a hidden surveillance camera.


It’s unlikely that you have never been filmed out in public, either on CCTV or in the distance on a TV news report, and as a society we’ve become more accepting of closed circuit cameras, security cameras, and so on (rightly or wrongly).

But what about closer to home? What about in the office, development room, bathrooms and dressing rooms, or any number of places where you wouldn’t normally expect to find a camera watching your every move?


Without being made aware of such surveillance in advance, you could find yourself being recorded, your movements and actions tracked, judged, no doubt misinterpreted. This intrusion might be performed using professionally manufactured security cameras, or custom built ones, perhaps using a webcam with an old PC Cammster: Use Webcam as Security Camera Cammster: Use Webcam as Security Camera Read More , or a Raspberry Pi Build a Motion Capture Security System Using a Raspberry Pi Build a Motion Capture Security System Using a Raspberry Pi Of the many projects that you can build with the Raspberry Pi, one of the most interesting and permanently useful is the motion capture security system.

Smartphones Can Detect Hidden Surveillance Cameras!

While it might seem like something straight out of a James Bond movie, it is possible to use your smartphone to detect hidden cameras, as well as other 007 devices 3 James Bond Gadgets You Can Make From an Old Smartphone 3 James Bond Gadgets You Can Make From an Old Smartphone The smartphone is the most sophisticated gadget we carry with us everyday. And while we don’t have our own Q Branch working for us in a secret lab, thanks to a few intrepid DIY-ers and... Read More . In general, two common methods are used to achieve this.

The first is by using the smartphone hardware to detect electromagnetic fields Is Electromagnetic Radiation Dangerous? How To Protect Yourself? Is Electromagnetic Radiation Dangerous? How To Protect Yourself? Can cell phones cause cancer after all? The media certainly knows how to screw with facts. How does radiation emitted by electronics really affect your body? Well, calm down! It's not all that bad. Read More . With the installation of a single app, you can move your phone around the area you suspect a camera to be hidden, and if a strong field is detected, you can be sure there is a camera secreted within the wall or object.

Another way that smartphones can be used is by detecting light reflecting from a lens. While this method isn’t quite as reliable, it is still worth having such an app, if only to find small objects dropped on a carpet!

Using Android or iOS to Find a Hidden Camera

You’ll find apps for both major smartphone platforms available in the respective app stores. For iPhone, the $4.99 Hidden Camera Detector is the best option, while Android users should spend some time looking at Hidden Camera Detector. You can also check out Glint Finder for visible lens detection.

Remember that other options are available. If you have access to an infrared camera, for instance, this should detect a hidden camera, while low-cost devices using wireless networking may well appear in the list of nearby Wi-Fi devices Wireless Networking Simplified: The Terms You Should Know Wireless Networking Simplified: The Terms You Should Know Do you know the difference between an "access point" and an "ad hoc network?

If you’re particularly concerned, you might also consider a $130 piece of RF detection hardware, capable of reading the signals broadcast by traditional wireless cameras, as demonstrated here:

Use Android to Find a Hidden Surveillance Camera

Hidden Camera Detector for Android is a well-regarded app, and is free to download and install. With the app running on your device, finding the hidden camera should be straightforward, thanks to the radiation detection. This algorithm is constructed to reduce noise from other electromagnetic radiation, such as from cellphone towers, non-camera hardware, and even the Earth itself.


Ready to use when you load the app, the detector software will display a red glow when the smartphone is in the proximity of a camera. However, it will also glow when near other types of hardware, so keep an eye on the number displayed in the middle of the screen, as this will exceed 100 when a camera is detected.

For added camera detection magic, Hidden Camera Detector also features an IR mode (limited to portrait orientation) with which you can find cameras that have so far eluded you. This is done by pointing the smartphone at an area where a camera might be hidden and looking for a bright white disc. The disc indicates the presence of a hidden camera.

What to Do When You Find a Hidden Camera

It’s all very well knowing that a hidden surveillance camera is watching you, supposedly without your knowledge. But what should you do about it? Well, you could always take it to a higher authority, but in the meantime, you might wish to take action.

Note, however, that the problem with this is as soon as you do this, you may well alert the observer to your realization.

However, if you’re determined to be seen, you should employ things like masking tape or adhesive putty to cover the lens, or conduct affairs beyond the camera’s viewing angle. For cameras possibly hidden high up, in lightbulbs or smoke detectors, staying out of sight can be difficult.

Do you suspect unauthorized surveillance of your movements? Have you been filmed without your knowledge? Tell us about it in the comments below.

    Yes, I know I have hidden camera's a man is telling me everything I do and say in my own privacy that no one would know. He knows if I got to the bathroom, what I am doing in the bathroom. How I sleep. If I do anything in my sleep. Every move I make he lets me know.

    I noticed my neighbor has them in the front and back of their home. The one is aimed from his upstairs window directly over my deck! And the one in the front appears to be aimed at my porch rather then theirs. I asked the police dept. in NJ- and there's nothing I can do! If its not aimed into my house- I do not feel this is right. Its just me and my 9 yr.old daughter living here. 2 nights ago I knocked at their door and asked them nicely to tilt the camera away from my house and the lady flipped out on me.. asking why I'm paranoid! Can you imagine!
    I had to remind both of them that they are the ones with the cameras - in a very safe townhouse complex! They are refusing to move them. The cop admitted he looked through the camera and it is viewing my deck! I did contact my Association but I'm still waiting to hear from them. Please.. what can I do to block these a-holes ! Im concerned for my daughter- how do i know their not recording her?

