16 / 32 / 64-channel network video recorder — four SATA bays with RAID 0/1/5 support for redundant storage, Ultra 265 compression, dual independent 4K HDMI/VGA output, records cameras up to 32MP, with onboard Face Detection, Vehicle Detection (LPR) and AI smart search.

CHOOSE YOUR SIZE — THREE MODELS ON THIS PAGE

Rule of thumb: count your cameras across the whole site, then leave room to grow — 16 channels covers a single building; step up to the 32E-IQ or 64E-IQ if you're combining several buildings, a large campus, or expect to add cameras later. Highlighted rows in the spec table below show every difference between the three.

Is this the right recorder for you?

Plain-language guide for buyers and installers — based only on what this recorder actually does.

Large sites & multi-building campuses16, 32 or 64 channels in one box covers a full warehouse, factory floor, or multi-building campus without stacking multiple recorders.

Uptime-critical storageDisk Group and Redundant Storage with RAID 0, 1 or 5 across the four bays mean a single failed drive doesn't take the recording offline — built for sites where continuous coverage matters.

Two independent monitor outputsHDMI1+VGA1 and HDMI2+VGA2 run as two separate output pairs at the same time — put the full wall on one screen and a secondary control view on another, without extra hardware.

Growing camera countsBuy channels you don't use yet: the 32E-IQ or 64E-IQ lets you add cameras later without replacing the recorder.

Remote viewing on phoneP2P protocol built in — the manager checks every site from a phone app without a fixed IP or network skills.

Local-language interface38 GUI languages including Spanish (Latin America), Portuguese (Brazil) and French — your customer operates it in their own language.

Quick incident lookup across many channelsBuilt-in Face Detection, Vehicle Detection (LPR) and Temperature Detection feed AcuSearch, AcuTrack and Face Snapshot Search — jump straight to the clip you need instead of scrubbing hours of footage across up to 64 channels.

Not the right pick if you need…

PoE ports — cameras need a separate PoE switch (this recorder has no built-in PoE ports)
A fifth hard disk or more — this series tops out at 4 SATA bays (up to 96 TB total with four 24 TB drives)
RAID 6 or RAID 10 — the Disk Array Type on this series supports RAID 0, 1 and 5 only
A single unified 4-way display — HDMI1/VGA1 and HDMI2/VGA2 are two independent output pairs, not four synced views of one layout
DC-only power sites — this recorder runs on AC 100–240V mains, with no DC input option
