HD Visible Light Telephoto Camera (OTL- HP VC2075)

Product Overview

The OTL-HP VC2075 HD visible-light telephoto camera employs a 1/1.8-inch CMOS HD visible-light sensor with an effective resolution of 1920 × 1080 (2 megapixels), paired with a large-aperture lens (F3.5–F8.3) and an ultra-long telephoto zoom lens. The overview section gives a focal-length range of 12.5 mm–750 mm and states that the lens features infrared correction.

The source describes the camera as intended for surveillance in remote and complex environments, including coastal defense zones, military bases, railways, forests, oilfields, rivers, and highways.

An internal industrial-grade embedded control electronic system provides control of lens zooming and focusing. The source lists dual optical and electronic fog-removal capabilities and says these can extend visible-light range by up to 1.7× under fog and haze. It also lists image enhancement features including wide dynamic range, backlight compensation, automatic white balance, digital noise reduction, electronic image stabilization, and strong-light suppression.

The source further describes TCS temperature compensation, H.265/H.264/MJPEG compression, and intelligent front-end analysis.

The overview names zone intrusion detection, boundary crossing detection, unattended object detection, entry detection, and exit detection. It also refers to optimized autofocus and auto-exposure algorithms and low-light night-vision capability.

Product’s Highlights:

The large-format high-definition visible-light camera, large-aperture ultra-long-focus lens, and high-magnification optical zoom are described as supporting surveillance in low-light environments and at long distances.

• A high-precision stepper motor unit is described as providing faster and more precise zoom-ratio changes and focusing, with extended service life.
• The intelligent front-end feature list includes mobile detection, zone-based intrusion detection, and boundary crossing detection.
• The source also lists target-behavior anomaly detection, including loitering, prolonged stays, counterflow movement, and clustering.
• An intelligent photoelectric linkage device combined with a dedicated image-processing enhancement algorithm is described as improving image detail in fog, water vapor, and dust.
• TCS temperature compensation is stated to support clear imaging during significant temperature changes.
• The listed video compression formats are H.265, H.264, and MJPEG, intended to reduce bitrate and bandwidth needs for a given image-quality requirement.
• Supported protocol families listed in the source include ONVIF, GB28181, HTTP, RTSP, RTP, TCP, and UDP.
