Some home alarm systems come standard with pet friendly motions. So pets up to 35 pounds will not be detected.

it's always a good idea that when you get an alarm system to let your pet run around in front of the motions to make sure they aren't detected.

Even when your home alarm system isn't armed, most systems will still detect motion by displaying a small red light when it sees movement.

Vibration (Shaker) or Inertia Sensors are mounted on barriers and are used primarily to detect an attack on the structure itself. These are the most durable and resistant systems for outdoor use.

A fibre-optic cable can be used to detect intruders by measuring the difference in the amount of light sent through the fibre core. Con though is these are prone to false alarms and people are stealing the cables now for the steel.

The passive infrared detector is one of the most common detectors found in household and small business environments because it offers affordable and reliable functionality. The term passive means the detector is able to function without the need to generate and radiate its own energy.

Ultrasonic detectors transmit ultrasonic sound waves that are inaudible to humans. There must be motion of an object either towards or away from the receiver. The motion of the object must cause a change in the ultrasonic frequency to the receiver relative to the transmitting frequency. Microwave detectors are another simalr form that uses microwaves to detect energy.

Photoelectric beam systems detect the presence of an intruder by transmitting visible or infra red light beams across an area, where these beams maybe obstructed. The glass break detector may be used for internal perimeter building protection. When glass breaks it generates sound in a wide band of frequencies.
