Detailed specifications and the benefits they bring
- Image sensor: 1/3" or 1/2.7" progressive scan CMOS (varies by production). Benefit: modern CMOS sensors provide good sensitivity and detail at a compact cost.
- Max resolution: 2688 × 1520 (4 MP) at up to 25/30 fps. Benefit: improved image clarity for identification and forensic review versus 1080p cameras.
- Minimum illumination: Colour 0.003 lx (F1.4, AGC on); B/W with IR to 0 lx. Benefit: colour footage in extremely low light—helpful for recognition and situational awareness without relying only on monochrome IR imagery.
- True WDR 120 dB & 3D DNR: Handles scenes with strong contrast (backlit entries, windows) and reduces noise in low light for cleaner images.
- Fixed 4 mm lens (F1.4)with horizontal field of view ≈83. Benefit: a broad scene suitable for entrances, retail aisles and small parking areas without the complexity of varifocal adjustments.
- Smart IR 850 nm, effective to ~30 m. Benefit: even illumination at night with reduced overexposure on close objects and usable range for typical property perimeters.
- Compression: H.265/H.265+/H.264/H.264+/MJPEG. Benefit: efficient H.265 encoding lowers bandwidth and storage use while maintaining detail.
- Bitrate & multi‑stream: 32 Kbps–8 Mbps and multi‑stream support. Benefit: configure a high‑quality main stream for recording and a lower bitrate sub‑stream for mobile viewing.
- Built‑in microphone with audio in/outand support for G.711/AAC/MP3. Benefit: add context to video with ambient sound or two‑way audio on compatible installations.
- microSD support(up to 256–512 GB depending on source/firmware), ANR and NAS (NFS, SMB/CIFS). Benefit: local fallback recording during network outages and options for central archival storage.
- Power: PoE 802.3af (Class 3) or 12 V DC; typical power ≈6.5 W. Benefit: PoE simplifies installation—data and power on a single cable for quick deployments.
- Operating conditions: 0C to 60C and humidity up to 95% non‑condensing. Benefit: suits a broad range of indoor and many sheltered outdoor environments.
- Form factor: Ø121.4 mm × 92.2 mm; weight ≈580 g. Benefit: compact dome that is unobtrusive and easy to mount on ceilings or soffits.
- Ingress / impact: IP67 and IK10 listed by Hikvision. Note: verify reseller/region guidance before exposed outdoor installation and check waterproofing/warranty for your country.
Where this camera excels — use cases and scenarios
The DS-2CD2146G2-ISU(4MM)(C) is well suited to situations that demand a balance of image detail, low‑light colour, and smarter event filtering. Typical applications include:
- Retail stores and shopfronts: 4 MP resolution helps capture faces and product details; AcuSense reduces false alarms triggered by animals or lighting changes; built‑in mic provides audio context for incidents.
- Small to medium parking lots and access control points: DarkFighter and IR coverage support night‑time identification of vehicles and people; PoE simplifies CCTV deployment across lamp posts or light poles where power outlets may be limited.
- Residential and apartment complexes: A compact dome that blends into property exteriors or lobbies, with analytics to reduce unnecessary alerts for leaves or shadows while flagging human and vehicle movement.
- Commercial buildings and small warehouses: Useful for entrance monitoring, loading docks, and interior corridors where variable lighting demands WDR and noise suppression for readable footage.
- Cost‑sensitive projects requiring smart analytics: Offers deep‑learning classification at a mid‑range price point compared with higher‑end cameras that include similar features.
How it compares to similar cameras on the market
Within the mid‑range fixed dome category, the DS-2CD2146G2-ISU(4MM)(C) competes on three main fronts: low‑light performance, analytics, and price. Heres how it stacks up in general terms:
- Versus basic 2 MP domes: The 4 MP sensor captures more detail and allows better digital zoom for identification. If forensic image detail is important, the 4 MP sensor is a clear advantage.
- Versus non‑DarkFighter models: DarkFighters superior low‑light colour performance gives more usable nighttime footage without relying solely on black‑and‑white IR images—useful where color helps identification (clothing, vehicle paint).
- Versus similar analytics-equipped cameras: AcuSenses human/vehicle classification is comparable to other deep‑learning solutions from mainstream manufacturers; the practical benefit is fewer false positives for alarm workflows. Some higher‑end models may offer additional analytics (face recognition, license‑plate reading) that this unit does not include.
- Price and value: With suggested pricing around $149, this camera sits as a value‑oriented option for installers who want better low‑light and analytics than entry‑level models without paying for enterprise features.
Customer feedback and typical reviews
Official user testimonials for this exact model may vary by reseller and region. Based on common installer and end‑user comments for similar Hikvision AcuSense/DarkFighter cameras, typical feedback includes:
- Pros: Very good low‑light color imaging; noticeably fewer false alarms once AcuSense is tuned; easy PoE installation and solid image clarity at 4 MP; compact form factor that mounts cleanly indoors or under eaves.
- Cons or considerations: Verify the exact microSD capacity supported by your firmware/source (specs sometimes list 256–512 GB); confirm outdoor exposure and warranty terms for exposed installations despite IP67 listing; audio quality from built‑in microphones is adequate for context but not a substitute for dedicated audio systems.
- Installer notes: Familiarity with Hikvision firmware and ONVIF setup helps when integrating with third‑party NVRs or VMS solutions. Use recommended network security practices (change default passwords, enable HTTPS/TLS where supported).
Conclusion — why choose the DS-2CD2146G2-ISU(4MM)(C)?
The DS-2CD2146G2-ISU(4MM)(C) is a strong option for users who need a pragmatic balance of image resolution, low‑light color performance and modern analytics at a reasonable price. Its DarkFighter sensor gives better night‑time colour evidence, AcuSense reduces the time lost to false alarms, and PoE plus on‑board recording make deployments straightforward. Whether you are securing a small retail outlet, a parking area or a residential complex, this camera delivers capabilities often found in higher‑priced units while remaining accessible to budget‑minded projects.
Before purchase and installation, confirm region‑specific certification, warranty and recommended environmental usage from your reseller or Hikvision documentation. If your project demands additional analytics (LPR, face recognition) or extreme long‑range optics, consider higher‑tier models; for most general surveillance needs where low light and fewer false alarms are priorities, the DS-2CD2146G2-ISU(4MM)(C) is a practical, cost‑effective choice.
