M3F3D (2.8 mm, 108.5° view) covers a wide area near the camera — doorways, small yards, driveway entrances. M3F4D (4.0 mm, 87.3° view) trades width for reach — long driveways, fence lines, further gates. Highlighted rows in the spec table below show every difference.

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

Dual Light: two ways to see the night

Switchable Auto/Manual, or auto-switch when a preset is triggered — set it per site.

IR MODE

Invisible infrared — discreet black & white night vision

Smart IR up to 20 m (66 ft.) at 850 nm. The camera watches without lighting up the scene — nothing shows it is recording.

WARM LIGHT MODE

Visible warm light — full-color footage and active deterrence

Warm light up to 10 m (33 ft.) keeps faces and clothing colors visible at night — and tells visitors and intruders the area is watched.
