How To Find Networked Hidden Cameras Using A Cellphone

All you have to do is search for the devices that are connected to the network. It is better to turn off other gadgets like tablets, making it easy for you to search for spy cams. Follow the below steps carefully to find the hidden cameras. 

Step 1: Take your smartphone and click on the settings app. 

Step 2: In the settings section, hit the internet and network tab.

Step 3: Switch on the Wifi. 

Step 4: Take your phone to different corners and see the list of the Wifi connections. 

Step 5: When you find strange Wifi networks, move to that place and search carefully for the hidden camera.     

How to Discover Night Vision Hidden Cameras Using a Cellphone

If you didn’t find any hidden cameras using the above procedure, then start looking for infrared lights. Several IP hidden cameras come with an infrared function for night vision. 

A few smartphones arrive with filters on the primary camera that acts as a barrier to infrared light. But it is relatively rare for front cameras to have infrared light blocking filters. To find which camera will help in your case, take an infrared TV remote. Place it close to the primary camera of your cellphone and push a button. If the phone screen pops up a light, then it can detect the hidden cameras. If it doesn’t, then repeat the same process with the front camera. (1)

After finding which camera to use, switch off the lights in the place you like to scan. Now open your cell phone’s camera and start searching for flashing or twinkling lights. The hidden cameras have different sets of lights. You can find hidden cameras with one, two, four, six, or even eight lights. In general, they are purple. But a few camera lights might be in other colors like white, red, and more.

It is not essential to be near the hidden camera. If there is a hidden camera, the cellphone screen shows light even when it is a foot away. The most common places you need to search are smoke detectors, ceiling, decorations, and other electronics. 

Other Methods to Find a Hidden Camera Using a Cellphone

Below are two different methods through which you can search for spy cameras. 

Strategy 1: While making a phone call, take a walk around the area. When you hear any buzzing sound or interference, there might be a hidden camera in the surroundings.  

Strategy 2: There are lots of hidden camera detector apps which are available for both Android and iOS devices. For Android phones, go to the play store and download the relevant app. Coming to iPhones, you can browse the hidden camera detecting apps from iTunes. Install the app with the best ratings and start searching for hidden cameras in the room. (2)


Even without any special equipment like RF detectors and more, it is still possible to find hidden or spy cameras. Use any of the above strategies to check whether your residence has a hidden camera or not.
