As Peter said, not easily. 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.
