How Deep Sentinel Helped a Property Management Firm Cut Crime by 63% at a Large Multifamily CommunityTitle

When you’re managing over a thousand apartment units, security challenges can make or break your property’s reputation and profitability.

This real estate investment firm, known for its data-driven approach to value creation and risk management, faced this exact challenge at one of its flagship multifamily properties. Despite deploying multiple guards and traditional systems, the property continued to experience serious crime and safety concerns.

“We had recurring issues—vagrancy, drug sales, even violent incidents in common areas,” explains the firm’s Senior CAPEX and Renovations Manager. “We brought in up to six guards, but it didn’t fully resolve the issue. It’s always been a challenging site.”

The challenges mirrored those of many large, open-access residential communities:

• Unauthorized access to common areas and hallways

• Loitering and suspected illegal activity in shared spaces

• Large parking lot gatherings that frequently escalated into violent incidents

• Property damage, including one arson incident that left residents on edge

The company had already invested heavily in conventional approaches—armed guards during peak hours, mobile solar surveillance trailers, and reinforced access controls. But these methods were reactive, capturing evidence after incidents occurred instead of preventing them.

They needed a proactive, always-on solution capable of deterring and intervening in real time—without adding costly, round-the-clock personnel.

The results: Deep Sentinel delivered a 63% crime reduction, zero break-ins, and 50% fewer law enforcement calls at the multi-family property.Title

With Deep Sentinel in place, the multifamily community saw immediate and measurable improvements across every key security metric that mattered most to the property.

The transformation was especially noticeable for the on-site security teams.

“We used to go from building to building trying to figure out where the trouble was,” said an on-site security supervisor. “Now the system flags issues and sends alerts before we even get a call—like when someone’s loitering near the dumpsters. We’ve eliminated most of the transient activity… it’s definitely a much safer place now.”

A regional crime analyst confirmed the shift:

“We’ve observed a noticeable decrease in that type of activity since the system was installed and on-site security was reinforced.”

The success of this deployment has influenced the property management firm’s broader strategy. The company now includes AI-powered surveillance assessments as part of its due diligence for new acquisitions—particularly those in high-density or higher-risk areas.
