The Uniarch Uho-S3S-M33D puts two independent 3MP lenses on one indoor Wi-Fi camera body, sharing a single IP address and a single USB-C power connection. The fixed Panorama lens (91.5° view) keeps the whole room in frame at all times, while the motorized Detail lens (355° pan, -15°~90° tilt, 4X digital zoom) moves in to check on a person, pet or object without ever losing the wide view. It adds human/vehicle/pet classification, crying detection, two-way audio, IR + warm-light night vision to 10m and MicroSD storage up to 512GB, powered by USB-C (DC 5V/1.5A) with either 2.4GHz Wi-Fi or a wired Ethernet port for the network connection.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
Living rooms & nurseriesPanorama keeps the whole room in view all the time; when something needs a closer look — is the baby's face clear, is the stove really off — swing Detail over and zoom 4X without ever losing the wide shot.
Small shops & reception countersPanorama covers the whole counter and doorway; Detail pans over to follow one specific customer or zoom in on the register, all from a single camera and a single app.
Pet ownersPet detection tells a cat or dog apart from a person, and warm-light night vision shows their real colors after dark instead of black-and-white IR.
Fewer false phone alertsUltra motion detection classifies human, vehicle and pet separately, and crying detection flags a baby's cry specifically — so notifications point to what actually matters.
Local backup you controlMicroSD edge storage up to 512GB keeps footage from both lenses on the camera itself — no monthly cloud subscription required to have a recording.
Quick DIY installsNo electrician or cable-puller needed — set it on a shelf or mount it, plug in the USB-C power, and connect to Wi-Fi from the app in a few minutes.
Not the right pick if you need…
- Outdoor use — this is an indoor camera with no IP-rated body, working range is -10°C to 50°C
- Continuous 360° rotation — the Detail lens pans up to 355° (not a full circle) and the Panorama lens does not move at all, it is fixed
- True optical zoom — Detail's 4X zoom is digital, not optical; Panorama has no zoom at all
- ONVIF or third-party NVR integration — this camera's integration path is its own API/SDK and the Uniarch app/client, not a listed ONVIF profile
- PoE power — there is no PoE port, power comes only from the included USB-C DC 5V/1.5A supply

Night vision: infrared + warm light
Both illuminators live on the Detail lens — switch Auto/Manual per site. The fixed Panorama lens has no illuminator of its own.
IR MODE
Invisible infrared — discreet black & white night vision
IR illumination up to 10 m (32.8 ft.) at 850nm on the Detail lens. The camera watches without lighting up the room — nothing shows it is recording.
WARM LIGHT MODE
Full-color night vision with warm light
Warm-light illumination up to 10 m (32.8 ft.) on the Detail lens keeps video in full color after dark. Switch back to IR-only whenever discretion matters more than color.
How far can it see? (DORI)
DORI (EN 62676-4) is the industry standard for what a camera can do at distance.
Uniview's own datasheet publishes DORI distances only for the motorized Detail lens (4.0mm) — the fixed Panorama lens does not have a separately rated DORI figure in the manufacturer's specification table.

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 | 91.5° |
|---|---|
| 5 m16 ft | 10.3 m33.7 ft |
| 10 m33 ft | 20.5 m67.4 ft |
| 15 m49 ft | 30.8 m101 ft |
| 20 m66 ft | 41.1 m135 ft |
| 30 m98 ft | 61.6 m202 ft |
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 set it up
Written for the Uho-S3S-M33D from its official datasheet: two 3 MP channels on one IP, a fixed 91.5° Panorama lens plus a motorized Detail lens (355° pan, -15° to 90° tilt, 4X digital zoom), 10 m IR and warm light, tampering alarm, 2.4 GHz Wi-Fi 6, USB-C 5 V.
Who it is for
- Owners who need one fixed view that never moves — Unlike the single-lens S3E models, the Panorama channel keeps the door or counter in frame even while the Detail lens is turned elsewhere, so the recording never has a gap caused by panning.
- Families checking on children or elderly parents — The Panorama lens watches the whole room while the Detail lens with 4X digital zoom checks a face or the stove; crying and high-decibel detection add sound alerts.
- Small shops that want tamper alerts — This is the only model in this group with a tampering alarm listed, plus a sound and light warning, so covering or knocking the camera does not go unnoticed.
- Renters and DIY users — Two cameras' worth of views from one USB-C power point (DC 5 V / 1.5 A) and one Wi-Fi connection, with no second IP address to manage.
