JVC VN-E4 ACH1 RequestB, Checkbox, JPEG Size Selection, Button, Display Selection, List, Port

Operation (continued)

A	ACH1 RequestB	The viewer will acquire image of the corresponding CH from VN-E4according to boxes that are checked.
	Checkbox	When the checkbox for a channel is deselected, the viewer will not acquire image of this channel
		from VN-E4and the CH button will be disabled. Additionally, no image will be displayed even if
		the checkbox is selected if the corresponding CH and JPEG size on the AEncodingB of the VN-E4
		unit are set to off.
B	JPEG Size Selection	Select either VGA (640 x 480) or QVGA (320 x 240) as the video frame size.
	Button	No image will be displayed even when the size is selected on this screen if this size is set to off
		on the AEncodingB page of the VN-E4unit.
		NOTE:
		Selecting a large frame size will increase the processing load of the PC on which the viewer is running.
		Set to a value such that the load of the PC on which the viewer is running does not exceed 80 %.
C	Display Selection	Select AReverseB to rotate the image display by 180.
	Button
D	Title Selection Button	Select AOnB to display the camera name and time in JPEG file. Camera name can be changed
		on the AInputB page of the VN-E4unit.
E	Frame Rate Selection	For selecting the acquisition frame rate of the viewer.
	List	The frame rate set at the VN-E4unit will be the upper limit to which the viewer can acquire. For
		example, when VN-E4is set to A15 fpsB, transmission will only be possible at 15 fps even when
		the client requests for 30 fps. Alternatively, when VN-E4is set to A15 fpsB and 10 fps is requested
		by the client, data will be sent at 7.5 fps to enable transmission at even intervals. In the case of a
		1-to-1 connection between VN-E4and the viewer, it is recommended that the frame rate of the
		viewer and VN-E4be set to the same value. To play back multiple viewers at different frame
		rates, set the frame rate accordingly at the individual viewer.
		NOTES:
		● When the frame rate set is smaller than that at the VN-E4unit, this will be reflected in the
		frame rate during transmission from VN-E4when acquisition is performed via HTTP.
		● When acquisition is performed via multicast, data volume will not decrease even when a
		frame rate that is smaller than that at the VN-E4unit is set, and the built-in viewer will play
		back images while skipping frames.
		● Selecting a large frame rate will increase the processing load of the PC on which the viewer is running.
		Set to a value such that the load of the PC on which the viewer is running does not exceed 80 %.
F	Alarm Event Selection	When AMakeB is selected, the AAlarmB button will light up when Make occurs in the alarm input of
	Button	VN-E4.When ABreakB is selected, the AAlarmB button will light up when Break occurs in the
		alarm input of VN-E4.
G	Auto Alarm Clear	For selecting the time interval to turn off the light automatically after AAlarmB button is illuminated.
H	Stream Selection	For selecting the protocol when the viewer acquires data from VN-E4.
	Button	When HTTP is selected, packet loss can be recovered by HTTP though number of clients is
		limited. Maximum number of HTTP streams is 10. When AMulticastB is selected, multiple viewers
		can monitor VN-E4 though packet loss causes noise or skip of data. Additionally, start multicast
		sending on the AStreamingB of the VN-E4unit when playing back via AMulticastB.
		When the viewer is launched with AMulticastB specified, a Windows firewall warning may be
		displayed. When this occurs, proceed upon selecting “Unblock”. If “Block” is selected, the
		Windows firewall will block the multicast streams and playback of AMulticastB at the viewer will fail.
I	Multicast Address,	For specifying the multicast address and port number for 4 channel JPEG and audio. This is
	Port	enabled only when AMulticastB is selected in the AStreamB selection. Specify the same value as
		the parameter that is set on the AStreamingB page of VN-E4.
J	Audio Monitor	Select AOnB to enable audio monitoring of VN-E4using the viewer. The viewer will not acquire
	Selection Button	audio from VN-E4when AOffB is selected.
K	Buffering Time	For selecting the buffer volume of the viewer.
	Selection Button	To shorten the delay time, select a small buffer. To ensure stable playback on a network with
		unstable bandwidth and jitter, select a large buffer.
L	Boundary	For selecting boundary lines on the screen.
M	Operator Password	For registering the AoperatorB password of VN-E4.
		Upon registering the password, features of the ASpeech OnB and AControl CH1-CH4Bbuttons
		will be available for use.
N	OK Button	For saving the changed settings. To enable the new settings, exit and restart the viewer.
O	Cancel Button	For canceling the changed settings and closing the setting screen.
