Camera Specifications

Image Sensor

This camera features a 1/2.5” 8 Megapixel progressive scan CMOS image sensor, providing high-resolution images with effective pixels measuring 3840 (H) x 2160 (V). It is equipped with 512MB of RAM and 32MB of ROM, ensuring efficient performance and storage capacity.

Scanning System

The camera operates on a progressive scanning system, offering smoother and more detailed video footage.

Electronic Shutter Speed

The electronic shutter speed is adjustable both automatically and manually, with a range of 1/3 to 1/100000 seconds, allowing for flexibility in various lighting conditions.

Illumination and IR Capabilities

Minimum Illumination

The camera performs well in low-light conditions, with a minimum illumination of 0.05 Lux at F1.4 in color mode (1/3s, 30IRE) and 0.2 Lux at F1.4 in color mode (1/30s, 30IRE). It can achieve 0 Lux with IR on.

IR Distance and Control

The camera is equipped with four IR LEDs, providing infrared illumination up to a distance of 50 meters (164 feet). The IR function can be controlled automatically or manually.

Lens Specifications

Type and Mount

The lens is motorized with an auto iris (DC) feature and uses a board-in mount type.

Focal Length and Aperture

The focal length ranges from 2.7mm to 12mm, with a maximum aperture of F1.4, offering a balance between wide-angle and zoom capabilities.

Angle of View and Optical Zoom

The horizontal angle of view ranges from 110° to 40°, while the vertical angle of view ranges from 58° to 23°. The lens provides a 4x optical zoom.

Focus and DORI Distance

The motorized focus control allows for a close focus distance of 0.3 meters. The DORI (Detect, Observe, Recognize, Identify) distances are specified for both wide and telephoto settings, providing detailed metrics for surveillance effectiveness.



The camera offers full 360° pan, 90° tilt, and 360° rotation, allowing for comprehensive coverage and flexibility in installation.
