The WiMi6220 Wireless 3G-SDI & HDMI H.264 Decoder/Receiver from Nimbus pairs with an optional WiMi6220 transmitter as a point-to-point Wi-Fi transmission system with a 4921' range and only 80ms latency. With both units featuring built-in 5 GHz Wi-Fi, no additional network connection is required. This unit can be powered using the included Gold mount battery plate or via the included power adapter.

The receiver accepts up to a 1080p60 SDI or HDMI signal encoded in H.264 by the transmitter, and it decodes and outputs it as video. Up to four receivers can be paired to a single transmitter for multicasting over the same range and with the same near-zero delay.

An Ethernet port, which allows for CCU/PTZ camera control, can also be used for wired connectivity and 1080p60 transmission with a Cat 5e cable. The WiMi6220 receiver features an RS-422 interface and a two-way talk-back audio jack. With a corresponding audio jack available on the transmitter, the talk-back port allows connecting a headset mic for communication with talent. For mounting, it offers a 1/4"-20 mounting thread on the bottom.

Related Questions and Answers

Q: 1. I cannot get a feed with SDI at 59.97fps. Transmitter and receiver say 60pfs and my decklink says its receiving 30fps. Any help?

A: The Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System will only output an even frame rates of 24, 25, 30, 50, 60. It cannot output 29.97 or 59.94. If your system requires 29.97 or 59.94, the signal from the receiver will not be compatible, unless a frame rate converter is used. A scaler such as the Blackmagic Design Mini Converter UpDownCross HD, could help to convert the frame rate appropriately. https://bhpho.to/3Qd2icc

Q: 7. Can I record wireless externally on the atomos if I hook it up with the Shogun?

A: Using the Hollyland Mars 400S PRO SDI/HDMI Wireless Video Transmission System as a way to get the signal from the camera to the recorder should work; we see no red flags to say no. However, any blip or drop or defect in the signal will be recorded. We suggest that direct recording is the correct method.

Q: 9. Hello, what are the exact RF frequencies used for this item? I believe there are 12 different "channel" presets, but I would like to know the exact frequency in Hz because we have been struggling with some interference. Hopefully this information will help us to coordinate our RF environment. I need more detail than just "5Ghz".
