4K HDMI Video Encoder/Decoder, ZowieBox, UVC Converter, SRT/RTMP(S)/RTSP Encoder Decoder, Pass-Through Video Capture, HDMI Extender, Live Streaming to YouTube

Works pretty well, pass-through the HDMI, connect to network and you can share your a/v stream on network with only small delay. The admin website gives a number of options, but once you set it up for first time it's unlikely you'd come back. I did considered at some point the wireless HDMI adapters, but they seemed to be a bit unstable, while local network is rock solid. Note: I don't use 4K, just 1080p

So as i put in the title if you are using NDI as part of your workflow this little box is definitely worth having in your kit bag. The ability for it to encode or decode NDI comes in so useful in a number of cases. Most of our ptz cameras and laptops are all NDI enabled so we don't have to worry about converting from HDMI to ndi BUT there has been countless times where we've been on the job site and the client has wanted to use their laptop but the I.T department have had restrictions on installing software.... with this device it's no problem - we just plug in the laptop hdmi to it and away we go - it's there on the network as an ndi source. We've also had times where there have been other cameras in the room and we've been able to use them on our network but plugging them into one of these boxes to convert their output to ndi. It also works really well as a decoder - meaning our ndi output from vmix can be viewed on any screen with a hdmi input anywhere on the network. The build quality is also fantastic and its pretty indestructible with its metal casing and the screen on the front gives you all the info you need at a glance so you don't have to keep going into the settings to find out what it's setup for. Overall I've not found a better and more reliable ndi encoder or decoder anywhere near the same price point so cannot recommend it enough. We found them so good and useful we now have 4 of them in the kit bag!

Overall pretty pleased with this product. I wanted it for SRT use and that works well. NDI works well too. You can always question the video encoding quality on most products at this price point but on the whole I would recommend this for non professional use.

The item worked but couldn't service the purpose it was bought for. This may be due to the concrete structure of the building.

I was very excited to try this encoder as it seemed to be of excellent quality on the outside. The software looked promising at first, but I've found its usability to be not so great after using it for some time. There would be the occasional freeze, and sometimes the AV would be desynchronised. Most importantly, the audio ADC and the way it was controlled were not good. The sound would clip before reaching full volume on the stream, and it would be very difficult to adjust the levels to optimum levels when using the device. The available audio codecs were not of great quality too - there are a lot more quality options that are not CPU-heavy and can be integrated with this device in the future. There is no indication of the current input level on the web interface. I know Zowetek have been pushing software updates for this, and I would not be surprised if it gets better in the future, but I had to return mine.

I purchased one of these a few weeks back and have been impressed by the multiple options it has given me in the studio and remotely. So I bought another one. You need to read the full information as your uses might be different to mine. With 2 of these I can send and receive HDMI via Cat5e cable around the building. I can input into one and daisy chain it to the other and then RTMP stream to 4 different destinations. I can overlay graphics to the stream or add simple overlay text. I can control, power and output from non NDI PTZ cameras remotely. I can use a USB to seriel cable and control the PTZ. I can SRT, H264 and H265 all in 4K. I could set up a couple of remote cameras, log onto the local wi-fi and SRT/RTMP stream either to the studio or directly to Facebook and Youtube or more. I haven't been this impressed with a piece of studio equipment for a long time, but it really is the most useful piece of kit, especially if you are an NDI user in your network. Update: I have now purchased a third unit and aside from some confusion over how to log into the unit when using it in Hotspot mode (old manual with incorrect IP address in it) I have yet to find a downside to the unit. Currently I am connecting all my cameras into these boxes and powering them via a PoE router when mobile streaming with multiple cameras.

Just what I was looking for to stream games consoles into an Apple Vision Pro. Easy to setup, the only real gotcha was audio defaulting to line-in rather than HDMI. Simple to enable NDI/HX3. Good build quality, encoding crisp with no lag I could notice. Gets my 5* vote.

