Hollyland Mars 300 PRO is a budget wireless transmission system with HDMI Loop-out, multiple power options, and real-time monitoring from smartphones.

No strangers to budget wireless monitoring systems, Hollyland is bringing yet another affordable wireless system to content creators and videographers.

Furthermore, due to its HDMI connectivity, the Mars 300 PRO is naturally geared towards those using mirrorless hybrid or DSLR cameras. In addition, the Mars 300 PRO is also compatible with the Hollyview app, which allows users to send a wireless video feed to up to 3 smartphones or tablets. 

HDMI Loop-Out 

Available in three versions – Standard, Enhanced, and Solo, the Mars 300 PRO is suitable for just about any budget.

Priced at just $199 USD, with the Solo version you get the Mars 300 PRO HDMI TX, which allows you to transmit a real-time video feed to a smart devices at distances of up to 300 feet line of sight. And this will be more then enough for the average video user producing (most likely) content for the web. 

Moving on up to the Standard set (TX and RX for $449) you get the two units pictured below, with built-in antennas. The Mars Pro 300 HDMI is good for sending a 1080p video signal with minimal latency (rated by the manufacturer at 0.08ms) to monitors or smartphones/tables up to 300ft line of sight.

The Mars 300 PRO RX has 2 x HDMI outputs giving you more flexibility to send a signal to up to 2 monitors on set. 

Side OLED Screen for Better Users Experience

The Mars 300 PRO transmitter has HDMI in and out with a loop-out function, meaning you can also feed a video signal to your external monitor attached to your camera at the same time. This ensures compatibility with basically every HDMI monitor out there. In addition, the OLED side screen paired with a scroll wheel allows for easy navigation through the menu options. 

Enhanced Version with Detachable Antennas 

The Mars PRO 300 Enhanced (get it on Amazon) gives you two additional detachable antennas for improved transmission in noisy Wi-Fi environments, where the built-in antennas may struggle. Otherwise, these are the same units as in the Standard version.

Real-time Monitoring from Smartphones and Tablets

Just like the more affordable entry-level Mars X system, the Mars Pro 300 can send a wireless video feed to smartphones and tablets running the Hollyview app. Users can send a 1080/60p signal to one receiver at a time and up to 3 smart devices. 

This is a fantastic feature for cost-effective wireless solution to give to clients, directors or other departments on set. And although not suitable for pulling focus, due to the substantial (for focus) lag of 0.08ms, it is a good option for video village.
