Most system failures come from the same root causes. Match your situation to the right guide.
Engineering Guides
Each guide addresses a specific design domain. Most projects need 2-4.
IP Camera Selection & Deployment
Choose the right camera class for each zone based on evidence intent, environment, and operational constraints.
- Camera roles by zone type
- Mounting height & angle guidelines
- Lens selection by target distance
Retention Modeling & Storage Sizing
Model retention as a predictable outcome of bitrate, recording mode, motion levels, and camera count.
- Bitrate modeling per profile
- Recording mode comparison
- Storage sizing calculator
Network & PoE Planning
Validate PoE budgets, switching capacity, uplinks, and segmentation so the system holds load.
- PoE budget validation
- VLAN segmentation approach
- Bandwidth headroom check
Video Recording Platforms
Compare NVR appliances, hybrid systems, and software-based platforms by scale, features, and retention.
- NVR vs VMS comparison
- RAID & redundancy planning
- License model evaluation
Lens & Coverage Geometry
Define identification zones, validate pixel density on target, and select lenses for specific outcomes.
- FoV vs identification distance
- Pixel density requirements
- Varifocal vs fixed selection
VMS Selection & Architecture
Evaluate VMS platforms by feature set, scalability, analytics integration, and operational workflows.
- Feature matrix comparison
- Scalability architecture
- Analytics integration paths
LPR System Design
Engineer license plate capture as a controlled system: shutter, angle, distance, plate fill, and illumination.
- Capture zone geometry
- Shutter & IR illumination
- Integration with access control
Thermal Camera Deployment
Deploy thermal for perimeter detection where visible cameras fail: darkness, weather, and long-range scenarios.
- Detection range modeling
- Thermal vs visible pairing
- Analytics integration
Radar-Based Video Detection
Separate real movement from pixel noise using radar to eliminate false alarms from weather and lighting.
- Radar vs VMD comparison
- Zone configuration
- Integration with VMS alerts
PTZ Deployment & Guard Tours
Configure PTZ cameras with presets, guard tours, and auto-tracking for active monitoring workflows.
- Preset & tour configuration
- Auto-tracking setup
- Operator workflow design
Body-Worn Camera Policy & Storage
Build BWC programs with retention policy, chain of custody, storage architecture, and officer workflows.
- Retention policy framework
- Chain of custody procedures
- Cloud vs on-prem storage
People Counting & Analytics Accuracy
Validate counting accuracy by environment: ceiling height, zone type, camera placement, and lighting.
- Accuracy benchmarking
- Environment suitability scoring
- Integration with BI systems
Engineering Calculators and Self-Assessments
Interactive tools to create decision confidence. Each links to the service page where the calculator lives.
