Many folks are still living with Great Depression economic standards.. leave
a light on all night? That's idiotic, I'm not a
Rockefeller/Carnegie/Westinghouse.

Then they buy numerous cheap "0-lux" cameras and a couple of PCs and
on-'n-on technology because the thieves just keep coming back.
Recall Tom and his after-hours visitors?
Maybe extra lighting in that run-down industrial area might not have kept
those thieves away, but it will be a significant deterrent in most
locations.

The thing is, IR is visible with common devices.. which makes it easy to
avoid, and IR cameras are fairly easily defeated.

There are some very good quality machine vision IR-sensitive video cameras
available as used surplus.. again, not retail store merchandise.

Getting the crooks to walk right up to a camera is about the only way in
which the typical home surveillance camera is going to be helpful in
identifying a face well enough to be considered actual evidence, IMO.

I've watched surveillance recordings from retail store installations where
the store lighting is nearly perfect, but because of time-lapse settings
(less than 30 FPS), actual identification of individuals' faces isn't easy.

Most video equipment will be next to useless in complete darkness, and by
providing areas with good lighting, many criminals will stay away.

Of course, you can get cameras which are sensitive in the near
IR, and use IR illumination (either lamps and filters, or IR LEDs). The
IR sensitive cameras do have some intersting side effects. Light
synthetic fabrics are almost transparent to near IR, especially in
contact with the skin.

But -- isn't having the criminals stay away the idea? :-)

Enjoy,
