Nowadays, most of the installed network cameras still use the network cuyakwazi for transmission, and the most commonly used are the super five and six cuyakwazis. If the 100M network we usually use the super five twisted pair, the gigabit network uses the sixipheya elisontekile.
Here we talk about the national standard super five and six wire diameters, because the wire diameter of the network cuyakwazi is availuyakwazi in all kinds of markets, and there are many non-standard ones. The national standard super five wire diameter is 0.5, and the six national standard wire diameter is 0.56. In theory, the thicker the wire diameter, the longer the transmission distance. But the transmission distance is also closely related to the material of the network cuyakwazi.
Izinto ze I-I-Ethernet Cuyakwazi :
Izinto ezivamile emakethe: ingxubevange; i-aluminium ephezulu yokuqhuba; isiliva ephezulu yokuqhuba; ithusi elihlanzekile; ithusi elingena-oxygen.
Intengo ephansi kakhulu ye-alloy iyinsimbi, futhi ikhwalithi nayo yimbi kakhulu.
High-conductivity aluminum is commonly known as copper-clad aluminum, which is mainly aluminum, easy to oxidize, and the resistance will increase after oxidation. This is why the copper clad aluminum network cuyakwazi is used to install the monitoring, there is no problem when it is newly installed, and there will be occasional signal problems after a while.
Okuqukethwe kwesiliva eliphakeme kakhulu nakho kuyi-aluminium, futhi ikhwalithi ingcono kune-aluminium egqoke ithusi. Leli yigama, futhi akukho siliva kokuqukethwe.
Ikhwalithi yethusi emsulwa ingcono kuneye-aluminium, kepha ukumelana kusesekukhulu kakhulu.
Oxygen-free copper, also called red copper. At present, the best network cuyakwazi of the national standard, it is recommended that you choose this network cuyakwazi for monitoring.
Uyazi ukuthi ungakhetha kanjani noma ukhombe okubalulekile?
Ngaphezu kokuthenga umkhiqizo ongcono ngentengo ephezulu, uma uhlangana nomthengisi ongenamusa, kufanele uzihlole wena. Indlela esetshenziswa kakhulu yokuthola ukukala ukumelana nemitha eningi.
A box of network cuyakwazis is normally 300 meters (in fact, it should be about 305), the resistance of the whole box is tested, the resistance value of the super five should be 27-30 ohms, and the six types of cuyakwazis should be about 21-24 ohms.
The reliuyakwazi transmission distance of the network cuyakwazi is about 100 meters. Do not hear on the Internet that others transmit 120 meters, 150 meters is no problem. The transmission distance of the signal on the network cuyakwazi will be attenuated and data packets will be lost. There may be an image after 100 meters, but there will be problems in the future and maintenance will be very troublesome.
