  • Advanced technique of intruder detectors for alarm systems

    Intruder detectors decide the reliability of the alarm systems. To avoid the interference, anti-detection of fault alarm and missing alarm, multiple techniques are used in detector designing.
    1. Micro-wave sending time will be staggered when one more detectors are operated synchronously.So, maximum 4 pcs MW & PIR detectors can be installed in one room.

    2. PET immunity:
    The infrared signal detected will be stored and compared with human body signal and excluded pet movement alarm.

    3. Two infrared sensors are used to detect motion.
    The signal detected will be stored in RAM and will be calculated by logical addition,
    then the result and original signal will be compared to judge whether or not it is true alarm.

    4. Anti-detection design: When the detector is set at anti-detection mode, CPU will analyze the weak signal detected and if it found it is anti-detection,
    It will active the micro-wave sensor to detect, and logical calculate both signals to judge.

    5. Auto temperature compensation design to avoid environment temperature change.

    6. Two infrared sensors are built-in. Motion sensors detected are same polarity and RF,
    electric magnetism, static electricity interference are opposite polarity.
    So, it can anti interference.

    7.Micro consumption current designed for long life battery usage.

    With the invention of these new techniques, the task will be very appropriate and easy. Some home security systems provide free equipment along with a monthly monitoring contract, while others charge hundreds of dollars for installation as well as monitoring services. The best home security systems are flexible with or without home phone line requirements. Are these Home security systems worth gaining or simply provides warranty and lowest prices, Since it was an automated system, the lock will be automatically exists after certain period.

      Aside from what's mentioned those are not the advanced as of today. Having an alarm system will not guarantee your 100% safety. What if, the alarm system got a problem during the intrusion or during the fire? Then what is the help of having an alarm system? The most advance and latest today has an alarm system at the same time having a "home alarm automation". This is a must if you have an alarm system at home. This alarm automation will serve as your backup to your security system. Let's say your alarm system got a problem, this home alarm automation will notify you either email or text via phone. That's been the latest nowadays. You are confidently secure even when you are away from home.
