It ships with two fixed lens options: 2.8 mm (ASF28K, 97.0° wide view) or 4.0 mm (ASF40K, 79.0° longer-reach view). It has a built-in microphone with audio detection, supports microSD edge storage up to 512 GB, uses Ultra 265 compression to reduce NVR bandwidth, and is NDAA compliant.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shops & storefronts4MP detail plus a built-in mic with audio detection can flag raised voices at the counter. ASF28K's 97.0° view covers the whole shop floor from a corner.
Home gates & drivewaysSmart IR sees up to 30 m at night in black & white. ASF40K's narrower 79.0° view watches the full length of a gate or driveway.
Warehouse & site perimetersIP67 body and −30 °C to 60 °C rating survive rain, dust and heat. The microSD slot (up to 512 GB) keeps footage even if the network link to the NVR drops.
Government & critical-infrastructure projectsThe camera is NDAA compliant, relevant for procurement that requires equipment from non-restricted sources.
Small offices & multi-camera sitesUltra 265 compression and dual video streams keep bandwidth and NVR storage use low across many cameras.
Network-security-conscious deploymentsHTTPS encryption, RTSP/HTTP/ONVIF authentication, ARP protection and watermarking harden the camera against common network attacks.
Not the right pick if you need…
- Two-way talk — it has a mic but no speaker
- Wi-Fi — this is a wired RJ45 camera
- Zoom — the lens is fixed (2.8 or 4.0 mm, chosen at purchase)
- Color night vision — this camera has Smart IR (black & white) only, no warm-light illuminator
- Alarm in/out wiring for sirens or sensors

IR MODE
Invisible infrared — discreet black & white night vision
Smart IR up to 30 m (98.4 ft.) at 850 nm. The camera watches without lighting up the scene — nothing shows it is recording. This model has Smart IR only; there is no warm-light illuminator.

How wide a view at each distance
Scene width covered at typical mounting distances — the number you need to work out how many cameras a wall, yard or aisle takes.
| Distance | K · 97.0° | K · 79.0° |
|---|---|---|

Calculated from the horizontal field of view in the specifications below: width = 2 × distance × tan(FOV ÷ 2). Lens distortion and mounting angle are not included.
Who uses it, where it goes and how to install it
Written for the IPC2124LB-ASF28(40)K-A from its own specifications: 4 MP, 2.8 mm or 4.0 mm fixed lens, 30 m Smart IR, built-in mic with microSD, PoE at max. 5.0 W.
Who it is for
- Security installers and integrators — One 802.3af PoE cable per camera at max. 5.0 W, ONVIF Profile S/T for Uniview or third-party NVRs, and Ultra 265 to keep NVR bandwidth low.
- Shops and small offices — The 2.8 mm version sees 97.0° wide, enough for a sales floor from one corner; the built-in mic records sound and audio detection can raise an alarm on loud noise.
- Homes, gates and driveways — The 4.0 mm version identifies a face up to 9.0 m away, and Smart IR keeps the gate visible in black and white up to 30 m at night.
- Remote sites and small perimeters — IP67 body for −30 °C to 60 °C, and a microSD slot up to 512 GB so a single camera can record on its own where there is no NVR.
- Projects that require NDAA — The page lists this camera as NDAA compliant, which matters for tenders and buyers that exclude restricted sources.
Where and how to install
- Height and angle — Mount at about 2.5–3.5 m with a shallow downward tilt. Lower is easy to tamper with; much higher shows the top of heads instead of faces.
- Faces need a choke point — Aim at a door, gate or corridor where people walk toward the camera, within the identify distance: 6.3 m with the 2.8 mm lens, 9.0 m with the 4.0 mm lens.
- Keep the IR path clear — At night the 850 nm IR reflects off eaves, walls, gutters or branches close to the lens and turns the picture white. Keep these out of the frame and use the sun shield as fitted.
- Backlight needs careful placement — This model has digital WDR (DWDR) plus HLC and BLC, not a wide 120 dB WDR. Do not aim it from inside out through a glass door or at headlights; place it so the bright area is to the side, or light the subject's side.
- Brackets and junction box — Hide the RJ45 and 12 V tail in the TR-JB05-A-IN junction box with the TR-A01-IN cable gland. Pole: TR-UP06-B-IN, or TR-UP06-C-IN-V2 with the junction box. Building corner: TR-UC08-C-V2.
- Weather and surge — The body is IP67 for −30 °C to 60 °C, but water still enters through an unprotected cable joint. Surge protection is 4 kV; on poles or long outdoor runs add a network surge protector and earthing.
2.8 mm or 4.0 mm: what you actually see
Same 4 MP sensor, different lens. The 4.0 mm reaches about 1.4× farther for the same detail but covers about a quarter less width. At 10 m it puts about 155 pixels on every meter of the scene versus about 113 for the 2.8 mm.
| ASF28K · 2.8 mm | ASF40K · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 97.0° | 79.0° |
| Width covered at 5 m | 11.3 m | 8.2 m |
| Width covered at 10 m | 22.6 m | 16.5 m |
| Pixels per meter at 10 m | ≈113 px/m | ≈155 px/m |
| Identify a stranger's face up to | 6.3 m | 9.0 m |
| Recognize someone you know up to | 12.6 m | 18.0 m |
| Detect that something is there up to | 63.0 m | 90.0 m |
- Pick 2.8 mm for a shop floor, a small yard or a room seen from a corner: from 5 m away it covers 11.3 m of width.
- Pick 4.0 mm for a gate, driveway or corridor where faces matter at 7–9 m: identification still works at 9.0 m.
- Night limit is the same for both: Smart IR lights the scene up to 30 m, so detail beyond that is lost after dark whatever the lens.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 2560 ÷ width at 10 m; face distances are the manufacturer's DORI figures.

