Geutebruck's Argus precision pan and tilt system now with Photon thermal imaging camera

Geutebruck is now offering a thermal imaging camera for its Argus pan and tilt system. Combined with a colour CCTV camera and high speed, precision control, this Geutebruck Photon represents a formidable tool for the early detection of intruders on open sites, round the clock and in any weather. Unhindered by dazzling lights, darkness, mist or smoke, the Photon is ideal for spotting intruders from long distances. With the 19mm lens model intruders can be identified at up to 40 metres, humans recognised at up to about 80m and intrusion of some kind detected at up to about 310m. These ranges increase to 70m, 140m and 560m for the 35mm lens option and to 100m, 200m and 780m respectively for the 50mm lens version. Thermal imaging requires no illumination and is unobtrusive. It offers high detection probability even at long range because of the extreme difficulty for intruders to screen themselves against the technology.   The Argus pan and tilt unit itself is engineered to support extremely fast, precise camera work even in hostile environments. It accommodates a wide range of CCTV cameras with 12-240 mm zoom lenses including a range extender. It delivers a smooth, stable image - even for close-ups with a high power zoom - and pans at any speed from a slow crawl (0.01°/s) to a very fast sweep (200°/s). The 225 fixed positions for pan, tilt, focus and zoom are reached with extremely high accuracy (< +/- 0.01°), and the system automatically returns the head to its ‘home' position after any period of inactivity or following any attempt at unauthorised realignment.

Day/Night versions of Bosch DinionXF cameras on show at IFSEC
Day/Night versions of Bosch DinionXF cameras on show at IFSEC

At IFSEC 2005, Bosch Security Systems displayed two new Day/Night versions of its high-performance, 15-bit DSP DinionXF range.  For round-the-clock surveillance, the DinionXF Day/Night versions feature a built-in infrared filter for daylight surveillance that automatically moves from in front of the lens when the light level falls below a present value (at night infrared is the most useful region of the electromagnetic spectrum for imaging).  For night-time surveillance, the camera also automatically switches to monochrome mode to increase sensitivity. The DinionXF Day/Night versions have built-in, through-the-lens infrared metering and detection that prevent reversion to daylight mode if the camera is illuminated by an infrared source at night.  The IR filter can also be switched manually via the alarm input, through the camera menu or via the Bilinx coaxial bi-directional control interface.  The new cameras also feature SensUp that dramatically enhances the effective sensitivity by decoupling image accumulation from the video output and by increasing accumulation time on the CCD up to ten times.  Bosch’s SensUp works with continuous shutter speed adjustment for the smoothest possible video level control.  SensUp is most effective where the only light is from the moon, stars and scattered radiation. Enhanced night-time imaging guarantees round-the-clock surveillance Lens Wizard automatically detects lens type and sets focus for 24-hour cycle Video Motion Detection allows selection of four fully programmable areas XF-Dynamic feature extends dynamic range for outstanding image quality CCD imaging and DSP technologies enable best possible sensitivity
