The Uniarch Uho-S3E-M3TD-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, switches between IR and warm-light illumination when a preset is triggered, and has a physical Action Touch button on top for one-tap calling or privacy mode. It runs off any USB-C 5V/1.5A power source and connects over 2.4GHz Wi-Fi 6 (802.11ax), 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.
One-tap privacy when you're homeThe Action Touch button on top of the unit lets anyone in the room switch the camera into privacy mode or place a call without opening the app first.
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
- Full-time color night vision — the warm light only turns on when a preset is triggered, for scene illumination; by default night video is IR-lit 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

Night vision: switchable IR / warm light
Dual Light mode switches between IR and warm light automatically when a preset is triggered.
IR MODE
Invisible infrared — discreet black & white night vision
IR night vision up to 10 m (32.8 ft.) at 850 nm — the default at night, discreet and unlit.
WARM LIGHT MODE
Visible warm light — turns on when a preset is triggered
Warm-light illumination up to 10 m (32.8 ft.), switched on together with the Dual Light mode when a saved preset position is triggered — useful for scenes where a lit, visible response is preferred over silent IR.
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 | 67.3° |
|---|---|
| 5 m16 ft | 6.7 m21.8 ft |
| 10 m33 ft | 13.3 m43.7 ft |
| 15 m49 ft | 20.0 m65.5 ft |
| 20 m66 ft | 26.6 m87.4 ft |
| 30 m98 ft | 39.9 m131 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-M3TD-A from its official datasheet: 3 MP, fixed 4.0 mm lens (67.3°), 355° pan with auto tracking, dual light (10 m IR + 10 m warm light), Action touch button, 2.4 GHz Wi-Fi 6, USB-C 5 V power.
Who it is for
- Elderly relatives living alone — The Action touch button on top supports calling, so the person at home presses one physical button instead of opening an app, and two-way audio carries the conversation.
- Households that want privacy on demand — The same button supports privacy mode, so anyone in the room can switch the camera off-duty without a phone; this is the main difference from the Uho-S3E-M3-A.
- Shops and offices after closing time — Auto tracking follows a person across the floor, and Dual Light mode can switch from IR to the 10 m warm light for a color picture and a visible sign that the room is watched.
- Parents and pet owners — Crying detection, high-decibel detection and the pet class in Ultra motion detection cover the usual home alerts, with 20 presets for the cot, sofa and door.
Where and how to install
- Button within reach, lens out of reach — Because the Action touch button is on top of the camera, put it where the user can press it, such as a sideboard or bedside shelf about 1.2–1.5 m high, rather than on a high shelf. If it is mounted upside down on a ceiling, the button cannot be used.
- Warm light and bedrooms — The warm light is visible to people in the room. In a bedroom or nursery keep night viewing on IR (850 nm, not visible as a lamp) and save the warm-light behaviour for presets that look at living areas or a shop floor.
- Away from windows and glass doors — Both IR and warm light bounce off glass and wash out the image. A shop camera looking at a glass front at night should be placed beside the glass, not facing it, or that preset should use no light.
- Wi-Fi 6 on 2.4 GHz — The radio is 2.4 GHz only (802.11b/g/n/ax, 20/40 MHz). Keep the router within one or two interior walls; in a busy shop strip of many routers, 20 MHz on channel 1, 6 or 11 is usually more stable than 40 MHz. The RJ45 10/100 port is there for a fixed wired install.
- Power and environment — DC 5 V / 1.5 A over USB-C, maximum 5.5 W; use an adapter rated at least 1.5 A. Indoor only: -10 °C to 50 °C and up to 95% humidity, non-condensing.
Uho-S3E-M3TD-A, 4.0 mm: what you actually see
Same 3 MP sensor and 4.0 mm lens (67.3°) as the Uho-S3E-M3-A, so the view is identical: about 6.7 m wide at 5 m with about 346 pixels per meter. What the TD adds is the 10 m warm light next to the 10 m IR, and the Action touch button.
| Uho-S3E-M3TD-A · 4.0 mm | |
|---|---|
| Horizontal view angle | 67.3° |
| Vertical view angle | 37.2° |
| Width covered at 3 m | 4.0 m |
| Width covered at 5 m | 6.7 m |
| Width covered at 10 m | 13.3 m |
| Pixels per meter at 5 m | ≈ 346 px/m |
| Pixels per meter at 10 m | ≈ 173 px/m |
| IR night vision distance | 10 m |
| Warm light distance (color at night) | 10 m |
| Pan range | 0° ~ 355° |
| Tilt range | -15° ~ 90° |
| Preset positions | 20 |
| Action touch button (call / privacy) | ✓ |
- Pick the Uho-S3E-M3TD-A over the Uho-S3E-M3-A when someone at home needs the one-press call or privacy button, or when you want color video from the warm light within 10 m at night.
- Pick the 5 MP Uho-S3E-M5TD-A when the room is wider: its 84.0° view covers more width with more pixels.
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 Dual Light Indoor Wi-Fi Camera FAQ — Uho-S3E-M3TD-A
What does dual light mean on the Uho-S3E-M3TD-A?
It carries two illuminators, each reaching 10 m (32.8 ft): invisible 850 nm infrared as the discreet default at night, plus a visible warm light that switches on with Dual Light mode when a saved preset position is triggered — giving full-color footage on demand.
