The short answer
Security helps deter theft by increasing the chance that suspicious access or movement will be noticed, challenged through policy, and documented. Useful measures include visible officers, controlled entrances, credential and key management, randomized patrols, lighting, perimeter barriers, cameras, inventory records, and prompt escalation of anomalies. None of these measures guarantees that theft will not occur; the aim is to reduce opportunity and improve detection and response.
What to know
Start by identifying attractive assets and how they can leave the property. Map gates, loading areas, blind spots, key storage, vehicle routes, and times when supervision is lowest. Written post orders can require checks of defined locations, verification of after-hours removals, delivery logs, and immediate reporting of damaged locks or missing property. Portable camera towers may help cover open yards or temporary sites, while guards add human verification and response.
When an incident occurs, officers should prioritize safety, contact police or management under the response plan, avoid disturbing the scene unnecessarily, preserve relevant video or records, and document observations objectively. Arrow offers on-site officers, patrols, and portable camera towers; the recommended combination should follow a current site assessment and client-approved procedures.
