Hollyland Mars 400S [Official] Wireless SDI/HDMI Video Transmitter and Receiver for DSLR Camera, 400ft Long Range 0.1s Low Latency 1080P HD Video WIFI Transmission System

What’s can I say. The mars 400s works a treat. Simple, easy set up and easy to use.The build quality is unsurprisingly good for unit at this price.Images quality great too but you do get a little letterboxing. Nothing I didn’t expect though so no issue there.My setup is untraditional because I attach the transmitter to my MacBook Pro and use the Mars for remote screen for my clients to view live images from commercial photographic shoots. Its a very welcome solution for social distancing too due to covid19 restriction on set.To be honest for the price I’m a little blown away buy the build, quality and customer service from Hollyland.I can’t fault it so far.Jonny RoseDigiBoutique LTD

I be brief and to the point:Build quality 5/5Ease of Use: 5/5Transmission: 4.5/5Being in the filmmaking space this is a great unit as it is extremely well build, very portable with great features and solid performance with minimum lag! Whether you want to extend your display in a studio environment or put it on a 3-axis-gimbal these work a treat. Would love if there was a bundle that includes a set of batteries and short hdmi cables a quick amazon search solves this easily. Very easy to set up and get started so if you are on the market for a wireless unit this one should be on your list!

Just as important as the product is the company behind it. I bought my first pair of 400s and loved it so much bought a second pair. The second pair for some reason has a fault and just wouldn’t work consistently. Upon contacting the manufacturer and support staff they exemplified 5 star customer service they offered me a replacement and I was so impressed with their endeavours to help and resolve my issue so actually ended up upgrading to the cosmos 600 such was the support. The product speaks for itself but just as important as any product is the customer and after sales service and take it from someone who has had a lots of experience with IT products the support from Hollyland is the best I have ever experienced

Just bought my second Hollyland Mars 400s set! Already had one and it works perfectly. I use it on cinema / high end comercials where stability and reliability are mandatory and Mars 400s never failed me!!!I can have video feed on two monitores with 2x RX and simultaneously on Tablets and Smartphones thought WiFi video.Versatile Power input, can be done with NP-F..... battery or D-Tap cableSuper useful!!!!

Well built, very reliable so far and low latency from my tests with a monitor via HDMI and the app connected on an android phone.It's a nice upgrade from the previous model, with that WiFi option and the easy operation via the screens on the Tx and Rx...Time will tell but so far, so good. Excellent bit of kit especially for video shooters that need to work with multiple screens and even send shots over the internet via the app to somebody on the other side of the planet.

Surprised me in the reach it has, as well as good picture quality. Plug and play easy setup

When you take it out of the box, you can immediately feel that it is premium quality. The transmitting works great and you can even record wirelessly (up to 1080p). That said we are very happy with the functionalities.

This is amazing!
