Basler launches two CMOS sensor IP cameras

It follows the launch of its charge coupled device (CCD) box camera models last December.

The CMOS cameras have 720p HD and 5 megapixel resolutions, and a third model with 1080p full HD resolution is due to follow next month.

Its BIP2-1280c-dn high definition model has been designed to provide real-time video at a frame rate of up to 30 fps using Mjpeg, Mpeg-4, and H.264 compression. It has also been equipped with a five megapixel sensor designed to be able to record image details at a frame rate of nine fps.

“CMOS sensors exhibit a number of image quality related advantages such as the almost complete lack of smearing effects, i.e., stripes in the image caused by an extremely bright light source,” a spokesman said.

Blooming is rare

“Blooming, a condition where very bright image structures extend into the darker structures, is also a very rare effect in cameras equipped with CMOS sensors as compared to CCD sensor cameras.”

The cameras support multi-streaming and multi-encoding and have been made to provide up to four image streams using ‘any encoder type combination’. The user should be able to encode up to four streams using the same encoder type, such as H.264.

“Before our IP cameras enter series production, we perform careful quality tests to make sure that the cameras are best suited for surveillance tasks,” Gerrit Schreiber, product manager IP components, at Basler, said.

“And now that the cameras have entered series production, we have implemented a number of additional tests to ensure consistent quality and avoid camera failures.”
