If this is an IP camera, you could connect to the camera and read the stream. Depending on the format of the stream (i.e is it H.264?), you may have to decode it. Then using the gd functions, isolate the area containing the light and determine the brightness of the pixels. Repeat for multiple frames and compare the results. As I said - not easy. It would be much easier to hook into whatever is triggering the flashing light and sense that. -- ================== Remove the "x" from my email address Jerry Stuckle JDS Computer Training Corp. jstucklex@attglobal.net ==================
