Hidden cameras have long been used in spy films, as well as by individuals for personal gain. Some can be easily detected with a flashlight while others require specialist equipment and expertise for detection.

A 14-year-old girl used hidden cameras to record evidence that her father was abusing her, leading to successful prosecution. Unfortunately, other cases haven’t had such luck: Forbes recently reviewed a federal child exploitation case in which Amazon and eBay-sold spy cameras were accused of filming children engaging in intimate acts within bedrooms or bathrooms.

Hidden cameras are typically easy to conceal: They can be concealed within everyday household and office objects like hair ties, USB chargers or even teddy bears – some models even use electricity directly as power source to stay on 24 hours per day!

Some devices can record HD video and audio with sound quality equaling traditional cameras; others even support voice activation!

While special handheld devices exist for detecting spy cameras, Victor used his phone instead. By shining a flashlight at various objects he suspected could hide hidden cameras and using his flashlight as an illumination tool, when an object reflected back light from its lens this indicated the presence of a hidden cam. But this technique only worked when connected to Wi-Fi signals; otherwise, false alarms could occur.
