There are a few steps you can take to try to detect hidden cameras in your home or workplace:
Look for small, concealed devices such as pinholes or lenses. These may be hidden in objects like smoke detectors, clocks, or other household items.
Use a flashlight or other light source to scan the room for reflective surfaces that may be hiding a camera lens.
Use a device detection app or tool. There are a number of smartphone apps and other devices that are designed to detect hidden cameras by picking up the electromagnetic field (EMF) emitted by electronic devices.
Check for wireless signals. Hidden cameras often transmit video wirelessly, so you may be able to detect them by using a device that can detect wireless signals, such as a wireless router or a portable Wi-Fi scanner.
Conduct a physical search of the area. This may involve moving or examining objects and looking for any suspicious or out-of-place items that could be hiding a camera.
It's important to note that these methods may not be foolproof, and it is possible that a well-hidden camera may still go undetected. If you are concerned about the possibility of hidden cameras in your home or workplace, it may be a good idea to consult a professional who has experience with this type of detection.
