Wi-Fi bullet security camera with two-way audio and microSD – HiLook IPC-B140HA-D 2.8 mm

The HiLook IPC-B140HA-D in the 2.8 mm version is a 4 MP Wi-Fi bullet camera for fixed monitoring points where a network cable is not preferred for data connection. It is installed at front doors, garages, side paths, driveways, outbuildings, and under eaves where Wi-Fi setup and local recording inside the camera are more practical than a full wired installation.

The 2.8 mm lens is the wide-angle version of this model. It covers the area in front of doors, short access paths, and smaller yard sections well. The 4 MP resolution delivers more usable detail than basic 1080p cameras and fits residential and small-site installs where activity around the building needs to be recorded clearly.

For low-light scenes, the camera uses EXIR 2.0 with IR illumination up to 30 m. That works well for driveways, side entrances, and garden paths where the scene still needs to stay readable after dark. The IR cut filter handles day and night switching automatically or on schedule.

A key point on this model is two-way audio. The microphone and speaker are built in, which is useful at gates, front doors, side entrances, and garage areas where someone may need to respond directly through the camera. Local recording is handled through a microSD card slot with support up to 512 GB.

The camera supports 2.4 GHz Wi-Fi and also includes an RJ45 port for wired network connection. Remote access is available through the Hik-Connect app. IP66 protects the housing against dust and rain. According to the manufacturer, this model is not intended for sites that require special anti-corrosion protection such as direct coastal or chemically aggressive environments.
