• Control rooms requiring 4K HDMI display output
• Projects requiring long recording duration with 4 HDD bays
• Rack-mounted CCTV installations
• Projects using separate PoE switches or external camera power
Connect Gates Recommendation:
• Recommended for professional Hikvision smart IP surveillance projects that require AcuSense analytics, facial recognition, ANPR, POS functions, dual Gigabit LAN, and 4 SATA storage expansion.
• Suitable when the project needs advanced event filtering, smart search, smart playback, face database functions, and up to 64TB storage depending on HDD selection.
• Compared with DS-7732NXI-K4, this I4/S model offers stronger advanced analytics options such as POS function, IP speaker support, expanded face comparison options, ANPR attributes, and improved decoding options in selected versions.
• Since this model does not include built-in PoE ports, cameras should be powered using a separate PoE switch or external power source.
