However, with the capacity of a single hard drive reaching GB or even GB, and most domestic DVRs can already connect 8 GB hard drives, so D1 will gradually become the mainstream. What is the DCIF resolution? The DCIF resolution is the origin of the video image. Why choose DCIF resolution?
The digital surveillance industry puts forward two requirements for digital surveillance products: firstly, it requires low data volume to ensure that the system can record for a long time and stable real-time network transmission; secondly, it requires high definition of playback images to meet the requirements for details. The DCIF resolution can meet the above two requirements on the current hardware and software platform.
Half D1 resolution has been adopted by some products to solve the disadvantages of insufficient CIF resolution, high storage capacity and high price of D1. However, since he is only improving the horizontal resolution compared to CIF, the improvement in image quality is not particularly obvious, but the code stream has increased greatly.
After testing a large number of video signals, based on the current video compression algorithm, DCIF resolution is better than Half D1 to solve the shortcomings of insufficient CIF resolution, high storage capacity and high price of D1. It is used to solve CIF and 4CIF, especially Between Kbps bit rate, stable high-quality images can be obtained to meet the user's requirements for higher image quality and provide better choices for video encoding. The resolution of CIF is not high enough and the storage resolution of D1 is high and the price is high.
The static playback resolution can theoretically reach the image quality of TVline, exceeding the image level of the standard VHS video tape recorder TVline in analog monitoring, reaching the security industry of the Ministry of Public Security.
The definition requirements of the second and third level video standards meet the requirements of most video surveillance. What is D1? Everyone thinks that D1 is the resolution of DVR display, recording, and playback.
Actually, it is not. When comparing megapixel camera specifications you may notice pixel counts slightly different from the above. This is because some cameras will specify the total number of pixels captured by the sensor, and others will specify the 'effective' pixels.
Some of the total pixels are used to contain technical housekeeping type of data, and are not contributing towards the 'effective' details of the image.
