  • Perfect next step for you kit
Size: TX&RX
Coming from the 400s to the 400s PRO II has been a seamless, pain-free process. I am a fan of the 400s Pro II! Particularly the exceptional build quality and versatile power options offered. While minimal delay could potentially pose a challenge for live broadcasts or pulling focus, it's inconsequential for my purposes as a Gaffer. I would highly recommended for its outstanding performance and flexible power choices. The seamless ecosystem integration enhances user experience, delivering top-notch video quality with minimal latency. The system is not only customizable but also offers great value, proving accurate ranges and excellent indoor performance. A perfect addition to your kit if you are already in the hollyland ecosystem, or a great place to dip you toes and start your experience. ... show more

  • Sync Fast Enough for Live Productions - Great Image Quality
Size: TX&RX
The media could not be loaded. This is actually my 4th set of Hollyland transmitters (I own a pair of 300s, The Mars M1 Enhanced Monitor, The original 400s and now 400s Pro II). The fact that the whole eco-system works so well with eachother is a huge plus. Depending on the requirements, I have found that each of these has a usecase and the flexiblity is very welcomed. I sold my 400s Pro Is mostly because I thought the quality output vs the 300s wasn't a big enough difference to keep. Enter the 400s Version II. With previous transmitters I struggled with audio and video syncing for talking head situations such as podcasts. There are plenty of tools in my audio and video mixer to correct this, but the lower latency the more I could trust my hardware in providing a usable audio/video sync in certain situations. I can say that both the video quality and latency work very well! This has made my podcasting and recording environments much easier and convenient to work in. It does what it says on the tin and does it very well so I am very happy with these units. Definitely keeping these unlike the version Is. If I needed 4k for my workflow I might spend the extra money for the 4k transmitters, but haven't needed them yet. ... show more

  • Very Nice Product !
I'm going to tell you about the new Hollyland Mars 400S PRO HDMI and SDI Wireless Video Transmitters! So the Mars 400S Pro SDI & HDMI is fine, but what is it for? The Mars 400S Pro are intended to transmit video wirelessly from a camera or other video sources to a receiver (Screen, Atem Mini Pro, video projector, etc.) with a distance of up to 120 m and powered by a SONY NPF type battery and video resolution up to 1080p in 60 frames per second. So yes the Design is totally different from the other versions of the Hollyland wireless video transmitters. Like it or not, personally I like its shape and the fact that its center of gravity is lower thanks to the cold shoe placed below the transmitter for a faster and more stable installation in my opinion of course. After each one will form their opinion on it. In terms of construction, we feel a very solid and well finished product. Which is reassuring when you're a professional. At the transmitter level the color code used is red and blue for the receiver! Very practical when you are in the rush of an installation on a shoot or on a livestream. The screen on the front also allows you to quickly read the necessary information. I still find that a percentage indicator is missing from this screen. Even though I have noticed with “ATOMOS NP-F750 5200mAH” batteries a battery life of over 8 hours, which is more than enough for filming or live! On the box we find a USB-C port which can be used to charge boxes, but also with a usb-c to RJ45 adapter to be used as VIDEO STREAM! A very practical ON / OFF BUTTON but I would also have preferred a button with a long press to turn off or turn on the March 400s pro for more security. And of course the SDI and HDMI connector as well as the location of the battery and the two antennas. The practicality of having SDI on the box, for example in my case, I used the transmitter connected in SDI on the panasonic EVA-1 camera and the receiver connected in HDMI on the matem mini pro ISO. And you can use it inversely in both directions, that is to say connected the transmitter in HDMI and receive with the receiver in HDMI. I have had the product for a few weeks and have used it on a few LiveStreaming and filming. On the other hand, I highly recommend it for LiveStream, for example in my case I use 3 Mars 400S Pro + 1 Mars 300 Pro, and it matches up very well in terms of image delay. (About 5-6 Frames of latency) On the other hand, the good news is that the flow rate has been increased on this version, we go from 8 Mbps to 12 Mbps which is not negligible in terms of quality, especially when using Livestream. Hope you enjoyed this review of the Mars 400S Pro. Ciao! ... show more

  • No more cables it a good thing.
Eliminating cables running along the ground from video cameras to our switchers was a top priority in my church. It seemed like every service somebody would trip over a cable causing us to lose our video signal from a camera until reconnected. It is nice not having to run cables any longer. We have 3 of these and I think that is the most you can run together. Maybe 4. 3 is all my church needed though. They are extremely easy to set up, durable, and take less than 10 minutes to learn to use. Well worth the money. ... show more

  • Please clearly specify supported batteries
This works really well, but please specify which batteries are supported. The answers to all of the questions say "standard NPF Sony batteries". So I bought Sony NPFZ100 BUT despite it having NPF in its model name, it does NOT fit. It is smaller than most other NPF batteries. Unfortunately for me, since I bought the batteries at Best Buy, I can't it since they don't accept returns on batteries. Another thing I noticed that if you are not supplying the unit without enough power (i.e. plugging it into a USB power bank that is too weak), you will hear the unit start to make a squeaking sound and it also may just shut off on its own. Other than that, this thing is really solid and is really just plug and play. I tested having the receiver inside the house and then walked outside at the backyard with the doors closed and there weren't any hiccups at all. ... show more

  • Build quality is top notch
Size: TX&RX
Very impressed with Hollyland so far. I also bought the M1 enhanced monitor. We’re using this for the directors and 1st Ac monitor. Build quality is top notch. It’s able to take multiple power sources which is a huge plus. It was cheaper for me to buy this than to rent a teradek system and I am not disappointed. There is about a frame or two of delay which I could see being a problem for someone doing live broadcast but for pulling focus it’s a non issue. Highly recommend. ... show more
