With the rising popularity of small boutique hotels, international travel, apartment sharing and businesses like Airbnb the rise of illicit spying via hidden cameras has also risen.
People have found cameras in light bulbs, smoke detectors, alarm clocks to name a few. There is actually a huge market for hidden cameras that are disguised as other objects.
Sometimes these can be used for good, like trying to catch a cheating spouse or a delinquent child, but using them to spy on visitors without their knowledge is both unacceptable and also a real problem that’s been in the news.
Hidden cameras are on high demand nowadays. Sometimes these are being used ethically, and sometimes unethically.
These are used while spying on various people. Some of the places where hidden cameras are used while spying are as follow.

Popular Places for Hidden Cameras
Hotels – Sometimes people are spied upon in a hotel. Now this has two usages: firstly, a hidden camera is used to keep people under surveillance, that way if someone wants to steal anything from the hotel or do any other unethical work like harassing others or attempting to murder someone, he or she will be caught in the camera at once.
All of this will allow the legal police to easily trace the criminal and catch the person.
On the other hand, hidden camera can also be used in a negative way. If someone wants to unethically spy on others, they can hide camera in the room or any other location to track the activity of the person.
Apartments – Hidden camera is used in apartment to track any person who is trespassing into the apartment. Also, if someone steals anything from the apartment, or any other mishap occurs, these hidden cams can identify the people at once.
Catch cheating spouse – This is one of the most important use of hidden camera. Sometimes, a spouse can attach the hidden camera onto the bag or other place of their partner’s accommodation.
That way they can detect whether their spouses are cheating or not. The recording on the hidden cam stands as a proof for establishing the case in the court.
Nanny Monitoring – Trusting a stranger to take care of your kids is a tough thing for many people, especially in a world today where there are all kinds of weird people and we hardly even know our neighbors.
Having a hidden camera to monitor your nanny is a perfectly reasonable excuse.
How to detect a wireless camera signal in 5 Steps
Now if you want to stay aware of hidden cameras, it’s important to detect the wireless camera signal. This can help you stay safe in numerous conditions.
For instance, one of the unethical use of a hidden camera is in the dressing room of the mall. Or it may so happen that there’s a hidden camera inside wash room. These sure intrude into your privacy and can lead to dangerous predicament.
That’s why it’s important to detect wireless camera signal. Here’s how you can do that:
1. Scan wireless networks for networked cameras – A camera can be remotely installed and operated through network. That’s why be aware of the wireless networks. Especially, stay cautious from connecting to a random Wi Fi because a camera can operate through this. It will capture your phone or other device’s camera and start surveillance.
2. Turn off lights to detect LEDs – Once you check into a hotel room or a public washroom, don’t start your activities at that instant. Take some time to get acquainted with the place. Then turn off all the lights. Then you may notice a blink of red or green light in the room.
The red/green “on” light may come from the TV or AC so make sure to turn those switches too. Even after that if you notice any blink of light, know that a camera is hidden in the room.
3. Check anything plugged into a socket for power – Sometimes cameras are designed in a way of a charger. These chargers are plugged into the socket. Often people mistake these to be a charger provided by the hotel management. But let us get this straight.
You should always carry your phone, camera, laptop, or any other electronic gadget charger as hotel authority doesn’t provide these. So if you detect any such device in the room, be sure that this may be a hidden cam.

Sometimes, this can also assume the shape of a TV wire. This is a genuine problem because hotel rooms are equipped with such TV wires. So take some time to plug these wires into the socket and check whether these turn the TV on. If the other end of the wire is not connected to a TV (which may be a hidden camera), learn that the charger actually is a hidden cam.
4. Get a radio frequency through RF detector – A camera can operate through radio frequency medium and detecting these with bare eyes can be difficult or even impossible. That’s why invest on a quality RF detector that can identify such a camera and warn you.
5. Check mirrors whether it’s a regular one or two-way – Mirror is a potential place to hide camera. Check with your finger tip. Simply touch your finger tip on the mirror to learn if it is a regular one or two way. If you find anything unusual, don’t delay to instantly contact the hotel management and change room. Also, you should ideally change the hotel if anything unusual occurs.
Other than adopting these means, you may purchase the following products. Here are some best selling multi function bug detector device.
Sometimes even the most thorough manual search won’t find all hidden cameras. Sometimes your house or property is so large doing a manual search of the whole thing just isn’t possible.
That’s where hidden camera detector gadgets come in handy.
