WV-CL270 series is a high-sensitivity, high-image quality and high-cost-effective 1/2-inch CCD digital signal processing (DSP) color surveillance camera that is designed to allow you to capture images in 0.2 Lux of minimum illumination (When using F0.75 lens). The image output quality is high, with 480 lines of horizontal resolution and 50 dB of signal-to-noise ratio. In addition, a series of other features are included: backlight compensation (BLC), aperture correction and automatic tracking white balance (ATW). This type of camera is ideal for obtaining clear and natural color images in many environments requiring backlighting or low light conditions.
This manual describes the Panasonic WV-CL270 series color surveillance cameras, highlighting high sensitivity, high image quality, and cost‑effective performance. Key functions include back‑light compensation, aperture correction, automatic tracking and white balance, and electronic aperture control, making the cameras suitable for low‑light environments such as retail stores, hotels, and parking lots.
The document also lists detailed technical specifications such as sensor type, resolution, power requirements, operating temperature, and video output options, along with component names and installation notes for both the 220‑240 V (WV‑CL270) and 24 V (WV‑CL274) versions. This manual is written in Chinese.
