Since the reform and opening up, with the improvement of people's living standards, everyone's entertainment activities have become more and more abundant. Entertainment venues such as bars/KTVs have sprung up and sprouted everywhere. Such an entertainment place has always been an impetuous and unhealthy place in the hearts of the people. Most of these places are dimly lit. Guests are drinking and entertaining. They are in a state that is not easy to control. It is easy to be closely related to yellow, poison, black and other very things. Fights and vicious injuries occur frequently. For the stability of the country and the harmonious development of society, the relevant national administrative departments have issued policies and regulations to manage. The "Regulations" clearly stipulates: The singing and dancing entertainment venues shall install CCTV monitoring equipment at the entrances and exits and main passages of the business premises in accordance with the provisions of the public security department of the State Council. Singing and dancing entertainment venues shall keep CCTV surveillance video materials for 30 days for reference, and shall not delete, modify or use them 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? Engineers combined with years of design experience, and fully considered the user's various specific requirements and site specific conditions and carefully designed the system. Adopt advanced all-digital computer intelligent monitoring system, this system has the advantages of high reliability, strong scalability, high cost performance and so on; just as VCD player replaces the traditional video recorder, the all-digital computer intelligent monitoring system has the traditional analog monitoring system The unparalleled superiority can block security loopholes and eliminate disputes caused by the negligence of staff, provide evidence for emergencies, and protect the interests of investors.
1. Site demand analysis
Bar/KTV and other entertainment venues are generally divided into three parts: show stage, hall, and private room. According to the requirements, we need to conduct a comprehensive monitoring of the bar/KTV. Therefore, monitoring points should be arranged for the front door, rear door, hall, passage, private hallway, stairwell, etc.
2. Introduction of main products of network transmission equipment
1. Front-end access layer:

Safer: We all know that the 220V voltage is very dangerous. It is often the case that the power supply cable is damaged. This is very dangerous, especially in thunderstorms. Once the power receiving equipment is damaged, the leakage of electricity is inevitable. The use of PoE switches is much safer. First of all, there is no need to pull the power supply, and the 48V safety voltage is provided. The most important thing is that Tianbo PoE switches currently have professional lightning protection design, which greatly improves the reliability of the product. More convenient: Before PoE technology prevailed, most of them were powered by 220V power sockets. This construction method is relatively rigid, because not every place can pull power or install power, so the location of the best camera is often hindered by various factors. The location had to be changed, which resulted in a large number of blind spots. After the PoE technology is mature, these can be solved. After all, the network cable can also be powered by PoE. More flexible: The traditional wiring method will affect the networking of the monitoring system, resulting in the inability to install monitoring in some places that are not suitable for wiring. Using PoE switches to supply power can be independent of time, location and environment. The method will also be much more flexible, and the camera can be installed arbitrarily. More energy-saving: The traditional 220V power supply method requires a large range of wiring. In the transmission process, the loss is quite large, the greater the distance, the greater the loss, and the latest PoE technology uses low-carbon environmental protection technology, the loss is very small In the long run, energy saving and environmental protection can be achieved. More beautiful: PoE technology makes the network and electricity into one, so there is no need to wire and install sockets everywhere, which makes the monitoring site look more concise.2.
