Video Management

High quality digital and network recording facilities are a critical component of any successful CCTV strategy to ensure that potentially vital images are captured and retained safely for further analysis. While CCTV footage is popularly believed to play an important role in crime detection and prevention, in order for a system to be truly effective, robust recording equipment is a priority. Moreover, simply capturing and storing images indiscriminately does not, in itself, constitute an effective solution, Digital and Network Video Recording (DVR/NVR) technologies which merely capture and store footage fall desperately short of the levels of complexity required by most security and surveillance environments.

Autonomy Virage offers organizations state of the art DVR/NVR recording technology together with advanced retrieval functionality for rapid image recall to ensure that key images can be located quickly and easily for further analysis.

With storage capacity expanding into petabytes, the ability to record at full resolution across multiple channels and prioritize its activity dynamically, Autonomy Virage offers a new breed of DVR/NVR. Surveillance staff can link straight to live images from multiple cameras and locations linked to a DVR/NVR unit. All images captured and retained by the DVR/NVR resolve fine detail and allow users accessing images, either on the fly or in retrospect, to analyze detailed, high resolution images.

Unlike other systems which require extensive configuration by an administrator or are limited to one simple recording option, Autonomy Virage's solution is entirely flexible and can perform multiple recording functions simultaneously and reconfigure itself dynamically based on an alarm. Increasing the frame recording rate, switching between cameras or switching between storage buffer types, ensures resources are prioritized dynamically according to demand.

In general, the size of storage buffers will determine the length of time for which any images are retained, but where specific images need to be retained for an extended period of time, DVR/NVR provides multiple levels of archiving:

• Snap shot archiving: involves saving single images as a standard bitmap to the archive directory or CD - saved images may then be printed or emailed where it is necessary for other parties to gain access to the images.

• Streaming: enables users to review images from multiple cameras individually e.g. if an incident was suspected to have taken place between 3.00am and 3.15am an operator would be able to retrieve, store and review all the images from that time period individually using streaming.

• Major event download: used when large quantities of images must be retained for further analysis - using a local area network (LAN) connection and software provided by Autonomy Virage, images can be copied bit for bit onto another network computer with no impact on the current performance of the DVR/NVR system.
