“Most security experts will tell you a well-lighted yard is one of the best security options. This is true, although outdoor lights cost a lot to operate and the electricity usage contributes to air pollution and global warming. Also, bright light creates problems for many animals. Just one or two low-wattage, shielded outdoor lights in key locations, in addition to motion-sensing fixtures, will provide adequate deterrents at a reasonable operating cost.
Other simple improvements such as strong window locks, thorny bushes under windows and secure door deadbolts help, too. For example, Master Lock has a new “Night Watch” deadbolt with a switch to block the use of all keys.
A fully monitored security system is your best option if you can afford the monthly monitoring fees. With security alarm labels on all the windows and doors, a would-be thief will have second thoughts about breaking in. If he does get in, the loud siren alarm will scare him off and alert you.
Another advantage of a monitored system is it protects you against more than just break-ins. The smoke alarms also are connected to the monitoring station. This is very helpful if a fire starts while you are away at work. If your home has flooding problems, water sensors can be installed. Many of the major monitored security system control panels are designed to be compatible with X10 dialers if you cannot afford the monitoring service. When the alarm is triggered, the dialer can call several phone numbers and alert whoever answers to the problem. You may want to program it to call a neighbor and yourself at work. ”
