Frequently Asked Questions
Parking lots are often the most vulnerable areas for retail crime, including vehicle break-ins, catalytic converter theft, and loitering. Our guards conduct randomized foot and mobile patrols of parking facilities, paying special attention to dimly lit corners, perimeter fencing, and high-traffic entry points. We also monitor for suspicious vehicles circling lots, assist with escorting employees to their cars during late-night closing shifts, and document any security gaps such as malfunctioning lighting or blind spots. For shopping centers with multiple tenants, we coordinate with property managers to establish consistent patrol schedules that align with peak foot traffic and after-hours closure times.
Construction sites are frequent targets for equipment theft, vandalism, and trespassing, especially overnight and on weekends. We provide both armed and unarmed guards specifically trained in construction site security, including logging all vehicles entering and exiting the site, checking tool and material storage areas for signs of tampering, and conducting irregularly timed patrols to prevent predictable patterns that thieves could exploit. Our officers also document any damage to fencing, gates, or temporary lighting and provide daily digital reports to project managers. For larger developments, we can deploy mobile patrol units that rotate between multiple nearby sites throughout a single shift.
Yes, we specialize in temporary event security for community gatherings of all sizes. For events like street fairs, car shows, or holiday celebrations, our officers focus on access control at entry points, monitoring for alcohol-related issues, managing pedestrian flow along congested pathways, and providing visible deterrence for theft or disturbances. For youth sports tournaments at local parks and fields, we offer family-appropriate unarmed security that prioritizes conflict de-escalation between spectators, lost child response protocols, and parking lot safety. Every event receives a customized security plan based on expected attendance, venue layout, duration, and any specific concerns raised by organizers or city officials.
