M2F3 (2.8 mm, 103° view) covers a wide area near the camera — doorways, small yards, driveway entrances. M2F4 (4.0 mm, 77.5° view) trades width for reach — long driveways, fence lines, further gates. Highlighted rows in the spec table below show every difference.

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 & yardsUltra motion detection tells people from passing cars and stray animals, cutting false phone alerts to what actually matters.

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
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
