Copenhagen open frame camera

The Open frame 12750/336 is an integrated unit, based on a highly sensitive colour CCD camera and a powerful zoom lens, ideal for day / night coastal surveillance, camp perimeter protection, protecting sensitive infrastructures and similar applications.

It is designed to deliver high-performance images, even under the harshest conditions, in temperatures ranging from -40°C to +70°C.

Optical system for long-range surveillance use

The optical system was developed specifically for use in long-range surveillance. It features continuous zoom, with powerful zoom ratio of 30mm to 750mm, auto-iris and focus adjustment from 2.5m to infinity.

The 'auto-focus on demand' lets the camera control the focus by the push of a button.

The lens design incorporates oil-free, low-friction surfaces with special coatings, high-speed motors with zero back-lash and high-precision feedback potentiometers.

This design was chosen with the objective of meeting the highest standards for precision and accuracy and low failure rates. All lens elements are surface coated for high response throughout the visible spectrum.

Stay on target with precise bore-sight retention

The Open frame 12750/336 has factory pre-aligned bore sighting, aligned in parallel with the optical reference axis of the system, which makes for easy on-site installation.

Typical bore-sight retention deviation is ±0.2 milliradians, the equivalent to staying within a target area of 0.2m, at a distance of 1km in NFOV.

External video input / image fusion

In order to reduce the number of channels required for slip-ring transmission, the system can support input from an external camera, such as a thermal imaging camera.

Switching between the daytime camera and external thermal camera can be manual or automatic.

Graphic overlays for image output insertion

The system has a built-in graphic overlay generator that allows arbitrary graphic overlays to be inserted into the image output.

Typical overlays are text strings, showing azimuth, elevation, GPS data or status of weapon systems and symbols, such as hair crosses or other reticles.

Programming the graphic overlay engine is done via the RS-422 (or optional CAN-BUS) interface. Graphic overlays can be customised to suit specific user requirements.

Expanded hi-dynamic range (XDR)

XDR is useful in conditions where there are large variations in brightness in the picture, i.e. when there are very dark and very bright areas in the picture.

XDR amplifies the signal level in dark areas and reduces it in very bright areas, thereby improving the picture's visibility.