This has a lot of potential - but it is not a fully reliable box. The box is dumb and relies of the web interface to set up and run every aspect of this box. Unfortunately the web interface is very unintuitive and a real mess - with so many contradictory pages and buttons. This was designed by a poor IT engineer and ignores the way people will want to use this device in reality. The interface defaults back to Chinese a few times and does not inspire confidence it is working as it should. Would I trust this to record a stream? I am not sure i would. update: I have experienced a few box resets randomly. Also the video stream via NDI to HDMI is intermittent, dropping out sometimes or occasional jittery images. This makes it unreliable and so not usable in NDI mode. A real disappointment.

Hittils är den riktigt bra. Håller den i flra år är jag riktigt nöjd. Hittils har jag bara låtit dom stå på i några timmar utan problem. Hoppas det funkar bra i fortsättningen också 😊

Great product and quick delivery. Works as advertised.

This product was basically my first step into the complicated world of NDI, and I'm happy overall. This thing is a Swiss Army knife - it does just about everything, but not perfectly. BUT having a great quality 1080p real-time livestream of our camera feed, as long as you have a network connection to one of our campus network switches (which in turn powers the device with POE), is a game changer. Has no trouble displaying on 4K TVs and audio passthrough via HDMI works great. Makes for a super clean setup. Two gripes. This device has issues with frame rate conversions which might be solved in a future firmware update. For example, we run everything at 59.94 which the zowiebox detects as 60.00 (or at least that's the highest fps option in video settings, and no 59.94 option). Within a couple minutes there is a SEVERE delay to the audio channel. This effect appears to be caused by the Zowiebox "speeding up" the video channel to convert it from 59.94 to 60, but does not speed up the audio channel simultaneously, so for every second the audio gets behind the video channel by 0.06 seconds. So after 16.66 seconds the audio becomes 1 whole second behind the video, and after a minute it's approximately 3 seconds behind. The two options to solve this are to convert our video infrastructure to 60 (headache) instead of 59.94 which removes the conversion the Zowiebox is performing, or force the Zowiebox in video settings to 30fps. Somehow this fixed the audio issues and now everything is real-time. I've also had issues getting Multicast NDI to work properly which might be user error, but I've tinkered with this for many many hours. I have dreams of using our SDI-Zowiebox as our "transmitter" with a small army of HDMI-Zowieboxes as receivers for hallway TVs, classrooms and overflow rooms, and I'll need multicast with this. I'll have to tinker with this some more. Overall highly recommend. As I said, Swiss army pieces of hardware.

I've been using this device to stream RTSP feeds 24/7 from Blue Iris to my HDMI extenders, which display my surveillance video on various HDMI monitors around the house. So far, it's been working quite well. Setup was simple: I enabled decoder mode, entered the RTSP URL, set the RTSP feed as the primary stream, and connected the HDMI output to my extender. Within minutes, I had live video showing on my TVs. Performance has been stable so far, but I’ll update this review if I encounter any issues over time—especially regarding recovery from stream hiccups, which remains to be seen. Build quality is impressive. The unit feels solid and well-designed. You can tell some care went into the hardware. The Web UI is surprisingly polished—much better than I expected at this price point. It's clean, responsive, and easy to navigate. A few cons: It only supports a limited number of protocols (mostly RTSP). That’s fine for my needs, but something to be aware of. After a reboot, the stream takes about 30 seconds to buffer and appear. Not a dealbreaker, but worth mentioning. Overall, this device is doing exactly what I need it to do. If you're looking for a dedicated RTSP-to-HDMI solution, this one seems to fit the bill.

Le manuel explique les bases. Une fois sur l'interface web, il faut aller dans decodeur > uvc et activer la webcam. La page sera en erreur si la combinaison de paramètres est incorrect. Il faut donc savoir quelle combinaison la webcam autorise. Pour savoir ça, on branche la webcam au PC et on regarde les choix qui fonctionnent dans ses paramètres. Le boitier met du temps a démarrer, environ 20 à 30 secondes. Ça fait long quand on attend pour voir si ça fonctionne mais ce n'est pas dérangeant vu qu'on ne passe pas som temps à alumer et éteindre. Toutes les infos de base sont claires si on sait avec quoi on est en train de travailler. 5 étoiles car c'est intuitif.
