Early Warning and detection systems

[crossbow]

I have a radio that is nothing but real,real loud static,music,voices all mixed in hooked to a motion sensor, when it is activated, it scares the s--- out of people, even myself, if i haven't been on the back side of the property for a while and trip it.

I had a boss that had his back door rigged to a light switch that powered a tape player boom box with a tape ready for any potential intruder, it played the sound of pump shotgun chambering a round followed by a gruff voice telling the person to get the *bleep* out of their house. In the pitch black this would scare the willies out of anyone.
