Ungayikhetha njani iperi ejijekileyo I-I-Ethernet Cnakokwiprojekthi yokufaka ikhamera yokujonga ikhamera?

 

Nowadays, most of the installed network cameras still use the network cnako for transmission, and the most commonly used are the super five and six cnakos. If the 100M network we usually use the super five twisted pair, the gigabit network uses the sixizibini ezijijekileyo.

 

 

Here we talk about the national standard super five and six wire diameters, because the wire diameter of the network cnako is availnako 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 cnako.

 

Izinto ze I-I-Ethernet Cnako :

Izinto eziqhelekileyo kwintengiso: ingxubevange; i-aluminium ephezulu yokuqhuba; Isilivere yokuqhuba okuphezulu; ubhedu olunyulu; ubhedu olungena oxygen.

Ixabiso eliphantsi kakhulu le-alloy yintsimbi, kwaye umgangatho ngowona mbi 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 cnako 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.

Izinto ezinesilivere yokuqhuba kakuhle ikwayi-aluminium, kwaye umgangatho ungcono kune-aluminium enxibe ubhedu. Eli ligama, kwaye akukho silivere kwizinto eziphathekayo.

 

Umgangatho wobhedu ococekileyo ungcono kunalowo wealuminiyam, kodwa uxhathiso luselukhulu kakhulu.

Oxygen-free copper, also called red copper. At present, the best network cnako of the national standard, it is recommended that you choose this network cnako for monitoring.

 

Uyayazi indlela yokukhetha okanye yokuchonga imathiriyeli?

Ukongeza ekuthengeni uphawu olungcono ngexabiso eliphezulu, ukuba udibana nomrhwebi ongenabubele, kuya kufuneka uzivavanye ngokwakho. Indlela esetyenziswa ngokuqhelekileyo yokufumanisa ukulinganisa ukuxhathisa ngeemitha ezininzi.

A box of network cnakos 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 cnakos should be about 21-24 ohms.

 

The relinako transmission distance of the network cnako 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 cnako 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.
