Lens initialization
Set the duration between automatic camera lens initializations
(Figure 25). During lens initialization 27X and 37X cameras will
zoom in and zoom out while displaying "Lens Init" on the video
screen. This is a normal function that is performed in order to
maintain lens focus accuracy over prolong periods of time.
When you set the lens initialization time and then reset power to
the PTZ, the lens initialization will trigger at the set time.
However, if the PTZ is not power cycled after setting the lens
initialization time then the lens initialization time will trigger any
time within the last hour of the timer setting. For example, if the
lens initialization time is set to 4 hours and power is not cycled to
the unit, the lens initialization may trigger any time between three
hours one minute and three hours 59 minutes. In other words, lens
initialization time occurs any time within a one hour window of
when it was set regardless of the time interval selected.
If you are running a ShadowTour, lens initialization every 24
hours is recommended.
• Select option 1 to initialize the lens manually (Default).
Manual initialization works only if you are using a
KTD-405 keypad and press the key sequence Esc (hold)
and Alarm.
• Select options 2 to 5 to set the duration between
automatic lens initializations.
