1. An appliance for a network based security system, comprising:

  • a. a sensor component adapted for generating a signal in response to a condition present at the sensor component;

    b. a processor for generating a digital output signal corresponding to the sensor component signal;

    c. a network interface for transmitting the digital output signal via a digital network, wherein the sensor is a video sensor and the signal comprises a video signal, the appliance further comprising;

    i. an analog-to-digital converter for converting the analog video signal to a digital signal;

    ii. a motion video buffer;

    iii. an mpeg compressor associated with the motion video compressor;

    iv. a still frame buffer;

    v. a jpeg compressor associated with the still frame buffer;

    vi. a multiplexer for combining the output of the mpeg compressor and the jpeg compressor for generating a combined output signal to the processor for distribution via the network interface over the network, wherein there is further comprising;

    a. an audio sensor component;

    b. an analog-to-digital converter for converting the analog audio signal to a digital signal;

    c. an audio compressor associated with the audio sensor component for introducing a signal to the multiplexer, whereby the multiplexer produces a combined digital signal comprising a video and an audio component for distribution via the network interface over the network.
