A standalone device, connectible to a CCTV network, includes an analog video input connector that collects input image signals corresponding to views from outside the standalone device, and digital image signal data corresponding to the collected signals are output. The device is connectible to an the internet-protocol network, and a transport control protocol packetizes the digital image signal data and controls addressing of the packetized digital image signal data. An address setting routine sets an internet-protocol address for the standalone device itself, permitting connection to the internet-protocol network. A self-initiating transmission initiating routine self-initiates a connection with the internet-protocol network in response to a triggering signal on an alarm trigger input. An E-mail message is assembled, including report information related to the triggering signal and digital image signal data, and is transmitted to an address via the internet-protocol network.
