I. Project Overview
The establishment of a provincial-level city video surveillance system, divided into secondary monitoring centers, a total of 1500 heads, the establishment of such a large-scale video surveillance system, which method is required? The following three system functions of video monitoring are compared.

We will monitor according to monitoring type divided into site availability monitoring and server monitoring two categories, each category has a variety of user-configurable monitoring types to choose from, detailed description as follows:
1 Site Availability Monitoring
the powerful supplement, compared with satellite remote sensing and manned aircraft remote sensing, more convenient, fast, fast response, its survivability, low demand for climatic conditions, the terrain adaptability, At the same time, we can realize the real-time transmission of image data and meet the requirements of emergency conditions.The high-precision digital imaging equipment equipped with unmanned aerial vehicles, with area coverage, vertical or oblique imaging technology capabilities
First,Cacti/nagios/zabbix/centreon/gangliaThe Choice1,CactiCacti is a set of graphical analysis tools for network traffic monitoring based on PHP,MYSQL,SNMP and RRDTool development. to put it simply Cacti is a PHP program. It obtains remote network devices and related information by using the SNMP protocol (which is actually obtained using the Snmpget and snmpwalk commands of the NET-SNMP software package ) and RRDTOOL tool drawing, shown through PHP
At present, many enterprise information systems have their own monitoring platforms and monitoring methods. no matter which method is used to achieve real-time monitoring of the system and fault alarms, there are only two methods used: centralized Monitoring and distributed monitor
High-speed IT system after the completion of the operation and maintenance management work will be quickly mentioned on the agenda, relying on simple human protection, operations and operation of the work of the staff to rely on personal experience, operation and maintenance work scattered, and always in the aftermath of the passive state of fire, can not adapt to the business system stable operation of the security requirements.1.2 Building GoalsIn order to make Jiangxi high-speed IT infrastru

At present, there are many open source free products on the market for enterprise monitoring, but sometimes it is difficult to find a practical and convenient software, many open source software only focus on a point, maybe do well, but many times the enterprise needs is a face, so that the enterprise will deploy a lot of software to support the operation of the system, This is not all, often a lot of open source or free software configuration is more

Erlang supports monitor and link two monitoring processes so that all processes can be connected as a whole. When a process exits with an error, the monitoring process receives a message notification that the process exits. With these features, it is not difficult to build a simple, robust system using Erlang. In the previous article, we analyzed the usage of two methods, and analyzed the implementation of

The development of wireless network technology leads to the maturity of wireless video technology. For the digital information age, the perfect combination of digital video monitoring and wireless network technology will certainly produce more powerful technologies.
Video Monitoring is an intuitive and convenient way to record detailed information and provides real-time
With the increasing popularity of multicore CPUs, more and more Java applications use multi-threaded parallel computing to give full play to the performance of the entire system. The use of multithreading also poses a huge challenge for application developers, and improper use of multithreading can lead to thread deadlock or resource contention, leading to system paralysis. Therefore, a run-time thread monitoring tool is required to help developers di

Monitoring is the core task of cluster management. Monitoring data can be used for scheduling tasks, load balancing, reporting hardware and software failures to administrators, and extensive control of system usage. Monitoring information must be obtained without impacting the performance of the cluster. This article discusses ways to obtain
