Product definition and intended use

The Hetai Tech 4mm is a PTZ CCTV camera with an 8MP Sony STARVIS IMX307 sensor and a fixed 4mm lens. It provides infrared illumination up to 30 metres and stores footage on a micro SD card up to 128G. The aluminium alloy dome supports pan rotation of 0deg-355deg and tilt of 0deg-120deg.

Who this suits and who should look elsewhere

Buyers wanting a 2.5 inch outdoor dome with humanoid detection, tracking and optional linked audio or lighting will find the feature set relevant. Users who require 5X optical zoom at the 8MP resolution should note the manufacturer states this combination is not available. Those needing a varifocal lens or higher zoom at this pixel count must consider a different specification.

Deciding specification: sensor and zoom constraint

The camera uses a 2 megapixel 1/2.8 IMX307 CMOS sensor despite the 8MP option listed in the product option field. The manufacturer highlights confirm 5X optical zoom is only offered on 2MP and 4MP variants. This sensor and zoom limitation is the single detail that determines whether the unit matches the project requirements.
