Panasonic WV-BP120 - Manual (Page 8)

ELC:
Choose this position used with a fixed or man­
ual iris lens.
See page 6 for more details.
(6) AC Power cord
(7) Video Output Connector (VIDEO)
A 1.0 V[p-p] 75Q. composite video signal is provid­
ed at his connector.
(8) AC 24V In Terminal (AC 24V IN)
This terminal accepts 24V AC power source
(19.5V - 28V). Be sure to connect grounding lead
to the GND terminal.
Cautions:
1. Connect this to a 24V AC class 2 power sup­
ply only.
2. To prevent fire or shock hazard, the UL listed
wire VW-1, style 1007 should be used for the
cable for AC 24V Input Terminal.
ELC (Electronic Light Control)
In this mode a continuously variable electronic shutter
is employed to automatically control exposure times in
the CCD Image Sensor, according to the incoming
light level. With this mode selected, fixed or manual iris
lens can be used instead of an ALC type lens.
Cautions:
1. Under bright conditions such as outdoors, use an
ALC type lens as the ELC control range is not wide
enough under these conditions.
2. Under certain unique lighting conditions, the fol­
lowing may appear;
• Strong smear and/or blooming on high light
objects such as spot lights or windows,
• Noticeable flicker on the picture.
Should these phenomena occur, use an ALC lens
3. When using in the ELC mode with a fixed iris lens,
the depth of field of the image may be less than
that obtained by using an ALC lens. Depth of field
varies inversely with the iris opening. Thus, using
this camera in the ELC mode with the fixed'iris
lens fully opened will result in less depth of field
than if an ALC lens was used. (And distant objects
in the picture might not be in focus).
