Storage, bandwidth, PoE budget and lens calculations for quoting commercial camera systems correctly the first time.
Calculate PoE at the documented source boundary, with peak/startup demand, cable losses, actual allocation and source variant. Distinguish load-plus margin from unallocated capacity and retain real tests.
Budget actual recorder input/output, interface directions, shared network/WAN and concurrent client/processing demands. Separate assumed rates and margin arithmetic from measured full-workload approval.
Plan PoE distance from the complete data and power link. Compare the100 m channel, documented extend mode, specified extenders, fiber and remote-power options.
Calculate camera-storage payload from actual bitrates and recording time, then confirm usable capacity, compatible drives, NVR limits and real retained footage.
