Substation applications, video intercom system, video intercom access control access control system is mainly responsible for personnel access case records by authorized cardholders by credit card, and out of different substations, electronic access control systems used in conjunction with traditional mechanical locks to ensure that the front-end substation and out safely. In the monitoring center, centralized management software integrates access control function, you can browse access records, query access control events by setting focus to achieve access control linkage arm and disarm the menu, the software remotely open the door. Truly access control systems and ring, video, alarm, control a variety of functions for seamless integration. Access management also supports linkage macro command. 2, modular design. The system uses a modular design, the system is divided into audio and video surveillance modules, environmental power monitoring module, integrated alarm processing module and access management module, network transmission module. Between the various modules both independent and seamless integration, any one module is not an independent system, the mutual interaction between the features, such as credit card linked to disarm the alarm system, cameras capture video linkage, linkage lights turn on. On the other hand they are independent of each system, each module can fail without affecting the functions of other modules, the system is more stable and secure. 3, centralized management. Unmanned substation, involving video, power, environmental, alarm, access control systems, only a set of software, a host, you can achieve the monitoring system monitoring and management of all devices. Many manufacturers on the market to solve the unmanned substation video, ring, access control, alarm systems require multiple hosts, several sets of software before they can realize the management dilemma, truly integrated management of multiple systems. 4, seamless integration. A single set of system integration of the following features: DVR video storage, network transmission function; ring host environment real-time detection / power variable; arm and disarm the alarm host integrated centralized alarm management; access control access control management; data anomalies, alarms and other police intelligence macro linkage order to achieve the implementation of emergency plans; SMS notification function; remote control function; distributed centralized storage; ring data overlay video capabilities; core host offline networking, HTTP functionality. 5, easy to use. The user from the tedious operation of the system out of operating a system to enrich macros alarm management, making it easy to use, no more than one operating system, no return call various functions, with macros feature, simply set the alarm linked to macros, macro commands one by one to perform pre-set operations, such as: call preset, capture, video, turn on the switch output, send text messages, instant alarm, real evidence.
