1. A video surveillance system comprising:
- at least two video cameras each configured to independently generate video data; and
a video controller coupled with the video cameras, wherein the video controller is configured to substantially synchronize and then merge the video data generated by each of the video cameras to form a single contiguous stream of common video data, the single contiguous stream of common video data storable in a data file.

Abstract
A solid-state video surveillance system includes at least two video cameras and a video controller unit. The video controller unit synchronizes the operation of the video cameras such that video data may be independently generated from each of the cameras substantially in phase. The video data from each of the cameras may be merged and stored in a data file. The data file is a continuous loop such that newly stored video data continuously overwrites the oldest previously stored video data. The data file may be stored in a detachable solid state memory device.

15. A video surveillance system, the video surveillance system comprising:
-
a first video camera configured to independently generate a first stream of video data;
a second video camera configured to independently generate a second stream of video;
a sync and frame merge module coupled with the first and second video cameras, wherein the sync and frame merge module is configured to enable generation of the second stream of video data in substantial synchronization with generation of the first stream of video data by establishment of a constant phase relationship between the first and second streams of video data, the sync and frame merge module also configured to switch between the first and second streams of video data on a frame-by-frame basis to generate a single contiguous stream of common video data;
a video processing module coupled with the sync and frame merge module , wherein the video processing module is configured to compress the single contiguous stream of common video data; and
a microcontroller coupled with the video processing module, wherein the microcontroller is configured to direct storage of the compressed single contiguous stream of common video data. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A video surveillance system comprising:
-
a first video camera configured to independently generate a first stream of video data;
a second video camera configured to independently generate a second stream of video data;
a camera clock coupled with the first video camera, the camera clock configured to provide a common clock signal to the first video camera to enable generation of the first stream of video data; and
a clock hold off circuit coupled with the second video camera and the camera clock, wherein the clock hold off circuit is configured to selectively enable the second video camera with the common clock signal to generate the second stream of video data in substantial synchronization with generation of the first stream of video data. - View Dependent Claims (24, 25, 26, 27, 28)

29. A method of capturing video data from a plurality of video cameras, the method comprising:
-
providing a first video camera capable of generation of a first stream of video data and a second video camera capable of generation of a second stream of video data;
stopping generation of the second stream of video data until a determined condition is detected in the first stream of video data;
starting generation of the second stream of video data to generate the second stream of video data substantially synchronous with the first stream of video data when the determined condition is detected;
interleaving frames from the first stream of video data with frames from the second stream of video data to form a single contiguous stream of common video data; and
storing the single contiguous stream of common video data in a continuous loop with a determined duration. - View Dependent Claims (30, 31, 32, 33, 34, 35)
