IQ-180 is a super-sensitive version of IQ-140. So sensitive in-fact we keep it reserved for very special projects where the customer needs to detect very tiny objects in very low contrast areas. We find that IQ-140 is sufficient for 99.9% of our customers.

Technically, IQ-180 can detect objects that are 4×4 pixels in size and it is capable of detecting objects that may be invisible to the human eye. An example would be a black bag on a black floor, hidden by a shadow. Even if the naked eye can not see the object due to the low contrast, the IQ-180 may still be able to detect it.