    I live at 45 Kenilworth ave, Frankston Vic, Australia, and it seems as though there might be hidden cameras and/or microphones in the house. I can never be sure, but repeatedly people react to things which have been said or action that have occurred in their absence. It came to the point where I deliberately said things to elicit particular responses and then got those responses, where the eliciting took place in the person's absence. Most likely there are cameras and microphones in the house, seemingly accessible over 3g or 4g ie. smartphone or internet. It is unsettling and dangerous as it creates opportunities for hostility and harassment. In fact I would be surprised if they weren't aware that I am typing this in now. It is likely to be a sophisticated setup. Just how small do hidden cameras get, and can they see through surfaces with infrared? I cant tell anyone because they will think I'm crazy, as several have assumed already upon hearing of this. What solutions are there at a low cost?

      The device would be transmitting your location via RF or cellular signals. RF detectors are pretty cheap I believe, but covert phone/cellular detectors are in the range of $300 to $500 and out of budget for most people. Why do you think there's a tracking device on your car?

I asked the cable man who by coincidence was 2 doors down from me this morning if I would have this in my DVR he said no not unless I had security with them which I do not. Now the question is do I believe my boyfriend that he has no knowledge of it or why it would be here.? Or is there someone else I need to worry about or am I being paranoid?

I am under house arrest and a conditional sentence order until May 21, 2017. I am under investigation and am questionable/suspicious of legality surrounding surveillance without my prior consent or knowledge, and I am in need of a geeksquad/removal team, this is a cry for help, not pity. There is one in my showerhead and bedroom lightbulb, as well as others. 'They' (THE VOICES!) have already seen me nude, and engage in intercourse with my girlfriend. I am not a paranoid schizophrenic, yet there are people watching me, narrating my thoughts even (ffs). My Anonymous mask doesn't even provide me protection.

I can see cameras at the front door and a blinking red & green lights on a what looks like a small closed laptop tucked under the top of a desk. An the owner watch me without telling me they have cameras in their home? Why watch me if they don't trust me? Why hire me? He's a retired cop.

    A week after i moved into my house my next door neighbour started going off because i had texted someone about all the recreational gear in their backyard. They were literally reading my text messages out loud and making comments thst "now the whole neighborhood knows out business!"
    By the end of two months i had comments circulating around the neighborhood about what my kids ate how often they did or did not shower and if they brushed their teeth.
    Yesterday while at a dinner with my three chikdren there were rude comments that my youngest, who has socisl anxiety disorder, will cry at the drop of a hat on the school bus for no reason.
    Everything we do is being monitored and shared - these same neighbours are claiming they are doing it because "the kids are at risk". They even share video of my kids naked in the bath!!!!!!! Im not the one putting my kids at risk!!!
    Our movements are regularly monitored in order to assist with robbing our house. Last thursday i was at walmart shopping and the next door neighbour circled me several times as i walked into the store. When i cane home there was clear evidence someone had been in my home and my next door neighbor was standing in the driveway smirking
    the next day photos of my house were curculating on social media. Yesterday there were neighbors mad because someone reported the hack on my phone.
    it started the day we moved in and 14 months later the surveillance and robberies have not stopped. The police told me that because i have a shared wall they can film me in my house!!!!?!!!@%$#!!!!
    Thanks for the tip about the phone app. The gang stalking by these psychos needs to stop.

    I am being watched by multiple up cams by all of my neighbors and they're friends. They have it set up so that it's much like the Truman Show with Jim Carrey. But I can't find the because every time I spot one it turns off and they move it soon after. But these are located all over my boyfriends house and 7 acre ranch. Even in our bedroom. I'm still at a loss. I have no clue what to do about it but I can't even change my clothes in my bedroom anymore.

        We had a huge windstorm that moved my security camera completely around and to raise more suspicion the morning was recorded showing that anybody next to my boyfriend's truck was invisible. But only that morning... they are covering their tracks. Do you want to see? I don't know how they are able to do this. It's not a scrambler. Check out the video on you tube titled "invisible" posted by David Dillon. It shows him loading up for work. Kind of, he is invisible!

          That looks like a software issue. Digital photography often reduces bandwidth by only updating the sections of the image that are new, or where motion is detected.

          I'd suggest reinstalling the camera software and firmware. Certainly share the footage with the vendor/manufacturer first, though, they should be able to provide answers.

    I believe my Husband and his girlfriend are somehow recording me and then doing their own editing. People seem to know what I say inside my own home that I have lived in for 30years. I've started having seizures and pains in my head to which I have had to go on medication and had to make an app with an Nerosurgeon. I have no idea what to do as I'm not computer savvy. I feel as though I'm losing my mind, someone even made a fake FB account with my email address that I had delegated. And so much more! I'm losing my sight due to Glacoma and have PTSD.

    I just got filmed in my local nature reserve walking my dog by two trail-cams, used by the council no doubt. Good luck answering a call of nature or surfers getting changed in the bush. This is the end of privacy as we know it.
    My first instinct was to smash them to bits - nice response from a law-abiding, tax paying citizen. This practice should be BANNED and the area sign-posted "Cams in use" if necessary. No doubt that will lead to just a "Cams in use in this State" crap everywhere.
    I really don't know where this will end.

      It is difficult to guess what people are actually doing when the potential for spying is found, and even more difficult to collect evidence of it. Try eliciting a preplanned response that they cannot resist. Provide the stimulus in their absence and check for the response. It still isn't evidence but at least you might get a clearer picture if they take the bait.

    I would be worry that my bos is spying on me through my own smartphone. It is so easy to install an app that can use my camera without my knowladge. I own an Android device and the only security method for camera control is the permissions that the app should ask (and so many apps ask this permission even though they don't really need it). I just installed an app called "Cameraless" and I can block my camera at work automatically. I think it is very usefull and there are several apps at the market for this purpose.

      A useful tip, but I think this is a slightly different problem, that of espionage against employees with work phones.
