yushi 2 million pixel hd network camera fixed focus 4/6mm

1. Core picture quality: 20 million full high definition 📹

• Resolution"拥有"的英文翻译是"have"。2 million pixels（1920×1080）, which is the standard high-definition configuration in the surveillance industry. Compared to previous 720P or 960P, it can clearly record facial features, license plate numbers (close-up), and details of the cash register.
• H.265 encodingSupports H.265 high-efficiency video encoding. Compared to the older H.264, it offers the same picture quality at a lower bitrate, resulting in better compression efficiency and lower storage requirements.Saves approximately 50% of hard drive storage space and network bandwidth.This means that by buying the same size hard drive, you can double the time for recording video.

2. Night vision and lens: Practicalism 🌙

• Infrared Night Vision 30 meters (IR3)The model's "IR3" indicates that it is equipped with an infrared array light, with an effective night vision range of up to 30 metersWith the automatic switching of ICR infrared filters, the camera switches to color mode during the day and to black and white mode at night. It can also see contours clearly in total darkness.
• 4mm fixed focus lens (F40)"F40"通常指的是型号中的"F40"，具体含义取决于上下文。例如，在电子产品中，"F40"可能指的是型号、型号代码或特定功能。在汽车中，"F40"可能指的是高性能版本或特定型号。请提供具体的上下文，以便我为您提供更准确的翻译。4mm focal length。
  • Field of viewHorizontal field of view is approximately 80°-90°。
  • Applicable distanceMonitoring distance in3 meters to 10 meters Left and right.
  • Scene SuggestionIt is very suitable for guarding the home, at the entrance of shops, corridors, and other small and medium-sized areas.

3. Engineering and Installation Features (DT Suffix) 🛠️

• PoE (Power over Ethernet) Power Supply SupportThis camera supports standard PoE (802.3af) power supply. This means you only need one Ethernet cable to connect to a PoE switch or DVR, allowing you to solve the problem simultaneously.power supplyandData TransmissionIt does not require additional power cables, greatly simplifying the wiring process.
• IP67 Dustproof and WaterproofThe body design is robust and supports IP67-level protection. Whether installed in indoor ceiling or under the eaves of the outdoor, it can resist the erosion of rain and dust.
• Broad-Voltage InputIt is usually supported by a wide voltage input of DC12V±25%, preventing the device from restarting or being damaged due to unstable voltage.

4. Image Optimization Technology 🖼

• Wide Dynamic Range (WDR)In conditions of backlight (such as directly facing the sun at the entrance), it can balance the bright and dark areas, preventing the face from becoming a 'black face'.
• 3D Digital Noise ReductionAutomatic noise filtering is activated when the light is insufficient to ensure that the image remains clear and free of noise.
• ROI Interested Area：You can set the key areas in the screen (such as the main entrance) for high-definition encoding, and reduce the bitrate for non-key areas to further save hard disk space.
