CHOOSE YOUR SIZE — THREE MODELS ON THIS PAGE

Rule of thumb: count your cameras first — the 9-ch 09B-IQ suits small sites, the 16B-IQ covers mid-size sites, and the 32B-IQ handles parking lots, campuses and multi-building projects. One quirk worth knowing: even on the 32-ch model, local synchronous playback tops out at 16 channels — the other 16 still record and can be viewed live or exported, just not played back side-by-side locally at the same time. Highlighted rows in the spec table below show every other 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.

Small & mid-size sitesThe 9-ch 09B-IQ plus a handful of cameras is a complete kit — one box records, plays back and runs Smart Function for a small site.

Works with your existing camera networkNo built-in PoE here — that means it pairs with any IP camera or PoE switch already on site, instead of locking you into one power scheme.

Large sites needing headroomThe 32-ch 32B-IQ covers parking lots, campuses and multi-building sites — just remember local synchronous playback tops out at 16 channels at a time.

Redundant storageTwo SATA bays with RAID 1 mirroring protect footage from a single disk failure — important for sites that can't afford lost evidence.

Vehicle & people analyticsVehicle Detection (LPR), Motor/Non-Motor Vehicle Search, People Counting and Heat Map turn parking lots and storefronts into searchable, measurable traffic data.

Face-based quick searchFace Detection and Face Comparison feed Face Snapshot Search and Face Comparison Search — investigations that took hours now take minutes.

Not the right pick if you need…

RS232 serial control — this series has RS485 only, no RS232 port
RAID 0/5/6 arrays — the 2-bay Disk Array Type supports RAID 1 mirroring only, not striping or parity RAID
Built-in PoE for cameras — this series has no PoE ports; cameras are powered separately or via an external PoE switch
Full 8-channel Smart AI with third-party cameras — the deepest face/vehicle AI (up to 8-ch) requires Uniview cameras; normal/third-party cameras are limited to 2-ch face detection, 4-ch SIP or 8-ch UMD
4K @ 60Hz output — HDMI tops out at 4K (3840×2160)/30Hz; 60Hz refresh is only available at 1080p and below
