The GC-755N/P is an easy to operate, compact camera. Through the built-in zoom lens, users can monitor images from different perspectives without additional lenses. With DSP technology, intelligent control of automatic aperture, automatic backlight compensation and automatic white balance makes it possible to achieve clear images. In addition, manual remote control zoom and focus are possible through RS-232C/RS-485 connection. All these features, including high sensitivity 1/4-inch CCD, make the GC-755P the perfect CCTV camera.
The GC-755N/P camcorder manual explains how to operate the camera, adjust settings such as focus, white balance, and exposure, and use the on‑screen display (OSD) menus. It also describes the available controls, including zoom, iris, and focus modes, and provides guidance for proper handling and maintenance.
Connection options are covered, with details on RS‑232C/RS‑485 serial interfaces, 14‑pin D‑Sub cables, and power requirements. Environmental limits, dimensions, and technical specifications are listed for reference. This manual is written in Chinese.
