This isn’t directly related to Niagara Falls, but if you are a technical person, you might be interested to know with what equipment the Nik Wallenda Niagara Falls walk was filmed.
From ThomasNet News:
Toshiba Imaging (www.toshibacameras.com), a leader in high definition (HD) color video imaging, provided the point-of-view (POV) camera for Nik Wallenda’s successful, record-breaking tightrope walk over Niagara Falls on June 15, 2012. The tiny IK-HR1S high-def imager captured the sensational footage from the balance bar of the internationally-acclaimed tightrope artist during the 1,850-foot trek. The one-piece HD camera was waterproofed and mounted on the balance pole by Aerial Video Systems (AVS-www.aerialvideo.com), the company contracted by ABC to provide all the audio and visual communications for the historic event.
