    Sony of Canada Ltd., Canada's leading supplier of
    electronic and computer products for consumers and business, today introduced
    the SNC-RZ25N, a pan-tilt-zoom camera that enables remote viewing and
    high-quality video capture over existing IP (Internet Protocol) networks
    through MPEG-4 compression in addition to JPEG modes.
    Offering highly sensitive IP monitoring capabilities on smaller bandwidth
    and equipped with a built-in web server, the Sony SNC-RZ25N camera's
    capabilities maximize bandwidth resources to create an effective and
    economical platform for IP surveillance systems to operate on a broad base of
    existing academic, corporate, and institutional networks.
    Employing the latest 1/4 type Exwave HAD(R) technology, the SNC-RZ25N
    camera delivers exceptional picture quality, even in low-light conditions.
    Additionally, the camera includes audio monitoring via a built-in microphone
    as well as an external microphone jack, active speaker output, and a new
    "Day/Night" function, which provides optimized sensitivity in both daylight
    and dark environments. During normal/daylight hours, the camera provides image
    output in colour. As the surveillance scene darkens, the infrared cut-filter
    is automatically replaced with a clear filter and switches to black-and-white.
    The switches can be set through manual, automatic or timer settings.
    "The SNC-RZ25N camera marks a new generation in network cameras that
    delivers advanced features and functionality with the exceptional efficiency
    that MPEG-4 affords," said Carlos Varela, Product Manager, Surveillance
    Products, Broadcast Communication Solutions Group, Sony of Canada Ltd. "It
    provides an exceptional value proposition for both those who have been
    considering when to make the shift from legacy closed circuit to IP-based
    security systems, as well as for those interested in an initial installation."
    Mr. Varela said that the reduced bandwidth requirements of the SNC-RZ25N
    camera makes IP-based security possible and practical for a much wider market.
    As such, it leverages additional returns on existing IP infrastructure
    investments made by academic, corporate and private institutions.
    "IP video surveillance is a value-add that realizes the promise of IP
    communications," said Mr. Varela. "Our MPEG-4 camera makes this application
    feasible to many more IT managers and is an eye-opener for those who think
    they are already getting the most from their bandwidth with just e-mail and
    Internet access."
    The SNC-RZ25N camera produces high-quality MPEG-4 images with 640 X 480
    pixels maximum resolution at up to 18 frames per second (fps), and up to
    30 fps at 320 X 240 pixels resolution. Images can also be compressed into JPEG
    motion or still files. The camera also features a CCD, SteadyShot(R)
    functionality and an integral 18x auto-focus zoom lens.
    The camera provides support for various networking protocols, including
    TCP/IP, DHCP, FTP (File Transfer Protocol), SNMP (Simple Network Management
    Protocol), SMTP (Simple Messaging Transport Protocol) and an RS-232C port. It
    also has a compact flash slot for wireless networking or for the storage of
    additional images.
    Network features include Adaptive Rate Control to control Quality of
    Service (QoS) over IP. This function automatically varies the audio and bit
    rate transfer rate to meet changing network conditions, and selects the most
    appropriate frame rates, helping to prevent audio and video breakup. Also
    included are Simultaneous Access, which allows up to 20 (JPEG mode) and 10
    (MPEG-4 mode) users to simultaneously access the camera, and a multicasting
    capability, which, when configured with a multicasting router, can efficiently
    stream video and audio to numerous users.
    A built-in motion detector enables the camera to sense alarm events and
    can be programmed to trigger alerts. The camera can attach and send the image
    captured during the alarm as an email to a specified address. Additionally,
    the SNC-RZ25N camera provides an analog video output.
    The SNC-RZ25N camera is part of Sony's comprehensive line of
    IP-addressable network cameras and takes its place alongside the highly
    successful JPEG-only SNC-RZ30N camera. In addition to serving as integral
    elements of a tightly integrated Sony IP Surveillance system, both cameras
    incorporate open industry standards for interoperability with third-party
    hardware and software.
    Sony's SNC-RZ25N network video camera is planned to be available in
    December at a manufacturers suggested retail price of $1,668.
