Whether you need a simple home security system or require fortress-like protection for your castle, there are many companies and features to choose from. With some research and comparison shopping, you’ll soon have the peace of mind that no one can enter your domain without you knowing about it.

Standard systems
The basic home security system allows occupants to monitor the interior and exterior areas of their home, and, should you choose, alert emergency services in case of a break-in or fire. Generally, these systems include motion sensors mounted on windows and doors. A control pad operates the system, allowing users to arm and disarm the alarm via key codes. Some systems run on batteries and some are electric, with a back-up battery.

The alarm itself can be silent or loud. You can even mount speakers on the exterior of your home to alert neighbors that an intruder is in your home or that there is some other type of emergency.

An alert on the system, signaling a possible break-in or fire, can be monitored by the alarm company, who will contact the police or fire department, usually after calling you first to make sure you are all right and that the alarm hasn’t gone off accidentally.

For those who are rarely away from home or simply prefer to do the monitoring themselves, there are alarms that will send a voice message when any part of the security system has been triggered.

Upgrades
You can optimize your system to reflect the level of security you’re comfortable with. Additional door/window sensors and motion detectors can be installed, as well as smoke detection sensors, breakage and leakage sensors and temperature change sensors. Close-circuit television (CCT) and wireless video surveillance (VSS), which connect to a DVR recorder, are other options.

Which one is right for you?
What level of security you need for your home is based on personal comfort level and the value of your household inventory. Professionals who keep a lot of electronic, musical or film/video equipment at home, for example, would want to consider extra security, but others might find family photographs and their record collection to be priceless possessions deserving Fort Knox-style protection. Ultimately, break-ins can be random events, so the best way to select your security system is to let the value of your worldly goods and your gut instinct be your guides.

Shopping around
There are many companies offering security these days, so you have a lot of choices. Some housing developments pre-install wiring intended for a specific company, so if you have a new home, be sure to check with the developers.

Compare costs, services and convenience. If you have children, pets or come and go frequently, you’ll want an alarm that is flexible and easy to use. Some systems require a dedicated phone line, which is a consideration if you use only a cell phone.

Look for special offers and coupons and feel free to negotiate before you sign the contract. Also check with your homeowner’s insurance carrier to see that your policy reflects the addition of a home security system. Most insurers give discounts for them.

Regardless of the type of security system you choose, there is no substitute for knowing there is something more than your own senses — or your neighbors’ — on the alert for intruders or other dangerous activity in your home.
