thx. that actually looks like a really good deal, except that i avoid wifi in my home. everything is hardwired.
but what i said is still true. consider outdoor lighting that is motion activated. there is not an IR source for those, because there is no IR camera. the motion sensor still operates in the IR portion of the spectrum. but it is passive. it sees the IR emitted by the surroundings, and it reacts to the movement of a heat source within its field of view. that is why the motion sensors are significantly less sensitive in the summer, because there is more latent heat in the background. they don't re-invent the motion sensors just because it's being used in conjunction with a security camera. it's still the same, and operates passively. so the woman had to be an object emitting its internal heat as IR. ghosts are allegedly cold, or to put it another way, they absorb energy from the physical world and create cold spots. the motion sensor would need to react to a negative signal. not sure if it could do that or not.
