Long.Īdditional features allow not just 1:1 link, but 1TX:2RX, 2TX:1RX, all using a single channel. And perhaps most useful is that it runs on 5VDC, and the supply is rated at 2A… Which means I can use a USB battery to power the transmitter and the GoPro (and a 20Ah slice will run this rig All. Airtime usage is quite efficient, around 4%, which is shocking for a video application. It’s running 802.11ac on a 20MHz channel (and the channel selection allows 10 different channels, which tells me it’s running on UNII-1 and UNII-3 and avoiding the DFS bands).
So I hauled out my Ekahau Sidekick and its spectrum analyzer to see how well-behaved it would be… And I was pleasantly surprised to discover that it was very well-behaved on the Wi-Fi spectrum… because it’s actually running Wi-Fi! Since I am a wireless network engineer by profession, I had significant concerns about how well this would behave in the spectrum – it advertises that it uses 5GHz, and I expected it to grab as much spectrum as it could (as most wireless video devices tend to), and walk all over everything else in the band. This could also potentially be used for linking live UAS footage back to a switcher.
They offer quite a wide assortment of gizmos to move video signals around.
It’s also able to send IR control to the receiver.Īs it turns out, GoFanco is starting to make a name for themselves in the video accessories market for both pros and consumers, not entirely unlike how BlackMagic got their start. I immediately picked up another set to run a mobile confidence monitor cart. Not only was it easy to set up, the picture quality was excellent, and latency almost nonexistent. I needed to send a GoPro feed back to the booth without running cables all over the floor (or worrying about the GoPro’s live streaming latency - it uses HLS with a real short segment size– and getting that stream into the switcher was not a trivial task).Īs is so often the case with these “off-brand” (or less well-known brand) devices, my expectations were low, and I fully expected to return it after a week. If ((looper = Looper.A few weeks ago, I went to Amazon and picked up a cheap wireless HDMI transmitter to solve a camera connection challenge at the church. remember which looper is associated with the AudioTrack instantiation Int bufferSizeInBytes, int mode, int sessionId) Public AudioTrack(int streamType, int sampleRateInHz, int channelConfig, int audioFormat, byte buffer = new buffer int count while(true) //关闭并释放资源 audio.stop() audio.release()
