| Visible deterrence | Strong physical and psychological presence with active patrol; approximately 99% deterrence in AGD’s internal operational experience | Visible human presence that supports rules and access control | Depends on camera visibility, signage and response process |
| Observation | Handler observation plus canine hearing, scent and awareness | Human observation, communication and reporting | Remote or recorded visual monitoring within camera coverage |
| Mobility | Moves with the handler across gates, fence lines and assets | Patrol depends on staffing, post orders and property size | Fixed or repositionable view; blind spots must be managed |
| Cost structure | Customized; may be highly economical for qualifying extended coverage | Labor and supervision cost scale with hours and headcount | Equipment, connectivity, maintenance and monitoring costs vary |
| Best use | Perimeters, construction, yards and properties needing unmistakable deterrence | Reception, checkpoints, customer-facing areas and human decision-making | Alerts, documentation, broad viewing and off-site monitoring |
