Physical Security Engineering Studio

A complete learning and design environment for physical security professionals. Covers IP video surveillance (CCTV), access control systems, intrusion detection, and integrated security operations — from camera lens calculations and NVR storage sizing to OSDP reader deployments, UL 294 compliance, and ONVIF interoperability standards.

Built for low-voltage systems integrators, electronic security contractors, security consultants, and IT/facilities engineers who design, install, and commission physical security infrastructure for commercial, healthcare, education, and government facilities.

Camera Coverage DesignerLIVE

Calculate field of view, horizontal coverage width, and pixel density at distance for any lens focal length and sensor size. Supports fisheye, varifocal, and PTZ configurations. Outputs a per-camera coverage table and overlap analysis for the full site.

FOVLens CalcPixel Density
Open →
Video Storage Sizing ToolLIVE

Determine total NVR/DVR storage (TB) from camera count, resolution (MP), frame rate, compression codec (H.264/H.265/H.265+), motion-triggered vs. continuous recording, and retention days. Side-by-side codec comparison with storage savings.

NVR SizingH.265Retention
