Police released almost three hours of footage which shows two officers going through the floors of the Hotel Mandalay where Paddock was holed up after opening fire on concert goers attending the Route 91 Harvest Festival last October.
"A lot", another officer responds.
The videos were released as part of a cache of evidence after media outlets sued Las Vegas police.
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 USA cities.
The first officer to enter the room had not activated his body camera, but the scene was recorded from the bodycam of an officer following closely behind.
The footage was released after several media organizations, including CNN, argued that police information on what happened that night should be released.
In March, video released from hotel and casino security cameras shows Paddock appearing to be "an ordinary hotel guest and casino patron", as NPR's Scott Neuman notes, even as he brings suitcase after suitcase of weapons up to his room.
The videos showed officers inside Paddock's room looking behind curtains. An initial clip shows officers plugging their ears as an explosive charge breaches the door to the suite.
"He has a intricate camera system set up, out to this", the officer wearing the camera says, pointing out the open door to the hallway.
A home that the Las Vegas shooter owned in Reno when he carried out the deadliest mass shooting in modern USA history sits vacant in an upscale neighborhood.
The videos were released as part of a court order after USA media outlets sued.
As for why it took this long to reveal the bodycam footage, Las Vegas Sheriff Joe Lombardo claimed at a news conference this Tuesday that he was justified for initially refusing to do so.
An officer told BuzzFeed news additional footage will be released in the coming weeks.
'What is seen on those videos in no way changes the facts that we were able to clarify for you shortly after the crime, ' he said.
The videos came out after the Nevada Supreme court ruled the police release the body cam footage.
Officers are seen scrambling to figure out where the shots were coming from.
"Did he write something on that", one officer asks.
"I want the community to know the release of the videos, 911 and documents will have a significant impact on the victims of this tragedy".
The other materials will be made public "on a rolling basis", Lombardo said. 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.
