The Uniarch Uho-B2R-M2F3(4) is a 2MP Wi-Fi bullet camera built for sites where running a network cable isn't practical. It powers from a standard DC12V adapter and connects over built-in 2.4GHz Wi-Fi — no PoE switch or NVR cabling required, just a power outlet nearby. It combines human body detection, two-way audio (mic and speaker), Smart IR night vision up to 20m, and an IP67 metal-and-plastic body rated for −30°C to 60°C. It is offered with two fixed lenses: 2.8mm (M2F3, wider view) or 4.0mm (M2F4, longer reach).

Is this the right camera for you?

Plain-language guide for buyers and installers — based only on what this camera actually does.

Rentals & sites without spare network runsNo PoE switch or NVR cable run needed — plug into any nearby outlet and join the site Wi-Fi. Move it to a new spot without touching a cable.

Home gates & yardsHuman body detection focuses alerts on people approaching, and two-way audio lets you speak to a visitor directly from the app.

Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat outdoors, day after day. M2F4 watches long fence lines.

Checking in from your phonePair it with the Uniarch APP for live view, push alerts and playback from anywhere — no NVR required for basic remote viewing.

Local backup you controlMicroSD edge storage up to 512GB keeps footage on the camera itself — no monthly cloud subscription required to have a recording.

Quick DIY installsNo electrician or cable-puller needed — mount, plug in, and connect to Wi-Fi from the app in a few minutes.

Not the right pick if you need…

PoE power — this camera has no PoE port, it needs its own outlet with the included DC12V adapter
Full-color night vision — this is IR-only, night video is black & white, not color
Vehicle classification — detection here is human-body only, it does not tell people apart from vehicles
A one-time fixed focal length choice at purchase — the lens is fixed (2.8 or 4.0 mm), chosen when you order, not zoomable on site
Rock-solid connectivity regardless of Wi-Fi signal — performance depends on the strength of the site's 2.4GHz Wi-Fi signal at the mounting spot

2MP Two-Way Audio Wi-Fi Camera FAQ — Uho-B2R-M2F3(4)

How is it installed if there is no network cabling on site?

That is exactly what it is built for: it joins your Wi-Fi network and takes power from a nearby outlet, so no PoE switch and no LAN pull. Mount the IP67-rated bullet on a wall or eave, connect power, pair it with your network and it is running.

Can I talk to whoever is in front of the camera?

Yes. Two-way audio is supported with G.711U/A compression at 64 Kbps and echo suppression, so conversations stay intelligible. You can receive a delivery, answer a customer at the gate or verbally warn off an intruder without going outside.

What is the night vision range?

Smart IR reaches up to 20 m (66 ft) at 850 nm — invisible to the eye, so the camera watches without lighting up the scene. The F1.6 lens holds color down to 0.003 lux, and with IR on it records at 0 lux; ICR switching is automatic.

Should I take the 2.8 mm or the 4.0 mm lens version?

The 2.8 mm covers 95.5° horizontally with DORI detection at 46.7 m and identification at 4.7 m — pick it for rooms, small yards and wide entrances. The 4.0 mm narrows to 81.1° but reaches 66.7 m detection and 6.7 m identification — pick it for corridors and driveways.

What detections does it run, and where is video stored?

It runs human body detection, motion detection and audio detection, so alerts focus on people rather than every moving shadow. The main stream records 1080p at up to 30 fps in Ultra 265/H.265/H.264 (128–2048 Kbps), saved to a MicroSD card in the camera.
