Home Security Systems

How does a security system work?

Home security systems work by securing entry points into a home with sensors that communicate with a control panel installed somewhere in the home.

The sensors are normally placed on exterior doors and easily accessible windows. Open spaces within the home can be secured by motion detectors.

Smoke & Fire Detection senors can also be connected up to a security system and placed throughout the home. In Louisiana, all single and two family dwellings constructed after January 1, 1992, shall contain approved smoke detectors. When connected to a security system, these senors are always active and being monitored whether your system is armed or not.

Control Panel: The control panel is the brain of your system. It is a computer that arms and disarms your system, communicates with all of your devices, sounds the alarm when ever a device is triggered, and sends all signals to our monitoring station.


Door and Window Sensors: Door and window sensors are made of two parts that are installed next to each other. One is installed on or in the door or window and the other is installed on or in the door or window frame.

When the security system is armed, these sensors communicate with it by reporting that the point of entry is secure. Should a monitored door or window suddenly be opened, the security circuit is broken and the control panel interprets this as a breach of a secured zone. A siren is sounded and in most instances our monitoring station is automatically notified.

Motion Sensors: Motion sensors are normally installed in open spaces. They detect intruders by creating an invisible infrared zone that cannot be breached without sounding an alarm. These are usually used to protect rooms containing valuable items or less frequented larger rooms.

Keep in mind that motion sensors aren’t error-proof, and there are instances in which there could be false alarms. False alarms are usually caused by electrical failures, user error, poor application engineering, power surges, lightning, and faulty equipment. If you have pets, make sure your motion sensors are pet immune.

Smoke & Fire Detection Sensors: One of the great things about today’s home security systems is their ability to detect more than just break-ins. Depending on the equipment you connect to your control panel, you can also monitor environmental threats, including fire, carbon monoxide, and smoke.

Even though a security system can only alert you to an issue—and not prevent or solve it—detecting such problems early on can help you fix the problem before it causes extensive damage.

If the system detects carbon monoxide or smoke from a fire, it will automatically contact the monitoring station to alert the authorities. This is a great feature so you can feel more at ease when you’re away knowing your home is being monitored 24/7.

Sirens: Home security sirens serve a few different purposes. First, they alert the people inside the house that a problem occurred. Second, they are also loud enough to send a burglar running while also notifying nearby neighbors to the situation.


Yard Signs & Stickers: On the surface, these items might seem like nothing more than marketing tools for alarm companies, but they play important roles in home security. When you place a Simpson Security sticker in a front window and plant our sign in your front yard, you are telling burglars that your home is professionally protected and not a wise choice for an attempted burglary. They are effective at conveying this message and we highly recommend placing them around your home.
