Selection notes

• The documented specifications apply to the cited manufacturer version. Confirm the supplied hardware, firmware and accessory configuration.
• Specifications follow Hikvision exact (C) manufacturer datasheet, 2024-08-06. Exact original model and hardware suffix retained. Confirm supplied regional unit and accessories. PCM appears in only one of two duplicate audio-decoding rows; no PCM support asserted for this edition. Manufacturer prints 1.5 layers at 4K without explaining a fractional-window allocation. No rounded or per-port 4K layer capacity inferred. The aggregate formula depends on the undefined 1.5-layer 4K allocation, so no total layer count is calculated or published. The labelled W/H/D tuple places the long enclosure depth in the height position relative to the product drawing. No axis swap or dimensions from another revision substituted. Feature list states 64 scenes while specification table states 1; capacity withheld. Row is labelled audio input but describes audio output, including DB15 that is absent from this unit. No input interface inferred. Source lists audio encoding despite no video input interfaces and no reliable audio-input description. Encoding support withheld pending exact input confirmation. No local video input is present; the 120 ms local-source delay row has unresolved applicability. The 2024-08-06 packing list includes a power cord but does not explicitly include an external 12 VDC adapter; newer editions are not substituted. Frame-synchronization marketing text does not establish zero latency; the explicitly listed delay values are retained where applicable.
• Readers, locks, power supplies, batteries, licences and other accessories are not assumed to be included. ISD confirms specification, compatibility, supply, price, lead time and local warranty separately.
