One would argue that there's more chemistry going on in neurons feeding to the optic center, but I'm not well versed in neuroscience to tell you where the signal stops.

Is the amount of chemistry, then, or length of signal transmission, the measure of consciousness?

What is the implication for the conscious experience of the camera?

Sure, but we're gonna limit ourselves to neurons and the degree of connectivity between them. A camera has none, QED. The more challenging comparison is between a comatose patient and one with locked-in syndrome: https://en.wikipedia.org/wiki/Locked-in_syndrome. There, we can't exactly come up with some 'an agent capable of sensing the world, and responding to changes in its environment' that an outside observer might use.
