One of the most useful and ingenious ways of using a hidden, wireless camera is to put them into sunglasses. Tom Cruise and his pair of eyeglasses in Mission Impossible have gone down in the annals of surveillance history. Spy camera glasses have the camera embedded somewhere within them, for example in the nosepiece, and capture images as the wearer of the glasses sees them.

Spy eyewear, or spy camera glasses, make it possible to carry on operations without the knowledge of others. It is not only the sunglass that can function as a hidden camera. There are very unobtrusive hidden cameras that look like a normal case for your eyeglasses. They are plug-and-play ready and very portable.

Spyglasses would naturally be wireless and hidden. The same considerations that apply to regular spy cameras, such as resolution, battery life, etc., will also apply here.

The video signals are usually sent to a recorder or transmitter that is worn by the wearer of the glasses; this latest technology would require a transmitter placed not more than 18 away from the camera. This is possible if it is worn on a belt or placed in a pocket. In case of a transmitter being connected, any equipment within the range of this transmitter can be fitted with a receiver and you can capture the full footage on to your VCR, TV, or computer. Recorders will be limited by the memory they have.

Spyglasses are the tools that drive investigative journalism, crime investigation, and espionage. The cost of spyglasses can be quite high. This, coupled with their possible useful applications, makes them more professional equipment rather than home equipment.
