Security systems are extremely effective at deterring burglars and invaders. Generally speaking, non-government security systems are used in homes and businesses, and they are especially helpful in the following locations:

  • Interior and exterior entry points like doors and windows
  • Remotely located buildings like workshops, barns, sheds, and garages
  • Distant areas of your property that are hard to monitor on a regular basis

Security systems work by monitoring these areas and sending messages either to you or to law enforcement or both. Likewise, there are often flashing lights and loud alarms that may go off in general when an invader is suspected by the system.

The Key Components of Most Security Systems

All security systems are different, but the typical components include the following:

Signs and Stickers

Signs and stickers often accompany security systems to let anyone (including would-be burglars and invaders) know that a security system is active on your property. Stickers and decals often go on the windows or front doors of your home or building, and signs are often visibly located outside in the grass.

The Control Panel

The control panel of your security system is the epicenter. This is where you turn your security system on and off, monitor activity, and ensure that everything is in working order.


There are both wireless and wired surveillance cameras available. These are often used in remote places that are not often visited and thus, cannot be easily monitored. The feed from the cameras goes to either a security room, your smart phone or computer, or another digital screen device.


There are two main types of sensors: motion sensors and window and door sensors. Motion sensors are often placed outdoors to monitor anyone who may be walking around or lurking where they shouldn’t be. Of course, motion sensors can also be located indoors.

A window and door sensor is usually made of a two-part system. On a given window, for example, one sensor will be located at the bottom of the moving window while the other will be located on the windowsill. When the window is closed, the sensors will join together creating a secure circuit. However, if the window were to open, the circuit would break, and the control panel would be notified of a breach in security.


Alarms that are often extremely loud and obnoxious may accompany security systems. This is to notify both the invader, you, and/or law enforcement that a breach in security has occurred. However, all security systems are different, and it is often the case that alarm systems do not audibly go off when a breach in security occurs. In this case, law enforcement will hopefully able to get to the scene and apprehend the invader before they know what’s hit them.
