VEC LC Series video and audio
compression card use Dahua's RISC chip
with hardware H.264 algorithm
compression that reproduces excellent
image quality and achieves high
compression ratio for the best possible
performance and price. This series card
can provide full channels CIF/QCIF with
25/30fps and dual-stream encoding; it
also can support 4CIF(D1)/2CIF with
non-real time encoding or some channels
D1 realtime encoding.
H.264 hardware compression algorithm for
high compression ratio and excellent
image quality.
8/16 channels CIF or 2/4 channels
4CIF(D1) realtime recoding and dual
encoding stream supported, also support
8/16 channels 4CIF(D1)/2CIF/HD1 non-real
time recoding (VEC0804LCN without audio
encoding).
Support 4CIF/CIF/QCIF real-time preview
for up to 64 cameras.
Video detection supports Motion
detection, Video loss and Video block.
Support OSD/LOGO overlay, Privacy
masking, Frame rate and Bit rate
dynamically adjusted etc.
Provide full SDK with Windows and Linux
operation system.
Compatible with full range of Dahua’s
Compression card.
