Hollyland Mars 4K Wireless HDMI SDI & HDMI Wireless Video Transmission System 4K/30fps High-Speed Transmission 23.98/29.97/59.94fps Compatible 2-4 Flat Low Latency 150m Transmission Range 5G Wireless

バッテリーの持ちも良くて大変満足してます。 接続もスイッチonにするだけで簡単です。モニタリングで作業も効率よくなりました。

Hollyland Mars 400S PROに比べて全体的に安定感はあると感じました。 都内だと通信が時々途切れることもありますが大体はすぐに復帰します。

150mとありましたが、外で使う場合見通し距離で30m程離れると映像が途切れます。 電源を入れてすぐに立ち上がります。 モニターOUTと同時にスマホやタブレットのアプリでも見られるので、とても助かります。 映像信号が途切れると本体にNO VIDEOと表示されるのでわかりやすいです。 電波が弱くなると勝手にチャンネルを変更してくれるようです。 遅延は他のレビューにもある通り少ない方だと思います。 バッテリーの持ちは2時間程度でもインジケーターが2/3程度なのでまあまあ良いと思います。 ただし本体が熱を持ちます。

屋外で何度も使用しましたが、接続されても突然切断されチャンネルを検索して繋がってまたすぐに切断されます。原因をメーカーへ問い合わせましたが、対策はないようです。接続、切断を繰り返しても支障がない方はご購入ください。今から処分します

It works fine but transmission distance is not as advertised.

We needed to replace our previous Hollyland transmitter and thought we would give this a try. The picture quality and stability is amazing and the new stumpy style antennae’s made us feel that the didn’t have to handle it with kid gloves in the normal day to day shooting. Most of our shooting is run and gun and we can be in several locations in one day, so the conservative battery consumption means that one set of Sony NP70 batteries easily lasts the whole day. We had a few delivery issues but the one thing we can attest to is that the Hollyland customer service is best I have experienced from a technology company - they get back to when they say they will and are very solution orientated which is an important aspect of product purchase for us as a small production unit. We have already ordered two additional pairs to upgrade our kit and the whole team love them. Can’t wait to see what they bring out next.

Très bon achat et qualité pour ce produit. Se connecte directement.

I do Livestreaming and video production, brought this unit last week and I'm so thankful enough to have this in my hand for live stream wedding event that happen last week. Usually, my livestream is in line of sight for all my wireless transmitter and receiver, but last weekend we have to move from outdoor and indoor for the event. So, there were no room indoor to setup my system, we had to video switcher from outside close glass door, found out all my other transmitter couldn't get the video signal. I plug in the new 4k mars and it work perfectly fine without signal loss. from there I knew this was a keeper for my live video switcher. after get thing working. I have to move all my receiver to inside of the reception room for other camera to work. I use all kind of wireless video system and found this model is very fast when sync and pairing. The channel is very good it has the auto scan channel. I gave it 5 star Because it has a lot of improvement and quality to this model, 4k function for great cause I can now do cropping in my vmix switching during livestreaming. Wireless Signal and with New antenna are very stable for this price range compare to other video wireless company.

Hollyland has been making great strides in the last few years, becoming a good buy for pro video gear. It reminiscent of when Suny (now Sony) first hit the market and was distrusted at first. the 4k video transmitter does everything it says. I use it to stream from pro video cameras on shoots and it works very well. we have a 10k video system from a decade ago that doesn't work half as well. The latency of the video signal is minimal, not noticable for pro use. the distance LOS is very good. I did an outdoor event recently and used it in reverse to send signals from the video switcher to the projector which was hundreds of feet away. It worked perfectly. It finds its own channel and syncs by it self. you can manually change frequencies if need be. you will need to buy battery packs for it or another power supply as it only comes with one. I have sony f90 packs already so there was no issue. The units will run 5+ hours on a battery.

¡Hasta que al fin me los pude comprar! Funcionan excelentemente cuando estoy grabando. Envían la señal súper bien! Incluso puedo ver la imagen en mi celular. ¡Muy recomendados!
