The Uniarch Uho-S3S-M55D puts two independent 5MP lenses on one indoor Wi-Fi camera body, sharing a single IP address and a single USB-C power connection. The fixed Panorama lens (79.0° 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 | 79.0° |
|---|---|
| 5 m16 ft | 8.2 m27.0 ft |
| 10 m33 ft | 16.5 m54.1 ft |
| 15 m49 ft | 24.7 m81.1 ft |
| 20 m66 ft | 33.0 m108 ft |
| 30 m98 ft | 49.5 m162 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-M55D from its official datasheet: two 5MP channels on one IP (fixed Panorama + pan-tilt Detail, 4.0 mm, 79.0°), 2.4 GHz Wi-Fi or RJ45, IR and warm light to 10 m, USB-C 5V power.
Who it is for
- Parents and carers — Keep one 5MP channel fixed on the cot or bed and use the other to look around the room; crying detection and loud sound detection push an alert to the phone.
- Small offices and reception areas — Panorama watches the entrance all the time while the Detail lens patrols up to 20 presets such as the cabinet, the safe or a second door.
- Pet owners — Pet is a separate class in Ultra motion detection, and the Detail lens's warm light keeps night video in color within 10 m.
- Apartments and rented homes — Nothing to drill or wire: it sits on a shelf, runs on USB-C DC 5V/1.5A, connects over 2.4 GHz Wi-Fi and records locally to microSD up to 512 GB.
Where and how to install
- Height and ceiling mounting — A shelf or wall at about 2–2.5 m gives faces from the front. On a ceiling it hangs upside down; set Flip to 180° in the image settings so the picture is the right way up.
- Aim the fixed lens first — The Panorama lens does not pan, so turn the whole camera until it faces the most important area; at 3 m its 79.0° view covers about 4.9 m of width. The Detail lens can then pan 355° to the rest of the room.
- Wi-Fi signal or cable — The antenna is internal and works on 2.4 GHz only. Keep it out of metal cabinets and away from microwave ovens and the back of a TV; if the signal is poor, plug a cable into the RJ45 10/100 Mbps port.
- Power supply — Use the supplied USB Type-C adapter or another rated DC 5V/1.5A or more. Undersized phone chargers and long thin USB extension cables are a common cause of reboots when the motor and lights switch on.
- Indoor climate and light — Rated -10 °C to 50 °C and ≤ 95% RH non-condensing, with no waterproof rating: keep it out of bathrooms, porches and steam. BLC is supported, but still avoid a bright window straight behind the scene, and do not film through glass at night because the IR reflects back.
Panorama and Detail: what each channel sees
The official datasheet publishes one shared lens row for both channels: 4.0 mm, 79.0° horizontal, 5MP (2880 × 1620). So the two channels see the same width at the same distance; the difference is that Panorama stays where you aimed the camera, while Detail pans 355°, tilts -15° to 90° and adds 4X digital zoom. For a wider fixed overview, the sibling Uho-S3S-M55F36D has a 2.8 mm Panorama lens.
| Panorama · 4.0 mm (fixed) | Detail · 4.0 mm (pan-tilt) | |
|---|---|---|
| Horizontal view angle | 79.0° | 79.0° |
| Width covered at 3 m | 4.9 m | 4.9 m |
| Width covered at 5 m | 8.2 m | 8.2 m |
| Width covered at 10 m | 16.5 m | 16.5 m |
| Pixels per meter at 5 m | 349 | 349 |
| Identify a stranger's face up to | 9.0 m | 9.0 m |
| Recognize someone you know up to | 18.0 m | 18.0 m |
| Detect that something is there up to | 90.0 m | 90.0 m |
| Movement | tilt 0°–15°, no pan | pan 0°–355°, tilt -15°–90°, 4X digital zoom |
- Point the Panorama channel at the door or the cot: up to 9.0 m away a face is still identifiable, and that view never moves away.
- Use the Detail channel for everything else in the room, saved as presets; at 5 m each view is about 8.2 m wide.
Widths are calculated from the horizontal view angle in the official datasheet (width = 2 × distance × tan(angle ÷ 2)); pixels per meter = horizontal pixels ÷ width. As a common rule of thumb, about 250 pixels per meter is enough to identify a face and about 125 to recognize a known person.

5MP Dual-Lens Wi-Fi Camera FAQ — Uho-S3S-M55D
What do the two 5MP lenses on the Uho-S3S-M55D do?
The fixed 5MP Panorama lens keeps the whole room in view permanently, while the motorized 5MP Detail lens pans 355° with 4X digital zoom to follow subjects closely. Both run on a single IP address, so you install and manage one camera instead of two.
How far can it see?
With the 4.0 mm lens the DORI distances are: detect 90 m, observe 36 m, recognize 18 m and identify 9 m. Horizontal field of view is 79°, so it suits rooms and halls where you need reach more than width.
How does it perform in low light?
Minimum illumination is 0.01 lux in colour (F2.0, AGC on) and 0 lux with IR active. The Detail lens carries 850 nm infrared up to 10 m for discreet black-and-white night vision, or warm light up to 10 m for full-color video after dark.
What recording resolution and frame rate does it deliver?
