When the as-built is generated from a live model, it is the current state — not an archive. https://siteopscommand.com/blog/cable-paths-by-physics/ https://siteopscommand.com/blog/cable-paths-by-physics/ Mon, 06 Jul 2026 00:00:00 GMT One model & lifecycle Cable length is not a straight line times a fudge factor. Real routes, service loops, and pull tension decide what you buy and whether the pull survives. https://siteopscommand.com/blog/display-sizing-by-the-standard/ https://siteopscommand.com/blog/display-sizing-by-the-standard/ Mon, 06 Jul 2026 00:00:00 GMT Conference AV The back row cannot read a screen too small for the room. AVIXA DISCAS turns can-they-read-it into a distance you compute from the screen and the content. https://siteopscommand.com/blog/glass-is-not-a-wall/ https://siteopscommand.com/blog/glass-is-not-a-wall/ Mon, 06 Jul 2026 00:00:00 GMT Camera & DORI To Wi-Fi, glass is nearly transparent. To a camera, it reflects and refracts. Modeling glass as a plain wall gets both the coverage and the camera view wrong. https://siteopscommand.com/blog/fisheye-and-panoramic-coverage/ https://siteopscommand.com/blog/fisheye-and-panoramic-coverage/ Mon, 06 Jul 2026 00:00:00 GMT Camera & DORI A fisheye lens does not see in a straight line, so a triangular coverage wedge lies about it. How to estimate real coverage for 180 and 360 degree cameras. https://siteopscommand.com/blog/internal-it-and-the-truck-roll/ https://siteopscommand.com/blog/internal-it-and-the-truck-roll/ Mon, 06 Jul 2026 00:00:00 GMT Running the business A corporate IT team owns its buildings but rents its coverage answers: a seat opened twice a year, a trip per complaint. There is another way. https://siteopscommand.com/blog/night-blindness-ir-reach/ https://siteopscommand.com/blog/night-blindness-ir-reach/ Mon, 06 Jul 2026 00:00:00 GMT Camera & DORI A camera that reads faces at noon can go dark at 2 a.m. Its infrared reach is a datasheet number, not a lux rating — design night coverage before you install. https://siteopscommand.com/blog/one-seat-vs-a-shelf-of-tools/ https://siteopscommand.com/blog/one-seat-vs-a-shelf-of-tools/ Mon, 06 Jul 2026 00:00:00 GMT Running the business The tools that make an independent consultant credible were priced for firms. The case for one seat that holds the design, the deliverable, and the bill. https://siteopscommand.com/blog/renewal-starts-at-the-install/ https://siteopscommand.com/blog/renewal-starts-at-the-install/ Mon, 06 Jul 2026 00:00:00 GMT Running the business The install you finish is the renewal you keep next year — if the record stays live. How one model carries design through to renewal without re-keying. https://siteopscommand.com/blog/the-autonomous-site-walk/ https://siteopscommand.com/blog/the-autonomous-site-walk/ Mon, 06 Jul 2026 00:00:00 GMT Virtual site survey Instead of walking a building with a kit, the survey can walk it for you — systematically, and flag the gaps with physics-backed fixes before you visit. https://siteopscommand.com/blog/the-truck-roll-math/ https://siteopscommand.com/blog/the-truck-roll-math/ Mon, 06 Jul 2026 00:00:00 GMT Virtual site survey A predictive design does not need a plane ticket and a $3K kit. Here is the honest math on what a survey trip costs today, and where a visit still earns it. https://siteopscommand.com/blog/wall-material-attenuation-cheat-sheet/ https://siteopscommand.com/blog/wall-material-attenuation-cheat-sheet/ Mon, 06 Jul 2026 00:00:00 GMT Wi-Fi & RF Not all walls cost the same signal. A reference for how much Wi-Fi typical building materials attenuate — drywall to glass to concrete to metal — and why. https://siteopscommand.com/blog/why-conference-room-audio-fails/ https://siteopscommand.com/blog/why-conference-room-audio-fails/ Mon, 06 Jul 2026 00:00:00 GMT Conference AV The microphone gets the blame, but the room is at fault. How reverberation (RT60) and background noise wreck speech intelligibility — and what fixes it. https://siteopscommand.com/blog/your-bom-is-the-design/ https://siteopscommand.com/blog/your-bom-is-the-design/ Mon, 06 Jul 2026 00:00:00 GMT One model & lifecycle A bill of materials keyed by hand drifts from the drawing the moment one of them changes. When the BOM is generated from what you placed on the plan, it cannot. https://siteopscommand.com/blog/how-to-run-a-virtual-site-survey/ https://siteopscommand.com/blog/how-to-run-a-virtual-site-survey/ Sun, 05 Jul 2026 00:00:00 GMT Virtual site survey The survey that once needed a plane ticket and a hardware kit can start from your floor plan. Here is the virtual site survey workflow, step by step. https://siteopscommand.com/blog/ppf-is-the-floor/ https://siteopscommand.com/blog/ppf-is-the-floor/ Sun, 05 Jul 2026 00:00:00 GMT Camera & DORI A pixels-per-foot number draws a clean wedge on a flat plan. Fisheye lenses, night IR, and shadows from walls and racking are where camera coverage breaks. https://siteopscommand.com/blog/scoring-a-conference-room/ https://siteopscommand.com/blog/scoring-a-conference-room/ Sun, 05 Jul 2026 00:00:00 GMT Conference AV Conference-room AV is not a matter of taste: AVIXA DISCAS, IEC 60268-16 STI, and mic polar patterns score every seat for sightline, sound, and pickup. https://siteopscommand.com/blog/the-cost-of-six-spatial-models/ https://siteopscommand.com/blog/the-cost-of-six-spatial-models/ Sun, 05 Jul 2026 00:00:00 GMT One model & lifecycle The nearest thing to one platform is six tools stitched together: Ekahau, IPVM, EASE, System Surveyor, ConnectWise, DocuSign. Here is what the seams cost you. https://siteopscommand.com/blog/predictive-vs-measured-wifi-surveys/ https://siteopscommand.com/blog/predictive-vs-measured-wifi-surveys/ Sun, 05 Jul 2026 00:00:00 GMT Wi-Fi & RF Predictive and measured Wi-Fi surveys answer different questions. Here is what each one is for, when to spend the effort, and how a calibrated model uses both. https://siteopscommand.com/blog/warehouse-wifi-racking/ https://siteopscommand.com/blog/warehouse-wifi-racking/ Sun, 05 Jul 2026 00:00:00 GMT Wi-Fi & RF Most predictive tools treat a warehouse like an empty box. Steel racking attenuates Wi-Fi by depth and angle — why aisles go dead, and how to model it. https://siteopscommand.com/blog/what-dori-means-for-cameras/ https://siteopscommand.com/blog/what-dori-means-for-cameras/ Sun, 05 Jul 2026 00:00:00 GMT Camera & DORI DORI (IEC 62676-4) grades camera coverage in pixels per metre: Detect, Observe, Recognize, Identify. What each tier needs, and why one PPF number fails. https://siteopscommand.com/blog/wi-fi-heatmap-without-ekahau/ https://siteopscommand.com/blog/wi-fi-heatmap-without-ekahau/ Sun, 05 Jul 2026 00:00:00 GMT Wi-Fi & RF You do not need a subscription and a hardware kit for a predictive Wi-Fi heatmap — here is how a computed one works, and where measuring on site still counts. https://siteopscommand.com/blog/wifi-heatmap-itu-r-standards/ https://siteopscommand.com/blog/wifi-heatmap-itu-r-standards/ Sun, 05 Jul 2026 00:00:00 GMT Wi-Fi & RF A predictive Wi-Fi heatmap is only as honest as its physics. Here is what ITU-R P.2040, P.526, and P.1238 model, and why the more conservative answer wins. https://siteopscommand.com/blog/introducing-siteops-command/ https://siteopscommand.com/blog/introducing-siteops-command/ Thu, 02 Jul 2026 00:00:00 GMT Product & field notes One operating picture for integrators: survey and design in 2D/3D, generate the deliverables, run the project, and keep the renewal. All on one model.
