Max Resolution: $2880 \times 1620$ pixels. This is what EZVIZ defines as 3K, and it provides a significantly clearer and more detailed image than standard Full HD (1080p) or even 2K (2560×1440). Both the fixed wide-angle lens and the pan-and-tilt telephoto lens record in this high resolution.

Camera & Lenses:

Dual Lenses: Yes, two independent lenses working together for comprehensive coverage.
- Fixed Lens (Top):
  - Focal Length: 2.8mm @ F1.6
  - Field of View: Diagonal $13 2^{\circ}$ , Horizontal $11 0^{\circ}$ , Vertical $5 8^{\circ}$ . This lens offers a broad, static overview.
- Pan & Tilt Lens (Bottom):
  - Focal Length: 6mm @ F1.6
  - Field of View: Diagonal $6 4^{\circ}$ , Horizontal $5 6^{\circ}$ , Vertical $2 9^{\circ}$ . This lens provides a more zoomed-in view and can be remotely controlled.
Image Sensor: 1/2.7″ Progressive Scan CMOS.
PT Angle (Pan & Tilt Lens):
- Pan: $35 0^{\circ}$ (wide horizontal rotation)
- Tilt: $8 0^{\circ}$ (vertical movement)
Minimum Illumination: 0.5 Lux @(F1.6, AGC ON), 0 Lux with IR (infrared night vision).
Night Vision:
- Black & White Night Vision: Up to 30m (98ft).
- Color Night Vision: Yes, thanks to built-in spotlights. Can achieve up to 40m (131ft) if both lenses point in the same direction. It offers Smart Mode (color on detection), Color Mode (always color), and Black-and-White Mode.
WDR (Wide Dynamic Range): Digital WDR, helps balance exposure in scenes with both bright and dark areas.
DNR (Digital Noise Reduction): 3D DNR, reduces image noise for clearer video.
