High score ~ ~ Understand the selection and budget of monitoring system. ...

Video surveillance system is an important part of security technology system, an advanced and comprehensive system with strong defense capability. It can directly watch the situation of the monitored place through the camera and its auxiliary equipment (lens, etc.). ) at a glance, at the same time, it can record all or part of the images of the monitored place, which provides convenient conditions and important basis for dealing with some events in the future. At the same time, the TV monitoring system can also cooperate with other security technology prevention systems, such as burglar alarm, with stronger prevention ability, and can find hidden dangers of accidents and incidents in time, prevent damage and avoid adverse effects? .

Second, the project overview?

In recent years, with the rapid development of social economy, science and technology, the living standards of urban and rural residents have been significantly improved, and the living conditions have been continuously improved. People have higher and higher requirements for security technology prevention, but the means of crime are also changing. After solving the housing problem, people are more and more concerned about the safety of housing, because criminals often choose residential areas as the target of attack, and cases of burglary, robbery and murder occur layer by layer. In the past, the preventive measures based on community security and civil air defense have been far from meeting people's safety needs. In order to crack down on all kinds of economic crimes, protect the life and property of the country and people, and ensure the normal operation of all walks of life and social departments, it has become the development direction in the field of security prevention to prevent and stop all kinds of crimes by using high-tech means.

X community is located in a prosperous area, and the people entering and leaving the community are very complicated. In order to protect the owner's personal and property safety, prevent and stop crimes such as invasion, theft, robbery and destruction, and facilitate property management, a video monitoring system is specially prepared to monitor the main roads, entrances and exits, parking lots, elevator cars and unit doors of the community. As the main control room, the duty room in the residential area is displayed on the TV wall at the same time of video recording, and as the sub-control center in the property office, some important images are displayed by TV switching.

Third, the system topology diagram

Four. Design principles and foundations

1, design principle

According to the overall structure of the community, and taking full account of the actual situation on site, the design front-end adopts Kingvee brand HD color camera produced by Beijing Xinzhiheng Technology Co., Ltd., the video transmission adopts twisted-pair transmission with anti-interference, long transmission distance and small signal attenuation, the control system adopts Xinzhiheng's Kingvee KV-J64Z series matrix, and the video recording system adopts Xinzhiheng's Kingvee digital hard disk video recording host, which can realize local.

A: Advanced nature:

When the investment cost allows, the system adopts advanced technology and equipment, which can reflect the advanced level of the system on the one hand, and make the system have strong development potential on the other hand, so that the system can adapt to social development as much as possible.

B, is it? Reliability:

The most important thing of the system is reliability. Once the system is paralyzed, the consequences will be unimaginable, so the system must run reliably and continuously. Under the condition of acceptable cost, the system design is strictly required from the aspects of system structure, equipment selection, technical service and product supplier's maintenance response ability, so as to make the possibility of failure as small as possible. Even if a fault occurs, the affected area should be as small as possible.

C, is it? Security:

The security performance of the security system itself can not be ignored. When designing the system, various measures must be taken to prevent illegal destruction of the system in various forms and ways.

D, is it? Scalability:

The future development needs should be fully considered when designing the system, and the system should have the possibility of expanding and upgrading the spare capacity.

E, is it? Normative:

Because this system is a strict comprehensive system, we should refer to various standards and specifications in the process of system design and construction, strictly abide by various technical regulations, and do a good job in standardized design and construction of the system.

Starting from reality, the intelligent system has high practical efficiency. This is also the key to the rapid rise and development of intelligent buildings today.

2、? design basis

The design of this scheme is based on Party A's routine requirements and follows the design specifications formulated by relevant state departments as follows. Mainly includes:

①? JGJ/T 16-92 Code for Electrical Design of Civil Buildings

②? GB/T503 14-2000 Design Standard for Intelligent Buildings

③? GB50 174-93 Code for Design of Computer Room

④? GB50057-94 Code for Lightning Protection Design of Buildings

⑤? GBJ232-92 Code for Construction and Acceptance of Electrical Equipment Installation Engineering

⑥? GB4943-95 Safety of information technology equipment (including electronic equipment)

⑦? GB/T75-94 Safety Technical Precautions.

