How does the TacSight thermal imager compare with night vision equipment?

Night vision and thermal imaging are two completely different technologies. Both have their place in law enforcement operations. Night vision depends upon and requires some level of residual light in the scene in which it is “looking.” That residual light is amplified so that the viewer can see an image he might not otherwise see. Camouflage, dense wooded or underbrush growth and other visually obscuring elements cannot be foiled by night vision equipment. Also, night vision equipment and the wearer can be “blinded” by an exposure of too much light. Night vision equipment is generally delicate and easily damaged. Night vision does provide tactical advantages in that it does not “paint” or “pinpoint” the user. It does not emit a light that those being pursued would see or target. TacSight thermal imager does not require any light, and does not depend on light. It does not matter how much or how little light there is in the scene. TacSight detects long wave infrared heat.
