Features:1) H.264 (MPEG-4/part 10) video compression standard leads to high compression ratio and good video quality2) OggVorbis audio compression standard, with 16kHz sampling rate and 16kbps output bit rate3) Real-time video and audio compression, no frame loss4) 4CIF preview resolution5) Complies with PCI 2.2 standards: one PC can support up to 64 channels6) Supports Windows 2000 / XP and Linux operating systems7) Less than 1 second delay in LAN8) Settable IBP frame sequence9) Settable video quality and bit rate10) Settable brightness, contrast,saturation and hue of video signal11) Supports motion detection12) Supports watermark technology13) Supports double encodingAdvantages:H.264 encoding has the advantage of high image quality, low bit rate and low storage requirements, and is especially suitable for digital video security.The 4004HC board is a state-of-the-art video/audio compression board, which uses H.264 ACE (advanced code efficiency) compression.The 4004HC board compression ratio is higher than those that use MPEG-1 or other standards. Given the same amount of hard disk space, the 4004HC board allows for longer recording time, thus reducing storage costs and maintenance expenses and improving system reliability.
