The whole idea behind a hidden camera is to catch someone in the act of doing something wrong without them knowing about it.
Hidden cameras work best when hidden in everyday items for home, office or business.
Some examples are a tower fan, alarm clock, wall clocks, exit sign, air purifier and many more Spy cameras are a good way to find out information when you can't be at your home office or business.
It is another set of eyes for you.

They want to know what their nanny is doing because the world is a crazy place and it gives parents some sense of comfort when they cannot be with their child.
In some cases these spy cams have saved children lives.
They are worth the small investment.
Some people use the spy cameras to see what a boyfriend, girlfriend, or spouse is doing when they are away.

In many cases they find out information that they did not know previously due to having the hidden camera.
The cameras are easy to move around the room or into different rooms.
They are adjustable and can be easily installed.
