Installation Notes Due passive infrared detectors are passive infrared detector is a weak signal detection camera surveillance equipment maintenance, care must be taken in the installation of some of the details of the problems, such as high sensitivity and so on. A passive infrared detector is installed correctly, you must have the following information on several aspects: First, the performance characteristics of the detector must be aware of the monitoring maintenance of the manufacturers, and secondly to determine the location of reasonable intelligence surveillance installation maintenance companies, and finally must be carefully debugging . Detector alarm can not be said to explain installed, then how to determine the position of a passive infrared detectors installed it? Myth # 1 monitor purchase to replace the TV monitor; 2, a liquid crystal display or LCD TV to replace professional LCD monitor. This is mainly due to the difference between a normal user display equipment and professional security monitoring equipment is not enough in-depth understanding of cause, of course, the monitor manufacturer and the lack of pre-publicity specialized media also has a relationship. Relatively common display devices, professional security monitoring equipment has many special requirements, as long as they have a deep understanding of the special requirements for monitoring maintenance, it is easy to avoid these errors, including: 1, continuous high-reliability, high stability products ; 3, good heat dissipation 2, good handling, etc., to ensure stable operation; 4, interference and radiation effects; 5, multi-angle dynamic real-time monitoring; 6, special effects screen image (static or dark high demand fields, etc.); monitor maintenance factory | Source Maintenance (certified) | Monitoring maintenance provided by Zhengzhou source maintenance Electronic Technology Co., Zhengzhou source maintenance Electronic Technology Co., Ltd.
