Best security camera system for small apartment complex's

[Mark Gray]

Recently bought an 8 unit apartment building, its in a decent area but the previous landlord didn't do the best job of taking care of the place so I'm cleaning out his trash. 

Does anyone have any good recommendations for security camera's? looking for something that's cloud base, wired (going to run everything through the attic), with sound, at a decent price. 

Thanks in advance!!
