The lens features a 23x optical zoom module with a focal length range from 6mm to 138mm. At the wide-angle end, the horizontal field of view is 58.5°, while at the telephoto end, the field of view narrows down to 3.7°. Switching from wide-angle to telephoto via optical zoom takes approximately 4 seconds. Combined with a 16x digital zoom capability, the system ensures smooth and seamless transitions between near and far scenes.

This camera module boasts exceptional environmental adaptability. In color mode, its minimum illumination level reaches 0.005 lux at F1.6, while in black-and-white mode, it drops as low as 0.0005 lux at F1.6. Paired with an ICR infrared filter that switches automatically, the device ensures uninterrupted operation day and night. The unit is equipped with a 120dB ultra-wide dynamic range and a 3D digital noise reduction algorithm. It also integrates smart image enhancement features such as strong-light suppression, backlight compensation, and electronic defogging. The overall signal-to-noise ratio exceeds 52 dB, effectively addressing challenges posed by backlighting, intense light, rain, fog, and low-light conditions. The electronic shutter speed ranges from 1/1 to 1/30,000 seconds, and the device supports three focusing modes—automatic, semi-automatic, and manual—providing fast and precise focus response. Additionally, it features region-based focusing and exposure control, as well as privacy masking capabilities for up to eight distinct regions. The frame rate is compatible with both 50Hz and 60Hz standards, enabling high-frame-rate output at various resolutions. The device operates on a DC12V ±10% power supply, with a static power consumption of 5.4W and a dynamic power consumption of 10W. Its compact dimensions are 53.3mm × 58.5mm × 96mm, and it weighs only 292g. This small, lightweight design makes it easy to integrate into dome cameras, pan-tilt units, and other devices. The operating temperature range spans from -10°C to 60°C, ensuring stable performance even in harsh environments over extended periods.

II. Professional coding terminal for efficient multi-format streaming of 4K video

The CM204UE encoding and control device serves as the central hub for 4K signal processing and distribution, seamlessly integrating with the KC9423HE to enable video encoding, format conversion, and multi-channel output. The device supports multiple encoding formats including H.264, H.265, and MJPEG, and is compatible with the RTMP live streaming protocol. It can handle signals in mainstream resolutions such as 4K, 1080P, and 720P. The product features true dual-output capabilities via HDMI and IP video, and the video formats of the two outputs can be independently customized, greatly enhancing the device’s flexibility and usability.

The hardware interface includes an HDMI 1.4 port, an RJ45 network port, and a USB 3.0 expansion port. The HDMI port can output video in multiple resolutions, including 4K 2160p at 30/25 fps, 1080p, and 720p. The IP video stream supports up to 4K30 output. The device is equipped with triple-stream technology, with encoding bitrates ranging from 32 Kbps to 16,384 Kbps. Combined with low-bitrate and ROI-based intelligent encoding technologies, it maintains high-quality 4K video while adapting to various bandwidth and storage scenarios. At the network level, the device is compatible with mainstream protocols such as TCP/IP, ICMP, RTSP, and SIP, and complies with the GB28181 standard. It also supports custom OSD and LOGO insertion. Audio is encoded using AAC-LC, enabling synchronized audio-video transmission and full-duplex communication.

III. A full-dimensional interface protocol that empowers 4K system integration and intelligent control.

The rich array of interfaces and universal protocols are key to making the entire solution easy to integrate and maintain. The KC9423HE is equipped with HDMI output and an RS232 control interface, enabling direct connection to PTZ cameras and pan-tilt units, thus expanding shooting possibilities. The day-and-night switching mode offers five options: automatic, color, black-and-white, alarm-triggered, and timed. Additionally, it supports power-loss memory and heartbeat functions, ensuring 24/7 continuous operation of the device.

The CM204UE expands its comprehensive control capabilities by integrating multiple control interfaces, including RS485, TTL, IP control, and IO buttons. It fully supports industry-standard protocols such as VISCA, Pelco D/P, ONVIF, and Visca Over IP, and accommodates various operation modes, including local button control, remote IP control, and serial-port interlinking. Additionally, the device allows for remote firmware upgrades over the network, making it well-suited for modern centralized operations and maintenance management. Both models adopt a unified DC12V power supply standard, resulting in a simple and consistent power architecture that significantly improves wiring, installation, and commissioning efficiency. Whether deploying a small standalone system or a large-scale 4K networked setup with multiple cameras, the devices can be quickly integrated and reliably operate under a wide range of indoor and outdoor conditions.

IV. Full-scenario adaptation and implementation, empowering 4K video upgrades and iterations across various fields.

With its integrated capabilities for acquisition, encoding, transmission, and control, the KC9423HE, in combination with the CM204UE, can comprehensively cover a wide range of 4K application scenarios. In professional broadcasting and live sports event coverage, ultra-high-definition image quality paired with a high-magnification lens and dual-channel output enables simultaneous on-site monitoring and remote streaming. In smart campus and urban security applications, features such as ultra-low illumination, day-and-night switching, and privacy masking—combined with stable network transmission—ensure all-around, round-the-clock high-definition security surveillance. In government and enterprise conference rooms and online teaching environments, the device boasts a compact form factor and easy integration, supports multiple protocols compatible with various central control systems, and guarantees clear and smooth remote 4K audio and video interactions.
