What security systems to use?

[James Sexton]

We have an old 9 unit, 4 story, apartment building that we just acquired 6 months ago (thanks bigger pockets!). We are working on cleaning the property up and badly need a security system with cameras on each floor.  The building does not have internet and when we had a Comcast tech come look they said to get internet on all floors we would need to hire an IT team.  Has anyone else come across this or have ideas? Thanks in advance!