Where and how to install
- Aim the Panorama first — The Panorama lens has no motor, only a 0° to 15° tilt range, so the camera body's position sets what it sees. Put the unit in a corner or on a shelf about 1.8–2.2 m high facing the main door or counter, then use the Detail lens for everything else.
- A full 1.5 A power supply — Maximum consumption is 7.5 W, which is the full output of a 5 V 1.5 A supply, higher than the 5.5–5.6 W of the S3E single-lens models. Use an adapter rated 5 V at least 1.5 A and a good USB-C cable; a weak phone charger causes reboots when the motor and lights run.
- Two streams over Wi-Fi — Both channels share one 2.4 GHz link (802.11b/g/n/ax), so up to about 4 Mbps leaves the camera at the 2048 Kbps maximum per channel. Keep the router within one or two interior walls, or use the RJ45 10/100 port when the Wi-Fi is weak.
- Night light and glass — Warm light is on the Detail channel only (Panorama: N/A). Keep windows and glass doors at the side of both views, since IR and warm light reflect off glass and wash the image white.
- Indoor conditions only — Working range is -10 °C to 50 °C, up to 95% humidity non-condensing, with 4 KV surge protection. No IP rating is listed, so keep it away from rain, steam and kitchen grease.
Panorama + Detail: what each lens of the Uho-S3S-M33D sees
The Panorama channel is the overview: a fixed 91.5° view that covers about 10.3 m of width at 5 m. The Detail channel is the one that moves and zooms; the datasheet gives its DORI figures for a 4.0 mm lens, with faces identifiable up to 7.3 m and a known person recognizable up to 14.7 m. Both channels are 3 MP at up to 15 fps.
| Panorama · fixed | Detail · 4.0 mm · PT | |
|---|---|---|
| Horizontal view angle | 91.5° | — |
| Width covered at 3 m | 6.2 m | — |
| Width covered at 5 m | 10.3 m | — |
| Width covered at 10 m | 20.5 m | — |
| Pixels per meter at 5 m | ≈ 224 px/m | — |
| Identify a stranger's face up to | — | 7.3 m |
| Recognize someone you know up to | — | 14.7 m |
| Observe what is happening up to | — | 29.4 m |
| Detect that something is there up to | — | 73.5 m |
| Zoom | N/A | 4X digital |
| Pan range | N/A | 0° ~ 355° |
| Tilt range | 0° ~ 15° | -15° ~ 90° |
| IR night vision distance | 10 m | 10 m |
| Warm light distance (color at night) | N/A | 10 m |
| Max. frame rate (3 MP) | 15 fps | 15 fps |
- Use the Panorama lens for the spot that must always be recorded, such as the entrance or till, from 3–5 m: it covers 6.2–10.3 m of width.
- Use the Detail lens and its 20 presets for faces and objects: within 7.3 m it reaches identification level.
- Need more detail on both channels? The Uho-S3S-M55D is the 5 MP + 5 MP version of this camera.
Panorama widths are calculated from the 91.5° horizontal view in the official datasheet (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = 2304 ÷ width. The datasheet gives no separate view angle for the Detail lens; its distances are the manufacturer's DORI figures for the 4.0 mm lens.

Dual-Lens Wi-Fi Camera FAQ — Uho-S3S-M33D
Why does the Uho-S3S-M33D have two lenses?
One camera does two jobs on a single IP address: a fixed 3MP Panorama lens watches the whole room all the time, while a motorized 3MP Detail lens pans 355° with 4X digital zoom to follow the action up close. No second camera or cabling point needed.
How far can it detect and recognize a person?
With the 4.0 mm lens the DORI figures are: detect 73.5 m, observe 29.4 m, recognize 14.7 m and identify 7.3 m. Horizontal field of view is 91.5°. For clear faces at a doorway or counter, keep the subject within roughly 7 m.
Does it have color night vision?
Yes, two modes on the Detail lens: 850 nm infrared up to 10 m for discreet black-and-white video, or warm light up to 10 m for full-color night vision. Light control is auto or manual, so you can switch back to IR-only whenever discretion matters more.
What detections does it support besides motion?
Ultra motion detection classifies human, vehicle and pet, cutting false alerts from shadows or curtains. It also supports standard motion detection, crying detection, high-decibel sound detection and a tampering alarm — useful in shops, nurseries and small offices where audio events matter as much as movement.
How much bandwidth and storage does it need?
Main stream is 3MP (2304×1296) at up to 15 fps with a bit rate of 128–2048 Kbps using Ultra 265/H.265/H.264 — light enough for typical home or shop broadband. Recordings go to a MicroSD card up to 512 GB, and ANR backfills network storage after an outage.
