How to see an enemy if they breach your area.

[Prepper1]

How about an i.r strobe or light?

Seen it in action on a program about afghan.

Apparently they're only visible with i.r. goggles.

If that's right, then you can buy ir led's on ebay, rig yourself a battery pack up and provided you have ir goggles you'd know something tripped the light but they wouldn't know giving you the element of surprise.
