    Dodgy POE switch??

     

    That thought did occur to me. The only item I purchased used was a midspan since my switch isn't PoE, but it's a high-end (albeit used) unit I got very cheaply; midspans seem to have no resale. However, that doesn't explain why each one locked up only once over the course of less than a week, unless it's simply coincidence.

    There's no such thing as coincidence in this game!

    So your using local mid spans to supply power, I doubt if it's the switch then but it's one less thing out of the chain, how about spikes on the local mid spans supply? Could cause a camera to lock up. Look for high current devices on the same circuit.

    I am fairly certain this is what Multicast is made to do, but I have very little experience with making it work.

    In what way have you had problems, normally if the viewing devices are in the same address range and are compatible protocol wise there should be no problems, ONVIF normally gives you a get out of jail free card when using NVR's of different manufactures although maybe some of the features like motion detection may not be available.

    I forgot to mention, the cameras will not be connected through to the existing network. They will have a closed connnection directly to the nvr. So no streaming via the network bandwith. I'm guess it's address will be 10.1.10.1 or something like that. The router is for networks and uses the 192.168.100.1 address. Will that be a problem, I'm afraid the nvrs won't see the camera because it will be broadcasted by the router with a different style of address. I have not committed to buying anything yet until I understand what I need to make it work this way, the nvr have separate port to connect to Ethernet. Mine will never be connected to it.

     

    So you will be using a POE NVR and the cameras will be plugged into that?

    Just put in a couple of the new 4mp cams. Both are exhibiting the same symptoms.

    As someone move across the scene, their image ghosts behind them, trailing the motion, not a smear from to long an exposure.

    The ghosted images slowly fade in about 4-6 frames. (running 4fps)

    The ghosting occurs on both streams.

    Almost like a compression algorithm glitch.

    When the scene is still, image crystal clear.

     

    I messed with various exposure and smoothing settings, no change.

     

    Anyone else have this problem with the new 4mp cams?

     

    For the record I have have several of the 3mp in play and working great.

     

    Any ideas?

     

    Is this viewed from the web browser or from an NVR?

    hello,

     

    First apoligies if i posted this question in the wrong section, my question is to do with router.

     

    i want to split the camera feed from one camera to two nvr's i was planning on using a Hikvision DS-7108N-SN/P nvr that has the port switches built in as the main recording unit. another 4 channel nvr DS-7104n will receive the second signal without recording it so that it can be viewed independently on another monitor. I dont fully understand how ip cameras work but my theory was to buy a standard 4 port router, plug the camera feed into the line in on the router, and the line outs can go to the nvr's? would that work? if so does the router have enough power on its own that i dont need an injector thrown in there? the cameras are also hikvision they have the cat5 plug and the power plug seperate. i would be using a poe splitter but does the line in on the router provide power to do that?

     

    lastly if someone has a better way to do what i want to do please share your thoughts any help would be appreciated. thank you

     

    Providing the NVR's are in the same address range as the Camera it'll work fine, most halfway decent IP cams can multi stream. You don't need another NVR to view the image either

    one of these

    will do the trick.
