Key features at a glance
- 4 MP resolution:2688 × 1520 at up to 30 fps for detailed daytime and nighttime images.
- AcuSense deep‑learning:human and vehicle classification to reduce false alarms from animals, leaves or lighting changes.
- Wide field of view:2.8 mm fixed lens with approximately 103° horizontal FOV for broad coverage.
- Built‑in microphone:onboard audio capture with multiple codecs for contextual sound recording.
- Robust outdoor design:IP67 weatherproofing, IR illumination to 30 m and a wide operating temperature range.
- Flexible power & storage:PoE (802.3af) or 12 VDC power, microSD card slot up to 256 GB and NAS support with ANR.
Detailed specifications and benefits
- Image sensor:1/3" progressive scan CMOS providing true progressive capture for clearer motion rendering.
- Resolution & frame rate:2688 × 1520 (4 MP) at up to 30 fps — a clear step up from common 2 MP cameras, enabling better identification of faces and license plates at moderate distances.
- Lens & field of view:2.8 mm fixed lens, F1.6, ≈103° horizontal FOV. This wide angle is ideal for monitoring driveways, building fronts and small yards with fewer cameras.
- Low‑light and WDR:minimum illumination of 0.005 lux at F1.6 in colour, plus 850 nm IR illumination to 30 m and 120 dB WDR. The combination helps retain image detail in difficult lighting such as backlit entrances or partial shadows.
Benefit: the 4 MP image plus wide FOV balances detail and coverage. For many outdoor areas you’ll capture more useful pixels per scene without the bandwidth and storage cost of higher‑megapixel sensors.
- Advanced codecs:H.265+/H.265/H.264/H.264+ support reduces bandwidth and storage compared with older codecs, especially when using Hikvision’s H.265+ efficiency optimisations.
- Multi‑stream:main, sub and third streams plus SVC support let you tailor streams for local recording, remote monitoring and mobile viewing simultaneously.
- Protocols & standards:ONVIF Profile S/G support, TCP/IP, RTSP and HTTPS make the camera interoperable with many NVRs and VMS platforms; RJ45 10/100Base‑T interface is standard.
Benefit: H.265 compression and multi‑streaming reduce ongoing operational costs (storage and network traffic) while maintaining flexibility to integrate with third‑party systems.
- Built‑in microphone:supports codecs such as G.711, G.722.1, G.726, MP3 and AAC with sampling up to 48 kHz — useful for capturing contextual audio.
- Edge storage:microSD up to 256 GB and NAS (NFS, SMB/CIFS) support, with ANR (automatic network-recovery recording) to avoid gaps during network outages.
Benefit: onboard audio adds situational awareness — for example, detecting raised voices or machinery noise — and local storage options provide redundancy for continuous recording.
- Power:12 VDC or PoE (802.3af); typical power consumption ≤7 W depending on IR use.
- Housing:compact turret form factor (Ø127.3 × 95.9 mm) that’s easy to mount on walls or ceilings and less obtrusive than many bullet cameras.
- Durability:IP67 ingress protection and operating range from −30 °C to 60 °C with up to 95% non‑condensing humidity.
Benefit: PoE simplifies wiring for many installations and the IP67 rating ensures reliable outdoor use in adverse conditions.
Where this camera excels: use cases and scenarios
For homeowners seeking improved detection and fewer nuisance alerts, the DS-2CD2343G2-IU offers a balance of resolution and wide coverage. The AcuSense human/vehicle classification helps reduce triggers from animals and weather, while the built‑in microphone can provide audio context to motion events (e.g., a delivery knock or a car engine).
Retail storefronts, small office entrances, parking lots and light industrial sites benefit from the 4 MP resolution and IR reach to 30 m. The turret’s unobtrusive profile and PoE support make it easy to add coverage without major aesthetic impact or extra power cabling.
When paired with perimeter rules (line crossing, intrusion detection) and AcuSense filtering, the camera can form part of an effective early‑warning layer that delivers actionable alerts to security staff rather than a high volume of false positives.
In multi‑camera systems, this model serves well as a supplementary camera to cover general areas, building facades or vehicle approaches, while higher‑resolution units focus on lanes or long distances.
Comparison with similar products
When evaluating the DS-2CD2343G2-IU, it helps to compare by capability and price tier.
Compared with typical 2 MP (1080p) outdoor cameras, the 4 MP Hikvision delivers noticeably more detail — particularly useful for identification tasks — while its price point remains accessible. The wider field of view and better resolution mean fewer cameras may be needed to cover the same area.
High‑resolution 4K or 8 MP cameras provide much greater pixel density for long‑range identification but require more bandwidth, storage and often higher cost. The DS‑2CD2343G2‑IU is positioned as a practical middle ground: higher detail than 2 MP, but more affordable and easier to manage than ultra‑high‑resolution models.
Within Hikvision’s portfolio, AcuSense models are specifically tuned for AI‑based human/vehicle classification. Other Hikvision variants might prioritise colour‑at‑night (ColorVu) or higher‑end analytics; choose the DS‑2CD2343G2‑IU where intelligent alarm filtering, audio and outdoor durability at a modest price are priorities.
At a suggested price of about $129.95, this camera offers a competitive mix of features — AI classification, built‑in audio, PoE and strong low‑light performance — that is attractive for cost‑sensitive projects that still require modern capabilities.
Customer impressions and installer feedback
No individual customer testimonials were provided with the product data. Based on common installer and end‑user feedback for cameras with similar feature sets, typical impressions include:
- Installers appreciate the PoE option, compact turret form and IP67 rating for quick outdoor installs with minimal cabling.
- End users often note the benefit of AcuSense classification in reducing nuisance alerts, which lowers the time spent reviewing false alarms.
- For smaller deployments, buyers value built‑in audio and microSD recording as low‑cost redundancy when an NVR is not present.
These generalized observations reflect the practical benefits customers expect from combining 4 MP resolution, AI filtering and straightforward networking — but prospective purchasers should review real user reviews and trial the device in their environment where possible.
Considerations before buying
- Confirm compatibility with your NVR or video management system; although ONVIF support helps, feature parity (e.g., AcuSense metadata) may be vendor‑dependent.
- Check local regulations for audio/video recording and ensure you have appropriate consent and signage where required.
- Plan mounting location to make best use of the 2.8 mm wide field of view—this lens sacrifices long‑range detail for breadth of coverage.
- Factor in storage strategy: H.265+ will reduce storage needs, but retention targets and number of cameras determine total disk requirements.
Conclusion: why the DS-2CD2343G2-IU is a strong choice
The Hikvision DS-2CD2343G2-IU 4 MP AcuSense turret camera offers a pragmatic blend of resolution, intelligent alarm filtering and audio capability at an accessible price point. Its PoE support and IP67 rating simplify installation for residential and small‑to‑medium commercial applications, while the AcuSense human/vehicle classification significantly reduces nuisance alarms — a major operational advantage for many users. For projects that need reliable outdoor coverage, reasonable identification capability and modern compression to keep storage costs down, this camera represents a well‑balanced option. As always, verify compatibility with your recording and monitoring systems and consider a site survey to match lens, placement and retention needs to your security goals.
