Selection notes

• Confirm the complete DS-7604NXI-K1/4P(E) model, supplied hardware, camera compatibility and selected firmware before quoting.
• ISD confirms supply, stock, price, lead time, hard disks, power accessories, package contents and local warranty separately.
• Camera inputs, decoding streams, synchronous playback and analytics channels are different limits; do not use a decoding figure as the camera-input count.
• Camera-side analytics require a compatible camera, its enabled functions and matching configuration. Listing ONVIF profiles is not universal camera compatibility.
• PoE power is a shared port budget, not per-port output or recorder input consumption. Confirm every camera load, cable and power configuration.
• Disk limits are per HDD; usable storage and recording days depend on supported drives, configuration, codecs, scene and bitrate. No total usable capacity or retention promise is inferred.
• AI capacities depend on the enabled function and stream. The cited E-page does not establish that every listed AI function operates concurrently.