Can I talk through the camera?
Yes, two-way audio is built in, with G.711U/G.711A compression, a 64 Kbps bit rate, 8 kHz sampling and noise suppression. You can listen to the room and answer back remotely — practical for a front desk, stockroom, nursery or home use.
Does the Detail lens of the Uho-S3S-M33D follow people automatically?
Auto tracking is not listed in the Uho-S3S-M33D datasheet, unlike the single-lens Uho-S3E models where it is. You move the Detail lens from the app or call one of its 20 presets, while the Panorama lens keeps the whole room recorded so nothing is missed while you steer. If automatic following is essential, ask us to confirm the current firmware before ordering.
The Uho-S3S-M33D records at 15 fps — is that smooth enough?
For home and shop monitoring, yes: 15 fps on each of the two 3 MP channels shows people walking, sitting and handling objects clearly. Very fast hand movements look slightly stepped compared with 25–30 fps, and each frame is still a full 3 MP image for evidence. The single-lens S3E models reach 25 fps at 3 MP if smooth motion matters more than a second view.
What happens if someone covers or knocks the Uho-S3S-M33D?
The datasheet lists a tampering alarm, which raises an event when the view is suddenly blocked or changed, and a sound and light warning to make an alarm noticeable on site. Turn on the tampering alarm in the settings and test it by covering the lens with your hand. Placing the camera at about 2 m or higher also makes it harder to reach in the first place.
Can the Uho-S3S-M33D stop watching while the family is at home?
Only partly. You can park the Detail lens on a preset facing a wall, but the fixed Panorama lens keeps its view, and no privacy button is listed; privacy masking is listed for NVR recording only. The simple, certain way is to unplug the USB-C power. If a one-press privacy mode is important, the Uho-S3E-M3TD-A and Uho-S3E-M5TD-A have an Action touch button for it.
How should I set up night lighting on the Uho-S3S-M33D in a bedroom or shop?
In bedrooms, set the light to IR (Auto/Manual control is available): 850 nm IR reaches 10 m and does not light up the room, so sleep is not disturbed. In a closed shop, the 10 m warm light on the Detail channel gives a color image of clothing and faces and shows that the camera is active. Keep glass out of the centre of both views at night, or the reflection turns the picture white.
Do I need a cloud subscription to record?
No. Recording to the on-board microSD card works without any subscription. If you want to record to your own NVR or server, check the protocols listed in the specification table (RTSP / ONVIF) or send us the name of your recording software and we will confirm compatibility before you order.
Does the Uho-S3S-M33D support Wi-Fi 6 and 5 GHz networks?
It supports Wi-Fi 6 (IEEE 802.11ax) as well as 802.11b/g/n, but only in the 2.4 GHz band (2.4–2.4835 GHz); 5 GHz is not supported. With 20/40 MHz channels it reaches up to 270 Mbps on 802.11ax and 150 Mbps on 802.11n, and it uses WPA-PSK/WPA2-PSK security. Make sure your router's 2.4 GHz band is enabled.
Is the Uho-S3S-M33D suitable for a small shop or reception area?
Yes, indoors. The fixed Panorama lens keeps a 91.5° overview of the room at all times while the Detail lens pans 355°, tilts -15° to 90° and zooms 4X digitally, so the camera never loses the overall view while it looks at something specific. It also offers a tampering alarm and 20 presets, and is rated for indoor conditions of -10 °C to 50 °C.
Uho-S3S-M33D or Uho-S3S-M55D: what is the difference?
Both are Uniarch dual-lens indoor Wi-Fi pan-tilt cameras with a Panorama and a Detail lens on one IP address; the difference is resolution. The Uho-S3S-M33D records 3MP + 3MP (2304×1296 per lens, max. 15 fps), while the Uho-S3S-M55D is a 5MP + 5MP model. Choose the M55D when you need more detail from each lens, and the M33D when 3MP per lens is sufficient.
What power and cabling does the Uho-S3S-M33D need?
It runs on DC 5 V/1.5 A through a USB Type-C input, and its maximum consumption is 7.5 W, the full rating of that supply (5 V × 1.5 A), so use an adapter rated at least 1.5 A. Both lenses share this single power supply and one network link, either 2.4 GHz Wi-Fi or the 1 × RJ45 10/100 M Ethernet port. The spec lists no PoE, so a cabled installation still needs the USB-C power adapter.
