Overview
F series compression card using TI TMS320DM642 DSP chip, loading the H.264 algorithm - a real 4*4 DCT transformation; 1/4 pixel motion estimation for increasing accurate motion compensation and greater coding gain; with superior stability, excellent image quality, and a high compression ratio.
Features
H.264 compression algorithm with high compression ratio and excellent image quality.
Realtime video and audio synchronous compression with no frame loss.
Supports 4CIF realtime preview for up to 64 cameras (VEC0404F supports up to 32 cameras).
Supporting multiple resolution recording: 4CIF, 2CIF, CIF, QCIF; and supports 4CIF recording with 12fps (PAL)/15fps (NTSC) for all channels.
Dual encoding streams supported for flexible network transmission.
Supports variable bit and frame rates.
Provides full SDK and demonstration with source code.
Smart video detection: Motion detection, defined motion areas, camera blanking, video loss.
Smart camera settings: Privacy masking, camera lock, color setting, and title display.
Supports OSD, LOGO, and MASK Overlay.
Supports Windows 2000/XP/2003/Vista and Linux operation system.
Complies with PCI 2.2 standard.
Application
Recommended installation areas are Securities Companies, Change Booths, Casinos, Pawnshops, Jewelers, Galleries, Exhibition Halls, Department Stores, Convenience Stores, Discount Offices, Hospitals, Police Stations, Subway Stations, Airports, and Banks etc.
