RK810 series microwave infrared anti-covering green environmental technology detector common problems
Israel Legris RISCO imported iWISE "Detective" 810 series microwave infrared anti-mask green technology detectors common problems are as follows:
Why is Anti-CloakTM (anti-camouflage, anti-masking) technology necessary?
A: In the growing number of burglary cases, those related detectors were found to be incapable of any detection. This type of detector failure can occur when the detector's passive infrared channel is not sensitive enough, or related to "not easily noticeable" burglars. Insufficient sensitivity: This phenomenon occurs when the ambient temperature is close to the human body temperature, so that it is impossible to detect the infrared difference between the environment and the human body. Related to "not easy to detect" burglars: "not easily noticeable" burglars refer to camouflage techniques such as an umbrella, a large cloak, canvas sheets or any means of obstructing infrared divergence. Both of the above conditions can prevent the intruder's infrared divergence from being transmitted to the detector. In the two cases above, the passive infrared channel became vulnerable and unable to achieve sufficient signal strength to trigger an alarm signal. ACTTM (anti-camouflage, anti-masking) technology has overcome the above two cases.
What is the role of ACTTM-Anti-CloakTM (anti-camouflage, anti-masking) technology?
A: The biggest feature of the iWISE series of microwave infrared detectors is the use of ACTTM-Anti-CloakTM (anti-camouflage, anti-masking) technology. This unique technology is the iWISE series microwave infrared detection of Israel ROKONET company. The patented technology. ACTTM (anti-camouflage, anti-masking) technology allows the burglar alarm system to avoid the entire system being bypassed for any of the reasons mentioned above. When the detector senses and identifies the presence of an intruder attempting to interfere with infrared divergence, in order to ensure detection performance, the detector is converted to be detected by a signal channel-microwave detection technique and triggers an alarm. In the case of ambient temperature close to human body temperature, ACTTM (anti-camouflage, anti-masking) technology will also be converted to a signal channel - microwave detection technology to detect and trigger an alarm.
In an invisible attempt, how does ACTTM identify the situation and decide to switch to MW only mode?
A: ACTTM is able to distinguish IR signals from mobile intruders with cloaks or umbrellas or conventional background noise and/or temperature interference signals that can cause false alarms.
Moving stealth intruders emit extremely 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 mode of the test signal matches the intruder and there is also a MW probe – ACTTM switches to the MW triggered alarm for a predetermined window time.
Such weak IR signals are usually not analyzed and are therefore ignored in traditional dual-technology detectors.
Will iWISE 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 basis for the analysis of the detector's 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 increases sensitivity without affecting the ability to avoid false positives. The detector will initiate the verification process as long as it is not sure if the signal is considered an alarm. The alarm decision is supported if the verification process confirms that the signal continues to behave like an intruder's signal. Hot air drift, such as from electric heaters or blowers, or radio signal interference has characteristic shapes and frequencies that can be identified and filtered out. Furthermore, in the microwave only mode, the microwave sensitivity is lowered.
Is iWISE a "digital" detector?
A: Yes, but today the numbers are not enough. You can digitally do analog probes by using equivalent algorithms (such as some ASICs) or software algorithms based on some poor microcontrollers. iWISE includes a powerful microcontroller with advanced digital signal processing. This enables iWISE's innovative pattern recognition algorithms and outstanding performance.
