    Larger system unstable - where's the issue?

    Almost - the site is subject to regular 'move arounds' that would affect camera locations, but I can probably find 3 or 4 things 'big enough they wont move'. My advice is going to be simply that they need to hardwire the lot and deal with any moves later on!

    Larger system unstable - where's the issue?

    This is really useful to get some idea of likely limits - many thanks!

    100% agreed on that much.

    Larger system unstable - where's the issue?

    You are wrong, for the reasons stated, but I'm not going to get into a debate here. Maybe read up on 802.11 protocols and specifically TDMA to see how it works. "video is a very wide signal" is nonsense in the context of a digital stream (its just 1s and 0s) and nothing 'overlaps'.

    Larger system unstable - where's the issue?

    Thanks for the reply, but you are confusing analogue video transmission with wifi (which is what we have here). Wifi is a TDMA (time division) protocol with the concept of time slots - so things don't get overrun ever at an RF level and many hundreds of (idle) clients can be accommodated by the...

    Larger system unstable - where's the issue?

    It's just 802.11n so yes, theoretically 300Mbit, but in reality, a fraction of that especially if a slow client is dragging it down. The solution I think here is clearly cabling it, I'm just bemused by the exact symptoms I'm seeing. I'm fairly sure the idle stations are indeed idle as the AP...

    Larger system unstable - where's the issue?

    I agree that the bandwidth is probably overwhelmed but not "too many transmitters" - this is wifi, you can get lots of devices to play nicely, albeit at slower data rates!

    Larger system unstable - where's the issue?

    That was my conclusion. What confused me was the inability to see the UI of the cameras via their IPs before they were adopted to the NVR ie when no traffic was passing. Maybe I need to be a bit more methodical and retest that. Are we saying that reducing to 1080P, say 10fps, might get it...

    Larger system unstable - where's the issue?

    I have been asked to 'look at' a newly installed system that will not work reliably. It consists of 12 (Uniview) wireless 4Mpixel cameras, talking back to a single 2.4G (Engenius) Access point, then onwards to a Uniview NVR. The network has a BT Hub as the router and an onward FTTC Internet...

    Sourcing Huisun

    Is there a 'best place' to be buying these? Either China direct or elsewhere (I'm in UK). Happy to wait for them. Any names to be Googling or Aliexpressing?

    Off site DVR backup question?

    To shift 500Gbytes, from 6 locations, every 3 (say) days I make that a Internet (/IP) connection that has around 11Mbit upload at each site and 70ish Mbit download at the central site, all running 24/7 with no slow downs or outages. Doesnt looks economical to me! Bigger HDs at each remote...

    'Reality TV' style recording on a DVR extracted to video edit

    Help, critique or advice very much welcomed on the following slightly unusual scenario. I have a relatively low budget requirement to record lots of sports events - lets for simplicity call them 100m sprint races. There is money for cameras and a recording system, but not for lots of staff...
