The dummy security system isn't really a system at all; it's merely a visual deterrent to help keep your home safe. Dummy security systems create the appearance that you have a complex security system protecting your fenced yard when you really don't. Hang security signs on your front or back fence or purchase faux security boxes to set up around your house. The appearance of a well-protected home by setting up visual deterrents on or around your fence can protect your home and family at a fraction of the cost of setting up a real security system. Of course, the downfall of the dummy security system is the lack of an actual system.
Motion sensor systems turn on bright lights in the area of human movement to bring physical activity to attention. You can point motion sensor system toward the most vulnerable parts of your fence, including entry ways and areas obstructed by visual physical objects that make detection of a breach difficult. These sensors, attached to a high-hanging light or implanted on the floor, pick up human movement and ignore animal movement and other anomalies.
Alarm zone systems use motion capturing devices to set off an alarm during a breach of your fenced yard. Due to the loud sound of the alarm, which acts as an auditory deterrent, homeowners usually select sensitive areas around the home to prevent regular alarm tripping. Set up alarm zone systems around the most susceptible areas of your fence, such as the fence entrance and walkways.
Video surveillance systems usually are activated 24 hours a day and run in tandem with other types of security systems such as alarm and motion detector systems. Regardless of the security package, video surveillance gives you constant access to what's going on in your fenced yard from the security of your home. Set up security cameras from distant points to provide a wide-angle shot that covers most of or your entire fenced yard.
Take steps to improve the security of your fenced yard yourself. Place a lock on the front gate at night to prevent easy entry into your yard. Clean your backyard of any large children's toys or other items that provide the perfect hiding places for potential criminals. A clear and open yard offers little cover and acts as a deterrent. Fenced yards are the setting for a dog that can serve as a visual deterrent and warning system for your home. The fence keeps your dog within the confines of the property.
