Another video showed a woman getting out of her bus seat to check an accident scene before returning to her seat to sprawl out and instruct her 6-year-old daughter to feign injury, too.
SEPTA pays about $40 million a year in accident claims, and payouts have risen by more than 10 percent in the last two years, Casey said.
"A picture is truly worth a thousand words in these cases," Williams said. "Bus accidents where everyone on the block falls down and says they were injured - those days are over."
About 45 percent of SEPTA buses and all Broad Street and Market-Frankford subway trains are equipped with video surveillance cameras. SEPTA plans to equip all buses, subways, and trolleys with video cameras by January 2013, and the newly arriving Silverliner V commuter railcars also have cameras.
In the 12 months ended June 30, 2,389 SEPTA passengers were injured or claimed to have been injured. And 3,627 SEPTA vehicles were involved in accidents.
SEPTA officials on Thursday displayed footage from six incidents in which passengers or others were prosecuted for submitting false injury claims.
In five of the cases, seven claimants were sentenced to probation terms and ordered to pay as much as $16,000 in restitution and court costs. In the sixth case, three claimants await trial, facing charges of insurance fraud and attempted theft by deception.
Claimants in the six cases had produced $300,000 in medical bills, Casey said.
Williams said the videos would help his office prosecute fraudulent accident claims.
Casey said he hoped the heightened crackdown convinces passengers and others that SEPTA is not a patsy for false claims.
"They dream of a SEPTA payday," Casey said, hoping to dispel what he called "an urban myth" that SEPTA is an easy mark.
