Hi All,
Thanks to the good people who have advised on the first post. This
advice has been great on getting my mindset out of redmond and into
the reality of linux logic.
Firstly the Webshop software I was looking to run was Prestashop,
which I was glad to see, runs on linux. I have been ordering various
things from "Steam Age ecigarettes"and found this to be a great system
from a customer's point of view. However I was also advised that it is
not a good idea to run a webshop with a CCTV system. However, I would
believe that both applications require a maximum of security, as CCTV
cameras around a property could also be used very maliciously
(Especially if installed inside, which is great from a law enforcement
point of view).
It depends whether you publish the CCTV stuff, our your prestashop (
which really isn't my favourite eCommerce software ) on the net. Even
so, you can keep them completely separate and perfectly secure.
Regarding the hardware I currently have a conexiant 4 ch bt878 card
and a chinese thing with 4 philips DAC's which I was going to try just
to try for interest (It came with incomplete windows drivers and some
rather useless windows software which was all it would work with).
Once zoneminder is set up and running, I found some nice 4-ch PCI-x
cards on ebay, but unfortunately forget the name. with the existing
HW, the conexiant had only had 1 encoder chip, so the maximum
framerate was divided by 4 plus the overhead of the time taken to
switch inputs (Which is why I would intend to upgrade later). Reason
for not going for PCIE cards was that there are relatively few PCI-X
cards useful for a home environment.
Bt878 is pretty common, so you should have no problem with that.
The reason to use zoneminder was the usability of such a system. From
a CCTV point of view, having the thumbnails of things that have
happened are much better than trawling through lots of consistent
recordings. It's also possible to miss things in consistent
recordings. Other thing I like is the ability to define regions for
motion detection so that say if you have a camera over a footpath, you
can decide to either monitor the footpath, your own property or both.
The model of the server is (I think) MT-M7975-B2M. RAID card:
ATB-205/32MB. Hard disk appears to be hot swappable, and does say SAS
on the label. The connector is similar to a SATA drive. However I have
also seen drives labelled SAS with a D connector of some sort so a
little puzzled. It would be great to have this firmware thanks. If it
is not a completely mad idea, I would like to upgrade the RAID
controller later.
SAS drives are so expensive, and I don't really think it would be cost
effective... SSDs of a similar size and software RAID will out-perform
it, and you could well want a few TB so straight SATA would be a better
idea in my opinion.
Result from # dmidecode | grep "Product Name" was: IBM eServer x3400 -
[7975B2M] - M97IP
Yes, I'll admit this was quite a deafening machine when I first heard
it powered up, but once I installed Centos 7 the fans reduced to a
noise level which were comfortable enough to work beside it. Yes I am
in Christchurch thanks.
Pardon the sermon (Answering questions from the list and hopefully
returning some useful info). I do have one question though:
1. Fresh install of Centos 7, and log in under the default user
created with "Ädmin"privileges. Can't even save a text document on the
desktop or home directory (does create folders though). It sounded
like permissions, Is there something I can look up to learn why this
has happened (Say SElinux?).
echo 0 >/selinux/enforce
will temporarily disable to check further. IMO it's is terrible pile of
junk, written by people who don't understand base permissions, and I get
rid of it asap.
Thanks again very much for your support,
Peter Simmonds
