3G SDI IP Video Streaming Encoder Decoder, ZowieBox, SRT RTMP RTMPS RTSP, UVC to SDI, SDI Video Capture Extender with Loopout, Standalone H.265/H.264 Live Streaming with PoE

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.

Encode and decode both work while powered by POE. Interface is fairly straightforward, and has a couple of features that were not on my “must haves” but are handy regardless (like disabling Tally lights, and the gui on the unit) I have only tested on a fast and simple network but everything worked well.

I'm using this item connected to a Sony ZV1 camera for the purpose of transmitting video over NDI wirelessly to OBS studio then to Twitch stream. The product works well and provides a lot of control over video and audio quality. It is a fairly economical way to do so, considering you typically have to pay $99 just for an NDI license for each product you use, and that fee is included in the $150 price. The quality is good, and I'm hoping in the future they will support even faster transmission rates at higher resolutions over wireless NDI. NDI requires a lot of bandwidth, so a strong wifi is required. I'm only taking one star off, because I feel like the transmitter could be stronger, especially considering the antenna is inside a metal box, which isn't a great location for an antenna. It makes the unit streamline, which is nice, but reduces effectiveness a bit. I think they should consider adding an external antenna port, which would help improve the distance covered. The only other negative was the unit seems to be a bit sensitive to swapping wifi network. I was on one wifi, then switched to another, and when I did this, the unit started acting very erratic. I was getting choppy video and couldn't figure out why. I had to do a factory reset to fix the issue. Also, I run a pretty mobile setup, and it didn't seem to like being handed off from one wifi access point to another. It would lock up during the handoff and I would have to restart the system. Pretty good technical support, other than having to wait a day since I think the support team, for me, is overseas and on a different time zone. Overall a good product, and I'd recommend, but I could see them making a few tweaks to improve even further.

Quite amazing how much this little guy can do at the price point it's at - can encode OR decode, stream, record, utilize NDI, PTZ and tally controls, there's so much flexibility it's a must have. The IP gui is fairly intuitive and there's even a live preview with controls. Even came with a shoe mount. I mainly wanted some hardware that could serve as backup records, and this does just that. Only thing I don't like is you must split your recording either by time (45min max) or file size (4GB max), and it may introduce some freeze frame in the last few seconds if you're trying to string them back together. Otherwise, perfect for a backup and a general webcast/video multi tool!

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.

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.

Der Encoder funktioniert besser als erwartet (vergleichen kann ich mit einem eigenen Prototypen, dem Kiloview und TP Link, die alle ein Vielfaches kosten und nicht so viel leisten). Allerdings ist die WLAN Verbindung als Access Point oder Client nur zur Konfiguration geeignet. Der NDI Stream der ZowieBox wird, warum auch immer, nur über die LAN Schnittstelle ausgegeben. Ist aber auch kein Problem, an den LAN Port einen mobilen Router anzuhängen. Der NDI-HX Stream wird ohne Probleme von OBS unter MacOS erkannt, ebenso unter Windows, nur leider nicht unter Ubuntu, obwohl dort OBS 27 + libndi 4.5.1 + obs-ndi 4.9.1 andere NDI Streams anzeigen kann. Die USB C Schnittstelle braucht 5V/ ca 10 (max 25) Watt, die Stromversorgung über Powerbank oder PoE ist damit möglich und läuft stabil. Strom Versorgung eines weiteren Gerätes ist allerdings etwas mickrig und reichte bei mir nicht um zB eine DSLR auch beim Fokussieren mit Strom zu versorgen. Auch als Decoder funktioniert die Box ohne Probleme. Allerdings erkennt sie dabei nicht full NDI, sondern nur NDI-HX. Kann also schwierig werden, wenn der Zuspieler nur full NDI produziert. Nachtrag 7.3.2024: Die neueste Firmware kann nun auch den NDI Stream über WLAN ausgeben, das war mein einziges Manko. Das Tally Light funktioniert einwandfrei, Geräuschentwicklung ist gering, läuft stabil auch im Dauertest, damit 5 von 5 Sternen. Nachtrag 6.4.2025: Ziemlich bald kam noch eine weitere Zowiebox für eine weitere Kamera dazu. Es gibt regelmässige Firmware Updates, einen aktiven Email Support und seit letzter Woche geht nun auch noch der UVC Signal Import, dh man kann auch DJI Kameras o.ä. anschliessen.
