Building security / surveillance options

[Shawn Loftis]

We purchased a 8 unit property last year in Aurora, Colorado and are having issues with the homeless. The 8-unit is a 2 story split level with basically a long hallway on each floor with 2 units on each side of the hallway. There are 2 exterior doors on the building one on each end of the hallway. The homeless will basically come by during the day and break off a key in the exterior door which requires the tenants to prop open the door. This allows the homeless to come back at night and sleep in the hallways and/or laundry room. Obviously this is hurting our ability to retain quality tenants. We hired a security company to patrol the buildings which helped but it is cost prohibitive to do on an ongoing basis. We are hoping that we can go to a keyless entry solution and have some kind of alarm or alert when the door gets propped open in the future. We would also like to install some security camera's onsite to see how the doors are getting propped open in the first place so we can crack down on the practice. 

Anyone faced these types of issues in the past? Where there any good solutions? We reached out to a security company but they were looking to quote a $100k solution which isn't something we are going to be able to take on at this time. We are open to replacing both exterior doors and getting some kind of keyless entry solution in place. Curious what others people experiences have been. Any specific recommendations on doors / locks / access control / cameras?

We do have our own wifi / electricity at the building for continuous remote monitoring we just would like some recommendations from people of have been there and done that. 

Thanks!
