It was a traffic camera. They record intersections and are as clear as a bell if on the right infrastructure and this looks like it was on a good infrastructure. I have seen as clear traffic monitoring videos before.
I install wireless monitoring systems and under the right circumstances even their transmissions are as clear as that video. But if the system is hard wired and on a T1/E1 then you better be getting that clear of a picture or you've got a problem.
I guess his mama didn't teach him to "look both ways before crossing the street".
I've crossed streets here in Phoenix, and I look up and down the road, and I won't cross until I know there isn't anything near me that I can't dodge should the situation arise. You have to always be aware. Not walking along in a daze, as the person in the vid seemed to be.
Snooping around snopes, I came across the story behind this and the follow up.
Crash Landing
Claim: Video shows car striking another vehicle in an intersection, sending the second car into a pedestrian.
Status: True.
Origins: It's a chilling scene: a video clip shows a vehicle as it speeds through an intersection and runs broadside into another car; a pedestrian crossing the street breaks into a run to run to get out of the way of the out-of-control vehicles, but the struck car rolls on top of him. The video is all the more chilling because it isn't a scene from a movie, nor is it the product of special effects wizardry it's the real thing, captured by a red-light enforcement camera.
The accident seen in the video occurred at 12:40 p.m. on 23 May 2004 at the intersection of Third Street and Edwin C. Moses Boulevard in Dayton, Ohio. Betty J. Hayslip, 75, of New Lebanon, driving a PT Cruiser, ran a red light and struck a Suburu driven by Albertina L. Walker, 41, of Dayton. The collision caused the Subaru to roll over one and a half times; it came to rest upside-down and in the process crashed into pedestrian Scott Tegtmeyer, 42, of Dayton.
Tegtmeyer, who was crossing the street in the same direction as the PT Cruiser and had just reached the curb on the opposite side, can be seen in the video breaking into a desperate run as the collided vehicles bear down on him. He could not react quickly enough, however, and the Subaru rolled atop of him, dragging him several feet across the intersection. Although medics who found Tegtmeyer's bloodied body amidst a sea of broken glass initially pronounced him dead at the scene, he began breathing while in transit with paramedics and was fully resuscitated by doctors. (As of 2 June 2004, Tegtmeyer was reported as being in serious condition at Miami Valley Hospital.)
Investigators said that at the time of the accident the crosswalk signal was red, and therefore Tegtmeyer should not have been crossing the street. They also reported that Tegtmeyer miraculously escaped alive because the dent in the side of the Subaru caused by the crash created a hollow space that allowed the vehicle to roll over him without crushing him to death. Neither vehicle was carrying any passengers, and both drivers escaped with only minor injuries.
The crash was captured by one of the automated red-light enforcement cameras installed at a dozen intersections around Dayton to help reduce crashes caused by drivers running red lights. Each camera records 12-second motion videos used to issue citations to offending motorists.
