Surveillance lens overcomes weather interference

Pentax Imaging : 07 December, 2009  (New Product)
Pentax Atmospheric Interference Reduction technology enables outdoor surveillance camera systems to operate without detrimental effect from fog, snow or other weather conditions
Pentax Imaging has announced new technology to overcome the big challenges of the atmospheric interference of fog, snow, and haze in outdoor live security surveillance. Pentax Atmospheric Interference Reduction (PAIR) system technology offers newly developed image processing circuitry installed directly within Pentax lens housings with specific step-by-step signal processing for each lens characteristic.

The primary advantages of in-camera PAIR technology include:

* No image adjustment requirements.
* Real-time clear images available immediately after video switching with multiple cameras.
* Removable noise (graininess) that is caused by solid particles such as snow, smoke, or sand or by liquid particles such as fog and rain.
* Colour image reproduction for more accurate information.
* Half the cost of dedicated devices such as image enhancers and/or element cancellation devices.
* Autofocus.

"PAIR technology entirely eliminates the need for more expensive, separate fog cancellation devices that require multiple cameras with individual adjustments," said Tom Harada, Managing Director of Security Systems and Machine Vision Optics, Pentax Imaging Company.

Pentax PAIR zoom lens models featuring new technology:

* H55ZAME-F-PAIR01 1/2 INCH 55X Zoom Lens f=12mm~660mm (~1680mm with 2.5x Extender) F4.0~360 (*model most suitable for border/harbour patrol surveillance)

* H33ZME-F-PAIR01 1/2 INCH 33X Zoom Lens f=10~330mm F1.5~560

* H20ZAME-F-PAIR01 1/2 INCH 20X Zoom Lens f=12~240mm F1.6~720
