Best Security Camara system?

[Mackaylee Beach]

Hey BP!

I am currently shopping around for a Camara Security system for my 10unit apartment complex, located in Grandview, MO.

I am wanting to be able to monitor all exterior corners along with entrances and common areas in the interior - it would be about a total of 15 camaras. 

I am aware that I will most likely also need to have internet service - nothing fancy but enough to be able to manage camaras. 

Any recommendations on either internet or security system would be greatly appreciated!!
