"Encoding Channel" in SADP tool

[IL-MAFIOSO]

Good evening,

I'm looking for informations for what's is "Encoding Channel" we can see in SADP Tool.
I've five cameras connected to a switch POE to my NAS.
In SADP Tool, i have cameras with 0 in "Encoding Channel" and 1 on other.

Is someone can explain what is "Encoding Channel", what is the difference between 0 and 1
And the consequence in the use ...
Should i change some values regarding my settings ? And then where this change can be done

Thanks for your help

Hi, I bought 3 years ago, in Spain, a NVR DS-7608NI-SE / P with version V2.3.7build 131112 and 3 cameras DS-2CD2632F-IS with version V5.1.2build 140116, cameras with SADPTool has Encoding Channel (s) = 1. They work perfectly.
1 month ago buy, in Aliexpress-China a DS-2CD2632F-IS camera with version V5.4.24build 170303 activates it with SADPTool and has Encoding Channel (s) = 0.
The new camera (V5.4.24build 170303) is not detected by the NVR. What solution can you offer me ?. Should I update the NVR firmware? Thank you.

Hola, me compre hace 3 años, en España, un NVR DS-7608NI-SE/P con la versión V2.3.7build 131112 y 3 cámaras DS-2CD2632F-IS con la versión V5.1.2build 140116, las cámaras con el SADPTool tiene Encoding Channel(s)=1. Funcionan perfectamente.

Hace 1 mes compre, en Aliexpress-China una cámara DS-2CD2632F-IS con la versión V5.4.24build 170303 la active con el SADPTool y tiene Encoding Channel(s)=0.

La cámara nueva (V5.4.24build 170303) no la detecta el NVR. ¿Qué solución me puede ofrecer?. ¿Debería actualizar el firmware del NVR? Gracias
