The Uniview IPC2122LE-ADF28(40)KMC-DL is a 2MP fixed mini bullet network camera from the ColorHunter dual-light line. It combines 30 m infrared and 30 m warm-light illumination for discreet black-and-white or full-color night vision, powers over a single PoE cable, and carries an IP67 outdoor rating (−30 °C to 60 °C) with a built-in mic and speaker for two-way audio. It is offered with two fixed lenses: 2.8 mm (ADF28KMC, wider view) or 4.0 mm (ADF40KMC, longer reach).
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Shops & storefrontsColorHunter keeps faces and colors visible after dark, and the built-in speaker lets you greet customers or warn off loiterers remotely.
Home gates & yardsWarm light switches on automatically at night — visitors are seen in full color, and intruders know the camera is watching.
Corridors & loading docks9:16 corridor mode fits narrow passages without wasted frame, and the IP67 body handles outdoor loading areas in rain or dust.
Residential compoundsCross-line and intrusion alerts are based on human body detection, so they trigger for people — not for cats or blowing leaves.
Small offices & receptionBuilt-in mic and speaker turn the camera into a two-way intercom — answer a visitor at the door without leaving your desk.
Kiosks & fuel stationsOne PoE cable handles power and video, and footage can go to a microSD card, an NVR, or NAS — whichever fits the site.
Not the right pick if you need…
- Optical zoom — the lens is fixed (2.8 or 4.0 mm, chosen at purchase)
- Wi-Fi — this is a wired RJ45 camera
- Alarm in/out wiring for sirens or sensors
- Analog (CVBS) video output — this is an IP-only camera
- Motorized pan-tilt — mount adjustment is manual 3-axis only

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.
WARM LIGHT MODE
Visible warm light — full-time color and active deterrence
Warm white light up to 30 m (98.4 ft.) keeps faces and clothing colors visible at night — and tells intruders the area is watched.

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.

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 IPC2122LE-ADF28(40)KMC-DL from its own specifications: 2 MP, 2.8 mm or 4.0 mm F1.6 fixed lens, dual light (30 m IR + 30 m warm light), 120 dB true WDR, mic and speaker, PoE.
Who it is for
- Shops, kiosks and fuel stations — Two-way audio lets the owner speak to customers or loiterers from the app, and warm light gives color video of faces and clothing at night.
- Gates and entrances facing bright light — 120 dB true WDR keeps faces readable against daylight or glass, and the speaker lets you answer a visitor at the gate like an intercom.
- Residential compounds and yards — Cross line and intrusion alarms are based on human body detection, so cats and moving leaves cause fewer false alarms; the IP67 body works from −30 °C to 60 °C.
- Corridors, loading docks and installers — 9:16 corridor mode for narrow spaces, recording to microSD up to 512 GB, an NVR or NAS (NFS), ONVIF Profile S/G/T, and a 4-language web interface (English, Russian, Spanish, Vietnamese).
Where and how to install
- Height for talking and faces — Mount at about 2.5–3 m near the door or gate so the speaker and mic are close enough for a conversation and the tilt stays shallow; much higher shows the top of heads and makes the voice hard to hear.
- Faces need a choke point — Aim at a door or gate where people walk toward the camera, within the identify distance: 4.3 m with the 2.8 mm lens, 6.2 m with the 4.0 mm lens.
- Keep the light path clear — Do not mount tight under eaves, beside a wall that is in the picture, or behind glass: both the IR and the warm light reflect back and wash out the image. Do not aim the 30 m warm light at a neighbor's windows.
- Keep the speaker sheltered from noise — Avoid mounting next to generators, air-conditioner units or busy roads: the mic picks up the noise, audio detection triggers falsely and two-way talk becomes hard to understand.
- Weather, cable and surge — The body is IP67, but the RJ45 and 12 V tail are not: put them in the TR-JB05-B-IN junction box and seal the conduit entry with the TR-A01-IN NPT 3/4" gland. Surge protection is 4 kV; on poles or long outdoor runs add a surge protector and earthing.
- Brackets and corridors — Pole: TR-UP06-C-IN-V2, which fits the junction box only, so order it together with TR-JB05-B-IN; building corner: TR-UC08-C-V2. For hallways, turn the camera 90° and use the 9:16 corridor mode.
2.8 mm or 4.0 mm: what you actually see
Same 2 MP sensor, different lens. The 4.0 mm sees about 1.4× farther (identify 6.2 m vs 4.3 m) but covers about 70% of the width. At 10 m it puts about 100 pixels on every meter of the scene versus about 71 for the 2.8 mm. At night both are limited by the 30 m light range.
| ADF28KMC · 2.8 mm | ADF40KMC · 4.0 mm | |
|---|---|---|
| Horizontal view angle | 106.7° | 87.5° |
| Width covered at 5 m | 13.4 m | 9.6 m |
| Width covered at 10 m | 26.9 m | 19.1 m |
| Pixels per meter at 10 m | 71 | 100 |
| Identify a stranger's face up to | 4.3 m | 6.2 m |
| Recognize someone you know up to | 8.7 m | 12.4 m |
| Detect that something is there up to (daytime) | 43.4 m | 62.1 m |
| IR / warm light range at night | 30 m | 30 m |
- Pick 2.8 mm for a shop front, porch or small yard: from 5 m away it covers 13.4 m of width.
- Pick 4.0 mm for a gate or driveway where faces matter at 5–6 m: it identifies a face at 6.2 m.
- If you will use two-way audio, choose the spot for talking first (close to the door), then the lens: from 3 m away the 2.8 mm still covers about 8 m of width.
Widths are calculated from the horizontal view angle (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 1920 ÷ width at 10 m; face and detect distances are the manufacturer's DORI figures.

