Scalable Video (90 Channels) NVR

    Recommendation? Everything I am finding really quick maxes at 32 channels.
    I can tell the customer that scalability requires adding units I guess...

    Also, I am looking at bandwidth usage for MP+ IP cameras and the data load
    is staggering. I am thinking secondary network with a router connecting it
    to the primary network is necessary if you have more than a few cameras.

    The customer specified:

    6 cameras to start
    Equivalent of 2MP resolution view and record
    30 days minimum storage
    Scalable to maintain specs up to 90 channels.

    They did not specify IP or NVR, but I don't know any way to do it without
    going that way and sticking strictly with H.264 and keeping it down around 5
    frames. I am still limited to telling them to buy more NVRs for each 32
    channel block.

    Even with H.264 at 5 frames we are looking at 92.7 Mbps plus overhead by the
    time they meet full scale. If they demand higher frame rates on motion it
    goes through the roof.

    They already have an analog / dvr system in place Looked like a typical 16
    camera installation. Their goal is to use this new system to fill some
    holes and take care of immediate problem areas. Then to phase out the old
    system they have in place that they do not like, and then to add on to
    finish their needs. They already have a budget for the immediate project.

    In addition I have seen displays from two other facilities they have that
    have recently been upgraded similar systems. The amounts are such that they
    are required to go out to bid by law.

    I'm a Johnny come lately to the process just having been invited to the
    table, but I could use the business so I am going to chase it. They aren't
    yanking my chain. They are upgrading and filling holes in a progressive
    manner. Their real goal is about 90 cameras at this particular facility.
    The two smaller facilities that they did first looked to have 18 and 30
    cameras respectively based on the connection list I saw.

    May want to consider cloud storage like Amazon S3. That is going to be
    terabytes of data for 30 days storage.

    Looking at a minimum of 9 terabytes when fully expanded. Found a unit
    capable of 18 or 9 with raid. Available to start with 3 and all drives are
    hot swappable. Comes with 8 licenses and capable of 128. Set it up with
    its own switch and good to go. Can process upto 280 Mps internally so it
    can handle the load. Need to plan all 10/100/1000 hardware though.

    You can start with 3 drives? Is this a RAID5 array?

    What about backups and redundancy? Have you considered cloud storage at
    all? You could set the local head-end to keep only 24-48 hours on-site
    (dramatically reducing number of disks) and unlimited archives on a
    cloud server(s). You may find it's much cheaper and reliable to use a
    connected "Simple Storage Service".

    Standard Storage Reduced Redundancy Storage
    First 1 TB / month $0.125 per GB $0.093 per GB
    Next 49 TB / month $0.110 per GB $0.083 per GB
    Next 450 TB / month $0.095 per GB $0.073 per GB
    Next 500 TB / month $0.090 per GB $0.063 per GB
    Next 4000 TB / month $0.080 per GB $0.053 per GB
    Over 5000 TB / month $0.055 per GB $0.037 per GB

    License for what, users or cameras?
    Definitely. CAT6 or are you going to try with CAT5?

    3 Terrabytes. I was talking about terabytes.
    If the customer wants to stream off site that is their choice. They didn't
    ask for that, and seemed strongly adverse to adding to their recurring
    costs.

    Uh-huh. Like a simple stack connected to the SCSI port. Again... I am
    bidding this against other companies so up sells have to come later.
    Plus account fee.
    IP cameras. Users are unlimited.
    Have you actually looked up Cat 6? From what I have been able to find Cat 6
    is just Cat 5e which is certified to actually meet Cat 5e standards. There
    is actually a difference between 5 and 5e however.

    So, anyway... I have to meet the spec they provided which is not to
    redesign the spec and let the other bidders price off my work.

    Gotcha. You can call Pelco and they will build you a NAS solution to
    specs. I've put in some of their rack-mounted units that hold 18 drives
    (or 20, forgot) that are easily scalable as the project grows. The one
    at a certain federal facility has over a dozen of such HDD racks.

    You'll just need to keep an eye bandwidth as you know. I think you're
    right about keeping the CCTV network separate from their LAN, the IT
    department is only going to give you so much bandwidth if they want to
    bridge the two. Let them control their allotted cap to it's gateway,
    and roll your own network for the cameras. That will keep the IT guys
    from messing around with it hopefully. I would make sure to use a
    totally different color for the cables so it's clear to everyone which
    network is which.
