Selection notes

• Confirm the complete DS-7616NXI-K2/16P(E) model, supplied hardware, camera compatibility and selected firmware before quoting.
• ISD confirms supply, price, stock, lead time, hard disks, package contents, accessories and local warranty separately.
• IP camera inputs, decoding streams, synchronous playback and analytics channels are different limits. Alternatives in one decoding row are not additive simultaneous capacities.
• Camera-side AcuSearch requires a compatible camera with AcuSearch enabled. Camera-side analytics are not automatically recorder-side analytics.
• The 16 MP recording option is only available for channel 1. Motion detection 2.0 reaches up to 8 MP only with enhanced SVC mode enabled.
• Per-HDD limits do not establish total usable storage or guaranteed recording days. Confirm supported drives, configuration, stream bitrate and scene.
• All listed AI functions are subject to their selected stream and configuration; these sources do not prove concurrent use of every function.
• The 200 W PoE limit is shared across camera ports, not per-port output or recorder input consumption. The recorder consumption row says without HDD, not PoE off; confirm the total camera-system load.
