I Project Overview

With the progress of the economy and the intensification of competition in the banking industry, bank service outlets (business offices, ATMs, self-service points) are covering every corner of the city at an unprecedented speed and number. This process brings more convenience to customers, while it brings a very tricky security problem to the bank security department. At the same time, due to the society some bad elements often maliciously destroy the ATM phenomenon is very common, and even the street homeless people also enter the self-service bank "lodging" or in the hot summer into the inside to avoid the summer heat, to the bank's security work to add a lot of trouble. In order to curb and combat crime and reduce financial risks, banks need to carry out effective and reliable monitoring of important locations and places of business to achieve the important locations and places of business audio and video data for video preservation.

The traditional analogue system can meet the demand of local monitoring in practical application, but it can't reach the remote network. And access to the bank's personnel is relatively complex, so this requires the bank to be able to monitor all aspects of the bank, based on the existence of these objective factors, Guangzhou Peak Fire Electronic Technology Co., Ltd. from the field of audio monitoring gradually extended to the IP network intercom system and network video conferencing system. From the design and development of products to the construction of software system platform, Peak Fire methodical development covers most of the regions in China.

Banks are located in all corners of the city and belong to the key security units of the country. Its monitoring scope is mainly divided into three major parts, teller monitoring, security monitoring and self-service area monitoring, where the teller monitoring is mainly to see the operation of the salesman's status and dialogue between the customer, so the development of the selection of Fiberhome pk series of high-fidelity, high-sensitivity noise reduction pickups; security monitoring not only to monitor the daytime business hall, but also to prevent the night invasion of illegal personnel, the door, the channel, and other parts of the 24-hour monitoring, therefore, according to the Fiberhome pk series. More to 24-hour monitoring, so according to the specific circumstances, the choice of type of camera; for self-service area is 24 hours are in business, can not physically prevent the invasion of illegal personnel, can only be real-time monitoring and video on the scene, and the internal staff of the money and release of money should also be real-time monitoring and video, of course, involves some of the passwords will be handled by some technical means, so that it can not be According to the different installation locations, all the front-end videos should be centralised.

Depending on the installation location, all front-end videos should be concentrated to the monitoring centre of the branch for video recording, in which the monitoring images of the security monitoring and self-service area should be able to be transmitted to the security office of the branch through the network.

Design Principles and Basis

1、Design Principles

According to the overall structure of the bank, and give full consideration to the actual situation of the site, the design of the front-end using Guangzhou City, Peak Fire's noise reduction digital pickups, digital hard disk recording host, you can achieve the local display, cyclic video recording, retrieval playback and remote access control and so on.

2, advanced:

In the case of investment costs permit, the system uses today's advanced technology and equipment, on the one hand, can reflect the advanced level of the system has, on the other hand, the system has a strong potential for development, so that the system in the longest possible time with the development of society.

3, reliability:

The most important thing is the reliability of the system, once the system is paralysed the consequences will be unimaginable, so the system must be reliable, continuous operation, system design in the cost of acceptance of the conditions, from the system structure, equipment selection, product suppliers of technical services and maintenance response capacity and other aspects of the system should be strict requirements, so that the likelihood of failure occurs as little as possible. Even in the event of failure, the impact should be as small as possible.

4, security:

For security systems, its own security features can not be ignored, the system design, must take a variety of means to prevent the system in various forms and ways of illegal damage.

5, expandability:

System design should give full consideration to the future development needs, the system should have a reserve capacity for expansion and upgrading possibilities.

6, normative:

As the system is a strictly integrated system, in the design and construction of the system should refer to the standards and norms in all aspects, strictly comply with the technical regulations, and do a good job in the standardised design and construction of the system.

Third, the design programme

This set of video surveillance system is mainly composed of camera part, transmission part, display and recording part network video remote transmission and other parts.

3.1, pickup part

Pickup is the front part of the television monitoring system, is the whole system of "ears". It is arranged in the place to be monitored at a certain location, so that its field of view can cover the whole of the parts to be monitored. Sometimes, the place to be monitored by a large area, in order to save the number of pickups used, generally take the array method of arrangement. Installation of pickups on the camera, so as to achieve the function of synchronous audio and video recording.

32, transmission

Transmission part of the system is the image signal transmission channel. Currently, most of the television monitoring system using video baseband (coaxial cable) transmission. If the camera is far from the control centre, there are also twisted pair transmission or optical fiber transmission.

This system for the bank's monitoring project, each front-end camera is relatively close to the monitoring room, the use of coaxial cable transmission, both economic, but also to ensure image quality, so the use of coaxial cable for video transmission, the transmission of image signals focus on the requirements of the image signal through the transmission system, does not produce significant noise, distortion, to ensure that the clarity of the original image signals and the grey level does not significantly degrade and so on.

All front-end equipment from the monitoring room to take a unified power supply, each monitoring system is equipped with a 12V10A power supply, through the RVV2 * 0.752 power line to supply the front-end cameras, due to the power supply of infrared lamps for the 220V, and therefore also use the RVV2 * 0.752 power line from the monitoring room to unify the power supply, in order to avoid interference, and the weak and signal cables are laid separately.

3.3, display recording part

This programme is designed to use digital network hard disk recorders and monitors to complete the display of the camera, and through the hard disk for video recording, according to the demand for the preservation of video data storage time equipped with the appropriate capacity of the hard disk.

3.4 Network video remote transmission part

This system in the local monitoring video at the same time, it also supports the video network remote transmission, to facilitate the relevant leadership through the local LAN or bank network with a legitimate identity to access the local network DVR host at any time and place to watch the real-time picture. With the appropriate authority can also be remote control management, online playback and previous video data download, etc., greatly improving the supervision of the upper levels, making the banking system run more secure.
