The Uniarch Uho-B2D-M3F3(4)D is a 3MP 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 dual-light illumination (20m IR + 10m warm light, switchable), ultra motion detection, two-way audio (mic and speaker), and an IP67 metal-and-plastic body rated for −30°C to 60°C. It is offered with two fixed lenses: 2.8mm (M3F3D, wider view) or 4.0mm (M3F4D, 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 & yardsThe warm light switches on at night for full-color footage of visitors, and two-way audio lets you speak to them directly from the app.

Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat outdoors, day after day. M3F4D 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
Always-on color night vision — full color only shows when the warm light is on (manual or event-triggered); the discreet IR-only mode is black & white
Vandal resistance — the datasheet lists IP67 ingress protection only, no IK impact rating
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

3MP Dual-Light Wi-Fi Camera FAQ — Uho-B2D-M3F3(4)D

What does dual-light night vision actually give me?

You choose per scene: invisible 850 nm IR up to 20 m for discreet black-and-white footage, or warm white light up to 10 m that keeps faces and clothing colors visible — and openly tells people the area is watched. Color starts at just 0.003 lux thanks to the F1.6 lens.

Can I install it without a PoE switch or network cabling?

Yes. The camera joins your Wi-Fi network and powers from a nearby outlet, so there is no PoE switch and no LAN run. With its IP67-rated housing it mounts outdoors on walls or eaves — practical for shops, homes and small warehouses without structured cabling.

Does it support two-way audio?

Yes — two-way audio is supported with G.711U/A compression at 64 Kbps, so you can hear the scene and answer a visitor or warn off an intruder remotely. Audio detection and a tampering alarm can trigger events alongside standard and ultra motion detection.

Which lens option fits my site, 2.8 mm or 4.0 mm?

The 2.8 mm lens sees 108.5° horizontally with DORI detection to 46.7 m and identification to 4.7 m — right for compounds, rooms and yards. The 4.0 mm option tightens to 87.3° and pushes detection to 66.7 m, identification to 6.7 m — better for driveways, gates and passages.

What resolution does it record, and does it need an NVR?

The main stream is 3 MP (2304×1296) at up to 25 fps, with a lighter sub stream for remote viewing; compression is Ultra 265/H.265/H.264 at 128–2048 Kbps. Recordings can go to a MicroSD card inside the camera, so it runs standalone — an NVR is optional, not required.
