China's hotel industry has experienced a period of rapid development since the 1990s. With the progress of society, tourism and business travel needs, the hotel is spread all over the streets, from high-end star hotels to business chain hotels, according to statistics, the current domestic various types There are 270,000 accommodation facilities, less than 20,000 star hotels, and more than 1,000 tourist resort hotels.
In order to meet various customer needs and hotel operating needs, the hotel is divided into commercial hotels, tourist hotels, resort hotels, residential hotels, road hotels, etc., in addition to the star classification. The different hotels meet different types of customers, the main There are also differences in the way. With the development of information technology and the popularization of network technology, more and more hotel managers have proposed the construction of hotel intelligence. Apart from the hotel's own customer's living experience, how to build a more intelligent information hotel has been cited as the cusp.
An Introduction
Dahua Hotel's comprehensive security comprehensive management system mainly includes video monitoring system, access control system, alarm system, ladder control system, intelligent parking management system, and is based on TCP/IP network technology to form a network, using an integrated software and hardware platform to integrate multiple children. System, at the same time with the center management system and large-screen display system, as the monitoring center of the hotel security system
Multi-service system
Hotel security involves a variety of subsystems, including video surveillance systems, alarm systems, intelligent analysis systems, intelligent parking systems, card systems, etc., each subsystem is interconnected and interoperable, and can operate independently, modular integration, and each subsystem can The video system forms an effective linkage.
Economic and practical
Taking full account of the actual needs of the hotel system and the development trend of information technology, based on the site environment, design and select system features that suit the site conditions and meet hotel monitoring requirements. Through a rigorous and organic combination, achieve the best performance-cost ratio, in order to save the project Investment, while ensuring the implementation of system functions, is economical and practical.
Unified management
The equipment involved in the system can all be monitored, controlled and managed through the same platform.
Friendly operation
The system operator can operate the system by controlling the keyboard (and direction bar or direction ball) or the keyboard and mouse of the multimedia workstation: select the camera and control the camera (when there is a head, the angle and azimuth can be adjusted; when the lens is zoom type, Adjustable focus, focal length, etc.), select the monitor, etc.
Operation record protection
Real-time recording of real-time image of the main channel, which is recorded on the disk when the system is started, running or any system error, operation error, warning, and hardware failure. The record includes the time, status, reason, and the corresponding hardware number. At the same time, it is also necessary to record the operator's login, menu operations, and alarm generation and processing to prevent malicious counterfeit operations. The operator must enter the system by logging in to verify the identity and password, and can set operations on various operations. The person's control level and operation password prevent illegal operations.
Information record protection
The design of the hotel system has high reliability. After system failures or accidents are interrupted, it can ensure the accuracy, completeness and consistency of the data, and has the function of rapid recovery. At the same time, the system has a complete set of system management strategies. , can guarantee the safe operation of the system. Maintain the original integrity and real-time information, storage time is not less than 30 days.
