•H.264 compression algorithm using the latest technology, the picture clearer, lower stream / in the compression process used in a variety of patented technologies to ensure the same image quality, the minimum under the stream offers a variety of image processing methods to enhance the signal noise filtering , the picture is more smooth and accurate motion detection technology unique, dynamic image appears automatically when you start recording
•Support I, B, P frames a variety of combinations / quantitative model, image compression ratio greater
•In the compression process, you can dynamically draw frame, can resume at any time to further reduce the storage space
•Preview, compression does not take up CPU time, without disturbing each other, support PAL / NTSC format of the CIF / QCIF
•Can be dynamically set up a variety of video and audio compression precise parameters, to achieve the best audio and visual effects
• Compression rate: 20K ~ 2Mbps, to support CBR, VBR, Hybrid three kinds of bit rate control mode
•Sophisticated, structural stability, ultra-low power consumption, less heat, the system is more stable and reliable
•Optional audio module, support 16bits sampling accuracy of G.72x series of audio compression, to ensure the sound quality
•Image brightness, contrast, chroma, saturation dynamics can be described as
•Support time, text messages and picture LOGO in the video image of the superimposed
•Supports multi-regional, multi-sensitivity of motion detection, motion search precision
•Support for video and audio streams, when the network lining transmission, local area network latency is not more than 0.5 seconds
