    Hi there,

    I need to configure multi-cam live streaming gear with the small budget. Best if it would be possible to power it with batteries.
    Is there any alternative to Blackmagic ATEM Television Studio HD? If going with BMD Atem do I need anything else to stream it straight to the internet?

    Thanks for your help!

    Datavideo has a new system, 4 cameras with 3 of them as PTZ, record and stream locally if I remember correctly. https://www.datavideo.com/us/product/HS-1600T they quoted me about $12,000usd with three cameras but said they will have a new 20x camera out soon that would only be like $1,500usd each. I have some of their other products and they seem to be a decent company.

    They have some other systems if you want to use your own cameras.

    How many channels? A few of these could be used with a laptop: https://www.amazon.com/Magewell-HDMI...dp/B00I16VQOY/ (I added heat sinks to mine). A laptop going through a cellphone / hotspot / WiFi and you can live stream just about anywhere.

    I custom built a silent PC for live video work (though not portable) using this card (4 HDMI channels): https://www.amazon.com/Magewell-Capt...dp/B0178DV064/ . In a quiet studio the fan noise can be heard (ultra quiet PC), however it's not likely to be picked up if the mic isn't close by.

    You could build a small/light/low power PC and run off a battery such as this: https://www.amazon.com/LEDKINGDOMUS-...dp/B07FNLB4MS/ (haven't used, just an example).

    Here's pretty trick system which can run Windows 10 and Linux and has a PCIe slot for the 4 HDMI card: http://www.cappuccinopc.com/embedded...s-x16-slot.asp (has a PCIe x16 slot (only need an x4 for the capture card).
    Another one with a PCIe x4 slot (minimum needed for the capture card): https://www.spartonre.com/littlepcs/...lot-expansion/

    Some testing would be needed to find the right balance of CPU/GPU to handle 4 channels of 1080p and real-time compression for living streaming (I believe my iPhone X could easily do this lol, so modern low-power PC CPU/GPUs should be able to as well).

    Add OBS (free) https://obsproject.com/ and you've got a custom live streaming system which can do exactly what you want for relatively low cost and able to run off a battery.

    I would suggest using either a Convergent Design Apollo or an Atomos Sumo 19. Either can be used as a live switcher on battery power. You could then feed the output to an encoder box and stream via your laptop.
