Megapixel IP Cam Installations



  • I have some Arecont AV5155DN -5 Megapixel cameras which pull a good bit of bandwidth i noticed. I was wondering if anyone has worked with large arrays of cameras or even "Machine Vision" megapixel cameras and PfSense? Since they are so bandwidth intensive i am tempted to physically separate them into their own dedicated network. Anybody give some real world numbers on IP cameras and networks. They sell some "surround video" cameras which tie 4 ea. 5 megapixel cameras into one ethernet cable. Anyone running multiples of these?? 20 megapixels per camera is alot…Now i see a newer 40MP Version..

  • You can't address them individually?

    I have a few scattered here and there and access them via vpn.  1 IP gets 1 camera for me.

    Or you can attach them to a computer that manages them and uses software to compress and stream the images to reduce the bandwidth.

    There is no video compression with your cams?

    That cam supports:

    H.264 (MPEG4, Part 10)
    Motion JPEG

    I'd go with H.264



  • Yes you can separate the streams. The point being they are now cramming 4 cams down one pipe, albeit Gig-e and that is newer development. Plus 40 megapixels -here&now- we are talking alot of bandwidth? Is Gig-E routing enough. I see the dramatically lower framerates on the 40MP so maybe same dataflow just bigger frame…

    Was wondering about the motion sensing and capture features. In the past i worked with Avermedia NV6xxx and even with the death of analog cameras their software adapted to ethernet inputs and their software was well refined and they have nice I/O standard issue.

    Fast-forward and now we have camera software AV200 that is free from Arecont and usable without the frills.... Is there anything else out there descent and not expensive?? I have used Blue Iris and it works great. Would like to separate from Windows soon. XP is dying. Zoneminder has been on my working wish list but every time i try it it is lacking and un-intuitive.

    Hope this is not stray off the pfSense topic too much.



  • Its going to depend on your frame rate and compression settings.

    It would be nice if the built in firmware would let you input a simple max bandwidth and adjust the compression and loss accordingly.



  • I have some small scale installations and i know i am really surprised how hot the single cameras get. I actually have been building custom enclosures for the AV5115DN and it gets so hot i can't believe many electronics could last long at that temp. I have had one go faulty -so i dove inside. Turns out the Day/Night motion wheel thing in front off image sensor had a wire pinched underneath a heatsink. Not good sign for made in the usa. The engineering inside looked solid and rugged. Thinking of running one without body to let it breathe. They look great image-wise. All the old analog lenses now have new lease on life.



  • And how about the Synology solution.
    Put the camera stuff right on the NAS.

  • Was even thinking this might be a good way to use visualization.

    Currently:
    Need Windows box for motion software capture AV200 or BlueIris
    FreeNAS/Nas4free box for storage
    pfSense routed network.

    Maybe install multiple -4 port Gig-E POE cards with FreeNAS and Windows visualized…Areconts cameras directly attached. No real routing needed? Windows would assign IP's and NAS is ISCSI or should i consider third virtual machine with pfSense?
    Keep the cameras at max POE cable length i know.

    Sound feasible? Worthy approach?

    I leaning twords Xen? Good or bad?
    Not a lot of custom hardware that need passing thru so should be OK?

    Thanks for your help



  • Could bite my tongue and buy Windows Storage Server and avoid the NAS altogether. Can Windows Storage Server networking hold up OK with 12 gig-e streams at full load. That is the question…..Blue Iris can holdup but in need of LOTS of help CPU wise. I haven't stress tested AV200 yet.



  • I'm not sure about those cameras or how many you can stream or processor required.  I never stream more than 1 at a time due to bandwidth constraints.  Mine are not open to public so when I'm not logged into one, its not burning bandwidth.  The way I do it, I could support as many cams as I like on a little bandwidth.
