Passive Alarm System

Did you know, a burglary occurs somewhere in the United States every 15.4 seconds? (FBI) Do you have an effective security system in place to avoid becoming the next victim of a burglary crime? In order to make sure your security system is fully functional and shall not fail you in the event of an intrusion, you can choose from a variety of sensors that best suit your needs.

Passive alarm systems use passive detectors and sensors in order to indicate unusual movements. These sensors are designed to read energy changes that occur within range.  They typically work by detecting heat emitted by living beings and can be programmed to pick specific heat signatures.

Types of Passive Motion Sensors

If you’re planning to go for passive detectors as part of your security system, here are some of the popular options that you have.

  1. Wireless Passive Motion Sensors - As compared to standard passive motion sensors, wireless passive motion sensors enable you to avoid the hassle associated with installation in terms of drilling holes in walls and placing wire ducts.

  2. Combination Motion Sensor - Uses both passive infrared technology and active sensing technology for enhanced motion detection.

  3. Contact Motion Sensors for Doors and Windows - Activate alarm when there is movement through a door or window while the sensor is switched on.

  4. Video Motion Sensors - Passive motion sensors that activate video cameras when movement is detected.

  5. Pet-immune Passive Motion Sensors - Programmed so that it does not detect heat signatures from living objects up to a specific body weight so that pets do not accidently activate the alarm.

Passive Motion Sensors: Do’s and Don’ts

When planning to install a home security system or expanding on an existing one, there are several factors that you should take into consideration.

  • Certain passive motion sensors are compatible only with systems or base control panels from the same manufacturer so it is recommended that you think of purchasing base units, sensors and other security system accessories that are manufactured by the same company.

  • You can install motion sensors anywhere in your house but it is recommended you install them around entry points and high-traffic areas.

  • Passive motion sensors should ideally be placed at a distance of around 10 to 15 feet from heating vents to avoid false alarms.

  • Avoid placing sensors near radiators, other heating appliances or in direct sunlight.

  • When installing motion sensors in hallways or other areas, place them such that when an intruder enters, he walks parallel to the sensing devices.

These general and positioning tips will help you protect your home while minimizing the probability of experiencing false alarms.



Q:What are the major differences between passive and active alarm systems?

A:A passive alarm system turns on automatically. When the key is taken out from ignition all the vehicle doors close and the alarm turns on. This is a passive alarm because the driver does not turn the alarm on. An active alarm needs to be activated by the driver. The driver needs to press a button available on the car remote to turn on the alarm system.

Q:What are the conditions of getting a passive alarm insurance discount?

A:A passive alarm system makes your car secure from theft or break in, as the alarm automatically turns on when the key is taken out from the ignition. If you are buying insurance for your car, you can avail a discount by letting the sales representative know that your car has a passive alarm system. When insurance companies see reduced risk, they offer a discount on insurance.

Q:Can you tell me about the passive alarm system for blind?

A:It is a device which helps visually impaired or handicapped people by warning them that they have entered a potentially dangerous area, which is near to an edge of boarding platform. These potentially dangerous areas are generally found in different transit systems and railways. Infra red technology is used by the device to alert individuals of these dangerous areas.
