Case Study: Seagate Drives for Megapixel Video

Barracuda ES series used to match megapixel video recording from Avigilon


Challenges
• During product design, no commercially available hard disk drive (HDD) could provide the speed, reliability and capacity required.
• When current conventional surveillance systems go into alarm mode and multiple cameras begin recording at the same time, the frame rate must be slowed and image quality reduced, to ensure all data can be captured and stored, resulting in low-quality video.

Solution • Seagate's Barracuda ES Series, the industry's highest capacity enterprise SATA HDD, provides up to 750GB of storage.
• The Barracuda ES Series is designed for the speed, capacity and reliability required for recording intensive 24x7 enterprise video surveillance.
• The Barracuda ES Series offer extremely smooth playback.

Benefits • Seagate's surveillance market leadership is exemplified by offering the industry's widest portfolio of hard drive products for video surveillance exhibiting an unparalleled level of focus and dedication to the specific needs of video surveillance solution manufacturers.
• The Barracuda ES off-the-shelf drives are plug-and-play, providing an immediately stable and reliable platform that helped accelerate Avigilon's time to market.
• With the Barracuda ES, a single 16 megapixel Avigilon camera can take the place of 50 conventional surveillance cameras.
• The Barracuda ES's redundant array of independent disks (RAID) features enable multiple 16 megapixel IP cameras to record at full frame rate at the same time.
• The combination of Avigilon's multi-megapixel IP cameras, their high definition network video recorders and the Barracuda ES Series dramatically decreases the amount of equipment required for a surveillance project, reducing installation and maintenance costs.
• Because high-capacity Seagate HDDs have the performance to capture and store the entire high-resolution video stream, Avigilon's 16 megapixel cameras are able to provide a superior solution for post incident investigation by providing detailed images of the entire field of view, without the costs associated with having an operator to control the camera.

The State of the Art that Wasn't

In the face of rising terror threats, extensive street-by-street video surveillance is becoming a priority in densely populated cities. As the August 2007 Minneapolis bridge collapse revealed, video surveillance can be critical to understanding any unexpected event. However, poor quality imagery limits the effectiveness of surveillance video identification and detail. Too often, video is blurred and grainy due to low-resolution cameras that use lossy compression, or choppy because it was not recorded at its full frame rate.

When Avigilon set out to design its next-generation surveillance system, the team of technical experts (who have worked together in digital imaging for more than 15 years) was committed to creating a high-quality system that would satisfy the needs of the most demanding security professionals and the most complex surveillance projects.

The Avigilon team recognized that existing technology simply was not up to the task. The first problem was poorly recorded images. Conventional surveillance systems use multiple low-resolution cameras and lossy compression to monitor events. When an incident occurs, all cameras go into alarm mode and start recording at the same time. However, due to very limited storage capabilities of conventional surveillance systems, the frame rate and image quality must be reduced at the most critical times, resulting in poor image quality being captured exactly when high image quality is needed.
