j) Frame rate: 1 channel 25f / S (), 30F / S ()
k) Output code rate: 20Kbps - 2Mbps
l) Supporting multiple video mode: one channel 1 - 25 frames / second (),
1 - 30 frames / second () adjustable
m) Recording frame rate is between 1 - 25 frames (), 1 - 30 frames ()
adjustable
n) Video code rate could be chosen between the range from 20Kbpx to 2Mbpx
o) Supporting CBR / VBR working mode, the maximal
variable bit rate peak value could be set up, under the VBR mode, code flow is adjustable
p) Supporting motion detection and object detection with multi - area,
multi - sensitivity
q) Supporting double - coding flow function, LAN transportation delay is
less than 0.5 seconds
r) PSQH series V / A compression card is a professional digital
surveillance product using H.264 compression algorithm
s) PSQH series V / A compression card uses pure hardware technology to do
real time video coding, motion video previewing, motion detection
t) The video images and compressed code flow is transferred to displaying
memory via compression card, no need of the CPU intervention,
greatly saves the CPU resources.
u) ChengFeng innovates the technology of double - coding flow: one flow
for local machine data storage, it greatly improves the net transportation
effects, another one flow is used for
transferring on the net, the delay from the main monitoring server to the client
end is less than 0.5 seconds.
v) The client end could preview with QCIF / CIF format
w) It greatly improves the practicability for networked DVR, and also
PSQH series card could be combined with ChengFeng's hardware decoder
to output the signal to analog monitor, this enables the TV wall
monitoring application
x) Supporting original image capturing, could be saved with BMP format,
the image is with high resolution
