Physical Security Presence
Professional Manned Guards & Anti-Squatter Teams
Prevent Illegal Occupancy
A physical guard presence is the only 100% effective way to stop squatters. Our officers physically verify that vacant homes remain empty and secure, preventing "adverse possession" claims before they start.
Contractor & Vendor Verification
Theft often happens from the inside. We verify that only authorized developer security contractors and vendors are accessing the site after hours, protecting appliances and materials.
Community Relations
For occupied or semi-occupied phases, our guards act as ambassadors—deterring crime while making new residents feel safe and welcome in their new construction neighborhood.
Monitor Vacant Lots & Streets with AI Surveillance
Secure new construction areas and streets where power may not yet be reliable or available. Solar-powered AI trailers provide 24/7 monitoring for vacant lots and tract phases without utility connections.
