The development of wireless technology to promote wireless products to the home users, by building a wireless network within the home, can let us anytime and anywhere through the installation of wireless network card notebook and desktop to enjoy the joy of wireless surfing. But for most of us, often in the use of wireless products on the existence of more or less misunderstanding, today we will introduce readers to the error of transmission distance,

From http://my.oschina.net/cmffire/blog/11290 Introduction: What is the basic function of the camera or video transmission? Video Transmission: It is to upload images one by one to the screen. Because of the fast transmission speed, you can see continuous and dynamic images, just like playing movies. Generally, when the number of frames transmitted rea

RS485 Bus I believe for everyone is not unfamiliar, I also used for many years, familiar with its circuit of the drawing, software program design methods, and accumulated a number of practical applications in engineering experience. But I always feel attached to the surface, "Why should I add a 120 ohms matching resistor?" "," where should the matching resistor be added? "," Why should I add bias resistors? "," How much of the bias resistor is appropriate "," how to properly pass EMC testing "an

The USB data transmission type isDescription from the perspective of USB system software management. Transmission refers to one or more bus transactions for information transmission between the customer's software and its functional modules. The transmission type depends on the data flow between the customer software a

Video Monitoring has six transmission modes: Video baseband transmission, optical fiber transmission, network transmission, microwave transmission, twisted pair balanced transmission, and broadband co-cable

Introduction:What is the basic function of the camera or video transmission? Video Transmission:It is to upload images one by one to the screen. Because of the fast transmission speed, you can see continuous and dynamic images, just like playing movies. Generally, when the number of frames transmitted reaches 24 frames per second, the image continuity occurs.Next we will introduce the whole process of Video

With the rapid development of video monitoring technology, the customer's requirements for video monitoring products are constantly increasing. The functional requirements are more complete and stable, and the performance requirements are clearer and more accurate. At the same time, how can we see a person's facial features in shopping malls, banks, and other important monitoring sites? How can we find out the license plate of a high-speed vehicle? How can we quickly and accurately find the targ

saving. Ethernet Ethernet Network: This is a local area network of online technology, but also the most widely used network protocol, it can through twisted-pair, optical fiber and other media to transmit digital data. LAN (Local area Network,lan, hereinafter referred to as the District network) refers to the small computer network in a certain area, such as in the Office, school classrooms and other environments. At present, most of the local area network architecture is in line with the IE

MTOM message optimization transmission mechanism is mainly used in the transmission of a large number of data, many articles also directly concluded that the use of MTOM file transfer efficiency. Why is mtom more efficient in data transmission than in other ways? is mtom really so perfect, what's the problem? When to use Mtom? These questions, this article WSE3.0

Differences between synchronous transmission and asynchronous transmission 2 recommended The difference between synchronous and asynchronous synchronization-that is, when you ask me to go to dinner, I will go to dinner with you when I hear it; if I don't hear it, you will not stop calling until I tell you to hear it, to eat together. Asynchronous-you call me and eat it yourself. After receiving the message,

The total amount of data transmitted or transmitted by a channel per unit of time is called the channel transmission volume. However, in actual application environments, all channels will suffer different losses, we call this loss a channel surplus. In our Integrated Wiring System, effective use of channel surplus can greatly improve network transmission performance. Based on the experimental results, the i

Real-time audio and video domain UDP is the king In the Internet, audio and video real-time interaction using the Transport Layer Scheme has TCP (such as: RTMP) and UDP (such as: RTP) two kinds. The TCP protocol can provide a relatively reliable guarantee for data transmission between two endpoints, which is achieved through a handshake mechanism. When the data is passed to the receiver, the receiver checks the correctness of the data. The sender can

Abstract: With the increasingly mature video compression technology, digital video monitoring products have gradually become the mainstream of the market. People Urgently hope that the network technology can be successfully applied to the field of digital video surveillance, so that people can achieve remote monitoring through the network. In this context, the study of "network-based digital video transmission" is becoming increasingly important. This

Digital Video SDI interface: Digital videos SDI interface: SDI interface is the first acronym for the serial interface of the numeral components (serial digital Interface), is by the SMPTE (Society of M Otion picture and television Engineers) a digital video interface standard developed by the organization. SMPTE is an international organization dedicated to the pro

June went to Shanghai to participate in the Dockone organization of the container assembly, reported a small project, accidentally won the first prize, here to share with you the core of the network of the building, is also the company has put into use the large file transfer mode .project Design :Original intention:1, as a provider of global cloud computing business, whether it is the expansion of its own overseas node business, platform expansion or customer custom template business needs, w

1. Work Summary Recently, the IEEE is working on a new project the project is to develop a standard for the operation of Gigabit Ethernet (10GbE) transmission based on the current copper structured cabling system, which is collaborating with leading experts from integrated wiring, electrical, test equipment and system design, Panduit belong to one of the leading ranks, we have foreseen that with the future increase in

1. Two modes of transmissionThe controller can be set to two modes of transmission (ASCII or RTU) in any one of the standard Modbus network communications. Users choose the desired mode, including serial communication parameters (baud rate, check mode, etc.), in the configuration of each controller, all devices on a Modbus network must choose the same transmission mode and serial port parameters.The selecte

With the advancement of optical communication technology, the access network has gradually evolved from a common analog user loop to an optical access network (OAN). On the other hand, due to the maturity and advancement of SDH technology, it has gradually changed from long-distance network to relay network, finally, it is widely used in access networks. 1 ). The transmission network is the platform of all business layers including the support layer,

Monitoring of overhead transmission lines supported by 3G/4G + Mesh combination The safe and stable operation of transmission lines is an important guarantee for national economy and livelihood. However, transmission lines have been affected by man-made damage, climate and geological changes, as well as illegal buildings, super-high-growth plants, birds, snakes,
