Audio Mode:
You can select Full duplex or Half duplex.
z
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.
z
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.
Video Clip Format:
Select RECORDING compression format H.264 or MPEG-4.
z
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).
z
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.
LED Threshold:
Select LED light On, Off, and Auto.
z
On: Select On will led always work.
z
Off: Select off will disable led.
z
Auto: Select Auto will appear two thresholds, which one is Bright and the other is Dark,
and you can adjust the threshold for led Auto-On and Auto-Off respectively. The Bright
value higher, the led auto-off more easily in the bright environment will be. The Dark
value higher, the led auto-on more easily in the dark environment will be. Both values
range from 0 to 100.
Note: Concerning how to set up the LED alarm function, please refer to the CHAPTER 9.7.

z
Text Overlay: Some information can be showed on the display screen, such as Date /
Time and user-defined text. The user defined text could be up to 6 letters, this is usful
for donoting the location or ID of the IP camera.And the background color can be
chosen.
z
Privacy Mask: A specific area of the video image can be covered.
