subject: Burglar Alarm Detector And Installation And Attention - Security Industry - Remote Duplicator [print this page] A perfect anti-theft alarm system, the implementation of function, system stability, the key depends on the detector installed in the front of the good performance and stability. Anti-theft alarm system functions in addition to outside, the two most crucial indicators of false positive and false negative rate is. These two indicators is inconsistent and uniform, to distinguish the various brand product quality and grade of the most important factor.
A high-end brand, excellent products, must be able to achieve a low false alarm rate, low false negative rate, otherwise it could not be called high-end products. In our view, the current domestic many users do not fully understand this. How to make rational consumption, with a scientific and rational point of view to understand a brand, a product, we talk about their views on this. As the saying goes: Open the windows that light, then break apart pastry that stuffing.
1, the detector and the principle of
A wide range of detectors, including indoor passive detectors, outdoor passive detectors, outdoor active detectors and environmental detectors and so on. Environmental detectors are generally common vibration detectors, smoke detectors, gas leak detectors, along with strong electronic detectors, hazardous gas detectors, pressure, temperature detectors and so on.
Detector works is nothing but the signal acquisition, signal processing and signal output. These three aspects of the decision of the quality of the detector is critical. Error signal will inevitably lead to the acquisition errors in the signal input to signal processing more inaccurate, then the error output. Some users in the choice of detector may focus on the one hand, indicators such as pay attention to the false positive rate of false negative rate of neglect. Lead to erroneous input of factors including: whether the rational design of the detector housing, the choice of high quality infrared sensor head (pyroelectric sensor), whether the design requires the use of a professional optical lens, the detector is a recognition on the environment, etc. . In short, the correct understanding and identify good products, so that rational choice and consumption is important.
2, how to properly install and use the detector? Should pay attention to what matters?
Detector installation and use of some basic principles. Proper use and installation of detectors can be designed to maximize product functionality, and reduce the false negative rate of false positives. These principles and considerations include:
First, choose the most suitable detector detection function.
Captured by the detector signal detection method is divided into Shuangjian detectors and infrared detectors (single-Kam). As a professional manufacturer, our definition of Shuangjian detectors including infrared detection is the detection method and microwave detectors. Both units infrared, dual infrared or four element infrared, this is a way of microwave is another way. At present, some manufacturers have introduced the so-called non-professional three-mirror, four Kam-detector, which is a scientific argument. In fact, the so-called "Kam" is the recognition, identification of meaning. Detector in signal capture, nothing less than the only two ways: identification of microwave and infrared identification. Some products to micro-processing, anti-signal processing for pets all called "Kam", so-called three-mirror, four Kam detector. Our company has an AM Meeting Feng range of products, technologies used, including dual infrared, microwave detection, anti-blocking, anti-pet, and has micro-processing technology, so it can be called "Six Kam Detector" mean?
As a general home use, we recommend to infrared detectors based, Shuangjian secondary detector. Premises for commercial purposes, such as companies, factories, shopping malls, military, schools, banks and government agencies, etc., we propose to Shuangjian detector-based infrared detectors supplement. Anti-block detector for high-risk areas, such as treasury, robbed library, magazines, etc., but not recommended on other occasions.
Second, select the installation method with an appropriate detector.
From the installation, the detector is divided into wall mount and ceiling mount detector, referred to as wall and ceiling detector detectors.
Wall installation due height detector is usually 1.8 meters to 2.5 meters, the detection range of 8 meters, 10 meters, 12 meters, 15 meters and 25 meters, suitable for small sites in the installation of high use. Such as room height of 2.5 meters of space, wall detector detectors than the ceiling better.
