Detailed specifications and benefits
The DS-2CD2143G2-IU packs a number of technical specifications that translate into practical benefits for everyday surveillance needs. Below are the main specification areas and what they mean in real-world use.
- Image sensor:1/3" progressive-scan CMOS producing 2688 1520 resolution. Benefit: clearer stills and more useful detail for identification at medium ranges.
- Lens:2.8 mm, F1.6 with a wide horizontal field of view (~103). Benefit: covers wide entrances and parking areas from a single mount point, reducing the number of cameras required.
- Frame rate:Up to 25/30 fps depending on local mains frequency. Benefit: smooth motion capture which is useful for tracking moving subjects.
- 120 dB WDR:Wide Dynamic Range helps balance bright and dark areas in the same scene, useful for doorways and backlit parking entrances.
- 3D DNR (Digital Noise Reduction):Reduces grain in low-light footage for cleaner images and smaller recordings.
- IR night vision:Up to 30 m (850 nm). Benefit: usable night-time coverage for typical perimeter and access control scenarios.
- AcuSense human & vehicle classification:Uses deep-learning algorithms on the camera to filter out animals, foliage movement and irrelevant triggers. Benefit: far fewer nuisance alarms and lower operator fatigue.
- Video compression:H.265/H.265+/H.264/H.264+ support. Benefit: reduced bandwidth and storage needs while preserving image quality.
- Bitrate range:32 Kbps 8 Mbps depending on settings, scene complexity and compression choice.
- Built-in microphone:Real-time audio monitoring adds context to video events.
- Local storage:microSD up to 512 GB with ANR (Automatic Network Replenishment). Benefit: continued recording if network storage is temporarily unavailable.
- Network compatibility:ONVIF/Profile S plus Hik-Connect and Hik-Central support. Benefit: flexible integration with modern NVRs, VMS solutions and remote apps.
- Security:HTTPS/TLS and IP filtering for secure networked operation.
- Power:PoE (802.3af) or 12 VDC input. Benefit: PoE allows power and data over one cable, simplifying outdoor deployments.
- Power consumption:Max approximately 6.5 W (manufacturer listed).
- Dimensions & weight:Ø121.4 92.2 mm, ≈ 570 g compact dome footprint for discrete installs.
- Environmental ratings:Operating temp 30 °C to 60 °C, humidity ≤95% non-condensing.
- Ingress & vandal resistance:IP67 weatherproof and IK10 vandal rating. Benefit: dependable outdoors in rain, dust and frequent human contact or attempted vandalism.
Use cases and scenarios where this camera excels
The DS-2CD2143G2-IU is versatile and particularly strong where reliable person or vehicle detection, outdoor durability and clear image detail are priorities. Typical deployments include:
- Small business storefronts:Mount near entrances to capture faces and incidents while filtering false alarms caused by shadows or small animals.
- Parking lots and car parks:Wide FOV and vehicle classification help identify vehicle movement and reduce false motion alerts from environmental noise.
- Perimeter and gated sites:Use for fence-line or gate monitoring where IR range and WDR are valuable during mixed lighting conditions.
- Apartment building entrances and lobbies:Dome form factor is discreet and IK10 protection helps guard against vandalism in communal areas.
- Schools, clinics and small campuses:Where reliable audio-visual context and fewer false alarms improve security team efficiency.
Comparisons with similar products in the market
When evaluating the DS-2CD2143G2-IU, consider how its AcuSense intelligence, rugged housing and audio feature set stack up against other options.
- Versus non-AI/standard motion-detect cameras:Traditional motion detection triggers on any movement and produces many false alarms. The AcuSense human/vehicle classification built into this Hikvision model considerably reduces nuisance events, saving time and storage costs.
- Versus similar-resolution alternatives:There are many 4 MP dome cameras from other vendors; what differentiates this unit is the combination of AcuSense analytics, built-in microphone and IK10/IP67 ratings at a modest price point. If analytics are a priority, the AcuSense advantage is meaningful.
- Versus higher-end multi-megapixel or PTZ models:PTZs and higher-resolution fixed cameras offer longer-range detail or pan/zoom control but come at greater cost and complexity. The DS-2CD2143G2-IU is aimed at cost-effective coverage with smart detection rather than extended long-range identification or active tracking.
- Integration considerations:Its ONVIF and Hik-Connect/Hik-Central compatibility make it flexible for use with third-party NVRs and Hikvisions own management platforms; buyers should confirm feature parity (e.g., full analytics support) when mixing vendors in large systems.
Customer testimonials and reviews
There are limited publicised formal customer testimonials tied specifically to this exact model in wide circulation. However, user feedback for cameras in the AcuSense 2xxxG2 family commonly highlights the following themes:
- Fewer false alarms:Installers and end users frequently report noticeably fewer nuisance alerts after switching to AcuSense-enabled cameras compared with earlier models.
- Good daytime image quality:The 4 MP resolution and wide field of view are praised for capturing identifying detail at medium distances.
- Value for money:Small businesses often cite the combination of analytic features, PoE convenience and robust housing as offering solid value relative to alternatives.
- Minor integration notes:Some integrators note that advanced analytics and configuration are easiest when used with Hikvisions NVRs and software, so mixed-vendor environments may require extra testing.
If you need formal testimonials for procurement, seek out installer case studies or request demo units to validate performance in your environment before roll-out.
Conclusion why the DS-2CD2143G2-IU is a great choice
The Hikvision DS-2CD2143G2-IU strikes a practical balance between intelligent analytics, image quality and rugged hardware at a modest price point (suggested price: USD 119.99).
