Copy and pasting one of posts from a now closed thread. I would not be surprised if there is not surveillance footage from the hotel hallways.
Las Vegas casinos some of the most closely watched spaces in the world dont have video cameras in guest room hallways, an absence that hotel workers like Patrick, patrons and prosecutors say can act as a green light for crime.
Casino bosses say there is no need for extra security: Americas playground boasts more cameras per square foot than any airport or sports arena in the country, with thousands of high-tech lenses watching the gambling floors, lobbies and
elevators.

Yet The Associated Press found that 23 of the 27 major Strip casinos have no surveillance in hotel hallways or elevator landings. All but four of the 27 hotels are owned by MGM Resorts International, Caesars Entertainment Corp., Las Vegas Sands Corp. or Wynn Resorts Ltd.

That's from an incident in 2013 when a maid was attacked in the hallway. I don't think surveillance in the hotel hallways is nearly as important to the hotels as it is in the casinos. They care about protecting their money and making sure things are running smooth on the casino floor. They probably don't care too much what goes on in the hallways of the hotel. Well maybe now they do, but I don't think it was that much of a concern before this. JMO
The below link has some pics of the inside of a Vegas surveillance room. I only skimmed the article bc it's long, but it's interesting.
