Frequently Asked Questions

What makes audio/video security essential for construction sites?

Construction sites are vulnerable to theft, vandalism, and safety incidents due to open perimeters, valuable equipment, and constantly changing crews. Audio/video security helps deter crime, provides real-time safety monitoring, and streamlines incident investigations to protect a project's bottom line.

How does video AI improve operational efficiency on construction sites?

Video AI automates the detection of risks like unauthorized entry, PPE violations, and unsafe behaviors. This means faster incident response, fewer false alarms, and the ability to audit progress remotely—saving time and reducing costly delays.

Can I use existing cameras with modern monitoring platforms?

Many leading platforms, including Spot AI, are camera-agnostic and support ONVIF-compliant IP cameras. This allows you to upgrade to AI-powered analytics and cloud storage without replacing all your hardware.

How do audio features like voice-down systems deter incidents?

Voice-down systems use live or automated audio warnings to challenge trespassers or correct unsafe behavior. This forward-looking approach is an effective way to deter criminal incidents before they escalate.
