Security system communication with a user device via electronic means, including via e-mail transmitted over the internet are provided. A security system interface receives a signal indicating an occurrence of an event, such as a fault or alarm condition, in a zone of the security system; a memory stores a user e-mail address associated with the security system and the address of a server for providing internet service, such as an ISP server; and an e-mail generator transmits to the server an e-mail message based on the event. The communication node in such a system may be integrated with the control panel of the security system. The e-mail generator can transmit the e-mail using SMTP or other TCP/IP. An attachment of the e-mail, such as a picture or an audio or video file relevant to the event or the zone may be transmitted.
