Since the reform and opening up, as people's living standards have improved, everyone's entertainment activities have become more and more abundant. Bars/KTVs and other entertainment venues are sprouting all over the place. Such entertainment places have always been an impetuous and unhealthy place in the people's hearts. Most of these places are dimly lit, and guests drink and entertain themselves and are in an uncontrollable state. They are easily related to yellow, poisonous, black and other very important things. Fighting and fighting and malignant injuries occur more frequently. In order to ensure the stability of the country and the harmonious development of society, relevant state management departments have issued policies and regulations to manage them. The "Regulations" clearly stipulates that singing and dancing entertainment establishments shall install closed-circuit television monitoring equipment at the entrances and exits and main passages of business premises in accordance with the regulations of the State Council*s department, and shall ensure that CCTV monitoring equipment operates normally during business hours and shall not be interrupted. Song and dance entertainment venues shall keep CCTV surveillance video data for 30 days for future reference, and may not be deleted or used for other purposes.
In order to maintain public safety, strengthen the management of entertainment venues and ensure the healthy development of entertainment venues, it is very important to build a highly intelligent digital video surveillance system. How to build an efficient and practical video surveillance system? An engineer has carefully designed the system by combining many years of design experience with full consideration of the user's specific requirements and on-site specific conditions.
Adopting the most advanced all-digital computer intelligent monitoring system in the world today, this system has the advantages of high reliability, strong scalability, and high cost performance. Just as a VCD player replaces a traditional recorder, the all-digital computer intelligent monitoring system has a traditional The superiority of simulation monitoring system can not be compared, it can plug the security loopholes, eliminate the disputes caused by the staff's dereliction of duty, provide evidence for emergencies, and well protect the interests of investors.

Second, site demand analysis
Bars/KTVs and other entertainment venues are generally divided into three parts: performing arts, halls, and private rooms. According to the requirements, we need to conduct comprehensive monitoring of the bar/KTV. Therefore, front doors, back doors, halls, passages, private hallways, stairways, etc. must all be equipped with monitoring points, and some of them should be monitored using a PTZ camera.
The working hours of bars/KTVs and other places are dimly lit, and when the DISCO lighting is turned on, the lights instantly change rapidly; most of the working hours are also in a closed and dim environment. In terms of camera selection, I should mainly focus on low-light cameras and infrared cameras.
In order to ensure that relevant management personnel can timely check and monitor the actual conditions of the site, we use an online video server for the back-end host to not only monitor and store locally, but also access management centers at all levels of management to facilitate different management. Departments remotely monitor and access related information.
In the overall functional requirements of the intelligent image monitoring system, the specific description is as follows:
1. Picture effect
The picture is clear, with high resolution and vivid colors.
The picture window can be multi-stage zoomed in and out, and the operation is simple.
The screen can be adjusted in terms of brightness, contrast, chroma, saturation and other aspects.
Real-time monitoring of images in key locations.
Through the simple control of the hard disk host, you can freely look at a certain screen or choose the corresponding screen flexibly to participate in the cycle switch.
The frame rate of the picture is 25 frames/second, the image effect is very important
2. Image switching
The image can be manually switched between the user's own control at each monitoring point (it is convenient to select from the multiple images to switch the video image to be switched). The image can be set by the user (it is convenient to select from the multiple images to switch the video image to be switched) by the computer to automatically switch.
3. Image storage and playback, hard disk recording
The video surveillance system automatically stores digital images on the hard disk through system application software. The video can be played through the system playback software, and the playback effect is excellent. The system can use software to compress images in real-time into digital image formats and store them on large-capacity hard disks. According to the alarm information provided by the monitoring system, the video monitoring system can automatically perform on-the-spot video recording of the alarm according to a predetermined scheme in the event of an accident or failure of the production equipment.
4. Image processing
The system can save and copy images of important places. Simple operation and reliable quality.
5. Operation
Multi-level users can simultaneously monitor and control according to pre-set permissions. When multiple users are using at the same time, the picture is clear and the frame rate is 25 frames/second.
6. Historical data query
The system can record images and data within the user-specified time limit for easy query.
Third, the technical indicators of the main equipment of the system
Camera
The camera used in the system can choose color super low-light CCD camera, infrared waterproof camera, high-speed ball and infrared dome camera; color camera should have at least 420 lines of horizontal resolution, simple installation and maintenance. And it is better monitored when the light is dark and changes frequently. Realize all-weather monitoring. The camera's operating temperature is -10°C to +50°C.
2. Network video server
Each channel can achieve D1 resolution (PAL: 704×576, NTSC: 704 × 480), support dynamic IP address, support LAN, WAN, and multiple wireless network transmission; video bit rate is adjustable to support simultaneous access by multiple users, multi-level User password rights management.
3. Monitor
The monitor used in this system should have more than 480 lines of horizontal resolution, clear images, no distortion, and high color reproduction. Beijing Monitor Installation
4. Management server
Can set up and control any device, remote upgrade and other functions; support 1/4/9/16/36 screen single-screen display, and two-way voice intercom, electronic maps, log retrieval, alarm control, remote retrieval, etc. Features. Powerful, user-friendly, easy to operate, and convenient for users to realize the application of large-scale remote network monitoring system.
Fourth, system point setting summary
According to the above mentioned bar/KTV can be divided into the front door, back door, hall, passage, private room corridor, stairway, etc. should be arranged monitoring points for monitoring. According to the actual situation of these locations we can specify the position:
Entrances and exits: Because the front and rear doors have entrances and exits, the monitoring points need to be arranged outdoors, and an infrared waterproof integrated machine should be used. Infrared hemispheres can be used to monitor the entrance and exit passages.
There are two parts in the hall: the performing arts area and the audience area. We all recommend using super low-light cameras. In particular, the high-definition ultra-low illumination camera can be used in the performing arts area, so that the performing art scene (including the DISCO scene) can also be selectively switched to the display device of the hall through the video distribution apparatus.
Channels, private corridors, stairways: Infrared dome cameras/IR waterproof cameras can be used;
Cashier: It is recommended to use high definition low illumination hemisphere or infrared high hemisphere.
Outdoor parking lot or open space can be installed high speed ball / constant speed ball, to ensure the comprehensive monitoring.
