3.0 DESCRIPTION
Pelco’s TVJ6AC-1 and TVJ6MS-1 are 2/3" format
motorized zoom lenses designed to provide remote
control of zoom, focus and iris functions on the
TVJ6MS-1 lens, and zoom and focus only on the
TVJ6AC-1 lens. These lenses feature color corrected
professional quality optics.
The TVJ6MS-1 is equipped with a tapered neutral den-
sity spot filter as an integral part of the lens to permit
light attenuation beyond the normal range of a zoom
lens down to f360. The spot filter is densest toward the
center and decreases toward the circumference, permit-
ting operation of low-light level cameras in brightest
daylight down to minimum required faceplate illumi-
nation.
The TVJ6AC-1 is equipped with a tapered neutral den-
sity spot filter and internal automatic iris electronics
for fully automatic iris operation on low-light level
CCTV cameras.
Models with the letters “LPP” in the part number are
equipped with potentiometers for the zoom and focus
drive motors, providing a means for preset positioning
commands from a microprocessor based control unit
to automatically drive zoom and focus functions.
