Toshiba Launches Bullet Camera

Deploying megapixel cameras in outdoor video surveillance applications can be a real challenge. While video during the day is typically crystal clear, at night it may be blurry, dark or washed out, making it useless for retrospective analysis.
To combat this issue, Toshiba Surveillance & IP Video Group introduced its J-WB51A five-megapixel IP bullet camera. Built for outdoor deployment, it specifically is for 24/7 video surveillance with a powerful nighttime feature-set highlighted by adaptive IR LEDs, day/night IR cut filter, and True Wide Dynamic Range that ensures forensic-quality video, even in complete darkness or adverse weather. The adaptive IR LEDs have a range of up to 30 meters or approximately 100 feet, plus will automatically adjust the LED intensity to avoid over-exposure of close objects.
The J-WB51A’s 5MP CMOS sensor achieves image quality whether monitoring large outdoor areas or when zoomed-in. High frame rates of 30 fps at full resolution of 2560 x 1920 permits reliable capture of fast-moving objects, such as a car speeding or a suspect running. When combined, this speed and resolution delivers a superior level of detail that can make the difference when analyzing relevant information in the scene.
High resolution megapixel video presents serious limitations for network bandwidth and storage capabilities, especially when capturing moving objects. The J-WB51A leverages Smart Codec H.265 video compression to minimize video storage and bandwidth needs without sacrificing image quality by allocating bandwidth only to moving objects and not to the background. Multi-streaming in H.264, H.265 and motion-JPEG further optimizes the balance of video quality, storage, and networking requirements. In addition, users have the option of a 90° portrait view to only video stream narrow areas of interest such as a hallway, warehouse or retail aisle.
