Need to stream video over a network using iOS devices? Transmitting video over wifi or Cat5e using an Apple tablet or phone can be really easy. This is how to do it.
A recent gig required live video and audio streamed from one building to a projection screen in another building some distance away. The gig came as a last minute request (the night before a morning event). I had little time to prepare. They were in a bind and didn’t have anyone else they could count on. Though I did not own very much video equipment, I knew I had to help. I had to be creative in order to accomplish the task. Here is what I did.
First, I broke the problem into 2 parts: audio and video. Figuring out an audio solution was easy, since I’m primarily experienced in audio and had all the gear for that portion. So the tough part was figuring out video. Another factor to consider was that the signals needed to be fairly secure (to prevent easy hacking), so wired was preferred over wireless options. My plan was to send audio over balanced audio cables and video over ethernet/Cat5e cable to reassemble on them together on the other end.
Second, I scoped out the location. The buildings were two small structures set on opposite sides of a small parking lot. A quick reading with my super handy laser distance measurer revealed the buildings sat about 100 feet apart. This measurement was helpful for figuring out how much cabling I need to run between the two locations. In addition to the distance between the two, there was also a height factor (the receiving location was on the second floor), plus there were interior distances that needed to be run. Altogether the total distance from the source to the destination required enough cable to reach somewhere in the ballpark of 200 feet.
Third, I needed to inventory my equipment list to figure what I needed to buy, if anything. Luckily, I found a nice iOS app that streams video quite reliably.
Video Signal Flow
This is the basic routing I came up with:
iOS Device with Video Source App > Wifi Router > Ethernet Cable > Computer with Video Destination App > HDMI Cable > Output Device (Display or Projector)
And here are the specific details of my setup:
- a newer iOS Device (iPad/iPhone/iPod touch) with good camera (I used an iPad Mini 2.)
- a video streaming iOS app (I used AirBeam by Appologics UG with its companion desktop app AirBeam Pro.)
- a wifi router (I used an older AirPort Extreme Base Station A1354. For increased security, I also made sure the SSID was not broadcast, the network required a WPA2 password, and the password was fairly long and complicated. Not a perfect solution, but much better than an open wide, password-free network.)
- Cat5e cable (I used cable rated for outdoor use since it was kind of rainy and wet outside.)
- an Apple computer with ethernet jack (I used an aged Mid-2010 MacBook Pro.)
- a video adapter for connection to video cable (I used one of these AmazonBasics Mini DisplayPort (Thunderbolt) to HDMI adapters.)
- a video cable (I used an HDMI to HDMI cable.)
- an output device (I used a projector.)
Here is a sketch of my set up:
I didn’t describe or diagram my audio setup as it was a little more traditional in approach. I may or may not write about that in another article.
