       The camera is equipped with a more stable and long-life industrial-grade 20x optical zoom lens to ensure stable and safe operation of long-term video applications.

      Built-in 1/2.8-inch HD CMOS image sensor with 5 million effective pixels, powerful HD image engine and wide dynamic, high signal-to-noise ratio image imaging algorithm, and unique 2D/3D noise reduction technology, output 1080P60 high Resolution moving image, combined with two high-definition video output interfaces (3G-SDI, IP network), providing simultaneous high-quality image transmission

    With high cost performance and stability, it is ideal for trial recording, educational recording and other video applications.

Features:

□ Built-in 1/2.8-inch HD CMOS sensor with powerful image engine and imaging algorithm to provide full HD experience of 1080P25, 1080P30, 1080P50, 1080P60.

□ Equipped with a high-performance motorized zoom lens with up to 240x zoom (20x optical + 12x digital).

□ Built-in video and audio encoding capability, support H.265/H.264 video encoding and G.711/G.726 audio encoding, enabling 1080p full HD ultra-low bandwidth transmission.

□ Two-way high-definition video output interface (3G-SDI, IP network), providing simultaneous high-quality image transmission.

□ Wide dynamic range, high signal-to-noise ratio image effect, combined with the unique 2D/3D noise reduction algorithm, provides a “quiet and far-reaching” visual enjoyment.

□ Provide three menu controls in English, Simplified Chinese and Traditional Chinese.

□ With zoom position memory, power failure restart function.

□ Equipped with 8 orientation text displays.

□ PELCO-D protocol: 16 preset positions can be controlled and variable to the specified position.

□ Optional infrared remote control for remote control.
