Problems We Solve

Where current systems fall short.

  • Operators staring at dozens of monitors with no useful signal
  • Footage that is unusable as evidence (low resolution, gaps, no metadata)
  • Storage that runs out before the legally required retention window
  • Cameras that cannot be searched by person, vehicle, or attribute
  • Disconnected systems where video, access events, and alarms cannot be correlated
Core Capabilities

Intelligent Capabilities

Our video systems do more than just record. They actively analyze your environment to provide actionable intelligence.

Smart AI Analytics

Stop staring at blank screens.

Advanced edge-based analytics detect people, vehicles, and unusual activity in real-time, sending proactive alerts before incidents escalate.

Mobile Access

Your facility in your pocket.

Securely access live feeds, review footage, and share clips directly from your smartphone or tablet, anywhere in the world.

Low-Light Performance

Evidence doesn't happen in the dark.

Next-generation sensors and IR illuminators provide crystal-clear, full-color footage even in near-total darkness.

Unified Ecosystem

Not just cameras.

Integrate your video surveillance seamlessly with access control, intrusion alarms, and intercoms for a single pane of glass.

Typical Components

What gets installed.

A real deployment is more than the headline product. These are the components we typically specify and integrate.

IP cameras

Fixed dome, bullet, multi-sensor, and PTZ cameras from NDAA-compliant manufacturers (Axis, Hanwha, Avigilon, Verkada).

Edge analytics

Onboard processors that run object classification, line-crossing, and behavioral analytics directly on the camera.

NVR / cloud VMS

Recording and management platform — Genetec, Milestone, Avigilon, Verkada, or Eagle Eye depending on architecture.

PoE+ switching

Managed switches with VLAN segmentation and per-port PoE budget for camera power and surveillance traffic isolation.

Structured cabling

BICSI-compliant Cat6/6A or fiber backbone with proper bend radius, dressing, and labeling.

Storage & retention

Right-sized RAID storage or cloud retention tiers based on bitrate, frame rate, and required retention days.

Mobile & web clients

Native iOS / Android clients and web consoles with role-based access for operators and investigators.

Power & UPS

Conditioned power and battery backup so cameras stay online during outages.

Integrations

Connects to what you already run.

Our video surveillance systems integrate with your existing identity, communication, and security systems for unified operations.

Deployment Process

How it gets built.

Every project follows the same engineering-led sequence — designed, documented, and delivered with no surprises.

  1. 01

    Site survey

    On-site walkthrough capturing scene geometry, lighting, existing cabling paths, network capacity, and stakeholder requirements.

  2. 02

    Design & PPF mapping

    CAD camera placement with field-of-view overlays, Pixel-Per-Foot targets per scene, and bandwidth / storage calculations.

  3. 03

    Cabling & infrastructure

    Structured cabling, switch staging, VLANs, power, and UPS — installed cleanly and tested before camera deployment.

  4. 04

    Camera install & commissioning

    Cameras mounted, focused, framed, and IP-addressed with consistent naming and calibrated analytics zones.

  5. 05

    VMS configuration

    Recording schedules, retention tiers, motion / analytics rules, role-based user accounts, and alert routing.

  6. 06

    Acceptance & training

    Documented as-built drawings, scene-by-scene image quality validation, and operator + admin training.

Engineering Considerations

What our engineers look for.

  • Lens and resolution are matched to scene-by-scene Pixels-Per-Foot targets — not just by total megapixels.
  • Camera placement honors lighting transitions, sun angles, and obstructions that degrade analytics accuracy.
  • Bandwidth design accounts for both the LAN burst load and any WAN egress to the cloud, with H.265 / smart codecs where supported.
  • Cybersecurity hardening is non-negotiable: dedicated VLAN, no default credentials, signed firmware, and disabled unused services.
  • Retention is sized to the longest applicable requirement (insurance, HIPAA, NDAA, contractual) — not the manufacturer default.
Maintenance & Support

After the install.

Service tiers built around what your facility actually needs — not a one-size-fits-all SLA.

Essentials

Annual on-site preventive maintenance, firmware patching, and remote diagnostics during business hours.

Pro

Quarterly preventive visits, 24/7 remote monitoring of system health, and 4-hour priority response for critical failures.

Managed

Fully managed VMS administration, monthly camera-quality audits, hardware refresh planning, and dedicated technical account manager.

FAQs

Frequently asked.

How many cameras does a typical commercial deployment need?

Camera count is driven by scene coverage, not building size. We design to Pixel-Per-Foot targets for the activities you need to identify (face ID requires more pixels than license plate read or basic activity detection), so an office suite may need 8–12 cameras while a logistics yard may need 60+.

Should we go cloud, on-premise, or hybrid?

Cloud-managed makes sense when you have multiple sites, limited IT staff, and reliable internet. On-premise NVR makes sense when you need long retention, have constrained bandwidth, or operate under air-gap requirements. Hybrid keeps recordings local but pushes management and event clips to the cloud — often the right balance for mid-sized facilities.

Are your cameras NDAA compliant?

We exclusively deploy cameras and NVRs that meet Section 889 of the National Defense Authorization Act for any government, federal contractor, utility, or critical infrastructure project. We can also use NDAA-compliant hardware on commercial deployments at no extra design cost.

How long can footage be retained?

Retention is configurable per camera and per recording stream. Typical commercial retention is 30 days at full quality; 90+ days is common for banking, cannabis, and regulated environments; some clients retain key cameras for 1+ year on cold storage. Storage is sized accordingly in the design phase.

Can existing cameras be integrated?

Yes — most ONVIF-compliant cameras can be brought into a modern VMS. We audit existing fleets during the site survey, identify which cameras meet image-quality and security requirements, and build a phased replacement plan for those that do not.

How does AI video analytics actually help operators?

Modern analytics shift the role from "watch monitors" to "respond to verified events." Edge analytics filter out wind-blown trees, shadows, and animals, and only alert on classified objects (person, vehicle) crossing defined zones. The result: fewer false alerts, faster response, and searchable footage instead of scrubbing through hours of timeline.
