Security system /cameras for your rentals

[Zk Lani]

Hi guys, I had one of my units broken into over Christmas, broke the window, stole some electronics and one of the property keys. It’s a college 4plex renting all girls. I’m very pissed and would like to secure the property especially that girls live there. I’m going to change the locks tomorrow, window got fixed, but what camera/alarm system do you guys recommend?
