The Uniarch Uho-B1R-M2F3(4)-A 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 ultra motion detection (human/vehicle aware), Smart IR night vision up to 30m, a built-in mic, 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.
- 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
- Two-way talk — it has a built-in mic but no speaker
- 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
Worried about counterfeits? Order under your own company name.
For corporate buyers: we support submitting the purchase order to Uniview under your company's real name — your company appears on the official order, so the origin of the goods can be verified directly with the manufacturer.

Key Features
Complete list from the official datasheet.
Night vision: infrared only
Switchable Auto/Manual IR — set it per site.
Invisible infrared — discreet black & white night vision
Smart IR up to 30 m (98.4 ft.) at 850 nm. The camera watches without lighting up the scene — nothing shows it is recording. This model has a single IR illuminator only, no warm-light module.
How far can it see? (DORI)
DORI (EN 62676-4) is the industry standard for what a camera can do at distance. Switch the lens buttons above to compare.
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.
