Key Specifications & Features

1. Camera Type

   • 4 MP fixed dome network camera from Hikvision’s Pro / EasyIP 4.0 series.

   • Version “L” means no built-in microphone; “SU / SL” variants add mic / speaker.

2. Image Sensor & Resolution

   • Uses a 1/1.8″ progressive-scan CMOS sensor.

   • Maximum resolution: 2688 × 1520 (≈ 4 MP).

3. Lens

   • Fixed focal length: 2.8 mm.

   • Field of View (FOV): ~112° horizontal, 61° vertical, 134° diagonal for the 2.8 mm lens.

   • Aperture: F/1.0 (very “bright” lens, good for low light).

   • Depth of field for 2.8 mm: ~2.5 m to ∞.

4. Low-Light / Illumination Performance

   • Very low minimum illumination: 0.0005 Lux (F1.0, AGC on).

   • Has a white-light supplement (built-in) for night / low light.
     Supplement (white) light range: up to ~30 m.

   • “Smart” supplement light: yes — adjusts / manages its light usage smartly.

5. Dynamic Range & Image Enhancement

   • Wide Dynamic Range (WDR): 130 dB, helping with scenes with high contrast (bright + dark areas).

   • Additional image improvements: BLC (Back Light Compensation), HLC (Highlight Compensation), 3D-DNR (Digital Noise Reduction), AWB / AGC, privacy masks, ROI, and mirror function.

6. Video / Compression

   • Video compression support: H.265, H.265+, H.264, H.264+.

   • Supports multiple video streams: main, sub, third stream.

   • Bitrate control: CBR (Constant) and VBR (Variable). (common in Hikvision)

7. Smart / AI Features

   • Deep-learning based human / vehicle classification (smart detection).

   • Smart event support: line crossing, intrusion, region entrance / exit, scene-change detection.

   • Face capture is supported.

8. Network & Storage

   • Power: supports 12 V DC or PoE (IEEE 802.3af, Class 3).

   • On-board storage: microSD / microSDHC / microSDXC (check memory limits from datasheet). (In similar models)

   • Network protocols supported: standard IP-camera protocols. (Hikvision typical)

9. Durability / Build

   • Ingress protection: IP67 (dust-tight and water resistant).

   • Vandal resistance: IK10 (resistant to vandal hits).

   • Operating temperature: approx –30 °C to +60 °C.
     Mechanical / Dimensions

   • Pan / Tilt / Rotate (for camera orientation): Pan 0°–355°, Tilt 0°–75°, Rotate 0°–355°.

   • Lens mount: M16.

   • Weight: ~570 g (for similar 2.8 mm model).

10. Power Consumption

    • 12 V DC power consumption: ~5 W (per spec from Polvision).

    • PoE consumption: ~6.5 W max.
      Alarm / I/O

    • Has 1 alarm input and 1 relay output for external trigger integration.
      Use-Case / Strengths

    • Ideal for outdoor surveillance with tough environmental conditions, thanks to IP67 and IK10.

    • Good for low-light environments, color imaging 24/7 due to F1.0 lens + white light.

    • Suitable for smart security applications: human/vehicle detection, alarms, face capture.

    • By using PoE, simplifies power cabling in installations.
