Traditional analog cameras are unable to meet the demand for high-definition image capture. High-definition video has become the mainstream of video surveillance today. To achieve high-definition video surveillance, high-definition video cameras can not be separated, so the megapixel HD network camera products came into being.
The emergence of megapixel HD cameras laid the foundation for the realization of high-definition surveillance solutions. What is a megapixel HD camera?
Megapixel HD camera, HD video camera based on IP network transmission. Take an example of a typical high-definition network camera as an example. From the front to the back, it includes a lens, an infrared cut filter, an image sensor, a clock synchronization and image processing codec, a power supply, and an I/O network interface board, as shown in Figure 1. .
Among all the components, the most critical one is the image sensor. The excellent or bad indicators directly affect the HD network camera screen effect. Currently, most HD network cameras on the market use CMOS as a light-sensing element. However, compared with CCD sensors, their application in high-definition network cameras has advantages.
Millions of camcorders have many advantages, and the status of multiple applications is well known. Compared with the traditional monitoring systems, the network million high-definition surveillance cameras have many advantages, such as reducing the types of lines, easy to install; can be easily integrated with other computer network applications; Two-way communication; image storage, transmission and management is simple and reliable; monitoring points can be flexibly increased; high performance, low cost, and low maintenance and maintenance costs. It plays an important role in traffic monitoring, medical monitoring, and shop monitoring.
Traffic monitoring: In China, many major cities including Beijing, Tianjin, and Shanghai have installed monitoring equipment on the main traffic lines, and some national roads have also installed monitoring equipment. According to forecasts, local traffic monitoring systems and national long-distance automatic traffic monitoring systems will become hot spots in the near future. The concept of intelligent transportation has become a hot spot in the development of modern economy. The modernization of urban transportation will produce a huge demand for electronics and communication equipment.
The monitoring of road traffic has been a topic that has been proposed for several decades. Until now, TV surveillance equipment has only been installed on major trunk lines in major cities. The main obstacles lie in both technical and cost aspects. In this area, network million HD surveillance cameras will be excellently applied due to their obvious advantages in terms of performance and price. On the one hand, the network million HD surveillance cameras adopt the most advanced digital technology to capture and compress video images, making it easier to store and transmit video images under the premise of ensuring image quality. Video images can be in the command center. Between the center and the center.
On the other hand, with the development of network technology and services, broadband networks are rapidly spreading to all corners of the city. In this case, the network million HD surveillance cameras can be easily applied without special wiring, and traditional surveillance. The equipment is much simpler and cheaper than the composition of the monitoring system. In addition, the network million HD surveillance camera has two-way transmission function, not only has all the functions of monitoring, but also can control all kinds of traffic management facilities on the road in the control room, such as switching traffic lights, warning lights, adjusting monitors, etc. Traditional equipment cannot match.
While providing monitoring means for the transportation system, the network million HD surveillance cameras can also provide road traffic conditions for the public. Drivers can decide which route to take based on the road conditions they see.
In terms of medical monitoring, the medical and health industry is one of the rapidly growing industries. With the economic development and social progress, people are paying more and more attention to the physical and mental health of individuals. The medical conditions of the entire society have been improved for the time and more relevant medical care has been generated. Equipment needs. In hospitals, many wards require regular patrols. This is a heavy manual work for health care workers. When patrolling in a ward, another patient in the ward calls the bell and cannot hear it. It is neither efficient nor possible. Mistakes. In each ward, a network of millions of high-definition surveillance cameras is installed. Each ward can be monitored at a doctor’s duty room at a glance. Various medical care and treatment are performed on the patient in a timely manner, which not only greatly reduces the labor intensity of the medical staff, but also ensures the emergency. Quick processing. When the patient's family members and friends cannot visit the hospital in person, they can learn about the hospitalization of the patient at a remote site so as to relieve their thoughts and concerns.
Community construction is an inevitable requirement for the coordinated development of urban economy and society. It is of great significance for promoting economic development, improving the quality of life of the people, and maintaining social stability. As China gradually enters an aging society, welfare institutions and community health care centers use remote monitoring equipment to greatly improve efficiency and service quality. The custodial equipment enables the widowed old people and the frail and sick and sick persons to get care and attention from the health care staff of the community health center at home. The children or relatives working outside can also see the situation in the home through the Internet and work at ease. With the progress of the Ethernet home project, the conditions for visualizing family health care are gradually maturing.
Workshop monitoring: High-quality monitoring equipment is required on the production line, which facilitates management and quality control of managers, and guides and resolves issues that arise in various aspects. Every process in the production process must be strictly controlled. There was a case in which a company took responsibility for the quality of the product, searched for unqualified parts, and dismantled all the products on the same day until unqualified parts were found. If network million HD surveillance cameras are installed at key locations in various processes, the playback function can be utilized, and it is possible to easily find the problem, save time and effort, and recover losses to the maximum.
Statistics show that many companies spend very high costs on after-sales services. If they install a network of millions of high-definition surveillance cameras, they can guide users through the network to solve many technical problems without having to send personnel to the site, in addition to saving a lot of labor costs and In addition to travel expenses, service costs are reduced, and the most experienced personnel can also provide the best technical support.
