Hikvision camera selection

I really appreciate all the support you are giving me.
I'm not familiar with this topic and something vendors make the stuff really difficult for the end user.

After all these information probably che M-series Is good enough for my needs.
I suppose also the price difference between the two models is relevant and saving money on the NVR give me the possibility to put them on the camera side

I will review then the camera selection, probably I'll share here some more doubt once I work on that

Thanks in the meantime
Really appreciated
 
Hello,
I've some more questions about the camera light.
In some model I see mentioned additional light like the one you suggested
Others have mentioned 4 light mode like the DS-2CD2343G2-LI(2U) or smart supplement light live the DS-2CD2346G2H-I(U)

Do you know which are the differences between them?

I'm just reflecting on the fact that because the camera will be in the farm could be useful having a camera with the light to better see what's happening if some notifications is raised

Thanks
Regards
