Hacking can modify the functions of a wireless camera to display computer-screen content on an external viewing device. Such modifications, while simple, will void the manufacturer’s warranty and often require additional equipment, such as a wireless receiver and patch cables. Some camera-related hacks, like breaking into a transit system’s closed-circuit TV network or spying on a neighbor’s activity, aren’t necessarily legal or advisable. Minor modifications to your wireless camera’s printed circuit board allow you to use the camera to transfer onscreen computer content without use of a high-definition multimedia interface or video graphics array cables. Older TVs often lack these inputs and rely on RCA patch cables for audio and visual connections, which limit their use as an external viewing device. These hacks are best suited for media applications, such as viewing video games or streaming movies on a bigger screen. Hacking your wireless camera to serve as a CCTV security camera doesn’t requires physical modifications, but instead relies on software that allows your camera to begin recording when it detects activity. Programs such as Yawcam, Active WebCam and Ugolog employ your existing wireless camera hardware to distribute captured data over an LAN or, if using a wireless IP camera, over the Internet, so you can log in remotely and view its activity. Other software functions include a “growl” function, an informal term describing the option to send you an email or text message when activity on-camera is detected.
