2-in-1Panorama + Detail, one IP
355°Detail lens pan range
10 mIR + warm-light distance
Wi-Fi2.4GHz, no cable needed

The Uniarch Uho-S3S-M33F36D 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 2.8mm Panorama lens (109.2° view) keeps the whole room in frame at all times, while the motorized 6.0mm Detail lens (355° pan, -15°~90° tilt, 4X digital zoom) reaches over twice as far 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.

Unlike the plain M33D, this F36D variant's datasheet publishes separate DORI figures for both lenses — the 2.8mm Panorama and the 6.0mm Detail — because they are genuinely different focal lengths, not just a fixed lens plus its own digital zoom.

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 set it up

Written for the Uho-S3S-M33F36D from its official datasheet: two 3MP lenses on one IP (2.8 mm fixed Panorama + 6.0 mm pan-tilt Detail), 2.4 GHz Wi-Fi or RJ45, IR and warm light to 10 m, USB-C 5V power.

Who it is for

  • Families with a baby or an elderly relative — Panorama keeps the whole room in view while Detail zooms toward the cot or armchair; crying detection and loud sound detection send an alert, and two-way audio lets you speak to the room.
  • Small shops, pharmacies and reception desks — One camera covers the counter and the door (109.2° Panorama) and the Detail lens can be sent to up to 20 saved presets, for example the cash register or a high-value shelf.
  • Pet owners — Ultra motion detection classifies pets separately from people, and the warm light on the Detail lens gives color video after dark within 10 m.
  • Renters and DIY buyers — No drilling or network cable is required: it stands on a shelf, runs from a USB-C DC 5V/1.5A supply, joins 2.4 GHz Wi-Fi and records to a microSD card up to 512 GB.

Where and how to install

  • Shelf, wall or ceiling — Place it about 2–2.5 m high on a shelf or wall so faces are seen from the front, not from above. Mounted upside down on a ceiling, set the image Flip to 180° in the settings so the picture is upright.
  • Use a corner — From a room corner the 109.2° Panorama lens covers almost the whole room (about 8.4 m of width at 3 m), and the Detail lens can still pan 355° to anything it spots.
  • Good 2.4 GHz signal or a cable — The antenna is built in, so keep the camera out of metal cabinets and away from the back of a TV or microwave oven, ideally no more than one or two walls from the router. Where Wi-Fi is weak, use the RJ45 10/100 Mbps port instead.
  • Power from the right adapter — It needs DC 5V/1.5A on USB Type-C. Use the supplied adapter or one rated at least 5V/1.5A; a weak phone charger or a long thin USB cable can cause reboots when the motor and lights run.
  • Indoors only, away from windows and glare — Working range is -10 °C to 50 °C and ≤ 95% RH non-condensing, with no weatherproof rating, so avoid bathrooms, steamy kitchens and porches. Do not aim it through a window: IR reflects off the glass at night, and with only digital WDR (no BLC/HLC) a bright window behind a person darkens the face.

Panorama 2.8 mm vs Detail 6.0 mm: what each lens sees

Both lenses are 3MP (2304 × 1296), so the difference is reach versus width. Panorama covers about 2.7× more width; Detail puts about 2.7× more pixels on every meter and identifies a face at 11.0 m instead of 5.1 m. In practice Panorama tells you something happened, Detail shows who it was.

Detect that something is there up to51.4 m110.2 m
Movementtilt 0°–15°, no panpan 0°–355°, tilt -15°–90°
  • Count on Panorama for the whole room: at 5 m it covers 14.1 m of width, enough for a living room or a shop floor from one corner.
  • Save a Detail preset on the door or counter if it is 5–11 m away: there Panorama only sees a person, Detail can still identify the face.
  • The 4X zoom on Detail is digital: it enlarges the image but does not add detail beyond the 11.0 m identify distance.

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.