How much of the room does the pan-tilt cover?
The motorized mount pans 355° — nearly a full turn — and the 4.0 mm F2.0 lens gives a 67.3° horizontal, 77.8° diagonal view. With auto tracking on, the camera rotates to follow a person, so one corner-mounted unit covers a living room, stockroom or small shop.
What alerts can it send for a home or small shop?
Ultra motion detection classifies human, vehicle and pet targets, and the microphone side adds crying detection and high-decibel detection. That means real notifications for a baby crying, breaking noise or a person entering — with fewer alerts from pets or shadows.
Can I speak through it, and what is the Action Touch button?
Yes — built-in mic and speaker give two-way audio (G.711U/G.711A, 64 Kbps, 8 kHz sampling) for talking with family or staff. The Action Touch button on the camera adds a one-press physical control on the unit itself, handy for household members without the app.
How long does a MicroSD card last in this camera?
It takes cards up to 512 GB. The 3MP (2304×1296) main stream is capped at 2048 Kbps, which works out to roughly three weeks of continuous recording on a full card; U-code smart encoding or event-based recording extends that. ANR re-syncs footage after network drops.
Is the Uho-S3E-M3TD-A also available with a 2.8 mm lens?
Not according to the official datasheet, which lists one fixed 4.0 mm F2.0 lens (67.3°) for the Uho-S3E-M3TD-A. The only 2.8 mm model in this S3E 3 MP family on our site is the Uho-S3E-M3F3-A, which has IR only and no warm light or Action touch button. If you need a wider view with the TD features, look at the Uho-S3E-M5TD-A (84.0°).
What do I get with the Uho-S3E-M3TD-A that the Uho-S3E-M3-A does not have?
Three things: a 10 m warm light beside the 10 m IR (Dual Light mode), the Action touch button on top for calling and privacy mode, and a Wi-Fi 6 radio (802.11ax, 20/40 MHz) instead of 802.11b/g/n. The image is the same: 3 MP, 4.0 mm, 67.3°, 355° pan, 20 presets and auto tracking on both. Power is similar at max 5.5 W versus 5.6 W.
Will the warm light on the Uho-S3E-M3TD-A wake a sleeping baby or disturb people at night?
It can, because warm light is visible light. For bedrooms use the IR mode: the 850 nm IR shows only a faint red glow at the emitters and gives a black-and-white picture up to 10 m. Keep the warm-light behaviour for presets that watch a living room, hallway or shop, where a visible light is useful.
How does auto tracking on the Uho-S3E-M3TD-A behave, and when should I turn it off?
When it detects a moving subject it pans and tilts at 17°/s to 50°/s to keep it in frame, so a person walking across the room is followed smoothly; fast movement right in front of the lens can escape it. Pets, a robot vacuum or moving curtains can also pull the view away, so in homes with animals limit alerts to the human class or turn tracking off. Turn it off too when one spot, such as a cash drawer, must stay in view all the time.
Can the Uho-S3E-M3TD-A warn off someone entering my shop at night?
Partly. Human detection sends a push alert, auto tracking keeps the person in view, and you can speak through the built-in speaker from the app. According to the datasheet, Dual Light mode switches between IR and warm light when a preset is triggered, which gives a color image and a visible light; set up and test in the app which event calls that preset. There is no siren or alarm output (Alarm I/O is N/A), so it is a deterrent, not an alarm system.
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.
Can the Uho-S3E-M3TD-A be used outdoors or in an open garage?
No for outdoors: it is an indoor camera with no IP weatherproof rating in its specification. Its working range is -10 °C to 50 °C at up to 95% RH non-condensing, so a closed, dry garage within that range is fine, but not a spot exposed to rain, splashes or condensation. For outdoor coverage choose an IP66/IP67 model.
What USB-C power supply does the Uho-S3E-M3TD-A need?
A 5 V adapter rated 1.5 A with a USB Type-C cable, as the spec states (DC 5 V/1.5 A). Maximum consumption is 5.5 W, which is 5.5 W ÷ 5 V = 1.1 A, so a 5 V 1.5 A adapter covers the peak with margin. A 5 V 1 A charger (5 W) is below that peak and can cause restarts when the motor and lights run together.
Should I choose the Uho-S3E-M3TD-A or the Uho-S2E-M3-A?
Choose the Uho-S3E-M3TD-A if you want color images at night or a wider movement range. Both are 3MP indoor pan-tilt cameras with a 4.0 mm lens, auto tracking and two-way audio, but the S3E-M3TD-A adds dual light (IR + warm light, 10 m), Wi-Fi 6 (802.11ax), USB-C power and 355° pan with -15° to 90° tilt. The Uho-S2E-M3-A has IR only, 802.11b/g/n Wi-Fi, Micro USB power, 338° pan and -5° to 55° tilt, which is enough for basic indoor monitoring.
Does the Uho-S3E-M3TD-A need a Wi-Fi 6 router, and can it connect by cable?
No Wi-Fi 6 router is required: it supports IEEE 802.11b/g/n/ax on 2.4 GHz, so any 2.4 GHz router works, and an 802.11ax router allows up to 270 Mbps. 5 GHz is not supported, and security is WEP or WPA-PSK/WPA2-PSK. It also has one 10/100 Mbps RJ45 Ethernet port, and integrates via RTSP, API and SDK, with the APP or Uniarch client for setup.
