Detection Technology - Essay Example

Efficacy of Detection Sensor Name Institution Affiliation Introduction In the present day, many of the detection technology largely depend on the scope and the objective of the system. It is for this reason that there are two main classes of detection technology, that which is sensor based as well as the vision based. The vision based type of detection technology often uses cameras that are intelligent enough to capture a wide range of items at on one occasion together with an image handling that will be able to recognize the kind of item captured. Nevertheless, the sensor-based detection applies several sensors, with one of the sensors used to detect the properties individually. Additionally, the sensors are mainly distributed into two sets, the non-intrusive and intrusive sensors. The detector functions through a varied mixture of ink. The optically variable ink contains varied pigments that indicate a large color shift as a result of the strong variations in the color relying on the angle of observation as well as the lighting. It contains multi-layered micro flakes in a transparent ink container. The dyes flakes are an atomic waveband-selecting optical medium that is a disturbance filter. Whereas the Iridescent ink comprises of transparent dyes containing a thin film left on the tiny mica flakes. It through such ink that the incident light is able to be detected since it causes its disturbance making it shiny, pearl-like sparkling effects with changes in color when the angle of observation alters (Rogalski, 2010). Through the capacitive sensor, it is able to detect the presence of the security cord since the line is made up of a substantial material different from the rest of the banknote substrate. The unique arrangement of an optically adjustable ink also can lead to a unique register on the capacitive sensor. The laminates comprise a partially cured, flexible acrylic face sheet that has a primer layer on one surface thus making it bonded to a type of layer known as binder layer since it has a layer of reflective glass beads embedded in itself. The sealer, binder, and spacer layer are all generated from the uncured polyvinyl butyral material. Type of Dual Technology Detectors Dual technology detectors refer to the application of different technologies while at the same time combining multiple sensing technologies into one detector that can assist in identification of an item (Lewellen, 2008). This it does by reducing detection probabilities as well as increasing vulnerability. For instance, numerous dual-tech detectors combine both the microwave sensor as well as PIR sensor into a single unit. In order for the detection to take place, both sensors must trip at once. It is for this reason that it reduces the possibility of a false alarm as light and heat variations may trip the PIR and not the microwave, or may prompt the microwave and not the PIR. One advantage of these dual tech sensors is that if a person try’s to fool either the microwave or PIR, the sensor will not detect anything (Gross, 2010). However, at many times the PIR technology is usually paired with another model to ensure maximum accuracy as well as decrease the energy usage since the PIR draws less energy than microwave detection. Today, there are wide range of dual technology detectors, they include the following types, Digital Dual Tech & Combined Non-Overlapping, with Anit-Mask, PIR & M/Wave Detection, Mirage Pet Immune Dual Technology Detector, Microwave with Sealed Optic Wide Angle Quad PIR Grade 2, Ceiling Mount Dual-Technology Digital Detector PIR, Digital Combined PIR and Microwave Detector, Microwave Combination Detector, Twin Technology Infrared & Microwave Detector and Dual Tec, Motion Sensor with Mirror Optics and Anti-Masking. Ceiling Mount Dual-Technology Digital Detector PIR Also, known as Duo-240, the digital detector is the smallest 360o ceiling-mount detector existing today in the market. The ceiling mount digital detector is designed to help avert false alarms in harsh environment settings that may be present in both commercial as well as residential use (Lecomte, 2009). Underlying principles The underlying principles is that of combing the sensors into a single unit where a passive infrared also known as PIR sensor and microwave sensor that complements one another. Additionally, it has developed patented technology such as cutting-edge microwave DRO front-end that uses the digital indication processing as well as true signal recognition through the help of fuzzy logic algorithm (Davies, 2008). Strengths One of the strengths of this type of dual technology sensor is that it is designed with a miniature size of about 8.6cm as well as it has a sleek sophisticated design (Kalender, 2011). Also, it has a detection pattern of up to 9m