⑧? GB50 198-94 "Technical Code for Civil Closed Circuit Television System Engineering"

⑨? General requirements of customers for CCTV monitoring system

Verb (abbreviation of verb) design scheme (refer to the plan)

Plan (omitted)

The video monitoring system is mainly composed of camera shooting, transmission, display and recording, local master control and remote control.

5. 1, camera part

The camera part is the front part of the TV monitoring system and the "eye" of the whole system. It is arranged in a certain position of the monitored place, so that its field of vision can cover all the monitored parts. Sometimes, the monitoring area is very large. In order to save the number of cameras, simplify the transmission system and control display system, install appropriate lenses on the cameras to make the scenes observed by the cameras clearer.

This video monitoring system has 57 video monitoring points, including 6 mobile points and 5 1 fixed points, which can cover the main intersections, entrances and exits, parking lots and all elevator car doors and unit doors in the community. In order to meet the customer's needs and pursue the overall aesthetic effect, Kingvee HD color or black-and-white camera from Zhi Heng is used. The specific installation location and quantity are shown in the following table:

Installation location? Camera type? Camera model? amount

At the gate of the community? A special camera for taking license plates? KV-C2092？ 2

Main intersection? Color to black lightning camera? KV-C2036？ four

Parking lot? Constant speed global camera? KV-C8609Q-C22？ 2

Perimeter? Infrared constant speed spherical camera? KV-C8609R-SN480？ four

Unit door? Infrared hemispherical camera? KV-C6082R？ 12

Elevator car? UFO camera for elevator? KV-C6033？ 33

In a word, the camera, like the eyes of the whole system, turns the content it monitors into an image signal and transmits it to the monitor in the control center.

5.2, transmission part

The transmission part is the transmission channel of the system image signal. At present, TV monitoring system mostly adopts video baseband (coaxial cable) transmission mode. If the camera is far away from the control center, twisted pair transmission or optical fiber transmission is also used.

This system is a monitoring project in the community, and the front camera is far from the monitoring room. If coaxial cable is used for transmission, the signal attenuation is relatively large, which can not meet the customer's image quality requirements, while optical fiber transmission is too expensive. Therefore, an economical twisted pair is used for video transmission. The key requirement for image signal transmission is that the image signal will not produce obvious noise and distortion after passing through the transmission system, and the clarity and gray level of the original image signal will not be significantly reduced.

In order to ensure the normal power supply of all front-end cameras, distribution boxes are set around the entrance of the community, main roads, parking lots and cameras. Provide 220V from the central control room to the distribution box, and change from the distribution box to 12V or 24V to the camera. In addition, a distribution box is installed at the door of each unit to supply power to the elevator car and the camera at the door of the unit. The power cord of RVV2* 12 is used from the central control room to each distribution box, and the power cord of RVV2*0.752 is used from the distribution box to each camera.

The front-end spherical pan-tilt cameras are controlled by 485 bus and RVVP2* 12 control cable.

5.3, display the record part

In this scheme, the digital network hard disk video recorder and monitor dedicated to Xinzhiheng Kingvee are used to display all the camera signals, and the hard disk is equipped with corresponding capacity according to the demand for video data storage time. At the same time, it also supports remote video transmission through the network, which is convenient for relevant leaders to access the local network hard disk video host anytime and anywhere through the network and watch real-time pictures.

In order to make the display more convenient and intuitive, a new video switching matrix (KV-9064V 16M) and a 13 display (one for 42 inches and one for 12 2 1 inch) are used to automatically switch and display important pictures, which makes the personnel on duty more clear.

