yushi 3 million-pixel hd network camera ipc331s-ir3-f40-dt

1. Core picture quality and night vision capability 📹

• 3 million ultra-high definitionAdopt high-performance CMOS sensor with a resolution of 2304×1296Compared to traditional 1080P (2000,000 pixels), it offers richer picture details and allows for the observation of more subtle features.
• H.265+ Intelligent CodingThis is one of its major highlights. Utilizing the latest generation H.265+ encoding technology, it ensures clear picture quality while compressing video file sizes to as little as one-third to one-tenth of the H.265 standard. This means thatThe same hard drive can store longer video recordings.or consume less network bandwidth at the same picture quality。
• Powerful Night Vision (IR3)The 'IR3' in the model usually indicates its infrared capabilities. It is equipped with high-power dot-matrix infrared LED lights.Night vision range up to 30 metersWith the ICR infrared filter automatic switching technology, the color is true during the day, and it automatically switches to black and white mode at night, providing unobstructed all-weather monitoring。
• Image Optimization TechnologySupportSmart IR（Preventing Night-Vision Overexposure）Intelligent 3D Noise ReductionNoise Reduction"，"和"翻译成英文是"andWide Dynamic RangeEnsure that the picture remains clear even in complex lighting conditions.。

2. Lens and Perspective 🔍

• Fixed Focus Lens (F40)"F40"通常指的是型号中的"F40"。4mm focal lengthThe lens.
  • Field of viewAround about80°-90° Left and right.
  • "适用场景"可以翻译为 "Applicable Scenario" 或 "Suitable Scenario"。A 4mm lens belongs to the "golden focal length," which is neither as distorted as a 2.8mm lens nor as narrow as a 6mm lens. It is very suitable for surveillance.A room about 10-15 square meters, a corridor or a doorway.。

3. Intelligent Detection and Alarm 🚨

• ROI Interest Region CodingYou can mark the key areas in the scene (such as the cashier counter, the entrance), and the camera will encode these areas in high definition, while the background is appropriately compressed. This can further save storage space.。
• Multiple Intelligence Alarm：
  • movement detectionThe trigger is set when someone moves on the screen.
  • Area InvasionWhen someone enters the forbidden area you have marked (such as within a fence), the alarm will be triggered.
  • Cross-boundary DetectionWhen someone crosses the caution line (such as climbing over a window), an alarm is triggered.
• Remote PushSupports mobile app management, once an alarm is triggered, WeChat or the app will send real-time push messages, allowing you to immediately grasp any anomalies.。
