Maintain substantial local video retention with a rack-based NVR configured around eight 18 TB hard drives. This IQSIGHT recorder provides 144 TB of raw storage capacity in a 2U chassis, concentrating high-capacity recording storage into two rack units. The configuration suits security environments where retention capacity must be established at the recorder rather than added later through an external storage platform. The eight-drive configuration gives administrators a defined storage layout for video archives. Eight 18 TB disks provide the recorded-media capacity associated with this unit, while the 2U form factor helps reserve rack space for network, power, and security infrastructure. Its density is relevant where a surveillance rack must accommodate multiple system components without consuming a large vertical footprint. IQSIGHT DIP-74CIS8HDMR-POS identifies the specific 2U, eight-drive, 18 TB-per-drive configuration. It differs through its fixed 144 TB raw storage arrangement rather than an unspecified disk population or capacity. Match the recorder’s 2U rack allocation and storage requirement to the site’s retention target before installation. Camera-channel limits, recording resolution, power details, and connectivity are not asserted here.