with a 360o sensation. Furthermore, it can effortlessly be fitted in any of the ceilings up to the height of 4.5m. Additionally, it can withstand harsh surroundings thus making it more durable to be used both at the office, residential as well as commercial. Finally, the detector enjoys high recognition accuracy with false alarm immunity as well as definitive long-term reliability. Lastly, the sleek and elegant shape blend easily and seamlessly into any décor thus making it easy to install in any ceiling, hence, helping in detection patterns with floor coverage of height 10.8m. Vulnerabilities The detector has very little exceptional capacity to differentiate among the motion of a human being and any other disruption Microwave with Sealed Optic Wide Angle Quad PIR Grade 2 It is a type of detector that has patented Anti-Crosstalk technology that helps to avoid false alarms that may rise from microwave interference with numerous sensors operating in the same place. Underlying principles It uses the QuadZone Logic that helps to discriminate between other sources of infrared and humans. Additionally, the detector has a ZoDIACDT which has microwave/PIR that offers brilliant false alarm immunity besides preserving superior catch performance. Strengths The detector has both the microwave as well as PIR X-band microwave techniques as it is microprocessor grounded. It also has complete temperature compensation with a color LED signal for relaxed walk test. Lastly, it has a standard model with Quad Zone Logic Accessories ceiling and wall mounting bracket with a noise reduction circuit of MX-400Z coverage (Sato, 2010). Vulnerabilities The detector microwave range can also be easily adjusted, besides it has a low power consumption with a tall RF immunity of 25v/m that helps it with its anti-fluorescent interference. Mirage Pet Immune Dual Technology Detector It is one of the superior dual technologies as a result of the advanced PIR optics and microwave design. Underlying principles It uses the Patented 3D holographic visual technique with EN 50130-4 FTA indication to offer a superior detection. Strengths By maintaining a catch performance it provides a higher level of pet immunity thus reliably flouting animals up to 45 kg. Through the adjustable monitoring height, the detector is able to perform digital signal processing through the three LED displays. Vulnerabilities The detector has numerous adjustable microwave range with a digital temperature compensation as well as patented tamper-proof bracket with cable feed Digital Dual Tech & Combined Non-Overlapping, with Anit-Mask, PIR & M/Wave Detection It is a type of detector in one casing with non-overlapping fields of vision as well as distinct relay outputs that offer an easy solution to sequential confirmation. Underlying principles It uses self-regulating relays dual technology; mask relays TMD method as well as PIR. Strengths The detectors apply the anti-masking method of detection that makes it ideal for high-security settings or location that may pose a high risk of masking. With a volumetric coverage of 15m in both of the lenses, it is one of the best detectors for hostile surroundings. The area in front of KX15DTAM can be examined constantly and distinctly from its normal style. Through the auto-sensitive part, the detector can spontaneously adjust some of its sensitivity selectable EOL regulators. Furthermore, the detector can easily combine the selectable alarm controller values of 6k8,4k7,5k6 as well as tinker values if 5k6,2k2 and 1k thus, providing for a maximum of the control panel on the market (Johnson, 2012). Through the patented technology by Pyronix, the sensor is able to react to ecological fluctuation by spontaneously altering its levels of immunity to background interference. The anti-blocking techniques offer stalling recognition up to a height of 15m in a defused mode, for instance, if the area of view is blocked when the system is being equipped, the process of disarmament will not take place pending the blockage has been detached. The digital temperature compensation is applied in hot surroundings thus it helps to regulate the sensor’s sensitivity giving room to uphold its array even when the related room temperature is almost at par to the exterior body temperature. Finally, the detector has a triple analysis that guarantees that an alarm will not take place unless all the three detector parts are activated in a specific pattern. Through the model, a detector is capable of providing incomparable stability in the removal of false alarm stimulations. Lastly, its QuadLED warning offers a signal for all detectorss and technologies. Vulnerabilities . Any invasion into this part often triggers the anti-masking development that helps to distinct trouble and mask output. Digital Combined PIR and Microwave