Security Engineering Tools
Security engineering calculators should be fast, vendor-neutral, and defensible.
These ferramentas help integrators, installers, security managers, and consultants size CCTV systems and supporting infrastructure with clear assumptions—before you commit to hardware.
Recommended workflow (use in this order):
Free Tools
CCTV Storage Calculator for 30-Day NVR Retention
Calculate CCTV storage for 30-day retention, NVR sizing, codec tradeoffs, and commercial camera design review.
IP Camera Bandwidth Calculator for CCTV Networks
Estimate IP camera bandwidth for CCTV networks by camera count, bitrate, codec, frame rate, stream profile, and uplink capacity.
PoE Budget Calculator for Cameras and Switches
Calculate PoE switch budget, cable loss, 802.3af/at/bt headroom, and camera capacity before perimeter security procurement.
Assumptions & Accuracy
"Engineering estimate, not a manufacturer spec. Real-world results vary with scene motion, VBR behavior, lighting changes, analytics, codec implementation, and recording profiles. If you’re doing final procurement, validate using your selected camera/VMS vendor ferramentas and confirm with a pilot config."
Final Check: Always validate with localized scene motion profile and selected VMS overhead calculations.
Common variables that change results fast:
- Motion-heavy scenes (parking lots, roads, crowds)
- VBR peak factor and compression efficiency
- Multi-stream profiles (main + sub + mobile stream)
- Retention policy changes and RAID/filesystem overhead
- Heater/PTZ startup draw and cold-weather load
