Hollyland Mars 400 Overview

The Mars 400S from Hollyland is an entry-level 1080p60 transmitter/receiver system featuring a 400' line-of-sight transmission range. In a compact design, the transmitter and receiver each have an SDI and HDMI connection. The choice between the two connection types expands your compatibility options and also lets you grow in case currently you only need one.

Additionally, an optional second receiver can be linked up to the transmitter to accept the signal at the same time. The transmitter is also capable of sending the signal over built-in Wi-Fi to up to four mobile devices, whether it is also sending to a receiver at the time or not. This will allow different people/departments on the set to view the image being captured. The image is sent to the HollyView app, which is compatible with iOS and Android.

Both the transmitter and receiver have a built-in L-series battery plate and also support DC power. Batteries are sold separately. One power adapter is included to get you started on the receiver end. Both units also have an OLED display that confirms the resolution, transmission channel, signal strength, and other details. The display also shows a low battery warning when there are about 30 minutes of runtime left.

One of the features of the Mars 400 system is a channel scan function. Via the OLED display, you can see the status of each selectable transmission channel in the environment you're in. This feature lets you know which channels are good and which have interference. Another feature is scene mode selection, which allows you to select from three different scene modes as best suits your environment. The three modes let you prioritize between video quality, low latency, or a balance between the two.

The transmitter and receiver are each approximately 4.5 x 2.5" and have a robust yet lightweight metal housing.

can these be used for live streaming? Will latency be an issue?
Asked by: Frank
I feel that latency is not an issue, but anytime youre dealing with wireless transmission and then sending that signal into a switcher, there will be latency to be aware of... but depending on your project (how strict sync needs to be from all feeds), it will likely not be a deal breaker.

I'm somewhat confused. The website lists a 400S Pro that is less expensive (except this week the 400S is on sale) than the 400S which, in its description says it's entry level. What is the difference?
Asked by: Mark
The 400S and 400S Pro are very similar. The Pro adds a USB C for power, monitoring via the app, and multiple fan modes for those who need absolute silence. It is designed to be more streamlined and sit better on a camera via the hotshoe adapter.
