Storage, bandwidth, PoE budget and lens calculations for quoting commercial camera systems correctly the first time.
Identify the real recorder limit before choosing an external switch or larger NVR. Verify reusable infrastructure, complete workload, old-footage preservation and secure owner/client migration.
Count the recorded views the business needs and verify them on the survey. Use explicit early-budget assumptions, then size camera streams, recorder resources, power, storage and agreed growth separately.
Separate connection and viewing-performance faults, then trial supported streams against the actual client task and full network/recorder workload. Keep payload estimates distinct from measured results and preserve local recording quality.
Compare central and per-building recording using actual link capacity, power, storage, outage behavior and supported client workflows. Include complete costs and recorded acceptance tests.
Plan camera cable routes using the actual permanent-link, channel or MPTL design, cords, temperature and peak PoE. Assess remote cabinets, fiber and documented extensions with real test results.
Use exact model field of view and recording resolution to estimate scene width and density. Generic lens-chart assumptions and historical DORI values do not guarantee identification; verify current requirements and actual recordings.
Compare 4MP, 5MP and 8MP by exact field of view, delivered recording mode, motion and night tests. Keep illustrative bitrate/storage arithmetic separate from measured workload and identification claims.
Verify actual channels/views, integrated and external power, input/output data, formats, decoding, AI and usable retention. Recorder and PoE counts are separate; supported complete-workload tests set the final camera capacity.
Calculate scene width and density using exact field of view and delivered pixels, with assumptions clearly marked. Separate historical DORI guides from current requirements and verify actual mounted recordings.
Choose H.264, H.265 or S+265 by the actual supported recording, client and export workflow. Verify moving detail and measured rates; no fixed half-bitrate or headline storage saving is guaranteed.
