According to ''Chachu Bush'', When you lodge in an hotel, how do you ensure you are protected from pinhole camera? Taking a fun or business trip may eventually make you opt to stay in a hotel room and you do not know that you may be photographed without you awareness.
When staying in a hotel room, you can check with this method to ensured you are not being secretly photographed or recorded. When you have entered the room, turn the lights off, and close the curtains, open your phone camera but do not turn the flash light on. Move around the room with your cell phone, if you find a red dot, it means there is a hidden web camera installed but if none found, then the room is free of it.
You may want to share this with your family and friends who take constants trips and invariably stay in hotel rooms. Stay safe, don't be victims of nude pictures. Ciao!
