A local church wanted to be able to live steam their services from the far side of their parking lot. They had power in a small out building, but not internet. They were in the practice of running an extension cord to a sound board for audio including an FM transmitter.
The requirements for the live stream cart were:
- quick set up and tear down
- wireless bridge to main building
- durable enough to be loaded in a trailer with other AV gear for other events
- hold dual monitors
This was the end result:
The red cable coiled up on the keyboard plugs in to the PTZ Optics NDI camera.
The second monitor folds towards the first monitor. The video and power connectors for the monitors are easily accessible. No VESA brackets were needed – just lay out the VESA mount pattern and drill it through the 3/4″ birch plywood and mount with 1″ screws.
Folded up it’s ready to roll.
This is a Ubiquiti Unifi Mesh AP that is configured to connect with a Unifi Mesh AP mounted to the side of the building.
The wireless AP and the camera connect to this Ubiquiti Unifi PoE switch for power and network. The computer also connects to the switch.
This is a the back of the HP EliteDesk mini computer. The EliteDesk line has lots of USB ports and enough CPU to handle running OBS and PowerPoint at the same time.
The front of the EliteDesk has USB ports that are accessible for the USB keys, etc.
The mini computer is mounted to the road case with a VESA mount bracket so it is secure during travel, but can be quickly disconnected for troubleshooting or maintenance.
These 3″ wheels make it easy to roll across the parking lot and lock in place during use.
The PTZ optics camera sits on a tripod that is stored in the bottom of the road case when not in use.
The camera is stored in a plastic case and put in the bottom of the road case when not in use.
It’s probably about 150′ across the parking lot from where the Ubiquiti Unifi mesh AP is mounted on the building. The APs have no connectivity issues at that distance.
The total cost for the project was about $2,600 with $1,000 being the PTZOptics VL NDI HX ZCam HD IP Network Camera with 4.4-88.5mm Lens.
