Skylink Wireless Security System Complete Alarm System in Giftbox (SC-1000)

With the easy-to-install Skylink Garage Door Opener G6 Smart Button and G6V Visor Clip Remote, you can open and close your garage door from either the button inside or the remote clipped inside your car. The Smart Button replaces your traditional garage door opener wall button to receive wireless signals from the remote, allowing operation of your automatic garage door opener from the outside while keeping your property secure. Every time you press your remote transmitter, a code is generated which is recognized by the receiver that in turn performs the desired function. With most systems, there is only one assigned code. Whenever the remote is pressed, it generates the same code, making it vulnerable to code grabbers who use electronic scanners to steal the code. With rolling code technology, each time the remote is used, it generates a different code which can only be recognized by a rolling code receiver. Even if an electronic scanner picks up the code, the next code will not be the same, and the receiver will not recognize the old code. As a result, systems with rolling code technology are increasingly safe and secure.
