Wireless spy cameras can be split into 2 groups the most popular type uses WiFI to send the signal to either a mobile phone or PC which also allows you to view the camera over the internet from anywhere in the world. The other type is the direct 2.4 GHz type which works by sending a video and audio signal between the camera and a receiver using the 2.4 GHz transmission frequency. The receiver can then be connected to a TV or video recording device.
