<br/>

The tab consists of 5 parts:
<br />
# type of configuration ( [[#Channel settings|Channel settings]] or [[#Image parameters|Image Parameters]]) and its parameters;
# '''viewport''' - to display video from the selected source;
# fields for editing the name and description of the selected channel;
# position to determine the viewport for displaying the selected channel in monitoring mode;
# channel list.

==Channel settings==

To configure the channel it is needed to do the following actions in order to configure the channel (see fig. ''Channel settings.Settings sequence''):
<br />
# select a channel from  the channel list, that you want to configure;
# select the type of configuration- “channel settings”;

===Channels list===

<br />
List of channels, their names, designation and description - clicking on an entry in this list determines which channel is configured at the moment. Settings for each channel are unique and do not depend on the configuration of other channels, except for resolution settings and color space for video capture card, which must be the same for each channel on a particular processor board.
<br />

===Channel parameters settings===

While configuring channels parameters it’s necessary to indicate the [[#Motion direction|motion direction]], the [[#Channel purpose|channel purpose]] and the [[#Source type|type of source]] for receiving the data.

====Motion direction====

'''Direction''' – is a setting used to define vehicles motion directions.

<br />
If motion direction is marked as “entry”, then all the vehicles having plate numbers, recognized on this channel, are considered as entering to the parking lot. Then, operator can allow vehicle to enter to the parking lot. Thereafter, time of parking starts to count down for the vehicle. 

<br />
If motion direction is marked as “exit”, then all the vehicles having plate numbers, recognized on this channel, are considered as leaving the parking lot. Then, operator can allow vehicle to leave the parking. In this case system withdraws money from owner’s balance in accordance to parking time and rate.

<br />
If motion direction is marked as “undefined”, then operator can manually set motion direction of vehicle with recognized plate number.

<br />
Thus, if there are different cameras for object entry and exit, and video flow from these cameras is displayd on different channels, then each channel should have settings “entry” or “exit” appropriatly. Otherwise, when for entry and exit there is only one camera, the direction setting should have “undefined” value.

<br />
<font color="#334F9C"> '''''Attention!'''''</font>
----
<font size="2" color="grey">''Wrong values for this setting may lead to uncorrect system work. For example, if motion direction of channel is set as “entry”, and really this channel is on exit, then after number plate recognition system will display red alert, which means some type of error.  Detailed description of system messages for entries and exits read in “Events” tab manual. ''</font>

====Channel purpose====

'''Channel purpose''' – is a setting which is needed to determine the operation mode of the channel.
<br />
:* live - the mode in which the recognition of number plates is not made;
:* parking - the mode in which the recognition of number plate is made, although, an operator should manually allow entries and exits for the vehicles.

<br />
<font color="#334F9C"> '''''Attention!'''''</font>
----
<font size="2" color="grey">''As there is no number plates recognition in “live” mode, so there is no time and parking cost evaluating.''</font>

====Source type====

'''Source type''' - is a setting which determines how the video flow and the parameters of its transmission are transferred to the system.

===Channel name and description=== 

The channel name and its description are intended to facilitate the work of operators. For example, specifying the location of the camera in future could greatly accelerate processing of information by the operator; since he will not have to guess from which camera the image was received.

===Viewport’s selection===

When choosing the '''viewport''' for display on the "Live" tab one should pay attention to the following notation:
<br />
:* gray '''viewport''' - free, can be selected to display the video flow;
:* green '''viewport''' - selected at the moment to display the video flow;
:* red '''viewport''' - is in use by another channel, can not be selected to display the video flow.

If the setting is done correctly, then the following changes will occur on the tab “Channel Settings” (fig. ''Channel settings. Configured channel''):
<br />
:* the name of the channel, the motion direction and its purpose (in case it is specified)  will appear in the upper right corner; 
:* video flow from selected source will appear in viewport for displaying video;
:* channel description and its assignment will appear in the channel list.

===Brightness===

This setting provides software brightness control of the frame that is being recognized. It is recommended to adjust this setting if you know that the object of observation will have a non-standard lighting (shaded or highlighted).

<br />
<font color="#334F9C"> '''''Attention!'''''</font>

<font size="2" color="grey">'' 
Changes of this setting are not visible for an operator; they can be tracked back by frames in the "Events" tab.''</font>

===Contrast===

This setting provides software contrast control of the frame that is being recognized.

<br />
<font color="#334F9C"> '''''Attention!'''''</font>
----
<font size="2" color="grey">'' 
Changes of this setting are not visible for an operator; they can be tracked back by frames in the "Events" tab''</font>

===Threshold===

This setting determines capturing sensitivity. Contrast between the color of alphanumeric signs and license plates depends on the brightness and contrast of the incoming frame. Reducing this setting enables better recognition of dirty plates; increasing this setting allows recognition of clean plates only.  Recommended value — 21.