2MP Dual-Light Camera FAQ — IPC2122LE-ADF28(40)KMC-DL
Can this camera show color images at night?
Yes. This ColorHunter model carries dual illuminators: warm white light up to 30 m keeps faces and clothing colors visible at night, or you can switch to invisible 850 nm IR, also 30 m, for discreet black-and-white monitoring. Control is Auto or Manual.
Can I talk to visitors through the camera?
Yes. It has a built-in microphone and speaker with full two-way audio support, using G.711U/G.711A compression at 64 Kbps. From the monitoring side you can hear the scene and speak back — useful for gate control, delivery instructions or warning off loiterers.
Does it detect people crossing a fence line?
Yes. Detection includes cross-line and intrusion events based on human body detection, plus motion detection, ultra motion detection, tampering alarm and audio detection. Human-based filtering means moving branches or stray animals trigger far fewer false alarms than plain motion detection.
Which lens option covers my site better, 2.8 mm or 4.0 mm?
The 2.8 mm sees 106.7° horizontally and detects people to 43.4 m — good for doorways and courtyards. The 4.0 mm narrows to 87.5° and stretches detection to 62.1 m, with identification at 6.2 m versus 4.3 m. Both share the same F1.6 aperture and 0.003 lux sensitivity.
How does it handle strong backlight at a gate facing the sun?
It uses 120 dB WDR to balance a bright street behind a dark entrance, backed by HLC against headlights, BLC, digital defog and 2D/3D noise reduction. Minimum illumination is 0.003 lux in color at F1.6, so dusk and poorly lit streets stay usable.
How do I power and install it outdoors?
Power comes over PoE, so one Cat5e/Cat6 run from your PoE switch carries video, audio and power together. The IP67 housing is rated for rain and dust, and the mount adjusts pan 0–360°, tilt 0–90° and rotate 0–360°, covering wall and pole positions.
Will two-way audio and smart alarms of the IPC2122LE-ADF28(40)KMC-DL work on a Hikvision, Dahua or other non-Uniview NVR?
Video almost always works: the camera supports ONVIF Profile S, G and T plus RTSP. Two-way talk, the human-body-based cross line and intrusion alarms and the IR/warm light setting are fully supported on Uniview NVRs; on other brands they may be missing or show only as plain motion, so you may need to set the light mode in the camera's own web page. If talk-back through the NVR app matters, tell us your NVR model and we will confirm before you order.
Does the speaker change the PoE power needed for the IPC2122LE-ADF28(40)KMC-DL?
The listed maximum is 4.4 W without the speaker; the figure with the speaker playing is not given, so leave margin. An IEEE 802.3af port supplies up to 15.4 W at the switch, which covers one camera comfortably, but when you size the switch's total PoE budget, count more than 4.4 W per camera for sites that use talk-back or alarm sound often. Keep Cat5e/Cat6 copper runs within 100 m.
How many days of recording fit on microSD, an NVR or a NAS with the IPC2122LE-ADF28(40)KMC-DL?
At the maximum bit rate of 6144 Kbps with continuous recording it writes about 66.4 GB per day: about 7.7 days on the maximum 512 GB card and about 2 TB per camera for 30 days on an NVR or NAS. At 2048 Kbps with Ultra 265 the same card lasts about 23 days. With ANR, a microSD card also fills the gap if the link to the NVR drops, so a card is worth fitting even when you record on an NVR.
IPC2122LE-ADF28(40)KMC-DL or IPC2122LB-AF28(40)K-DL: what does the extra get me?
Both are 2 MP dual-light bullets with 30 m IR and 30 m warm light. This model adds a built-in speaker for two-way audio, 120 dB true WDR, cross line and intrusion based on human body detection, 9:16 corridor mode, tampering alarm and NAS recording. It is also larger: 192 × 75 × 74 mm and 0.40 kg. Choose it for entrances where you want to talk to visitors or face bright backlight.
Will the warm light on the IPC2122LE-ADF28(40)KMC-DL attract insects and cause false alarms?
Any light next to a lens draws some insects at night, and spiders then build webs in front of it. Reduce false alerts by using cross line or intrusion (based on human body detection) or Ultra motion detection instead of plain motion detection, and by using IR mode where color at night is not needed. Keep the camera away from other lamps and clean the front glass and web anchors during maintenance.
What if I forget the password of the IPC2122LE-ADF28(40)KMC-DL?
This model has a physical reset button, so it can be returned to factory defaults on site; you then set a new strong password and redo the settings (IP address, light mode, alarms). Because a reset means reaching the camera, save the password for the installer and give the owner a separate common-user account: up to 32 users can be created.
