The Uniarch Uho-S3E-M3F3-A is a 3MP indoor Wi-Fi camera on a motorized pan-tilt base, panning 355° and tilting from -15° to 90° across 20 saved presets. It follows moving subjects with auto tracking, talks back through a built-in mic and speaker, and sees up to 10m in the dark with IR night vision. It runs off any USB-C 5V/1.5A power source and connects over 2.4GHz Wi-Fi, with MicroSD storage up to 512GB for local recording.
Is this the right camera for you?
Plain-language guide for buyers and installers — based only on what this camera actually does.
One camera, whole-room coverage355° motorized pan and a wide tilt range mean one ceiling or shelf-mounted unit can cover most of a living room, office or shop floor — no blind corner left to a fixed lens.
Nursery & elderly check-insAuto tracking follows a moving baby or family member around the room, and the built-in mic + speaker let you talk to them directly from the app — no separate baby monitor needed.
Pet check-ins while you're outPet detection is a separate category from human/vehicle detection, so alerts on cat or dog movement don't get lost among general motion notifications.
Apartments & rentals without cablingNo PoE switch or NVR cable run needed — plug the included USB-C cable into any 5V outlet and join the Wi-Fi. Take it with you when you move out.
Checking in from your phonePair it with the Uniarch APP for live view, push alerts, remote pan/tilt control and playback from anywhere.
Local backup you controlMicroSD edge storage up to 512GB keeps footage on the camera itself — no monthly cloud subscription required to have a recording.
Not the right pick if you need…
- Outdoor / weatherproof use — this is an indoor-only body, no IP dust/water rating at all
- PoE power — this camera has no PoE port, it needs a USB-C 5V/1.5A power source nearby
- Color night vision — this model has an IR-only illuminator, night video is black & white
- A fixed non-moving mount — the whole point of this model is the motorized pan-tilt base; if you just need a static wide-angle view, a fixed-lens camera may be simpler

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 | 87.8° |
|---|---|
| 5 m16 ft | 9.6 m31.6 ft |
| 10 m33 ft | 19.2 m63.1 ft |
| 15 m49 ft | 28.9 m94.7 ft |
| 20 m66 ft | 38.5 m126 ft |
| 30 m98 ft | 57.7 m189 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-S3E-M3F3-A from its official datasheet: 3 MP, fixed 2.8 mm lens (87.8°), 355° pan and -15° to 90° tilt, 10 m IR, crying detection, 2.4 GHz Wi-Fi or 10/100 Ethernet, USB-C 5 V power.
Who it is for
- Parents watching a cot or play area — The 2.8 mm lens is the widest S3E 3 MP version: from 1.5 m it covers about 2.9 m of width, so the whole cot fits in one view, and crying detection sends an alert when the baby wakes.
- Families caring for an elderly relative — In a bedroom of 3 m or less the wide view sees bed and doorway together, and two-way audio lets relatives check in by voice from the app.
- Small rooms, kiosks and reception desks — When the camera sits 2–3 m from the area, the 87.8° view covers the counter and the person in front of it without having to pan.
- Pet owners in apartments — Ultra motion detection has a pet class, and the wide lens keeps a sofa, food bowl and door in the same frame when the camera is parked on a preset.
Where and how to install
- Over a cot: 1.5–2 m away — Place it on a shelf or wall bracket 1.5–2 m from the cot, slightly above it and looking down. At 1.5 m the view is about 2.9 m wide and 1.4 m high, which frames a standard cot with margin.
- Cable safety — Power is DC 5 V / 1.5 A over USB-C, maximum 5.6 W. Never put the camera or its cable inside or on the edge of the cot; keep the cable at least 1 m away and fixed to the wall.
- Close-range IR — At 1–2 m the 10 m IR is strong; Smart IR evens it out so faces are not washed white. Keep white bedsheets and mirrors out of the centre of the frame, and do not aim through window glass at night.
- Wi-Fi in a back bedroom — Nurseries and bedrooms are often far from the router. It uses 2.4 GHz only, so check the signal in the exact spot before fixing a bracket; if it is weak, add a 2.4 GHz repeater or use the RJ45 10/100 port.
- Indoor conditions only — Working range is -10 °C to 50 °C and up to 95% humidity, non-condensing. Keep it away from humidifiers that blow mist at the lens, bathrooms and the kitchen stove.
Uho-S3E-M3F3-A, 2.8 mm: what you actually see
This model has one fixed 2.8 mm lens with an 87.8° horizontal view, about 1.4× the width of the 4.0 mm Uho-S3E-M3-A (67.3°). The price of that width is detail: about 239 pixels per meter at 5 m, so it is at its best in rooms where people are within about 4–5 m.
| Uho-S3E-M3F3-A · 2.8 mm | |
|---|---|
| Horizontal view angle | 87.8° |
| Vertical view angle | 48.9° |
| Width covered at 1.5 m (over a cot) | 2.9 m |
| Width covered at 3 m | 5.8 m |
| Width covered at 5 m | 9.6 m |
| Width covered at 10 m | 19.2 m |
| Pixels per meter at 5 m | ≈ 239 px/m |
| Pixels per meter at 10 m | ≈ 120 px/m |
| IR night vision distance | 10 m |
| Pan range | 0° ~ 355° |
| Tilt range | -15° ~ 90° |
| Preset positions | 20 |
- Pick the Uho-S3E-M3F3-A (2.8 mm) for nurseries, bedrooms and small shops where the subject is 1.5–4 m away: at 3 m it already covers 5.8 m of width.
