surveillance typically refers to fixed installations
designed to perform perimeter monitoring, reconnaissance,
target acquisition as well as other collateral activities.
Fixed cameras can be based on either thermal or visible
imaging technologies, the optimal system depending on
whether the requirement is for detection, recognition
or identification of objects.
for night-time or low-light video recording.
Creates a compact, powerful system that adds
night vision capabilities to most CCTV cameras.
Requires little set up and no calibration or
specialized training. Installs in three easy
steps, and allows the user to retain full control
of the lens iris and zoom.
800 Low Light CCTV
high sensitivity video camera that can be used
for 24-hour surveillance. An EMCCD detector gives
outstanding performance from bright sunlight
to overcast starlight and below. Extended integration
allows imaging at even lower levels with reduced
frame rates. Flexible and easy to use, the camera
offers bright, crisp images in full daylight
while enabling the user to attain optimal performance
at the very lowest light levels. Outstanding
target recognition and identification capability.
Series of Infrared Cameras
on the ATOM series of microbolometer products,
these infrared cameras are ideal for a variety
of security and surveillance applications. Because
of their small size, they are easily integrated
into different system platforms including unmanned
and airborne vehicles. Available in 320 x 240,
640 x 480 or 1024 x 768 array formats.
for large areas (up to 15 acres) and long-range
covert lighting applications. Incorporates
a high power laser diode and patented internal
optical assembly, and delivers the highest
near infrared light output available, while
achieving a Class 1 eye safety rating (IEC-60825-1).
A range of fixed beam widths are available
to meet specific applications. Laser diode-based
illuminators deliver exceptional low life
cycle costs, even illumination. ALS is
a cost-effective alternative to thermal
