There are some ethical issues surrounding covert wireless cameras. While these cameras have done wonders for law enforcement agencies, there is concern about the implications of these devices falling in the hands of normal citizens. Civil liberties groups have expressed concern about normal individuals being able to hide these little cameras anywhere they want to spy on unsuspecting people.

How do you plan to use your wireless camera? Do you want to spy on a lover or are you protecting your children? Are you trying to steal information from a competitor or are you trying to prevent a competitor from stealing information from you? These are important questions to ask yourself. Wireless cameras can be applied in a very ethical, useful way. Make sure your intentions are legal and ethical.

More on Wireless Cameras

Motion sensitive wireless cameras can be hidden in a VCR, couch, bookshelf, or entertainment stand and provide video surveillance of anything that moves in the room. More advanced models can be activated by sending it a text message from anywhere on the planet. The wireless camera can then snap a picture and send it to a picture-messaging phone or email address.

Infrared imaging on wireless cameras enables the camera to literally see in the dark. If the camera features a voice activated microphone, it can record speech when it occurs. This technology is both exciting and frightening. Again, make sure your intentions are in check before you look for such a device. You don't want to undermine a person's civil liberties to achieve your own ends.
