can supervise and manage the image informatization of paid jobs and provide creden。 for fraudulent behaviors. The monitoring software also displays images of multiple toll channels, toll booths, and important road sections at the same time, and records multiple images at the same time. However, based on my years of experience in cabling, I realized that with the extension of distance, the main character of traditional cabling-coaxial cable is increasingly unable to meet the needs of constructi

network cables for network cabling. They are divided into two types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines

A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into

Many people (including the author) think that 10 Base-T 10 m networks use four of the eight signal lines in the network cable, the 100 Base-t m uses all eight signal lines (or how fast ?). However, when the author recently used a 10 m direct connection method (switching between 1 and 3, 2 and 6, and shielding the other four lines) to connect the network cable, unexpectedly, it was found that the Network was being transmitted at a speed of MB, so I had to worry about it. So I checked a lot of inf

mainstream products. CAT6 and MB of bandwidth are CAT6, deploying a gigabit network is a future trend. Secondly, we can identify most of the five categories/more than five categories of false lines by looking at this approach. The characters printed on the real Category 5 online plastic foreskin are very clear and smooth, basically with no sertices. Fake handwriting printing quality is poor, Some fonts are not clear, and some are seriously jagged. Authentic cat5 lines are marked with cat5, and

phenomenon is this reason, because 3, 6 does not use the pairing line, in the short distance situation does not appear the problem, but once the distance becomes longer, the fault arises. All you need to do is RJ45 the head back in line, and everything will be back to normal. In addition, there are several twisted-pair manufacturers in order to better exceed the performance standards of

two types: shielded and unshielded. If it is used outdoors, The Screen Shield is better. Generally, it is enough to use non-shielded five-category cables in the room. Because no Screen Shield is provided, the cables are relatively soft, but their connection methods are the same. In general, there are four pairs of lines twisted together in the cat5e category and

change with the frequency. For the three and mixed five lines, the maximum NVP value of the line pair may be 12% different. In addition, the copper core wire in UTP is twisted, so its actual length is longer than the jacket of the outermost layer of the cable. For a 305 m cable, the core line may be 310 m. Based on the above reasons, the measurement result of th

How can network managers implement bandwidth-intensive applications on local area networks (LANs) when budgets are tight and must maintain existing network systems? The latest Ethernet technology, 1000BASE-T (Gigabit Ethernet on the five-type twisted pair) can help network administrators quickly improve the performance of your network in a simple and inexpensive way.1000BASE-T is an Ethernet technology that

recommended that 10 GbE be supported at least 5-100 m in cat6 cabling, and m in seven cabling. In addition, we are still investigating whether the shielded cat6 cabling and enhanced unshielded cat6 (sometimes called the E + class) can implement 10GbE within 100 meters. External crosstalk is still A major issue and the discussion is currently centered on A-NEXT, A-PSNEXT, A-FEXT and A-PSFEXT. The tia tr 42 committee in charge of cabling Affairs is dev