Detector It has a volumetric detection coverage of 15m that is perfect for security of rooms as well as offices. It also incorporates selectable alarm resistor that assists in influencing panels on the market. Also, the modern 3D optics system enables perfect converging of the infra-red signal onto the pyroelectric sensor (Steigner, 2010). Hence, allowing BWT to visibly recognize both the negative and positive signal edges. Furthermore, the powerful software that is embedded into a microprocessor is applied to help process the received information from the pyroelectric sensor. Hence, resulting in a class of lower infra-red signal noise amplification thus helps in better immunity. Finally, depending on the atmosphere settings the detector will spontaneously modify its sensitivity. Lastly, whenever there is no activation after a five-hour timeframe the detector will essentially self-test both the microwave as well as PIR. Through, its range of frequencies bands it can prevent disturbance between detectors that are installed in the same area or location. Vulnerabilities Often very slow movement through the detection area requires the intruder to remain in the area for a long time thus might allow detection with a different method. Twin Technology Infrared & Microwave Detector The Twintec indoor detector is one of the state of the art detectors with a combination of both the passive infra-red and microwave techniques (Hsieh, 2009). It is through this combination of both the PIR and microwave into a solitary unit that is able to sense an impostor. However, one must note that these combined techniques are applied where the surrounding of the installation to be safeguarded is very turbulent. Furthermore, the 460 provides remarkable value for money with numerous features incorporated to provide a high level of security advantage. The detector has a coverage sequence of 12 meters by 90o that can be accustomed to suit your installation needs with temperature compensation as well as a cutting-edge white light filter incorporated to help reduce false alarms. Strengths The detector has an incorporated digital processing technology that assists in detection accuracy. Furthermore, the design is well shaped to fit perfectly with any décor that aid in true motion recognition. Additionally, the detector does not need PIR adjustment since it has a solid state relay for a silent operation that aid in self-test on power up through its remote walk test (Martinoff, 2009). Vulnerabilities The performance of the detector system could be degraded if the maintenance of the lens cleaning and replacement of the bulbs are not done in time. Microwave Combination Detector The detector was developed to sense on severe surroundings as a result of its established alarm applications. Strengths The detector has RXC-DT that provides for advanced microwave techniques to the PIR model to complete its three detection equipment’s (McCollough, 2009) Dual Tec, Motion Sensor with Mirror Optics and Anti-Masking This type of detectors is usually intended for mid to high-end commercial settings where often a grade three structure may be needed. It provides a reliable security with enhanced false alarm immunity via patented solutions. It also has a dual-core processing that is suited for locations that are challenging to safeguard with a sum of 5 patented solutions to enhance installation and reliability. Strengths The detector has an installer which profits from the shape of the detector that gives room for easy access to the connectors with its plug-in framework (Boas, 2011). Additionally, the motion sensor provides combined modern EOL resistors that help to improve walk test features thus assist in saving time on its installation. Lastly, through DT8016AF5 the detector is able to achieve its optimum performance by applying the X-Band microwave techniques as well as uniform sensitivity optics (Garcia, 2009). Vulnerabilities Performance is directly affected by the maintenance of the sensor and the microwave system. Conclusion and recommendations In summation, dual technology devices often involve the use of both the PIR and microwave, thus when combined these sensors offers a speedy detection rate as well as high immunity to false alarms, hence helps to lower call out costs or spending. By combining both the PIR and microwave the opportunity to develop numerous systems has risen as these are a good framework for creating prototypes of the actual systems. Therefore, the sensor should often be integrated to a component of the detectors that automatically performs a task by detecting an item in a particular area or locations. Thus, the different types of detectors form a vital element of the safety, home control, energy efficiency as well as other significant systems (Schindera, 2010). References Coursey, C.
