If you’re the paranoid type, you may have already installed a nanny-cam in your home to keep an eye on the sitter. But, did you ever think about who might be watching you?

The Spyfinder hidden camera detector finds any wired or wireless camera, active or not. Using LED technology and advanced principles of light refraction, this little wonder will keep prying eyes off of you. [Editorial note: I’m somehow feeling the urge to reference that oh-so-appropriate Daryl Hall and John Oates song here, but I won’t!]

Available at many spy shops, this unit is comparatively a great value at about $100. Most ‘professional’ models go for at least five times that. Makes a perfect gift for your favorite babysitter who talks on the phone too long or has her boyfriend over when she shouldn't.
