CONFIGURE THE ENCODING TAB

This tab is available only on encoder units.

Figure 52. Encoding Tab for PelcoNet Device

PelcoNet 3xx encoders support dual MPEG-4 streams that can be conﬁgured to different quality settings. Typically, one stream is conﬁgured for

viewing video, the other for recording. For information on conﬁguring the streams, refer to the appropriate PelcoNet manual.

VMX300(-E) can display multiple digital video windows for viewing the area under surveillance. However, the number of digital windows that can

be displayed at one time is limited by the size and type of images selected for viewing. Refer to Table B for an overview of the CPU workload and

bandwidth amounts used for each type of video stream (the video in a custom window). This table also includes a recommended maximum

number of streams for each type.

Stream 1: Enter the maximum number of MPEG-4 primary streams you want the encoder to transmit at one time in the Stream 1 ﬁeld.

The default setting is the maximum number of MPEG-4 streams the encoder is capable of transmitting (without multicasting).

To limit bandwidth utilization, reduce the setting below the maximum.To display Stream 1 in a custom window, the window’s

canvas must be conﬁgured to display the MPEG-4 signal type.

Stream 2: Enter the maximum number of MPEG-4 secondary streams you want the encoder to transmit at one time in the Stream 2 ﬁeld.

The default setting is the maximum number of MPEG-4 streams the encoder is capable of transmitting (without multicasting).

To limit bandwidth utilization, reduce the setting below the maximum.To display Stream 2 in a custom window, the window’s

canvas must be conﬁgured to display the MPEG-4 Secondary signal type.

For instructions on conﬁguring the a canvas to display MPEG-4 steams, refer to Add a New Canvas (PelcoNet).

This feature is available only if your network supports IP multicasting.

To conﬁgure multicast settings through VMX300(-E), complete the following steps:

1. Click the Mode ﬁeld, and then select the type of stream you want the encoder to multicast from the drop-down box.

2. Enter the IP multicast group address.

3. If the encoder is conﬁgured to multicast one or more MPEG-4 streams, enter the IP multicast group MPEG-4 port(s) in the Stream Port ﬁelds.

4. If the encoder is conﬁgured to multicast one or more MPEG-4 streams, enter the IP multicast group audio port.

NOTE: If a NVR300 Series network video recorder is being used to record video from this encoder, you should subtract a stream from the

total number of streams entered on the Encoding tab. For example, if you would normally transmit one primary stream and ﬁve secondary

streams, and you record the secondary stream, then you should enter 1 in the Stream 1 ﬁeld and 4 in the Stream 2 ﬁeld.
