Anyone who owns a business where assets are stored outside knows that security is very important. I have found the best deterrent for keeping my yard theft-free is Electric Guard Dog. The fence looks intimidating and the 7000-volt shock it gives to would-be thieves is unlike any other deterrent available. The system is much more effective than cameras or motion detectors, and far more convenient than dealing with attack dogs. I would recommend Electric Guard Dog to anyone who wants to stop theft issues at the perimeter.
