Police found him dead from a self-inflicted gunshot wound when they entered his room. Guns are strewn around the room.
One video clip shows when police approached Paddock's door, it was blocked by a room service cart.
The footage does not show what the first officer through the door saw because he did not activate his body camera.
The Las Vegas police has released bodycam footage from inside the casino where Stephen Paddock killed 58 people and injured hundreds more in the deadliest mass shooting in the modern United States history.
The footage's release came after a judge sided with media organisations including The New York Times and The Washington Post that lobbied in court that the evidence be made public. But the police department had resisted calls from the media to release additional bodycam footage and 911 calls from the night of the mass shooting.
"So there is no conspiracy between the Federal Bureau of Investigation, between the (Las Vegas Metropolitan Police Department) and MGM (the hotel owner)".
Mueller gives list of questions to Trump's lawyers
Angrily reacting to the report, Trump said it was "disgraceful" that classified information was illegally leaked to the media. Mueller was appointed by Deputy Attorney General Rod Rosenstein in May 2017 after Comey was sacked .
"Breach! Breach! Breach!" one of the officers says.
"A lot", the officer wearing the body camera responds.
Police said Paddock, 64, acted alone, and his motive remains a mystery.
A preliminary report released in January said Paddock meticulously planned the attack, researched police SWAT tactics, rented hotel rooms overlooking outdoor concerts and investigated potential targets in at least four US cities.
Officers talking to each other question if there were any indications of two shooters. Officials also said they found "numerous" images of child pornography on the gunman's computers.
Joseph Lombardo, the Las Vegas sheriff, has been critical of the fact that police have to release the body camera footage and other evidence.
Barcelona midfielder Andres Iniesta to leave club at end of season
Iniesta was runner-up to Lionel Messi for the 2010 FIFA Ballon d'Or and achieved third place in 2012. But the Midfielder said he will not play in Europe after Barca because he can not play against them.
"We believe the release of the graphic footage will further traumatize a wounded community". He said he expected to release new materials weekly.
Lombardo said Tuesday that the department would release more recordings in batches in coming weeks. "Primarily, we are still investigating all the circumstances".
Days after the attack, police published harrowing recordings captured by officers' body cameras that showed the horror unfolding outside as the gunfire began. As they move forward, they're heard identifying a camera, spotting a rifle, and saying they're going to check under the bed.
Officer body-camera video from the deadliest mass shooting in modern US history shows Las Vegas police at the door of the gunman's suite, and one saying "Breach! Stay down! Stay down!"
Authorities have yet to pinpoint a motive for the attack, which galvanised oft-repeated appeals to tighten U.S. gun laws. Among them were pictures of the guns stockpiled in the room and a chilling view that the gunman would have had of the concert venue while he fired.
Some of the first officers to reach the Las Vegas hotel room where a gunman unleashed the deadliest mass shooting in modern U.S. history busted in with shields and found his body and assault-style weapons scattered around, according to police body-camera video.
