(IDS - intrusion detection system) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. IDS come in a variety of "flavors" and approach the goal of detecting suspicious traffic in different ways.

Motion Detection - the process of detecting a change in the position of an object relative to its surroundings or a change in the surroundings relative to an object. Motion detection can be achieved by either mechanical or electronic methods.

Glass Break Detection - A sensor used in electronic burglar alarms that detects if a pane of glass is shattered or broken. These sensors are commonly used near glass doors or glass store-front windows to detect if an intruder broke the glass and entered.

Door and Window Monitoring - Door and Window Sensors monitor some of the places where your home is most vulnerable to intrusion. Each window and door to your house represents a vulnerable point for potential break-ins. The security of your home begins with monitoring these entry points. Home security systems monitor all aspects of safety at home and often come with sensors for each window and door as a basic security precaution that protects your loved ones and belongings.
