There must be a non-relevance consideration between the detection target and the environment: in the actual environment, there are many targets that may trigger an alarm or generate false alarms, such as harmless animals such as insects, birds, cats and dogs, vehicles in adjacent lanes, Pedestrians passing by, windy plants, high and low voltage electrical lines or radio wave launch equipment and lighting fixtures. Therefore, any infrared detector should not be affected by these goals. If you ignore this principle in your application, you may have constant false alarm rate.
Infrared detector setup environment must have a certain ability to block: Infrared detector setup, especially for point-to-point outdoor detectors, to achieve a real protective effect, in the installation environment should have a certain height or width, can not let the target Skipping or even skipping, this application principle is basic and necessary.
The detector setup must be invisible and invisible: Infrared detectors are expensive to install. Therefore, in order to make the detectors use non-intangible detection advantages, they must be concealed or the target not detected. Measured feelings, so we must be careful to do a good look and the environment with the landscape, to avoid causing unnecessary misunderstanding or to make the target wary.
The installation of the detector must consider the terrain elements: Infrared detectors will encounter the influence of the terrain in the use environment. Therefore, it must be noted that the difference in slope height, the height difference between ladders, and the height difference of two buildings or the terrain across the culverts There are no protection loopholes due to the impact of different application options.
The detector must be convenient for system integration and construction: Infrared detectors are usually not the entire protection system. They are usually used together with access control or video surveillance systems. In particular, the monitoring and video linkage signals must be synchronized in real time, so the signal linkage and connection Part of the design and construction must be very convenient for the system integration and construction of the project. Therefore, the interface structure of the detector must not only be suitable for various weather conditions, but also its signal format must be easily connected with various types of control devices.
The detector should be harmless to the human eye: Infrared detectors must first be considered harmless to human eyes in optical beam applications. This is an important consideration in the use of intrusion detectors. In the current market application of active detectors, a laser beam called a laser detector may cause damage to the human eye, even under normal active microwave detectors, it may also cause some damage to the human body. Therefore, in the application of the principle to avoid any harm to the human body beam.
The detector must have multiple detection application functions: due to the different environment and target intrusion methods, the functionality and the countermeasures on the infrared detector must be diversified, so the multi-detection method is also necessary for the detector application. The principle to pay attention to.
The choice of the detector must be a timely response: the detector is mostly located in a remote intrusion prevention zone, so the real-time nature of the alarm response is absolutely necessary. From the alarm to the confirmation is generally required to confirm the scene in a few seconds Real-time status content is used as the basis for processing, so real-time performance is also an important application principle of infrared detectors. In general, the sensing speed of the detector can transmit the detection signal from the detection end to the control panel within a few milliseconds. This is already a very fast transmission speed. However, due to the lack of an intuitive graphical interface, it is judged by the human eye that it will cause Due to delays, the real-time nature of infrared detectors is the key to the application of the product.
The more beams there are, of course, the more obstructive: Infrared detectors The principle of selection of beam wall detectors for single beam, double beam, four beam, or more beams is usually dominated by dual beam active infrared detectors. In terms of ergonomics, the detection area of ​​the human body is approximately 50-70cm in frontal width and 20-40cm in lateral width. If a wide range of environments is used, single- or dual-beam active infrared detectors may fail to block the upper half of the detector. One or both of the rays in the lower half generate an alarm miss report. Of course, the use of four-beam or more beam infrared detectors will reduce this missed probability.
The above are the basic principles for the application of infrared detectors in the selection of products. These principles are all matters needing attention in the application of products.
