Abstract:
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: a. an analog-to-digital converter for converting the analog video signal to a digital signal; b. a motion video buffer; c. an mpeg compressor associated with the motion video compressor; d. a still frame buffer; e. a jpeg compressor associated with the still frame buffer; f. a multiplexer for combining the outputs 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.
