Tweetycam uses FHSS technology. This means that our product is a wireless device that works without WiFi or that does not rely on WiFi to transmit signals. Our FHSS monitor subdivides the 2.4GHz frequency band into sub-frequencies from which a signal is transmitted from the camera to the monitor. Tweetycam's secure system was designed so that hackers are unable to intercept the communication between the cameras and the monitor. FHSS technology works by quickly changing the channel the camera and receiver are using to communicate. Doing so randomly makes it difficult for anyone to casually encounter Tweetycam's signal and listen in or watch.
