Add up to 1080p60 wireless video transmission to your gimbal, mirrorless, or DSLR camera rig using the lightweight Mars 400S PRO SDI/HDMI Wireless Video Transmission System from Hollyland. The transmitter provides HDMI and SDI inputs and the receiver offers SDI and HDMI outputs. It features extremely low 0.1s latency with line-of-sight transmission up to 400' to the receiver and up to 300' to the Hollyview Wi-Fi app. For a strong line-of-sight signal, the system includes two external antennas on the transmitter and two on the receiver, and one is included as a spare.

Using the Hollyview app for iOS or Android, you can monitor your video transmission in real time via a Wi-Fi connection as well as live stream directly from the receiver via your computer using a USB Type-C adapter. The app also allows you to install optional channel scanning firmware enabling you to easily find the strongest transmission signals. The transmitter can simultaneously transmit to up to one receiver and two apps, or to a total of four apps without the receiver. The redesigned body makes it a low-profile choice for your rig, and it features multiple fan modes to keep it cool or quiet when you are shooting.

The 400S PRO transmitter and receiver are compact in size, feature a bright OLED display for configuration, and an integrated shoe adapter with a 1/4"-20 mounting thread for different mounting options. Each unit can be powered using a USB Type-C source, the included locking DC power adapter, or by using a separately available L-series type battery using the integrated battery plate.

Fits my 2026 civic sport perfect!
Size: AF151
No issues, fitment is perfect. Great quality for an excellent price. Dealer wanted like $24 for a basic one. Nah I'm good I'll just go on Amazon and get it for $8. Took 30 seconds from start to finish can't get any easier.

Fits well and installs easily.
Size: AF997
This filter looked about the same as the OEM filter. It installed in about a minute. The quality appeared to be fine. It was protected in a cardboard box. It fit my 2014 Subaru Outback perfectly. I just installed it an hour ago so I don’t have any long term observations about longevity or effectiveness. I can’t see any reason why it would not work as well as the original, it seemed identical.

Great fit and quality
Size: AF113
Not a complicated product, but after going to 2 different auto parts stores and this not being in stock, Amazon to the rescue. Arrived the next day and the quality is definitely on par with “store brand” ones from retailers. Definitely cheaper as well.
