    Recommendation for 1 GB switcher? to work with NDI sources

    Hi,

    Read the techincal pdf on NewTek site.
    Out there - there are many models for different switchers.

    Can you please recommend of a 1 GB switcher model to buy?

    Thanks,
    Tomer

    Need more information to be able to recommend something for your needs.

    What is your networking experience?
    How many devices you to want to connect?
    Do you think you will be adding more devices in the near future?
    Need PoE or PoE+ support?
    If yes, how many PoE/PoE+ devices?
    Are you looking for a managed switch in case you need NDI multicast support or other network features (VLAN support, link aggregation, etc)?
    Do you want a switch that can be mounted in a rack?

    Hi Kane,

    Thank you for the quick reply.


    What is your networking experience?
    Have a good networking experience.

    How many devices you to want to connect?
    1-2 laptops
    3 PTZ Cameras
    1-3 spares one - for dynamic plan productions.
    1-2 HDMI cameras


    Do you think you will be adding more devices in the near future?
    Need PoE or PoE+ support?
    The only thing I know that PoE - is Power Over Ethernet
    Whats the part of the "support" - a separate electric power?


    If yes, how many PoE/PoE+ devices?
    Currently - 3 PoE PTZ cameras.


    Are you looking for a managed switch in case you need NDI multicast support or other network features (VLAN support, link aggregation, etc)?
    Currently, I don't think so. (need to verify that I understand the context of the above).



    Do you want a switch that can be mounted in a rack?
    Depend on the size of it.


    I wish there was also an option to have a switcher with SIM card option. (to have another source for LiveU).

    Thank you for the guided questions.

    I have the non-PoE version of the switch linked to below. This unit has a few management features, but is easy to setup. You can probably use it without any configuration, just how it comes out of the box. It has 16 ports so you would have enough room for everything you listed with some room to grow. It can be rack mounted or used as a desktop setup. Eight of the ports on the unit support PoE+ with a power budget of 110 watts.

    TP-Link SG1016PE

    While I do work for NewTek, so not take the above model as a endorsement from NewTek. It just happens that your network needs appear to match closely to the same model switch that I'm using.

    If you are looking for something a SIM card, you would also need a router.

    Hi Kane,

    Does the PTZ NDI cameras can connect directly to the switch - power over Ethernet?
    Meaning "Eight of the ports on the unit support PoE+ with a power budget of 110 watts." - will need to connect to those ports?

    Thanks again !

    If I can piggyback on this:

    I'm looking at connecting four true NDI cameras (not HX) to a TC460AE. A couple of other NDI sources (Scan Converter, VLC) will be connected to the same network, and the production will be streamed live.

    I was under the impression that a 10Gb managed L2 switch would be necessary in that configuration, which is needed for a church IMAG environment. (HX latency is not acceptable.)

    As a side note, I can't find any 10Gb copper switches with POE+, nor can I find any 10Gb POE+ injectors. I can power the cameras with AC if I have to, but it would be nice to have POE+ on the switch.

    Any ideas?

    I am not sure where you got the information that you need a 10gb switch to do 4 NDI inputs. A single gigabit line can handle 4 NDI streams.
    Our productions frequently use 12-14 live NDI streams and we are all on gigabit ports and switches. Granted our switches are all managed and all the traffic is in it's own VLan for stability purposes. We use the UNIFI series of switches from Ubiquity.

    I would suggest a 150w or better yet the 250watt version of the UNIFI switches. IF you do not plan on needing more of the power that the UNIFI line has with it's management then you could use the Edge series also.

    My math skills must be fading. Aren't NDI cameras 100Mb/s devices? If you are talking about 12-14 NDI|HX cameras (at 10Mb/s each) then the math works fine: 14 HX cameras x 10Mb - 140Mbs on a 1Gb switch.

    But 14 cameras x 100Mb/s = 1.4Gb/s, which obviously will not work on a 1Gb switch. Right?

    But if I read what you're saying correctly, 4 x 100Mb/s + other gigabit traffic (like a computer running scan converter) should work fine on a 1Gb switch. (Or does scan converter operate at 10Mb/s, regardless of the NIC speed?

    Sorry for all the questions, but I really need to pick the right switch, and I appreciate your help.

    NDI on a TriCaster is smart, depending on how it is used will vary the amount of bandwidth needed. If a source is on output, then it works just as you say, 100Mbit per channel for about 1080i video. However, if a source isn't on output, then a low bandwidth proxy will be sent which uses less bandwidth. This switching between proxy and high bandwidth is all automatic and instant.

    Beyond that a TriCaster 460 supports up to a maximum of 8 NDI inputs, so that system shouldn't overload a 1Gb interface even if all 8 NDI sources were on air at once.

    In answer to you other PoE question. The PoE standard is supported on 1Gb Ethernet, there isn't a PoE standard for 10Gb Ethernet.

    Thanks, Kane.

    That helps IMMENSELY.