Main stream runs 5MP (2880×1620) at up to 15 fps, with 4MP, 3MP and 2MP options also at 15 fps. Compression is Ultra 265/H.265/H.264 at 128–2048 Kbps with dual streams, so a 5MP feed stays light on bandwidth.
Does it store video without an NVR?
Yes. A MicroSD card up to 512 GB records at the edge, and ANR support means footage cached on the card backfills network storage after a connection drop. Privacy mask is available when the camera is paired with an NVR.
What detection and audio features are included?
Detection: motion, Ultra motion detection (human/vehicle/pet), loud sound detection, crying detection and tampering alarm. Audio: built-in two-way audio with G.711U/G.711A at 64 Kbps, 8 kHz sampling and noise suppression, so you can listen and answer back through the camera.
My Uho-S3S-M55D will not join the Wi-Fi or keeps dropping. What router settings matter?
It works only on 2.4 GHz (2.4 GHz to 2.4835 GHz) with WPA-PSK/WPA2-PSK security, so the router must offer a 2.4 GHz network and must not be set to WPA3-only. If the router merges 2.4 and 5 GHz under one name, temporarily give the 2.4 GHz band its own name during setup. Drop-outs are usually signal strength: move it closer to the router, add a 2.4 GHz access point, or use the RJ45 port; both channels at the 2048 Kbps maximum need about 4.1 Mbps of upload.
In the app, how do I use the two channels of the Uho-S3S-M55D together?
It is added as one device with one IP address and shows two channels, Panorama and Detail, side by side in a split screen. Leave Panorama as the fixed overview and steer the Detail channel with the pan-tilt controls or its 20 presets; you can also open Detail full screen to use the 4X digital zoom. Both channels can record to the same microSD card.
Can family members or staff watch the Uho-S3S-M55D without my admin password?
Yes. Add the camera to your own account in the Uniarch app, then use the app's device-sharing function to share it with the other person's app account, so the admin password never leaves your hands. For a PC at a reception desk, the Uniarch client can be used. If you later remove the share, that person loses access without you changing any camera settings.
Is there a privacy setting on the Uho-S3S-M55D for when people are at home or at work?
The official datasheet does not list a privacy mode, and its privacy mask is supported only when the camera records to an NVR. The current Uniarch app lists a privacy-mode setting for dual-lens cameras, but availability depends on app and firmware version, so ask us to confirm before you order if you need it. What always works: an alarm and recording schedule limited to the hours when nobody should be there, or simply unplugging the USB-C power.
Does the Uho-S3S-M55D keep recording during a power cut?
No. It has no internal battery and no PoE input, so recording stops when the USB-C adapter loses power; footage already on the microSD card is kept. When power is back it boots and rejoins the saved Wi-Fi as soon as the router is up. A small UPS feeding both the camera adapter and the router covers short cuts; the camera itself needs at most 5V × 1.5A = 7.5 W.
The Uho-S3S-M55D alerts me for every movement. How do I tune human alerts?
Switch from plain motion detection to Ultra motion detection and enable only the human class (add pet only if you want pet alerts). Draw the detection area so it leaves out TVs, fans, curtains and mirrors, and lower the sensitivity if moving shadows still trigger it. Turn off loud sound detection where there is music or traffic noise, and use a schedule so alerts arrive only when the room should be empty.
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.
Is the Uho-S3S-M55D suitable for a small shop floor or office?
Yes, for indoor spaces within its -10 °C to 50 °C working range. The fixed 5MP Panorama lens keeps a 79.0° overview of the room while the 5MP Detail lens pans 355°, tilts -15° to 90° and zooms 4X digitally onto a counter, shelf or door. You can store up to 20 presets, and it alerts on human, vehicle and pet motion, loud sound, crying and tampering.
How many days do both lenses of the Uho-S3S-M55D record on a 512 GB microSD card?
About 11.6 days, assuming both channels record continuously at the maximum 2048 Kbps each (4096 Kbps total). Calculation: 512 GB × 8 = 4,096 Gbit ÷ 4.096 Mbps = 1,000,000 s ≈ 11.6 days (decimal GB, no overhead). On the same basis a 256 GB card holds about 5.8 days and 128 GB about 2.9 days; lower bitrates or motion-only recording extend this.
What is the difference between the Uho-S3S-M55D and the Uho-S3S-M55F36D?
Both are 5MP+5MP dual-lens indoor Wi-Fi cameras; the difference is the lens. The Uho-S3S-M55D has its DORI figures rated with a 4.0 mm lens and a 79.0° Panorama view, which suits covering a whole room. The Uho-S3S-M55F36D uses a 6 mm lens per its title, which gives a narrower view that reaches farther, so pick it for long rooms, corridors or a distant entrance.
How do I power and connect the Uho-S3S-M55D?
It runs on DC 5 V/1.5 A through a USB Type-C port, so use a 5 V adapter rated at least 1.5 A. It joins 2.4 GHz Wi-Fi only, supporting 802.11b/g/n/ax (Wi-Fi 6) with WEP or WPA-PSK/WPA2-PSK, and also has a 10/100 Mbps RJ45 port. Both lenses share one IP address and are viewed in the Uniarch client or APP, with RTSP and API listed for integration.
