Ill-wishers can monitor people not only through the victims' personal devices, but also through hidden cameras.
Kaspersky ICS CERT expert Vladimir Dashchenko spoke about simple methods that will help to recognize surveillance through cameras.
The search for hidden cameras is probably best left to a professional with specialized equipment, the RIA Novosti article emphasizes.
You can also buy optical detectors or electromagnetic radiation detectors.
Dashchenko reminded that the device should be directed towards places where a hidden camera may be located.
He also said that surveillance can be detected using a smartphone. If you turn on the flashlight and camera at the same time, you can see glare on the smartphone screen.
The smartphone will help to detect infrared radiation that cameras use to shoot in the dark.
The expert noted that the front camera should be used to search for hidden devices.
In addition, he advises checking through the router which devices can connect to the smartphone via Bluetooth.
