AF28 (2.8 mm, 97° view) covers a wide area near the camera — doorways, small rooms, shop counters. AF40 (4.0 mm, 79° view) trades width for reach — corridors, driveways, fence lines. 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.

Shops & storefrontsSee who enters, and the built-in mic records what is said at the counter. AF28 covers the whole shop floor from a corner.

Home gates & yardsSmart IR turns on at night for discreet black-and-white night vision — the camera watches without lighting up the scene.

Warehouse & site perimetersIP67 body and −30 to 60 °C rating survive rain, dust and heat. AF40 watches long fence lines.

Sites needing local backupA built-in MicroSD slot keeps footage on the camera itself — useful as a backup even where an NVR is also recording.

Small offices & receptionUltra 265 compression keeps recordings small — more days of footage on the same NVR disk.

Kiosks & fuel stationsOne PoE cable does power + video — no electrician needed at the pole, quick to install and move.

Not the right pick if you need…

Full-color night vision — this is IR-only, night video is black & white, not color
Two-way talk — it has a mic but no speaker
Wi-Fi — this is a wired RJ45 camera
Zoom — the lens is fixed (2.8 or 4.0 mm, chosen at purchase)
Alarm in/out wiring for sirens or sensors
