Four system design

The network of Zeus Eye Kindergarten mobile video surveillance system is mainly composed of three parts: client, kindergarten and dynamic domain name server. The three parts are interconnected through the Internet and mobile GPRS and Unicom CDMA existing communication network. The specific network architecture is shown in the figure. Show.

The client is the device that the parent can use. It can be an ordinary operating system running Windows or a smart phone supporting JAVA/BREW/WINCE.

The dynamic domain name server is set up by Kejia Company and is provided to the kindergarten for direct use. The server is used to assign a domain name to the kindergarten's video server, so that a video server without a fixed Internet IP address has a fixed address that can be accessed.

The kindergarten side can be set up on the original LAN based on the kindergarten. Since the monitoring of the kindergarten belongs to the multi-user concurrent monitoring, it is necessary to consider the bandwidth requirement of the video server according to the actual size of the kindergarten, and the kindergarten applies for sufficient bandwidth to satisfy the video service. need.

The network installation at the kindergarten side needs to consider the following three main devices:

1, front-end equipment

There are front-end devices including cameras, pan/tilt, decoders, etc., which are used to capture continuous scenes of various scenes in kindergarten in real time, and provide analog signal input for the encoding server.

This program recommends the use of Kejia KOM-CP450E infrared dome camera, which has advanced system design, using high-quality circuit board and SONY CCD (optical image sensor).

Control design

Since each participating kindergarten is different, the engineering personnel will conduct on-site field tests according to the actual situation and multiple times, make full use of the resources provided by the kindergarten, and design the conformity based on “saving”, “environmental protection” and “energy saving”. Kindergarten monitoring program.

Five program features

The design of the scheme follows the principles of data security, information security, advanced technology, stable performance and cost saving, and comprehensively considers construction and maintenance factors, and reserves interfaces for future system upgrades and function expansions, so that the scheme has the following characteristics:

Security: The system uses multi-level encryption and multi-level authentication to communicate data and video to achieve data transmission security. It adopts advanced, mature and reliable products to ensure the accuracy, completeness and consistency of data. Quick recovery feature.

Convenience: Most parents' ability to use the computer is not very good, so the system uses a simple, graphical, fool-like operation, so that parents can use it very conveniently, and can quickly grasp the use method.

Stability: Most of the systems in the kindergarten end use mature and stable hardware devices, which do not require special maintenance. The equipment has a comprehensive system monitoring function, which can automatically repair the system in case of system failure to ensure 24 hours of trouble-free operation of the system.

Advancement and applicability: The system integrates many advanced technologies in the world, reflecting the latest development level of current electronic technology, computer control technology and computer network technology, and adapting to the requirements of the development of the times.

Economical and practical: fully consider the actual needs of users and the development trend of information technology. According to the user's site environment, design and select the system configuration scheme suitable for the site situation and meet the user requirements, and achieve the best performance through strict and organic combination. The price ratio, in order to save engineering investment, while ensuring the requirements of system function implementation, economical and practical.

Scalability: The system design has the possibility of updating, expanding and upgrading in consideration of the future development and use of technology. According to the actual requirements of the project in the future, the system functions will be expanded. At the same time, the scheme will be redundant in the design to meet future development requirements. Partial, modular, and hierarchical system planning and design provide great convenience for normal use and fault detection.
