Video Output Colour/Mono Mode
The video output is set to Colour by default. Set it to Mono for video output in monochrome or to C/M
for colour in normal light and monochrome in low light.
Fluorescent Lighting
Under some types of fluorescent lighting, the colour may cycle. Set Fluorescent to On to help reduce
this. Alternatively, line-lock may reduce this problem (see Using AC Line Lock below).
ON
Reduces colour rolling that may occur under some types of fluorescent lighting. For best results, line
lock synchronisation is recommended. If line lock synchronisation is not possible, an auto-iris lens
should be used.
OFF (default)
The default setting maximises dynamic range
Synchronisation
Using AC Line Lock
The line lock (LL) Sync settings of LL-Phase 1, LL-Phase 2, LL-Phase 3 and LL Manual are for use
when the video output of the camera needs to be synchronised to lighting (to reduce colour cycling),
or other video equipment (to eliminate picture rolling).
As line lock (LL) uses the frequency and phase of the 24V AC camera power to keep the video
synchronised, it is not available when connected to a DC supply.
Line-lock (LL) settings LL-Phase 1, LL-Phase 2, LL-Phase 3 are used to synchronise multiple
cameras across a distributed site where different mains electricity phases are used. Each of the
three settings has a 120° offset from the last; where 360° is equivalent to one frame of video
To minimise picture roll:
1 At the camera, select LL-Phase 1
2 At the central monitor (not the local monitor), test the setting by switching the video
display between other video sources and the camera and observing the picture roll.
3 Repeat with settings LL-Phase 2 and LL-Phase 3 until picture roll does not occur
Note: Line lock synchronisation can interfere with on-screen displays. In these circumstances
set the camera to Internal synchronisation.
Where the preset phase settings do not align the phase exactly with other equipment, the LL-Manual
setting provides a continuous variation of the picture phase.
Manual Line Lock
LL-Manual allows synchronisation to be adjusted by changing the video line offset in increments of
1. This allows for continuous phase adjustment over a complete video frame.
To set LL-Manual: Press B to increment the line number by 1. Hold down B to continually increase
the line number. Hold down A to continually decrease the line number
For your guidance this table shows equivalent phase settings:
Phase PAL lines NTSC lines
0 or 360° (LL-Phase 1) 0 or 624 0 or 525
120° (LL-Phase 2) 208 175
240° (LL-Phase 3) 416 350
Setting the Camera Language
Press button A until Language is selected and then press button B to select the language for the
menu system from English, French, German, or Spanish.
