I have been doing a lot of research trying to understand many variables regarding VMS that run on servers and I'm wondering how do we make a decision of what to buy when we are not computer genius.
The thing is I don't trust (not in a bad way) what I'm been told by the software company and the hardware company because I do not seems to be able to get answers to my questions. English is not my first language so my vocabulary is limited and that is frustrating.
I want to use Axxon Soft as a VMS on servers build from BCDVideo.
The thing is BCDVideo asks questions regarding the bandwidth since they guarantee their calculation on TB needed and Axxon asks questions regarding what you gonna do so you have enough CPU. Like many clients mine do not know yet but want something.
ME, I want to know how many cameras a server can handle, and what is the limitation of the physical constraints?
I understand that depends on many factors... but I don't want to go deep. Just enough to make a basic decision on what i'm been sold as a client.
But my little experience is that so far:
I have (2) server build by another company and depending on what I throw at it in the camera config it is rushing or working ok for 56 cameras. After many calls with tech support, they make it work by modifying all cameras with the lower settings... Not what my client wanted.
I have (2) servers build by BCDVideo where I jack the setting of 126 camera per servers many 2MP, several 8MP, some 4MP at 16Fps with high quality and it seems to purr happy but the VMS (software) not so much.
Since it is the fault to no one, what should I look for when I will buy my (fifth) server?
Some are telling me that windows can not handle more than (x) Mbs so why do we have GIG Nic?
Some are telling me that there is a limitation of what the hard drive can handle. Ok, so what is the limitation?
Some are saying it is because the database (metadata) should be on a separate disk that is an SSD. So does that will really make a noticeable difference in VMS MetaData security world? Some say yes, some say no.
Have been told to buy a few smaller dedicated servers and run a NAS that will receive all camera recording and the NAS will handle all the data and Bandwith that you will throw at it (trueNAS)...
Some are saying you can put more cameras but upgrade your CPU from 4210 to 4216 and even better get a Xeon gold ... OK but why? 126 camera CPU is 30% load with silver 4210 Xeon...
Gee guys I'm lost and I wan to hit my head on the wall. Why it is so complicated ...
If you will ask me some number, then just for fun use 140 cameras at 3MP at 16 FPS best quality 50% recording, 1 Keyframe per 16 frames. Change it if you want.
My client wants quality. No restriction. The bandwidth is not a limitation where I'm. So I can push the system as much as I want and I found that there is a lot of fragile link in the chain.
