Applications:
• 32-camera IP CCTV systems
• Medium and large commercial surveillance projects
• Factories and industrial facilities
• Warehouses and logistics sites
• Schools, universities, and administrative buildings
• Hospitals, clinics, and medical facilities
• Retail branches and large showrooms
• Residential compounds and large villas
• Sites requiring long recording duration up to 40TB storage
• Systems requiring dual LAN, alarm I/O, and serial interface integration
• Projects requiring smart functions such as ANPR, heat map, and people counting
• Professional CCTV control rooms and rack-mounted installations
Connect Gates Recommendation:
• Recommended for professional Hikvision IP surveillance projects requiring up to 32 channels, 4 HDD bays, dual Gigabit LAN, alarm I/O, and independent HDMI/VGA monitoring.
• Suitable when the customer needs longer recording duration, higher camera capacity, and more professional integration options than standard 1U 2-SATA NVR models.
• Compared with 32-channel 2-SATA models, this model is stronger for storage-heavy projects because it supports 4 HDDs with up to 40TB total capacity.
• Since this model does not include built-in PoE ports, cameras should be powered using a separate PoE switch or external power source.
