Spy camera keys are like all car keys, except that they have a miniature camera allowing you to make video recordings without being noticed. The quality of the images it provides is of very good quality. Indeed, these small spy gadgets allow you to take photos in High Definition, and this, with a resolution of 5 mega pixels. As for the videos, they are all in color and have a very sharp sound, especially thanks to the microphone of the device. The spy camera keys are also equipped with a ” motion detector” function, and the latter is automatically triggered at the slightest stealth movement it captures. These camera keys have many models leaving you a wide choice, but each of them may go unnoticed. And to make them work, you will only have to press a very discreet button for it to work.