4MP PoE IP Camera FAQ — IPC2124LB-ASF28(40)K-A
What night vision range does the IPC2124LB-ASF28(40)K-A give?
Smart IR reaches up to 30 m (98.4 ft) at 850 nm — invisible light that does not reveal the camera at night. Images switch to black and white via the IR-cut filter, the camera works at 0 lux with IR on, and LED power self-adjusts to avoid over-exposing close subjects.
Does it have local storage and audio recording?
Yes. The camera offers microSD edge storage, so video keeps recording on the card even if the link to your NVR drops, and a built-in microphone adds sound with G.711U/G.711A compression at 64 Kbps. Audio detection can also trigger alarms on unusual noise.
Which lens version fits my site, 2.8 mm or 4.0 mm?
The 2.8 mm (ASF28K) covers 97° horizontally and detects people to 63 m, identifying at 6.3 m — take it for entrances and rooms. The 4.0 mm (ASF40K) narrows to 79° but detects to 90 m and identifies at 9 m — better for corridors, fences and driveways.
Is this camera acceptable for NDAA-restricted projects?
Yes, the IPC2124LB-ASF28(40)K-A is NDAA compliant, which matters for tenders that exclude restricted vendors. It also ships hardening features that auditors ask about: strong password enforcement, RTSP and user authentication, IP address filtering, ARP protection and watermarking of footage.
What video quality and bandwidth should I plan for?
Plan around 4 MP (2560×1440) at up to 25 fps on the main stream, with bit rate set anywhere between 128 Kbps and 6144 Kbps. Ultra 265 with U-code on the main stream keeps real-world bandwidth low, and the sub stream serves phones and slow links.
Will the IPC2124LB-ASF28(40)K-A work with a Hikvision, Dahua or other non-Uniview NVR?
Usually yes for live view and recording: it supports ONVIF Profile S and T plus RTSP. Profile G is not listed, so playing back the microSD card through a third-party NVR is not expected to work; motion and audio alarms may also be limited on other brands. Tell us your NVR model and we will confirm before you order.
What PoE switch and cable do I need for the IPC2124LB-ASF28(40)K-A?
Any IEEE 802.3af (or 802.3at) PoE port works: the camera draws at most 5.0 W, so 8 cameras need only about 40 W of PoE budget in total. Its network port is 10/100 Mbps, so Fast Ethernet PoE ports are enough; with many cameras use a gigabit uplink to the NVR (16 cameras at the 6144 Kbps maximum add up to about 98 Mbps). Use Cat5e or Cat6 copper cable up to 100 m per run, or a 12 V DC adapter with a Ø5.5 mm plug where there is no PoE.
How much NVR hard-disk space do I need for the IPC2124LB-ASF28(40)K-A?
At the maximum bit rate of 6144 Kbps with continuous recording, one camera writes about 66.4 GB per day, or about 2 TB for 30 days. Assuming a more typical 4096 Kbps, 8 cameras need about 10.6 TB for 30 days of continuous recording. Ultra 265 at a lower bit rate, or recording only on events, cuts this sharply.
Will the IPC2124LB-ASF28(40)K-A send false alarms from trees, rain or animals?
It can, because its events are plain motion detection, tampering alarm and audio detection; human or vehicle classification is not listed. Draw the motion area only over the path or door, lower the sensitivity, keep moving branches and road traffic out of the frame, and keep the IR area free of spider webs. If you need alarms only on people, ask us for a model with human-body-based detection, such as the IPC2124LB-ADF28(40)KM-H.
Can the IPC2124LB-ASF28(40)K-A see faces against a bright doorway or glass shop front?
Only partly: it has digital WDR (DWDR), BLC and HLC, which brighten a dark face or tame headlights, but it is not a 120 dB WDR camera. Mounted inside looking out at a sunny street, faces will often be dark silhouettes. Mount it outside facing in, or at an angle so the daylight is not behind the person; if the view must face strong light, choose a model with a stated 120 dB WDR.
