Bullet style megapixel cameras

by Mark Rowe

Arecont Vision, the US maker of IP megapixel cameras, has added features to the company’s MegaView 2 day/night bullet style megapixel cameras.

New features of the MegaView 2 IP bullet camera being debuted at Intersec 2015 include Arecont Vision’s STELLAR (Spatio TEmporal Low Light ARchitecture) technology, optional on-board storage; CorridorView; and non-integer scaling.

The MegaView 2 has STELLAR to reduce motion blur, noise and storage requirements. That enhances contrast and produces colour imaging in near complete darkness on 1.2MP models, the makers say. Due to its ability to capture object details in extreme lighting, this camera is suitable the makers say for many low light applications.

To reduce the risk of losing important data from short network outages or to help reduce network strain from high storage costs, the camera includes local storage supporting up to a 32 SD/SDHC card. The CorridorView feature allows the camera’s image to be rotated 90 degrees to reduce capturing unnecessary data. This works for narrow hallways where pixels are often wasted due to capturing the surrounding walls, the company says.

As for bandwidth and storage costs the camera features non-integer scaling which provides the ability to scale images to different resolutions down to 128×96. This allows users to tailor their system; reducing system bandwidth and storage costs.

The bullet cameras feature the firm’s true wide dynamic range (WDR) technology which provides a dynamic range of up to 100dB at full resolution without the company adds lowering frame rates (1080p and 3MP models). By combining long and short exposures in the same field of view, WDR maximises the amount of detail in both bright and dark areas of a scene. The WDR of Arecont Vision cameras represents up to 50dB improvement (300X) in dynamic range compared to conventional megapixel cameras, it’s claimed.

Raul Calderon, Senior Vice President, Arecont Vision, said: “Arecont Vision continues to establish new benchmarks in megapixel performance to address the evolving needs of our customers,” said . “As we continue to innovate new megapixel imaging products, we will also continue to improve upon existing market leading products such as our MegaView 2 Day/Night megapixel cameras by adding enhanced features such as STELLAR that further improve their performance and coverage capabilities.”

Also featured in MegaView 2 cameras: remote focus/zoom p-iris lenses, integrated infrared illuminators, wide angle or telephoto options; H.264 (MPEG-4 Part 10)/MJPEG dual encoders; privacy masking; extended motion detection with 1,024 distinct motion detection zones; pixel binning for increased light sensitivity (3MP, 5MP and 10MP models); IP66 environmentally rated housings for use in harsh sites; flexible cropping to adjust image sizes; and the ability to choose PoE (Power over Ethernet) or external power. MegaView 2 Telephoto cameras are available with integrated long distance infrared illuminators in resolutions of 1080p, 3MP, 5MP and 10MP.

The new cameras work with third-party providers, as they are PSIA and ONVIF conformant. Harco Group, Norbain, and Systematrix/PXLines are displaying Arecont Vision cameras in their booths at Intersec. VMS partners Aimetis, AxxonSoft, Genetec, and Milestone Systems will also feature Arecont Vision cameras at the event. Visit www.ArecontVision.com.
