48 Cams @ 4MP TVI - 18 month storage!!

[EspLowVoltage 0]

I got a request to store 18 months of video in a large food processing place.

 

They currently have 48 analog cameras with (3) analog DVRs.

 

I've been asked to provide better resolution cameras, repurposing the existing Siamese cable.

 

So my solution is to go 4MP TVI with (3) Hikvision H265+ recorder. Using an external storage array or eSata, with at least 8 bays with 10TB per bay for a total of 80TB per DVR

 

Any other ideas ??

 

Some of my questions are:

 

Can I add more HDD as the time goes by, like one every 1 month or so?

 

Does eSata support H265+ ? (I'm sure it does because the DVR does the compression and just store it)

 

Is there a 48 TVI channel DVR that supports H265+ ?

 

Thanks!!

can you go to 2 dvrs it might make the cpu loads more reasonable.

I ended up using a Hik NVR 5MP with H.265+

 

with 2 internal 8TB and (4) eSata more.

 

monitoring the storage capacity to see it'll store all 18 months by calculating the average of every 10 days.
