Protect the Site. Monitor the Progress.
Rugged, rapidly deployable security and surveillance solutions to protect valuable equipment and monitor job site productivity.
ZEI provides job-site security and the infrastructure rough-in that becomes the building's permanent low-voltage system. Solar / cellular surveillance trailers, equipment tracking, time-lapse video, and structured cabling that survives from foundation through fit-out — handled by the same team across both phases.
Technology Partners
A representative construction sites environment of the kind ZEI engineers infrastructure for.
What this industry deals with.
- Active sites with no permanent power, internet, or fixed infrastructure
- High-value tools and equipment exposed to theft and weather
- Permanent low-voltage rough-in that must coordinate with electrical, mechanical, and structural trades
- Disputes and damage claims requiring documented record of activity
- Multiple GCs and subs requiring temporary access controls
Jobsite Security
Temporary and permanent solutions for dynamic environments.
Solar & Cellular
No power? No internet? No problem.
Self-contained surveillance trailers and pole cameras that operate entirely off-grid.
Time-Lapse Video
Document the build.
Automatically generate high-quality time-lapse videos for stakeholders, marketing, and dispute resolution.
Asset Tracking
Know where your tools are.
GPS and RFID tracking for heavy machinery and high-value tools to prevent theft and misplacement.
Proactive Deterrence
Stop theft before it happens.
Cameras equipped with strobe lights and loud speakers that trigger automatically when intruders are detected after hours.
How this gets applied.
Solar / cellular surveillance trailers
Self-contained units with PTZ cameras, AI analytics, and audio talk-down to deter theft on sites with no infrastructure.
Time-lapse and progress video
Daily time-lapse documentation for stakeholders, marketing, and dispute resolution; cloud-stored and shareable.
Permanent low-voltage rough-in
Structured cabling, conduit, and backboxes installed during construction so the permanent security system commissions cleanly post-occupancy.
Job-site access control
Temporary credentials for GCs, subs, and inspectors with audit logs that document who was on site and when.
Systems we typically deploy.
An opinionated, ordered stack — what most construction sites engagements include, in priority order.
Video Surveillance
ZEI engineers commercial video surveillance systems built around modern IP cameras, edge AI analytics, and cloud or on-premise video management
Intrusion Alarm
ZEI engineers commercial intrusion detection systems that integrate with video surveillance and access control to verify threats before responders are dispatched
Access Control
ZEI deploys cloud-managed and enterprise access control across single-door deployments and multi-site campuses
Networking & Wifi
ZEI engineers commercial network infrastructure that the rest of your facility depends on — structured cabling, managed switching, Wi-Fi 6E / 7, next-generation firewalls, and SD-WAN
Physical AI
ZEI deploys physical AI — computer vision, behavioral analytics, and machine learning — that turns existing camera infrastructure into intelligent sensors
Entry Gates
ZEI installs and services industrial-grade entry gates — slide, swing, barrier, and crash-rated — engineered for high-cycle reliability and integrated with access control, LPR, and intercoms
Built to the standards that apply.
OSHA documentation
Optional video documentation of safety-related events for OSHA review and dispute resolution.
AHJ rough-in inspections
Permanent low-voltage rough-in coordinated with the AHJ alongside electrical and fire-alarm inspections.
Deployment Phases
Security that evolves with your project.
Active Construction
Temporary, ruggedized security for the building phase.
- Mobile surveillance trailers
- Solar-powered cameras
- Cellular connectivity
- Remote guard monitoring
- Equipment tracking
Permanent Infrastructure
Transitioning to the final building security system.
- Structured cabling installation
- Access control rough-in
- Permanent camera mounting
- Network rack setup
- System commissioning

Stopping Copper Theft: How Radar-Based Detection Cut Substation Losses by 98%
Copper theft at electric utility substations is not a nuisance crime. It is a safety emergency.
UPS Sizing and Battery Runtime Calculations for Security Infrastructure
A security system that loses power is no security system. This guide covers UPS sizing, runtime math, and battery selection for cameras and access control.
