Security cameras at Halle Berry's house failed to capture the U.S. Thanksgiving Day brawl between her ex-boyfriend Gabriel Aubry and fiance Olivier Martinez.

The two men were hospitalized after the vicious fight, which is said to have been sparked by Aubry's bitter custody battle with Berry over their daughter Nahla.

Aubry has since placed the blame on Martinez, but a new report suggests there is no video footage to determine who was actually responsible for starting the showdown.

Law enforcement sources tell TMZ.com detectives have reviewed the available footage and confirmed the bust-up occurred outside of the cameras' field of vision, dismissing Aubry's claims that the tape could have been erased.

Berry was reportedly advised by police to turn her security cameras towards the fences surrounding her property in order to capture a possible intruder after problems with a stalker last year.
