Selection notes

Confirm the complete DS-7616NXI-K2/16P(D) model, supplied hardware, selected firmware and camera compatibility before quoting.
ISD confirms supply, price, stock, lead time, hard disks, package contents, accessories and local warranty separately.
IP camera inputs, resolution-specific decoding, synchronous playback and analytics channels are separate limits. Decoding alternatives are not additive simultaneous capacities.
Camera-side analytics require compatible cameras with the selected functions enabled. They are not automatically recorder-side analytics.
All listed AI functions depend on the selected streams and configuration; these references do not establish concurrent use of every function.
The 200 W PoE budget is shared across camera ports, not per-port output. Recorder consumption is specified without HDD and with PoE off, not as the full loaded camera-system demand.
Per-HDD capacity does not establish total usable storage or recording days. Confirm supported drives, bitrate and configuration.
These references apply to DS-7616NXI-K2/16P(D) only.
