Technical Specifications
Hikvision DS-2CD2043G2-I (4mm) — 4MP AcuSense Fixed Bullet Network Camera
If you’re tired of cameras that “see everything” but alert you for nothing important, this model is built to cut through the noise. The DS-2CD2043G2-I uses AcuSense deep learning to focus on human and vehicle targets—so your motion alerts become useful again, not a constant distraction.
With a 4MP (2688 × 1520) image, 120 dB WDR for harsh lighting, IR up to 40 m for night coverage, and a built-in microphone (-U), it’s a strong “set it and trust it” choice for entrances, drive lanes, and perimeter views.
Key Features
- 4MP clarity (2688 × 1520) — sharp detail that makes reviewing footage faster and less frustrating.
- AcuSense human/vehicle classification — fewer false alerts, more confidence that notifications actually matter.
- 120 dB WDR — clearer faces and vehicles when sunlight or headlights would normally wash the image out.
- 4mm fixed lens (84° HFOV) — a tighter view than wide-angle, great when you want more detail on a driveway, gate, or entry lane.
- IR night vision up to 40 m — reliable coverage after-hours without adding extra lighting.
- H.265+ — saves storage and bandwidth so your NVR/VMS doesn’t fill up as quickly.
- Built-in microphone (-U) — adds real-world context to incidents (voices, impacts, alarms) right in the recording.
- IP67 rated — built for outdoor dust and water exposure.
- microSD support up to 512 GB — local backup recording option for extra peace of mind.

Ideal Applications / Common Uses
- Driveways, gates, and entry lanes — the 4mm view helps you capture more usable detail where it counts.
- Front entrances & back doors — WDR helps when the sun is behind visitors, and the mic adds context.
- Perimeter lines (fences, side yards, loading areas) — line crossing / intrusion detection with human/vehicle classification reduces nuisance alerts.
- Small business exteriors — IP67 durability and PoE make installs cleaner and more reliable over time.
- Parking areas — IR up to 40 m supports night coverage without extra lighting.
Note: The datasheet also includes a general “Typical Application” note that this model has NO SPECIFIC PROTECTION for anti-corrosion environments (i.e., choose accordingly if you’re installing in coastal/chemical/harsh corrosion zones).

Frequently Asked Questions
This camera delivers a maximum resolution of 2688 × 1520, which is classified as 4 megapixels. This level of resolution allows finer detail compared to standard 1080p cameras, making it easier to identify people, vehicles, and objects. The higher pixel density is especially useful when reviewing recorded footage or digitally zooming into a scene. According to the datasheet, this resolution is supported at up to 25 fps (50 Hz) or 30 fps (60 Hz).
The 4mm fixed lens provides a horizontal field of view of 84°, a vertical field of view of 45°, and a diagonal field of view of 100°. This lens option offers a more focused view compared to wider lenses, which helps capture greater detail at longer distances. The datasheet also includes DORI values for the 4mm lens, indicating detection up to 80 m and recognition up to 16 m. This makes the 4mm version well-suited for driveways, access lanes, and perimeter monitoring.
Yes, the camera includes built-in infrared (IR) illumination for night-time monitoring. The datasheet specifies an IR range of up to 40 meters using 850 nm infrared LEDs. When IR is active, the camera can operate at 0 lux, meaning it does not require any visible light. This allows reliable nighttime coverage for outdoor areas without adding external lighting.
AcuSense is Hikvision’s deep-learning-based analytics technology designed to improve event accuracy. According to the datasheet, this camera supports human and vehicle target classification for motion detection. It also supports advanced perimeter protection features such as line crossing and intrusion detection. These functions help reduce false alarms caused by animals, rain, or moving vegetation.
Yes, the “-U” version of this camera includes a built-in microphone. The datasheet confirms support for multiple audio compression formats, including G.711, AAC-LC, and MP3. It also supports audio sampling rates up to 48 kHz and includes environmental noise filtering. This allows audio to be recorded alongside video, adding contextual information to incidents.
The camera supports H.265, H.264, H.265+, and H.264+ compression for the main stream. Sub-streams also support MJPEG in addition to H.264 and H.265. According to the datasheet, H.265+ and H.264+ help reduce storage and bandwidth usage while maintaining image quality. This is especially beneficial for long-term recording on NVRs or network storage.
Yes, the camera includes a built-in microSD card slot for onboard storage. The datasheet specifies support for microSD cards up to 512 GB. This allows the camera to record locally as a backup or standalone solution. It also supports network storage options such as NAS using NFS or SMB/CIFS.
The camera is rated IP67 according to the datasheet, meaning it is protected against dust and water ingress. It is designed to operate in temperatures ranging from -30 °C to 60 °C (-22 °F to 140 °F). These specifications make it suitable for most outdoor environments. However, the datasheet notes that it does not include specific anti-corrosion protection.
The camera can be powered using either 12 VDC or Power over Ethernet (PoE). PoE is supported under the IEEE 802.3af standard, Class 3. Maximum power consumption is listed as 6 W using 12 VDC or up to 7 W when powered by PoE. This flexibility simplifies installation by allowing a single Ethernet cable for both power and data.
The datasheet lists the DS-1280ZJ-XS junction box as an optional accessory. This junction box can be used to protect cabling and provide a cleaner installation. The camera itself supports pan, tilt, and rotation adjustments for flexible positioning. No additional accessories are listed directly in the provided datasheet.
