Carane PoE injector sumber daya lan jaringan kanggo kamera

The early development and later construction of the PoE injector supply scheme for security monitoring equipment are closely linked. Especially in the later construction stage, the specifications, characteristics and related protocols of PoE cameras and PoE power supply modules must be fully understood.Only in this way can we ensure that the monitoring project is completed efficiently and at low cost. How does the PoE power supply module power the surveillance camera and provide the network?

Sumber daya PoE mbutuhake mung siji kabel jaringan kanggo nyedhiyakake daya lan transmisi jaringan menyang AP (kamera PoE, AP nirkabel lan peralatan liyane) bebarengan. Sistem ngawasi keamanan nganggo solusi sumber daya PoE jaringan (deleng gambar ing ngisor iki kanggo rincian), ngilangi kabutuhan instalasi soket lan panyebaran kabel listrik. etc., mangkono ngirit biaya wektu, biaya penyebaran jaringan, biaya pegawe instalasi, lan biaya pangopènan mengko, etc.. Sing liyane PoE injector sumber powered piranti digunakake ing jaringan, luwih ketok iki wektu lan kauntungan biaya dadi.

Mung ana telung standar kanggo modul suplai injektor PoE. Daya sumber daya IEEE802.3af yaiku 15.4W / ing. Daya sumber daya yaiku 30W/bt. Daya sumber daya yaiku 90w (deleng gambar ing ngisor iki kanggo rincian). Kepiye cara cocog sumber daya PoE lan panrima daya PoE (kamera PoE)? Contone:

1. Nalika daya kamera PoE 10W, sampeyan bisa milih modul sumber daya IEEE802.3af PoE;

2. Nalika daya kamera PoE 20W, sampeyan kudu milih modul sumber daya IEEE802.3802.3at PoE;

3.It should be noted that the 802.3at standard is backward compatible with the 802.3af standard, so when the PoE camera is 802.3af standard, you can choose an 802.3af or at standard PoE power supply module.

Standar 802.3bt kompatibel karo 802.3at lan 802.3af.
