from IP Camera. And you can choose the bit rate from 4.75k to 12.2k. However, the
usage of this codec will cause frame-rate decreasing.
Off: Select Off, audio file won’t be transmitted by IP Camera.
Audio mode:
You can select
Full duplex
or
Half duplex
.
Full duplex:
Select it for simultaneous communication in both direction between the
connected administrator and IP CAM. It means both parties can speak and be heard at
the same time.
Half duplex:
Select it for communication in both directions, but only one direction at
a time (not simultaneously). It means one party begins receiving a signal, it must wait
for the transmitter to stop transmitting, before replying. Therefore, once one party
speak, he can’t hear any voice from the other party, just like the communication by
radio set.
Analog Video Output:
Analog video output is for fast and easy installation. The default
is On and the mode of live view of Client Setting page will be fixed in H.264. If off
chosen, the string option will appear H.264, MPEG-4, and MJPEG.
Video clip format:
Select
RECORDING compression format
H.264 or MPEG-4.
MPEG-4:
MPEG-4 has the advantage of sending a lower volume of date per time
unit across the network (bit-rate) compared to Motion JPEG and therefore provides a
relatively high image quality at a lower bit-rate (bandwidth usage).
H.264:
H.264 provides higher compression rate than MPEG-4. Thus, H.264 can
decrease the bandwidth usage and further apply on 3G. However, H.264 will occupy
more system resources than MPEG-4. As long as the operating system appears
operating difficulties under H.264 format, please change to select MPEG-4.
Night ICR Mode:
Select Auto, Day Mode, Night Mode, Schedule
Night ICR Mode:
IR and ICR can be controlled separately in case the device needs
external IR illuminator. ICR will switch to day or night depending on threshold setting
if the setting is auto ICR mode. ICR control can also be set by schedule, choose
schedule mode and the Schedule icon will show up below.
Switch delay:
ICR will switch delay few seconds to avoid sudden brightness and
darkness. The default setting of switch delay is 10 seconds; use pull-down options to
select proper timing.
Night IR Mode:
Two IR levels can be adjusted according to environment and
distance of target object.IR will switch to on and off automatically depending on
threshold setting if the setting is auto IR mode. IR control also can be set by schedule.
IR Level:
Two IR levels can be adjusted manually according to target distance and
view angle. If you wish to use wide view angle and shorter target distance, please set
level1, otherwise, please set level 2.
