Is This An Applicable Idea for Security?

Instead of foot or vehicular patrols or dogs, maybe this is a good way to protect Shiloh and other communities:-

That big booming voice Martin County beachgoers might hear next year along the sandy shores will not be coming from the heavens. It may be Martin County officials trying to scare off people looking for sex on the beach. The county is exploring the idea of installing "talking" cameras at several of the public beaches to ward off or catch people engaged in public sex.

"I'm all for it," said Commission Chairman Michael DiTerlizzi, who first proposed putting Web cams at beaches after several recent arrests of men soliciting men for sex at county beaches. "Anything that deters that kind of activity is going to be good."

FlashCAM devices sense motion and then flash a bright light, said David Graham, assistant to County Administrator Duncan Ballantyne.

After being activated, the cameras issue a pre-recorded verbal warning to let people know they are under surveillance, Graham said. Sixty seconds later, they start recording. The cameras, which the California company of Q-Star Technology makes, are solar powered and can be connected to light poles or even trees along the shores, Graham said.

Or maybe this heat gun:-

The heatwave weapon can, by contrast, target troublemakers from 750 metres. It works by dispatching high-powered radio waves from a vehicle antenna, similar to a satellite television dish, causing the molecules in a target's skin to vibrate violently, creating a burning sensation.
