</div>Ok - First lets admit that with respect to security alarms etc I<br>
probably don't know what I'm babbling about.<br>
<br>
That said - video monitoring with recording provides some weak<br>
deterrence, and can provide evidence for prosecution (if you get lucky)<br>
assuming sufficient lighting.<br>
<br>
With respect to lighting, I have a friend who self-installed a video<br>
monitoring system looking for a neighbor's pitbulls which keep getting<br>
out of their pen. The attached IR illumination is _limited_ on his<br>
equipment, so you may want to look for some floodlamps either in the<br>
visible or IR.<br>
<br>
Joining the the pressure alarm with a motion monitoring system may be<br>
resistant enough to false alarms to justify a local horn or sound<br>
alarm, which would slightly increase the deterrence value of the<br>
system. Alternatively, or in addition, triggering a strobe might both<br>
have a deterrent effect and improve the odds of a good solid picture<br>
being captured.<br>
<br>
And now to get admittedly weird: I think motion (the program set) has<br>
the ability to localize moving bodies in the image. Use that ability to<br>
trigger a targeting laser and potentially scare any miscreants half to<br>
death. There are probably legal consequences however.<br>
<br>
Again, there are probably legal consequences, but years ago an auto<br>
repair outfit got tired of thieves just shooting the guard dog, and<br>
hired three or four rattlesnakes. Stopped intrusions in their tracks.<br>
Unfortunately, one of the snakes wound up hibernating in a tire instead<br>
of going in their daytime tank after the evenings guard duty. Pet<br>
snakes might make decent guard animals tho...<br>
<br>
Hope this doesn't represent too much noise on the list. YMMV of course.<br>
