The garage doesn't have access to any other part of the building, it's on Main Street, and it already has surveillance installed. 

I am looking for a security system for a 10 unit apartment building to include tenant entry security, as well as, camera surveillance of the interior and exterior of the building.  

Tell the owner to add video camera surveillance and post "You are being recorded" signs all over the property.

I have been in the Information/Cyber Security world for the past 8 years.

I'd also add that you should put up a sign saying the area is under surveillance, install a camera and have her call 911 at the first sign of trouble.

Unfortunately, we are now in the midst of the COVID-19 pandemic and leasing is very slow but we do get the first few residents set up in their new apartment homesJuly 2020: Community is 95% occupied with average rents at $675/month (range from $613 - $735)Rehabilitation included: Rebranding and signage, exterior pavement and concrete, fencing around the community, restoration of the brick and masonry, weatherproofing, gutter and roof repair, landscaping and lawn care, security surveillance, interior renovations included new flooring, paint, appliances, sinks and countertops, low flow facuets, repairs to the plumbing and electrical systems, new water heater. 

Having a strong math and science background, and working as a cyber analyst, I would confidently say I'm an integrator.

I am a cyber-security engineer from Connecticut trying to escape the rat race known as the 9-5 and start a career in real estate.

@Sofiya Cherni consult a RE attorney - if you have proof or testimony from neighbor of long term visitors, or potentially video surveillance evidence, then you would have a case in the court of law.

Info on fencing, surveillance, climate controlled vs. outdoor, concrete vs. asphalt vs. gravel.
