Color problem: All the black and white cameras are infrared sensors, infrared light in the visible light color camera in terms of the conditions for a stray light, color cameras will reduce the clarity and color reproduction, color camera filter is blocked Infrared imaging participate infrared sensor in order to make a color camera are now two approaches, the first switching filter, blocking infrared enter under visible light conditions;. Remove the filter conditions in the absence of visible light, so that the infrared entered, this kinds of programs get good image quality, but the cost is high and the switching mechanism causes a certain failure rate. The second monitor maintenance fees, open a particular passage in the infrared filter, allowing the same infrared wavelengths of infrared light light come in, this approach does not increase costs, but slightly worse color reproduction. Monitoring system of maintenance solutions for a long time, because the maintenance monitoring system is not addressed, causing a lot of monitoring equipment was damaged just put into use to monitor maintenance, a source in Zhengzhou monitoring equipment package as the first-year maintenance stated reasons are: First, the control part of the monitoring system maintenance work is not enough to face intelligent monitoring maintenance companies, that do not need to put too much human, material and financial resources, and thus ignore the monitoring system measures governance initiatives in the governance process, resulting in the latter part of the system management and maintenance can not keep up. Second, there is no one perfect, planned maintenance of monitoring equipment to implement the program. Monitoring the number of devices up to hundreds of clothing city, and maintain distributed throughout the mall, the device is a difficult and important work in the classification of these monitoring devices and develop maintenance programs, the complicated work has become principled, Clarification. While maintaining the efficiency of the monitoring equipment when a maintenance record sheet thrown fault, professional technicians can quickly call up the relevant technical parameters of the equipment, performance indicators and other relevant information, and to take appropriate measures to safeguard the effective progress of the device. Third, procurement monitoring equipment considered excessive cost devices while ignoring the latter part of the monitoring system and equipment maintenance and repair. Monitoring equipment brand too much, too much product suppliers, aftermarket manufacturers safeguards are not in place and other reasons, the monitoring device after a period of time, equipment failures continue, the failure rate rising, not differences error ultimate large original equipment update , thrown duplication of investment, extravagant grim phenomenon. Monitoring maintenance record sheet _ source maintenance (certified) _ monitoring maintenance provided by Zhengzhou source maintenance Electronic Technology Co., Zhengzhou source maintenance Electronic Technology Co., Ltd. (www.hnxywb.com) is a leader in Zhengzhou, integrated monitoring system, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In leading source maintenance staff warmly welcome all inquiries negotiations to create a better source of future maintenance.
