Hikvision DS-2CC591P-A [7/25] Features

Chapter 1 Introduction

1.1 Features

This series of the camera adopt high performance sensor and advanced print circuit board design technology with

high resolution, low distortion and low noise, etc. The key features as following:

• High performance image sensor CCD, high resolution, capable of providing clear images.

• Low illumination, color/B&W auto switch.

• Backlight compensation

• Auto white balance

• Auto electronic shutter control, adaptive to different environments.

• Auto gain control, with brightness adaptive.

• Advanced technique design, with high reliability.

1.2 Functions

ICR Switch: The camera provides two operation modes: color, and B&W. You can increase sensitivity in low light

conditions by switching to B&W mode (removing the IR cut filter). Color mode is preferred in normal lighting

conditions.

AGC: AGC allows users to adjust the gain of amplifier, enabling the camera to output the standard video signal in

different lighting conditions. As scene lighting decreases, the system will automatically adjust, adding a mixture of

AGC and slow shutter according to the AGC limit setting. In low illumination, AGC will increase camera’s

sensitivity, and output bright and clear video.

S/N ratio: It refers to the ratio between signal voltage and noise voltage. While the ratio is larger, the effect of

noise is less, and the image is more spotless.

White Balance: This feature automatically processes the viewed image to retain color balance over a color

temperature range.
