Motion detectors do work on motion. The lens in the front provides the change
in intensity as the target moves across the field. If you look closely you will
see there are ribs in the lens. As the hot spot crosses the ribs the intensity
changes. The electronics see this change and trigger.
so if a deserving cat owner should be shot because their little animal dug
up your precious flowers or dirtied your shoe a little, what should we do to
say a car theif? burn them at the stake?
get a grip man. be smarter than the cat.
Cats are now being seen as the single most damaging "exotic" animal to the
environment. They will kill everything that they can catch and that usually
means you will be overrun with rats after a while. With all the birds, rabbits,
squirrels and such dead the only animal left to eat the available food is a rat
and they can reproduce faster than cats can eat them if they have the food..
If you live in a neighborhood with a bunch of stray cats and all of the
wildlife is gone you do think it is serious.
Folks in the environmental community are very concerned when you change the
balance that much. It has bleeding heart liberals out trapping cats. They do
take them to animal "shelters" instead of simply killing them but the result is
People have as much business sending their cat out to kill as someone would
turning loose a python or a pit bull.
I hate irresponsible pet owners who do not control their pets or fix
them. I live next to wilderness provincial park. Stray cat? Koyotes
will take care of them in couple of days. Also you can devise a
sprinkler which will squirt water when motion is detected.
My problem is wild bunnies eating my flowers. Had to erect chicken wire
fence around garden and flower beds.
Absolutely true, but people brought the Brazillian peppers, Kudzu and Nile
Monitors here too. That doesn't mean we don't need to control them by removing
the exotic species.
(they won't let us remove the offending people)
