Video and Audio

Exposure control - These settings is used to adapt to the amount of light used. Automatic is the default settings can be used in most

situations. The shutter speed is a utomatically set to produce optimum image quality. Flicker-free 50 or 60 Hz is used to remove

ﬂicker which can be caused by ﬂuorescent a nd other light sources. The H old current option l ocks the current exposure settings.

Enable Backlight compensation - Enable this option if a bright spot of light, for example a light bulb, causes other areas in

the image to appear too dark.

Exposure priority - This deﬁnes the balance between image quality and the frame rate. When Motion is prioritized, motion blur

is minimized, but the image quality may be reduce d with a higher frame rate. A prioritized Low noise will provide better image

quality with a lower frame rate.

Overlay

Overlays can be used to provide extra information and are superimposed over the video image. With overlay text it is possible to

include date and time or view the current bit rate as overlay text.

To include the current bit rate as overlay text go to Video & Audio > Video Stream > Overlay Settings,selecttheInclude text check

box option, and enter the code #b in the ﬁeld. See the online help

for supported formats.

Audio Settings

The audio functionality for each video stream is enabled under Video & Audio > Video Stream > Audio.

Audio Input

Input gain - Control the volume (dB Full Scale) of the audio input. If the sound is too low, choose a higher dB. If the sound is too

high, choose a lower dB. The Level bar gives a visual representation of the aud io signal in dB Full Scale.

• Green — the signal is at a good level.

• Yellow — the signal is becoming distorted.

• Red — The signal is distorted

Encoding - Select digital audio encoding format.

• G711 is an unlicensed standard codec that is useful when integrating audio into a VoIP system.

• G726 is an unlicensed speech codec that is most commonly used within the security industry.

• ACC requires a license for both encoding and decoding. AAC is the least complica ted and most widely used codec. If

achieving the best possible audio quality is a priority, A AC is the recommended codec to use. An AAC license is included in

the PTZ Dome Network Camera.

Sample rate - The number of times per second the sound is sampled . A higher sample rate will provide better audio quality, but

also requi res a greater bandwidth.

Bit rate - Set the required bit rate depending on the selected e ncoding. A higher bit rate will give better audio quality. A lower bit

rate ma

y have latency or delay, but will require less bandwidth.
