Detailed Specifications and Benefits
- Image sensor: 1/3" progressive-scan CMOS delivering clean, progressive frames.
- Maximum resolution: 2688 × 1520 (4 MP) — more pixels mean improved recognition and cropping flexibility for later review.
- Fixed 2.8 mm lens (F1.6) with approximately 104.3° horizontal field of view — ideal for wider coverage of entrances, yards, parking areas and retail spaces.
- DORI ranges (2.8 mm): Detect 64 m • Observe 25 m • Recognise 13 m • Identify 6 m — useful for planning placement depending on whether you need general motion detection or subject identification.
- Compression: H.265 / H.264 families, including H.265+ and H.264+ — efficient encoding reduces bandwidth and storage costs while maintaining image quality.
- Frame rate: Up to 25/30 fps (region dependent) at full 4 MP resolution for smooth motion capture.
- 120 dB WDR (Wide Dynamic Range): Helps balance scenes with both bright and dark areas (for example, a doorway backlit by sunlight).
- Bitrate range of 32 Kbps – 8 Mbps provides flexibility for network and storage limitations.
- AcuSense deep-learning: Classifies targets as human or vehicle, reducing nuisance alarms caused by animals, shadows or small objects.
- Perimeter protection: Line-crossing and intrusion detection provide actionable event triggers for security systems.
- Face detection: Helpful for event logging and targeted evidence capture when paired with proper storage/management setups.
- Built-in microphone with support for codecs like G.711, AAC-LC and MP3 — allows audio context for events (check local regulations before recording audio).
- Local storage via microSD card up to 512 GB, and NAS support (NFS/SMB) — provides flexible recording strategies including edge storage as a redundancy.
- Network: RJ45 10/100 Mbps and 2.4 GHz Wi‑Fi (W model), ONVIF Profile S/G compatibility, and support for Hik-Connect, iVMS-4200 and Hik-Central clients for remote access and management.
- Power options: PoE (802.3af) simplifies cabling for new installs; 12 V DC supports retrofit scenarios.
- Power consumption: Typically 6–7 W depending on usage.
- Operating range: −30 °C to 60 °C and humidity ≤95% non‑condensing — suitable for most outdoor climates.
- Ingress / impact: IP67 weatherproof and IK08 vandal resistant for longevity in exterior installations.
- Compact physical size: Ø110 mm × 57.4 mm and about 380 g — unobtrusive on facades or soffits.
Use Cases and Ideal Scenarios
Thanks to its balance of image quality, analytics and durability, the DS-2CD2543G2-IWS fits many real-world deployments:
- Residential properties:Monitor driveways, front doors, backyards, and property perimeters with clear day/night imaging and false-alarm reduction through human/vehicle classification.
- Small retail stores and offices:Use the camera to monitor entry points, storefronts and parking bays. Face detection and audio can provide additional context for incidents.
- Multi-site small businesses:Remote management via ONVIF/Hik-Connect and local microSD redundancy make this a sound choice for branches needing reliable, low-maintenance surveillance.
- Perimeter monitoring:Line crossing and intrusion alarms are especially useful for gates, fences and loading yards where early detection matters.
- Installation flexibility:Choose PoE for neat installations or 12 V DC if PoE is not available; the Wi‑Fi variant simplifies installs where running Ethernet is difficult.
How It Compares to Similar Cameras
When compared with basic 2 MP or older-generation dome cameras, the DS-2CD2543G2-IWS delivers higher resolution, better low-light performance and more sophisticated analytics. Key comparative points:
- Resolution and detail:4 MP gives a visible advantage over 1080p cameras for recognition and forensic review.
- Analytics:Deep-learning AcuSense classification reduces false alarms versus traditional motion-only detection systems, which often require more tuning.
- Compression efficiency:H.265 support helps keep bandwidth and storage manageable compared to H.264-only models at similar resolutions.
- Durability:IP67 and IK08 ratings place it ahead of indoor-only domes or low-grade outdoor housings for exposed installations.
- Versus more premium models:Some higher-end models may offer higher resolutions (e.g., 6–8 MP), multi-sensor arrays or analytics with broader capabilities. The DS-2CD2543G2-IWS, however, offers a strong value proposition for most common outdoor needs—balancing cost, features and ease of deployment.
Customer Feedback and Installer Notes
While specific published testimonials for this exact model may vary, typical feedback for cameras with this feature set commonly highlights several strengths:
- Installers appreciate the PoE option and compact form factor, which reduce installation time and visual impact.
- End users often note improved alarm relevance and fewer nuisance alerts when AcuSense classification is properly configured.
- Many users value the night-time performance and IR range for driveway and perimeter coverage where identification at moderate distances is needed.
- Advice from integrators: pair the camera with a compatible recorder or management platform to get the most from analytics, and test placement to align DORI ranges with your practical detection and identification goals.
