Abstract
The present invention includes a method and apparatus for recording data. According to the present invention, the method and apparatus includes the implementation of a “circular” buffer whereby data is capable of being recorded in a circular fashion. By implementing a circular buffer, large amounts of data can be recorded over long periods of time without the use of cumbersome video tapes and the like. An aspect of the present invention includes an apparatus for recording data. The apparatus includes an input sensor for receiving data, a buffer coupled to the input sensor wherein the buffer includes a plurality of storage portions, a central processing unit coupled to the buffer and the input sensor wherein the central processing unit stores the data in the plurality of storage portions in a circular fashion and an interface coupled to the buffer for allowing a remote data accessing device to access a specific portion of the data stored in the buffer.
