The present invention is directed to a method and system for installing and programming a network interface module within a security system. A security programming system may be implemented from a computing device connected over a network with the network interface module. The computing device may communicate with a server storing components of the security programming system. The security programming system may include user interface components located on the server and accessible through a browser of the computing device to enable selection of a network interface module participating in the security system and selection of a security system application program. The system may additionally include one or more programming applications located on the server for programming the selected network interface module to operate within the security system, wherein the programming application is selectable from the user browser of the computing device.