- Pick the 4.0 mm Uho-S3E-M3-A when faces must be clear across a larger room 5–6 m deep.
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.

3MP Wide-Angle Indoor Wi-Fi Camera FAQ — Uho-S3E-M3F3-A
How wide is the view of the Uho-S3E-M3F3-A?
Its 2.8 mm F2.0 lens gives 87.8° horizontal, 48.9° vertical and 99.0° diagonal coverage — a genuinely wide view for one wall-mounted unit. Add the motorized 355° pan and auto tracking and a single camera sweeps almost the entire room without blind corners.
When should I pick the 2.8 mm lens version?
Choose the 2.8 mm F3 variant when the camera sits close to the action — small shops, kiosks, living rooms, reception desks — and you want the widest possible scene in frame. The 87.8° horizontal view captures more of the room at short distances than narrower lenses.
What detection and alerts are built in?
Motion detection plus ultra motion detection that classifies human, vehicle and pet targets, along with crying detection and high-decibel detection on the audio side. Auto tracking then follows the subject across the 355° pan range so events stay in frame.
How is video quality and bandwidth managed?
Main stream is 3MP (2304×1296) at up to 25 fps, with 2MP and 720P at 30 fps; the bit rate window is 128–2048 Kbps using Ultra 265, H.265 or H.264 with U-code. Dual streams let a light sub stream handle remote viewing over mobile data.
Does it work at night, and where does it record?
850 nm Smart IR reaches 10 m (32.8 ft) — fine for room distances — with color video down to 0.02 lux and 0 lux in IR mode. Recording goes to a MicroSD card up to 512 GB over 2.4G Wi-Fi (802.11 b/g/n), and ANR back-fills network storage after outages.
Can I get the Uho-S3E-M3F3-A with a 4.0 mm lens instead?
No. The official datasheet lists the Uho-S3E-M3F3-A with one fixed 2.8 mm F2.0 lens (87.8°); "F3" in the model name stands for that lens. The 4.0 mm version is a different model, the Uho-S3E-M3-A (67.3°), with otherwise the same 3 MP sensor, 355° pan, 10 m IR and Wi-Fi.
Can the Uho-S3E-M3F3-A detect a fall or replace a medical alarm for an elderly person?
No. Fall detection is not listed; the alerts are motion, Ultra motion (human/vehicle/pet), crying and high-decibel detection. It is useful for checking in: high-decibel detection can flag a shout or a loud noise, and two-way audio lets you talk to the person. For emergencies, keep a dedicated alarm or call button as well.
Is the two-way audio on the Uho-S3E-M3F3-A clear enough for a conversation?
It is voice-grade audio: G.711 at 8 kHz and 64 Kbps, with audio suppression supported, which is fine for short exchanges like "I'm on my way" or calming a child. Expect a short delay over the internet, so speak in turns rather than over each other. Clarity is best within a few meters of the camera and away from a TV or fan.
Why does the Uho-S3E-M3F3-A send alerts when nobody is in the room, and how do I reduce them?
Plain motion detection reacts to any change in the picture: curtains in a breeze, a ceiling fan, the TV screen, car headlights on the wall or the IR switching at dusk. Switch to Ultra motion detection and select only the human (or pet) class, keep the TV and windows out of the detection area, and lower the sensitivity. The wide 87.8° view sees more of these sources than the 4.0 mm sibling, so masking the area matters more.
Can I mount the Uho-S3E-M3F3-A upside down on the ceiling above a play area?
Yes, the image can be flipped 180° in settings so the picture is the right way up. A ceiling position keeps the camera and cable out of children's reach and, with the 87.8° lens, a 2.5 m ceiling gives a wide view of the floor below. Check the mounting method of your unit with us before ordering, as no mounting accessory is listed on the datasheet.
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-S3E-M3F3-A suitable for a small shop or office?
Yes, indoors: the motorized head pans 355° and tilts -15° to 90°, so with 20 presets and auto tracking one Uho-S3E-M3F3-A can cover a whole small room from a single mounting point. IR night vision reaches 10 m for after-hours monitoring. It is not meant for outdoor mounting, as no IP rating is listed and it is rated for -10 °C to 50 °C.
How many days of video does a microSD card hold in the Uho-S3E-M3F3-A?
At the maximum stated bit rate of 2048 Kbps with continuous 24-hour recording, the Uho-S3E-M3F3-A writes about 22.1 GB per day, so a 128 GB card holds about 5.8 days, 256 GB about 11.6 days and the maximum supported 512 GB card about 23 days. Setting a lower bit rate (the range starts at 128 Kbps) or recording on motion events only makes the card last longer.
Should I choose the Uho-S3E-M3F3-A or the Uho-S3E-M3TD-A?
Both are 3MP indoor Wi-Fi cameras; the practical difference is night lighting. The Uho-S3E-M3F3-A uses IR only as its supplemental light, giving black-and-white night video up to 10 m, while the Uho-S3E-M3TD-A is the dual-light version. Pick the Uho-S3E-M3TD-A if you want the option of color video at night, and the Uho-S3E-M3F3-A if standard IR night view is enough.
How is the Uho-S3E-M3F3-A powered and connected, and what software works with it?
The Uho-S3E-M3F3-A runs on DC 5 V/1.5 A through a USB Type-C port (max 5.6 W), so a standard USB-C phone charger of that rating works. It connects over 2.4 GHz Wi-Fi (802.11b/g/n) or its 10/100 Mbps RJ45 port, and is viewed in the mobile APP, the Uniarch client or a web browser with plug-in live view. RTSP with authentication, an API and an SDK are listed for integration.
