One video clip shows when police approached Paddock's door, it was blocked by a room service cart.
The first officer to enter the room did not have his body camera on, according to the Las Vegas Review-Journal.
Las Vegas police on Wednesday released officer bodycam video from the night of the nation's deadliest mass shooting in modern 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.
The videos show Paddock's arsenal of rifles scattered on the floor and on chairs in the room.
Police say he killed 58 people and injured hundreds more before killing himself as authorities closed in. "Looks like it might be a camera of some sort", the officer can be heard saying.
"A lot", another officer responds.
Las Vegas police had released a report and said Paddock acted alone and had not been radicalized by ISIS or any other terrorist organization.
The footage reveals the chaos and confusion the Las Vegas police encountered as they searched for the position of the shooter.
Officer body-camera video from the deadliest mass shooting in modern USA history shows Las Vegas police walking into a casino that's still packed and telling people to get inside and lock the doors. An officer told others to watch where they were stepping.
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.
Joseph Lombardo, the Las Vegas sheriff, has been critical of the fact that police have to release the body camera footage and other evidence. "For that, we apologize". "Further victimization is certain to occur and is something we wanted to avoid". Police had resisted release of the records, arguing that they had scant funds and resources to carry out the request and citing potential trauma to survivors and victims' family members.
Lombardo said more recordings and documentation would be released on a rolling basis.
"The dynamics and the size of this investigation requires us to go through voluminous amounts of information in order to draw an accurate picture".
The bodycam film broadcast on CNN shows the drama unfolding as police response to the massacre.
An officer is at one point heard asking another officer to examine a note Paddock left on a table. "There's someone shooting inside the casino!" an officer warns people in one room as they sweep the Mandalay Bay Resort and Casino. "Stay down! Stay down!"
More than 7 weeks after the shooting police are not any closer to determining Stephen Paddock's motive for the strike. It does not provide a complete view of everything police discovered in the room.
Las Vegas police used explosives to blast into a high-rise hotel suite where a gunman unleashed the deadliest mass shooting in modern US history and found him dead, with a cache of assault-style weapons and broken windows that had a view of a concert venue killing field, according to police body-camera videos.
