| 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