Dual-Lens Wi-Fi Camera FAQ — Uho-S3S-M33F36D

What is the lens setup on the Uho-S3S-M33F36D?
A fixed 2.8 mm 3MP Panorama lens gives a 109.2° wide view of the whole room, while a motorized 6.0 mm 3MP Detail lens pans 355° with 4X digital zoom to get closer to what matters. Both share one IP address and one mounting point.
Which Wi-Fi network does it connect to?
It uses 2.4 GHz Wi-Fi (IEEE 802.11b/g/n/ax) with a built-in antenna. 2.4 GHz carries further through walls than 5 GHz, which suits homes and shops where the router sits in another room. Make sure your router broadcasts a 2.4 GHz SSID before installing.
How far can it see with the wide lens?
DORI figures for the 2.8 mm panorama lens: detect 51.4 m, observe 20.6 m, recognize 10.3 m, identify 5.1 m. That covers a living room, small shop or office comfortably; for a tighter look at distance, the 6.0 mm Detail lens takes over.
Does night vision show color?
You choose per scene: 850 nm IR on the Detail lens lights up to 10 m in discreet black-and-white, or warm light up to 10 m keeps the picture in full color after dark. Control is auto or manual, so switch to IR-only when nothing should be visible.
What alerts can it send?
Detection covers motion, Ultra motion detection with human/vehicle/pet classification, loud sound detection, crying detection and a tampering alarm. Classification filters alerts so a passing pet or a moving curtain does not trigger the same response as a person entering the room.
How does it record and how much data does it use?
Main stream is 3MP (2304×1296) at up to 15 fps, bit rate 128–2048 Kbps with Ultra 265/H.265/H.264 compression — manageable on a modest connection. Storage is a MicroSD card up to 512 GB in the camera, plus ANR to backfill network storage after a dropout.
Where should I put the router or the Uho-S3S-M33F36D for a stable Wi-Fi connection?
Keep it in clear range of a 2.4 GHz access point, ideally within one or two walls, and not inside metal furniture: the antenna is built in. The camera supports WPA-PSK/WPA2-PSK, so a router set to WPA3-only will not accept it; use WPA2 or WPA2/WPA3 mixed mode. If both lenses stream at the 2048 Kbps maximum, that is about 4.1 Mbps of upload from one camera, so in a weak spot use the RJ45 port or add a 2.4 GHz access point near the camera.
How do the two lenses of the Uho-S3S-M33F36D appear in the app?
The camera is one device with one IP address but two video channels, Panorama and Detail. You can view them side by side in a split screen or open Detail alone to pan, tilt and zoom on what Panorama spotted. Saving up to 20 presets, for example door, counter and cot, lets you send the Detail lens there with one tap.
Does the Uho-S3S-M33F36D have a privacy mode so it is not watching when we are at home?
A privacy mode is not listed in the official datasheet, and its privacy mask works only together with an NVR. The current Uniarch mobile app shows a privacy-mode setting for dual-lens cameras, but whether it appears depends on app and firmware version, so tell us if this is a must and we will confirm before you order. The certain options are an alarm schedule that only alerts when you are away, or unplugging the USB-C power.
What happens to the Uho-S3S-M33F36D during a power cut?
It has no battery and no PoE, so it stops recording when the USB-C supply loses power; video already on the microSD card stays there. When power returns it restarts and reconnects to the saved Wi-Fi network once the router is back. To bridge short outages, put the camera adapter and the router on a small UPS: the camera needs at most 5V × 1.5A = 7.5 W.
How do I stop the Uho-S3S-M33F36D from sending too many alerts?
Use Ultra motion detection instead of plain motion detection and tick only the targets you care about: human, and pet only if you want pet alerts. Keep a TV, a fan, curtains near an open window or a mirror out of the detection area, and switch off loud sound detection in a noisy shop. Set an alarm schedule so alerts arrive only outside opening hours or when the family is away.
How well does two-way audio work on the Uho-S3S-M33F36D?
It has a built-in mic and speaker with audio suppression, so you can talk to the room from the app, for example to calm a pet or greet a customer. Audio is G.711 at 8 kHz, which is phone-call quality: clear for speech, not meant for music. For best results keep the camera within a few meters of where people stand and away from loud machines or speakers.
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-M33F36D suitable for a long shop aisle or an indoor warehouse aisle?
Yes, indoors: the 6.0 mm Detail lens identifies a person at up to 11.0 m and recognizes at 22.0 m, while the 2.8 mm Panorama lens keeps a 109.2° overview of the area around the camera. The Detail lens pans 355° and tilts -15° to 90°, so it can be aimed down the aisle. Its IR and warm light reach 10 m, so night detail further down a long aisle depends on existing lighting, and it is an indoor model rated -10 °C to 50 °C.
How many days of video from both lenses fit on a microSD card in the Uho-S3S-M33F36D?
Assuming both channels record continuously at the 2048 Kbps maximum stated bit rate (4096 Kbps combined), the Uho-S3S-M33F36D writes about 44.2 GB per day, so a 128 GB card holds about 2.9 days, 256 GB about 5.8 days and the maximum 512 GB card about 11.6 days. Lowering the bit rate (down to 128 Kbps) or recording on motion events only extends this.
What is the difference between the Uho-S3S-M33F36D and the outdoor Uho-P2S-M33F34?
Both are 3MP+3MP dual-lens Wi-Fi cameras on one IP address. The Uho-S3S-M33F36D is the indoor model with a longer 6.0 mm Detail lens (identify 11.0 m) and 5 V USB-C power, while the Uho-P2S-M33F34 is the IP66 outdoor model with a 4.0 mm Detail lens (identify 7.3 m), IR and warm light to 30 m and DC 12 V power. Pick the Uho-S3S-M33F36D for shops, offices and aisles, and the Uho-P2S-M33F34 for yards, gates and building exteriors.
Can I connect the Uho-S3S-M33F36D by cable and view both lenses on a PC?
Yes. The Uho-S3S-M33F36D has one 10/100 Mbps RJ45 port in addition to 2.4 GHz Wi-Fi, and both lenses appear as two channels under a single IP address in the APP, the Uniarch client or a web browser with plug-in live view. Power is DC 5 V/1.5 A through USB Type-C, and RTSP with authentication and an API are supported for integration.
