Overview

The Hikvision DS-2CV2041G2-IDW (2.8 mm) is a 4 MP outdoor fixed-bullet network camera designed for easy 2.4 GHz Wi‑Fi installation in residential and light-commercial settings. It supports H.265/H.264 compression, onboard microSD recording, two-way audio (microphone and speaker) and EXIR 2.0 night illumination. The camera features an IP66-rated weatherproof housing suitable for external mounting.

• 4 MP (2560 × 1440) progressive-scan CMOS sensor for clear images and video.
• Built-in 2.4 GHz Wi‑Fi with integrated dual antenna for wireless deployment.
• Two‑way audio via built-in microphone and speaker for real‑time talkback.
• EXIR 2.0 IR illumination — night vision to approximately 30 m (region/conditions dependent).
• On‑board storage — microSD/microSDHC/microSDXC slot (see notes on supported capacity below).
• Weatherproof IP66 housing for outdoor use.

Why choose this camera? Simple Wi‑Fi setup and two‑way audio make it suitable for home security, rental properties and light-commercial sites where wired PoE is not practical. H.265 support helps reduce bandwidth and storage requirements compared with H.264.

Important notes & compliance

• MicroSD support is listed inconsistently across regional datasheets; manufacturers list either up to 256 GB or up to 512 GB — confirm the exact regional SKU/firmware before specifying maximum card size.
• Some specifications (sensor size, minimum illumination, supported SD capacity, firmware features such as Hik-Connect pairing) vary by region and firmware build — always check the official regional datasheet and label for the unit you sell.
• Check local regulations and approvals (CE/UKCA) for sale and installation in your market; firmware/region variants may affect cloud services and pairing behaviour.

Installation & safety

• Mount and seal cable entries to maintain IP66 rating when installing outdoors.
• Use the correct regional power supply (12 V DC is typical; confirm unit label). If in doubt, consult the supplied quick start guide and the official user manual.
• For best performance, place within range of your 2.4 GHz Wi‑Fi network and test video/audio after installation.
