The AutoDome offers all of the features needed for any
indoor surveillance application, from schools to
offices, shopping malls to casinos. AutoDome lets you
focus on details missed by other cameras.
Functions
The revolutionary AutoTrack feature (optional), built
directly into the camera, marks a new generation in
motion detection. AutoTrack not only senses
movement, but zooms in on the target and follows it,
leaving guards hands free for other responsibilities.
Image control and quality are integral aspects of any
outdoor surveillance system. The AutoDome offers
optical zoom lenses from 18x to 26x, and all systems
offer a full 12x digital zoom once the end of the optical
zoom is reached. In addition, the patented scaling
feature ensures that you have optimal control for
viewing at all zoom settings.
Effective surveillance cameras must also perform well
under a range of lighting conditions. To enhance
sensitivity when night falls, the Day/Night AutoDome
automatically switches from color to monochrome by
removing the infrared filter. Whether you program the
camera to switch automatically, or use the manual
switch, the result is optimal camera function, day or
night. For ultimate sensitivity, the B/W camera can be
used. For operation in the darkest conditions, the slow
shutter control feature (standard on all Color and Day/
Night AutoDome cameras) automatically reduces the
shutter speed to as little as one second. This increases
sensitivity by more than 50 times.
To answer concerns about personal privacy, the
AutoDome provides sector blanking and privacy
masking. These features allow customization to ensure
privacy for diverse needs.
Remote control, configuration, and updates can be
performed over the video cable (coax or passive UTP)
when using Bilinx-compatible control and
configuration devices (such as VP-CFGSFT
configuration tool or LTC 8016 Allegiant Bilinx
Interface)
The menu for these devices can display multiple
languages, including: English, French, German,
Spanish, Portuguese and Polish.
The following are some of the features that make the
AutoDome one of the most flexible domes in the
industry. These adjustments can be made by the
installer to customize the AutoDome's operation to
meet a particular customer's needs.
Rugged Bubble (Option)
• Rugged Bubbles are made from 3 mm thick
Polycarbonate, designed to meet stringent strength
standards without compromising optical clarity.
• The Bubble, by itself, can withstand a 100 foot-pound
impact. This energy is equivalent to that of a 10 lb
sledgehammer dropped from a height of 10 feet.
• The Bubble, installed in the Dome, exceeds the
UL 1598 horizontal impact standard for lighting
fixtures, by a factor of 10.
Camera Commands
• Picture quality settings such as White Balance and
Sharpness.
• Max. Gain: When Automatic Gain Control (AGC) is on,
the AutoDome allows selection of a specific maximum
setting that the AGC can achieve, limiting graininess
of the picture. The camera automatically adjusts to
very low-light situations.
• Slow Shutter (Frame Integration): By slowing the
shutter speed, the camera’s sensitivity increases,
resulting in visibility at much lower light levels.
Available settings are fully automatic, or one of six
specific shutter speeds.
• Digital Zoom: A full 12x digital zoom can be utilized
once the maximum optical zoom has been reached. If
digital zoom is not desired, it can be disabled.
Day/Night Commands
• Night Mode: This feature switches the camera from
Color to Monochrome and removes the IR filter, thus
increasing the camera’s sensitivity in low light
applications. Settings are on, off, or fully automatic.
• Night Mode Threshold: When set to automatic, this
feature determines the light level at which the camera
will switch to night mode.
Dome Commands
• Sector Blanking: Video blanking in up to 16 specified
sectors within the total field-of-view.
• Privacy Masking: Up to six areas can be masked from
visibility.
• Guard Tours: There are two styles of Guard Tours:
– The preset tour has capability for up to 99
presets, which can either be included or excluded
from the tour. The dwell time can be specified,
whereupon each of the included presets will be
visited consecutively. This tour continues until
operator intervention.
– Two Recorded tours are available, which have a
combined duration of 15 minutes of movements.
These are recorded macros of an operator’s
movements, including Pan, Tilt, and Zoom
activities, and can be played back in a continuous
manner. This creates a smoother and more
thorough type of automated tour.
• Inactivity: When an operator stops manual control of a
dome, the inactivity option determines what the
dome should do next, if anything. The options are as
follows: return to a specific preset, return to the
automated tour previously executed, or do nothing.
The installer can determine the duration of the
inactivity period.
• Password Control: This feature allows the installer to
determine the security level of dome commands.
Available settings are as follows:
– Low: any user can access any option.
– Medium: a published command unlocks the
commands
[OFF-90-ENTER].
– High: a four digit, modifiable password is
required to unlock the commands.
