SECTION 2: USING THE INTERNET EXPLORER BROWSER
F. MIC: Select this option to send your voice through the microphone on your PC to a speaker connected
to the camera or encoder. Go to SETUP > Video & Audio > Audio to enable the feature and congure
the sound system.
G. PTZ: Click this button to display the PTZ control menu. If your camera has PTZ capability, you can
control the camera through this menu. This button is missing on displays of cameras without the PTZ
feature.
H. DSP: DSP data is shown here. If the data load exceeds 80%, the indicator is red. A high DSP load can
affect the performance of the encoder. For the best performance, normalize the bitrate for both the 1st
and 2nd streams.
Refer to the following for approximate DSP usage. The estimates are based on D1 resolution and 1.5
Mbps bitrate with 1 channel occupied.
— MJPEG 20~25%
— MPEG-4 around 60~65%
— H.264 around 75% ~ 80%
— MD 3%
— VCA 20% ~ 25%
I. OSD (On Screen Display) information: This information shows the current status of the codec. To
adjust the setting, go to SETUP > Video & Audio > Codec.
— Codec: H.264 - Selected codec type for the image
— frametype:
720 X 480 - Resolution of the image
27015 - Data size for 1 frame, calculated by YUY2 format
I or P - Frame type shown alternatively of the moment.
— dts: 4357379.402215 - The Device Time Stamp (dts) showing when the image is encoded
on the server. Initially, camera and encoder clocks start at 00:00:00, Jan 01, 1970.
— bitrate: 1310.516 kbps - Bitrate of the image.
— fps: 6.000 - Current frame per second rate.
— Cache for outbound: 0, 35.374, 5.104
0: This number indicates that 0 frames are waiting to be decoded.
35.374: The current speed of decoding. The normal speed should be 30 ms/frame if the
frame rate is congured at 30 fps. In this example, since 2 frames of 7 frames (currently
sensed fps) are waiting to be decoded, the decoding is being processed at 35.374 ms/fps.
5.104: This number indicates the speed improvement needed for faster decoding
