1. An apparatus for a vehicle security system, the apparatus comprising:
- a front view camera sensor, said front view camera sensor is configured to capture 30 frames-per-second at a minimum of high definition resolution;
a rear and side view wide angle camera sensor, said rear and side view wide angle camera sensor is configured to capture 30 frames-per-second at a minimum of high definition resolution;
at least one image signal processor coupled to said front view camera sensor and said rear and side view wide angle camera sensor for performing image signal processing functions including but not limited to auto white balance, auto gain, wide-angle lens barrel distortion reduction, lens defect compensation, and motion stabilization;
a motion adaptive spatial and temporal filtering unit that is coupled to output of said at least one image signal processor for preprocessing of video data;
at least one video compression unit according to H.264 standard that is coupled to output of said motion adaptive spatial and temporal filtering unit, said at least one video compression unit can compress 30 frames-per-second at a minimum of high definition resolution;
a microphone, audio preamplifier, audio-to-digital conversion circuit, and an audio compression unit;
a multiplexer to combine output of said audio compression unit and said at least one video compression unit;
a processor to store output of said multiplexer on a removable non-volatile semiconductor storage media in a continuous record loop in a circular buffer, said circular buffer stores multiple days of storage of surveillance data, in accordance with size of said removable non-volatile semiconductor storage media, before oldest data is overwritten by newly recorded video;
an Internet interface unit coupled to said processor, said Internet interface uses an interface including but not limited to 802.11 wireless interface, 3G data interface, or 4G data interface;
a transrating unit coupled to said removable non-volatile semiconductor storage media using said Internet interface unit for transmitting said stored surveillance data at a different bit rate in accordance with transmit channel and destination capabilities;
the apparatus is housed in a single and compact housing that is mounted on the front or back windshield of a vehicle; and
said removable non-volatile semiconductor media is configured to be unplugged and contents of said semiconductor media are viewed when plugged into a personal computer or a TV.
