New levels of intelligence added to Sony recorders

To simplify and enhance every aspect of video surveillance, Sony has recently extended new levels of intelligence to its NSR Series of network surveillance recorders.

Sony NSR-25, NSR-50 and NSR-100 network surveillance recorders now include version 4 software, extending the capabilities of this dedicated hardware and optimising the capabilities of all the intelligent components of a Sony surveillance network.

With version 4 software, these recorders have acquired a more intelligent and efficient method of processing data, based on the Sony distributed processing architecture (DEPA) platform. These recorders can now use metadata and filters received from DEPA-enabled cameras to analyse object movement. This method of distributed processing also drastically reduces server workload, network bandwidth and storage capacity requirements.

Cameras can be instructed to trigger an alarm only when a particular object movement or situation occurs, and this can be refined by specifying the size, direction and speed of the object. When the recorder receives the alarm signal from a camera, an intelligent motion detection (IMD) function triggers the required alarm or performs other required actions, such as locking a door or turning on lights.

Another example of intelligent synergy is the new Intelligent Video Motion Filter Search function, which drastically reduces image retrieval and review times. The upgraded NSR Series recorders are able to search the exact same filters (or rules) that are applied to monitoring with the DEPA-enabled cameras.

The recorders automatically recognise and register any installed network cameras and assign IP addresses to them. After this, the recorder generates an appropriate monitoring layout based on the number of registered cameras.

The intuitive graphical user interface (GUI) is extremely easy to use and lets users set up viewer windows in various combinations.

The upgraded NSR Series recorders also support multiple hot-spot monitoring. This means a user can designate one window in a multicamera view to be a 'hot spot' to ensure that crucial events within this area are not missed. In a dual-monitor configuration, up to four hot-spot monitor windows can be assigned to the second monitor.

Other features include remote control, support for both MEPG-4 and JPEG, flexible recording modes, VCL protocol integration, and NTP and FTP support.
