PTZOptics is quickly becoming a favorite the education market for flexibility of video output options. From live streaming sporting events to distance learning for University level courses PTZOptics has a lot to offer the educational space. Check out cases studies below that outline use cases with Willamette University, Indiana University of Pennsylvania and the Frisco School of Music.
From Basketball to Soccer, Willamette University live streams sporting events to athlete friends and families
Willamette University is a small liberal arts school located in Salem, Oregon where Christopher Sabato, the Assistant Director of Athletics for Media, organizes live broadcasts for the sports teams. From outdoor soccer matches to indoor basketball games, Sabato shares with us his techniques for live broadcasting these events and how the students families watch from out of state.
At Willamette University, the majority of the student population comes from out of state making it important to the Athletics Department that these families are able to watch the live sports broadcasts online. Using a selection of live streaming hardware and software which includes PTZOptics cameras, Wirecast, Magewell capture cards, xKeys controllers and more, Sabato regularly produces high quality live broadcasts the schools sports fans enjoy all season long. At the end of the day, it’s all about the fans that cannot make it to every game who are now able to watch live and enjoy the broadcasts from the comfort of their homes.
For outdoor broadcasts during the Soccer season Christopher uses a PTZOptics 20X-SDI camera housed an outdoor enclosure to capture all the action using a PTZ joystick controller. The Dotworkz outdoor camera enclosure is designed for permanent outdoor use and includes two weather sealed cable ports which Sabato uses for HD-SDI video and RJ45 converted to DB9 to be used for camera control with the HuddleCamHD joystick. The camera captures all the action from high above the field mounted on top of a SkyHawk TriPod mount made by US Sports Video. This giant tripod allows Christopher to follow the direction of game play from high above the athletes on field. “I don’t have a big production crew. So everything has been designed to be operated by myself or one other work study student.”
During Basketball season, Sabato uses 5 cameras to produce a professional video broadcast with the PTZOptics Producer Kit, Wirecast 7, HDMI & HD-SDI Magewell capture cards and the xKeys 24-button controller. The broadcast quality looks like it could be available on ESPN and Sabato has used a few IP networking techniques to pull in the live scoreboard timer he explained for us. “I have a clock camera setup using NDI and Newtek’s Connect Pro that came with the producer kit with effectively zero latency.” Using a clock camera as you can see in the picture above, Sabato is able to take the video feed and crop just the timer and shot clock for his game title in Wirecast. With a little Wirecast magic, Sabato is able to layer the live shot clock and game time onto his virtual scoreboard title.
During every live broadcast, Sabato tries his best to include a play by play announcer audio feed “It’s our goal to have play by play in all our sports broadcasts. ” Once the game starts a dedicated play by play announcer will handle all audio including ad spots bumpers and pre-recorded interviews. The Technical Director can play video overlays, with no audio, to match what the PxP is sending. The Technical Director mixer is sending an aux out to a Galaxy Audio Anyspot wireless receiver. The play by play audio workflow is explained below along with the entire video/audio system outline.

Willamette University Basketball Setup
- 5 Cameras
- 1 x JVC GY-HM200SP
- HDMI Magewell
- 2 x endline cameras mounted under the hoop. CV502-MB, CV505-MB
- SDI Magewell
- 1 x PTZOptics 20x SDI
- RTSP (until NDI Firmware is available) POE
- 1 x Canon HV20
- NDI via Newtek Connect Pro via HDMI Blackmagic Intensity Shuttle
- 1 x JVC GY-HM200SP
- Wirecast 7 running on the PTZOptics Producer Kit Skull Canyon NUC
- Added Skull Canyon Expansion Ring for additional USB ports including 2 USB 2
- Logitech wireless mouse and keyboard (these are notoriously finicky with USB 3 but this is mitigated by using the added USB 2 ports)
- X-Keys 24 – also using usb 2 ports to free bandwidth on the USB3 bus
- Allows quick access to graphics, scoreboard and replay. 24 keys wasn’t enough I should have went bigger.
- Thunderbolt 3 USB hub – Two of the Magewell cards are plugged in to this hub.
- The NUC couldn’t support three capture cards on its single bus.
- Mounted and enclosed in an SKB Studio Flyer Waterproof Carry-on Rack Case – 2U
- CAT6 and siamese RG58 coaxial cable.
- Siamese RG58 coaxial cable from the control area to the two endline Marshall cameras for power and video.
- CAT6 from the Control area to the network closet
- One for the streaming computer
- One for the PTZOptics 20x SDI, including POE for power
- HDMI from the Canon HV20 to the Network closet
- Laptop with Newtek Connect Pro and Blackmagic Intensity Shuttle
- It was too far to run hdmi and I didn’t have any HDMI to SDI converters.
- Play-by-play at the table
- XLR cable from the mixer on the table to the control area.
- Ingested by the JVC and sent to wirecast via SDI
- Once the game starts PxP person handles all audio including ad spots bumpers and pre-recorded interviews.
- For almost 10 years we have been streaming video with just a camera and PxP. We are upping our production with a technical director this year, but doing it slowly.
- Technical director can play video overlays with no audio to match what the PxP is sending.
- The TD mixer is sending an aux out to a Galaxy Audio Anyspot wireless transmitter / receiver.
- Plugged into the PxP mixer tape in and goes to PxP headphones but not out the master mix.
- TD can adjust what input are being sent to the PxP via the AUX control. To talk to PxP just turn up AUX on his mic.
- Audio from wirecast is sent via NUC out into the TD mixer and sent back to PxP via AUX.
- The TD Mixer doesn’t have any effect on the audio output to the stream. It’s for communication between TD and PxP
- Because this is going back to PxP it has to be a mix minus so Wirecast is not monitoring the audio from the JVC camera, but it it sending the out to the stream.
- To hear PxP Audio out of the JVC is plugged into the TD Mixer.
- XLR cable from the mixer on the table to the control area.
Musical Performances Case Study
The Frisco School of Music provides exceptional music lessons in Frisco Texas (TX). Students can learn to Play; Piano, Guitar, Voice, Violin, Drums, Strings and More! When it comes time for performances Frisco School of Music uses Wirecast to live stream the events using PTZOptics HD-SDI cameras. Because the cameras are mounted in various locations in the auditorium Frisco School of Music is using the RTSP streaming capabilities over Cat-5 network cabling. Wirecast will take in the RTSP streams over your network and allow advance video mixing and production. Below we have live test footage from a recent performance.
Frisco School of Music in Frisco, Texas has shared from test footage from (4) PTZOptics 12X-SDI cameras. Frisco School of Music uses Wirecast streaming over IP with the PTZOptics cameras IP video output. The HD-SDI video output is a secondary option they use with a black magic video input card for their PC. As you can see the video stream is clear and low light scenarios look great.
Higher education is using the simultaneous streaming capabilities to equip rooms for web conferencing while at the same time accommodating HD recording platforms such as Panopto and MediaSite Recorders. With web video conferencing software such as Skype, GoToMeeting and Zoom.US becoming so popular in the education space it is ideal to have a camera that can support existing hardware and newer online meeting technologies. For distance learning our remote PTZ control capabilities allow both ends of a video call access to the rooms camera. This type of control is being used by teachers to simplify camera control down to a simple mouse click to direct the camera to the area of attention.
