UPDATE: With two of some of the most protected people in the nation at the Thomas & Mack Center Wednesday night, security is heightened.
UNLV is campus is now surrounded by gates, concrete barriers, and even shipping containers that are acting as a sort of wall.
According to Las Vegas police, they will also have a very large police presence at Wednesday night's presidential debate.
They didn't disclose how many officers will be stationed at UNLV, since a large number will be undercover.
LVMPD says they are using a very similar security model that they use every year for New Year's Eve, with an all-hands on deck situation.
The barriers and gates surrounding campus are expected to start coming down Thursday morning.

On Tuesday, the Commission on Presidential Debates held rehearsals for Wednesday's event. Stand-ins hired by the Commission played the roles of the candidates and the moderator, while crews will check lighting, sound, and other equipment.
UNLV campus and surrounding roads will be congested or closed altogether over the next two days while crews finish debate preparations. For more information on traffic, click here.
13 Action News also sat down with the Secret Service who said there have been no credible threats ahead of the debate.
They are working in connection with the Las Vegas Metropolitan Police Department, Las Vegas Fire & Rescue, Nevada Highway Patrol and UNLV Police to secure the surrounding area around Thomas and Mack.
"Going into the event itself, yes there will be screening areas. For the most part, if you are not going you won't be able to just walk and look in," said Brian Spellacy, special agent In charge.
UNLV and the Las Vegas Convention and Visitors Authority have put up nearly $8 million to host the debate in Las Vegas.
Organizers at UNLV said they switched the curriculum for nearly 80 courses to educate students on the candidates.
