Panasonic CCTV CAMERA WV-BP102 - Manual (Page 8)

(G) Electronic Light Control ON/OFF Switch
{ELC ON/OFF)
OFF :
Choose this position used with an auto iris lens.
ON :
Choose this position used with a fixed or
manual iris lens.
See page 6 for more details.
(7) Video Output Connector (VIDEO)
• A 1.0 Vp-p/75 ohms composite video signal is
provided at this connector,
• This connector also receives DC power and vertical
drive pulses for the camera from the video monitor
and sends video information to the video monitor.
(8) 12V DC In Terminal (DC 12V IN)
This terminal accepts 12V DC power source (10,5V
- 16V).
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
following 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 depih 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).