5.4, control part

Because the spherical pan-tilt camera is installed in the parking lot and its surroundings, the personnel on duty need to track and monitor quickly when encountering suspicious personnel or emergencies, and the personnel on duty in the property office can also control the spherical pan-tilt camera at the front end if necessary, so Xinzhiheng's video switching matrix (KV-9064V 16M), main control keyboard (KV-2820KB) and auxiliary control keyboard (kV-2850) are adopted.

4. Infrared constant-speed spherical camera (KV-C8609R-SN480)

As an innovative patented product, this series of infrared lamps completely solved the night lighting problem of spherical pan/tilt. The side shaft linkage mechanism ensures that the projection of the infrared lamp is always consistent with that of the camera. The pictures overlap and the arrangement of multiple light fields ensures that there is no dead angle in the vertical direction. The cage lamp holder structure makes full use of the space between the upper cover and the interlayer of the spherical holder. Equipped with up to 160 high-power infrared diodes. Gundam? Actual distance 100 meter

The lamp tube adopts grouping power supply mode, and the overall failure probability is extremely small; Compared with other single-space structures, the heat dissipation area of large-scale upper sandwich structure is more than 3 times; Each lamp tube is hung independently and mutually independent, and there is no mutual heat collection phenomenon of centralized welding and installation of a single PCB board; Constant current source drive ensures that the infrared lamp tube works in a single constant current state under any external conditions, which effectively avoids being widely used today. In the widely used constant voltage driving mode, there is a vicious circle among temperature rise, negative temperature characteristics of the lamp and current. The above measures provide sufficient guarantee for the high reliability of infrared lamps.

Although the structure is complicated, it is extremely simple to use, and only one set of power cord provides AC24V power. The opening and closing of infrared lamp and the tracking of translation/tilt are completed automatically.

The pan-tilt machine core is connected with the machine body through a quick connecting plate, and an intelligent decoding board or a variable speed decoding board is integrated on the machine core.

The vertical rotation angle is 0-90 degrees, and the horizontal rotation angle is 0-355 degrees.

The well-known image processors in the security market are ROBOT, Sensormatic (sensormatic) and Panasonic. Among them, the robot image processor is the most widely used, and there are two kinds of image processors, which are original in the United States and assembled in China. The original robot image processor has the best performance, but the price is high, even higher than some embedded DVR. The performance of the assembly robot is slightly worse, and the price is only 1/2~ 1/3, so it is more popular. The appearance of digital video recorder makes the image processor market shrink gradually. With the declining price and increasing reliability of DVR, the image processor will eventually be replaced by DVR.

4. Monitor

There are many brands of monitors, such as Samsung, JVC, Panasonic, Sony, Sanyo, Li Lin, Bentai, Abel, Si Tong Sonik, SUNSPRO and Myway. Among them, Samsung display is more cost-effective. For example, Samsung SMC- 142P color display has good color reproducibility, long mean time between failures and high reliability, and is the first choice for monitoring system. Myway flat panel display in the United States (probably a brand launched by domestic companies) is well-known and beautiful in appearance, and it is also a good choice.

5, digital video recorder

Digital video recorders (hereinafter referred to as DVR) are mainly divided into two types: DVR built on industrial computer or PC platform and DVR without PC.

Japan, South Korea and European and American countries advocate embedded DVR that does not depend on any operating system. For example, Sony, Panasonic and Sanyo in Japan, Samsung, LG and POSWatch in South Korea, Sensormatic and DM in Europe and America have all launched multi-channel digital video recorders. The advantages of these DVRs are mature technology, clear video playing pictures, high system stability and reliability, good network transmission effect of some models, simple operation and so on. Disadvantages are that the total resources of the system are less (generally 50 frames/sec ~ 100 frames/sec), most DVRs can't display in real time when there are more than four channels, video playback is not real-time (25 frames/sec), the compression rate of image files is low, and the storage space in DVR can only store short-time videos.
