Car alarm sensor series

Tilt / Shock / Micrwoave / ultrasonic / glass break sensors

 

Microwave SENSOR ( so called "radar/proximity sensor")

By-it-now $15 Microwave sensor

 

1 .The Microwave Sensor uses radar technology to detect the disturbance of,

or mass movement in its field of operation. Detection produces a contact closure.

This technology is resistant to false detentions caused environmental condition.

 

 

2. Its small size allows the Microwave Sensor to be mounted almost anywhere.

In addition,microwave technology does not require line of sight like most infrared

units. This allows the Microwave Sensor be hidden behind plastic,wood, fiberglass,

cloth, glass, etc

and not effect the aesthetics of your installation.

3 .Designed to provide intrusion detection for soft-top and convertible

vehicles

Microwave fields are not effected by movement of air or heat, so allowing

ventilation** through the vehicle will not cause false alarms

Microwave sensors can also be used to enhance the protect to tin-top

vehicles,  expensive car stereo equipment and seat covers are the usual

targets for thieves.

 

The sensor establishes a self contained perimeter, which when broken will transmit

a trigger signal to any connected any car alarm system.with negative trigger

Wiring

RED : +12V or alarm's postive armed output

Black: connect to ground

Blue : connect to instant trigger Aux-input of alarm

 

 

 

Glass break sensor

 

glass break ( bluit in sensitive microphone )

 

1 . the sensor is not triggered by external noise, signals or vibrations.

First, the sensor  detects the vibrations of the glass and listens

for the right frequency for breaking glass. It sends trigger signal to the main

brain of the car alarm when the glass is broken or hit by a hammer.

 

 

2. Glass Break Censors use two common types of detection, vibration and

acoustic. The sensors are very simplistic and easy to understand. 

 

3 .Acoustic detectors work by hearing the noise of breaking glass. 

You may be thinking does the sensor pick up other sounds as well?

The answer is no, acoustic sensors only are tuned to pick up

the sound of breaking glass. The main advantage of these sensors is

the ability to protect  your car by using only one detector

a trigger signal to any connected any car alarm system.with negative trigger

Wiring

RED : +12V or alarm's postive armed output

Black: connect to ground

Blue : connect to instant trigger Aux-input of alarm

Ultrasonic sensor

  Ultrasonic sensors are designed to provide intrusion detection of vehicles fitted with sliding windows (as apposed to wind-up) and utilities fitted with canopies.
  The ultrasonic principle works approximately the same as police radar.
  A transmitter produces ultra high frequency sound waves, which bounce off all surfaces inside the car.
  A receiver then picks up the reflected sound waves and sends a trigger signal to the connected alarm when a change in the shape of the echo is detected.
 

Ultrasonic sensors require a rigid, stable perimeter with no air movement, i.e. convertibles will not reflect sound waves and soft-top roof's will move when battered by wind.
