Premier Electronics: W series Super Wide Dynamic Range cameras

Premier Electronics: W series Super Wide Dynamic Range cameras. The New W series Super Wide Dynamic Range cameras use multi-imaging sampling to render a clear image of both light and dark objects in the same scene.

These SWDR cameras are the first to apply double exposure technology in a security application and achieve a much wider dynamic range.

The camera first takes an image of the dark areas of the scene with a slow shutter speed which is stored in the first of two 16MB memories. Then the camera takes a higher shutter speed shot to acquire the bright areas of the picture and puts this in the second memory.

These two images are then processed and merged by the DSP to produce a correctly exposed picture. This process is then repeated 25/30 times a second to create a NTSC/PAL motion picture with a super wide dynamic image 280:1.

HVI Light Plus for Lightning Protection Applications

When installing bare, uninsulated air-termination conductors on the roof, the separation distance to electrical and metal systems installed under the roof surface must be maintained in accordance with the current lightning protection standard DIN EN 62305-3. Cable installations, pipe systems or metal parts are frequently installed under the roofing in direct proximity to the air-termination system / down conductor, thus posing a proximity issue. The solution is isolated air-termination systems with high-voltage-resistant, insulated down conductors.

DEHNventil ACI M: Standard-compliant Surge Protection in Industry

High demands are placed on the availability of switchgear in, for example, industrial plants, data centres, hospitals and large administrative buildings. This makes surge protection essential. At the same time, replacement of the surge protection module should not influence system availability. The new DEHNventil ACI M TNS 264 FM has no backup fuse and is flexible in terms of its application. In the event of a fault, the protection module is safely disconnected and can be quickly removed from the base part from either side or the front. The touch-safe design allows the protection module to be replaced without system downtime. The ACI technology employed also enables connection cross-sections of just 16 mm2. This facilitates installation and saves time.
