安防計算機

Description

When you need real-time calculations in the basement or elevator, the program can be calculated completely offline, without the need for an Internet connection, and the results can be provided immediately for user reference, and can distinguish between H264 and H265 formats.
1. Hard disk calculation: The total amount of hard disk required, the daily volume and the average bit rate can be calculated through parameters such as the number of lenses, recording days, bit stream selection, frame size and motion detection.
2. Time calculation: The time and days required for recording can be calculated through parameters such as the number of lenses, hard disk capacity, stream selection, and number of frames.
3. Focal length calculation: The relative distance and recommended lens meter can be calculated through parameters such as object distance and object width.
4. Weights and measures conversion: You can choose length, area, volume, weight, and temperature conversion.
5. Code stream comparison table: Code stream parameters corresponding to each resolution, for example, 1080P resolution is 1920*1080, H264 is 5Mb/s, H265 is 3Mb/s, and Pixel is 2 million pixels
