Why Anti-CloakTM (anti-camouflage, anti-masking) technology is a must?
A: In the growing number of burglary cases, those related detectors were found to have no detectable effect. This phenomenon of detector failure occurs when the passive infrared channel of the detector is not sensitive enough, or it is related to the "not easy to detect" thief. Sensitivity is not enough: This phenomenon occurs when the ambient temperature is close to the human body temperature, so that the detector cannot go to the environment and the human body's infrared difference. It is related to the "not easy to detect" burglars: "The thief is not easy to detect" refers to the use of camouflage techniques, such as: an umbrella, a large cloak, canvas sheets or any means to hinder the infrared divergence. Both of the above conditions can hinder the intruder's infrared divergence and prevent it from being transmitted to the detector. In both of the above cases, the passive infrared channel becomes vulnerable and does not achieve sufficient signal strength to trigger an alarm signal. ACTTM (anti-camouflage, anti-masking) technology has overcome these two cases.
What is the role of ACTTM-Anti-CloakTM (anti-camouflage, anti-masking) technology?
A: The 810 series of four intrusion detectors is the most significant feature is the use of ACTTM-Anti-CloakTM (anti-camouflage, anti-masking) technology, this unique technology is Israel's RISCO's 810 series of microwave infrared detector patents technology. ACTTM (anti-camouflage, anti-masking) technology allows the anti-theft alarm system to avoid the situation where the entire system is bypassed due to any of the above-mentioned reasons. When the detector perceives and recognizes the presence of an intruder trying to hinder the divergence of the infrared ray, in order to ensure detection performance in this case, the detector is converted into detection by a signal channel-microwave detection technology and an alarm is triggered. When the ambient temperature is close to the human body temperature, the ACTTM (anti-camouflage, anti-masking) technology is also converted to a signal channel-microwave detection technology to detect and trigger an alarm.
In the stealth attempt, how does ACTTM identify the situation and decide to switch to MW mode only?
A: The ACTTM can distinguish IR signals from moving intruders with cloaks or umbrellas or common background and/or temperature interference signals that can cause false alarms.
Mobile stealth intruders emit very weak IR signals with characteristic shapes and frequencies. ACTTM uses a unique pattern recognition algorithm in the microprocessor that ignores signal strength and focuses on the shape and frequency of the signal. When the pattern of the signal is checked against the intruder and there is also MW detection - ACTTM switches to MW triggered alarm for a predetermined window time.
Such a weak IR signal is usually not analyzed and is therefore ignored in traditional dual-detection technology detectors.
Will 810 Series products with ACTTM generate more false positives due to switching to microwave-only mode?
A: No, the ability to avoid false positives will not be compromised. The analysis basis for the detector to send an alarm decision is based on digital signal processing. There is a strong correlation between the optical design and the software algorithms of the microprocessor, which can increase the sensitivity without affecting the ability to avoid false alarms. As long as it is uncertain whether to consider the signal as an alarm, the detector will start the verification process. If the verification process confirms that the signal continues to be like an intruder's signal, an alarm decision is supported. Hot air drift, such as from an electric heater or blower, or radio signal disturbances all have characteristic shapes and frequencies that can be identified and filtered out. In addition, the microwave sensitivity is reduced in the microwave only mode.
Is the 810 Series a "digital" detector?
A: Yes, but now the numbers are not enough. By using the same algorithms (such as some ASICs) or software algorithms based on some poor microcontrollers, you can do analog detectors in a digital way. The 810 series includes a powerful microcontroller with advanced digital signal processing. This enables the 810 Series' innovative pattern recognition algorithms and outstanding performance.
