A fully featured four channel blade type video surveillance encoder, utilising state of the art image transmission and enhancement technology
Sony’s unique XDNR (Excellent Dynamic Noise Reduction) and VE (Visibility Enhancer) and DFI (Dynamic Frame Integration) Technology come as standard features within the SNT-EX series of encoders. This unique image enhancing technology delivers superior noise free images in the most challenging conditions. By utilizing Sony’s SNT-EX series with XDNR, VE and DFI technology high quality D1 resolution support, analogue camera’s can now deliver superior imaging performance
The SNT-EX series supports three compression formats: JPEG, the best choice of high-quality still images; MPEG-4, the format that provides clear moving images efficiently over limited-bandwidth networks; and H.264, the alternative for severely limited-bandwidth networks, providing twice the efficiency of MPEG-4. The encoder can transmit up to two different format video streams simultaneously.
XDNR (Excellent Dynamic Noise Reduction) technology virtually eliminates image blur in low-light conditions, enabling users to clearly capture images that have not been easy to portray in the past. It also overcomes the problems associated with many competitor camera models. What's more, when both XDNR and Visibility Enhancer are turned on, the cameras can achieve four times the sensitivity compared to when they are off. This technology is ideal for any outdoor surveillance monitoring, such as in a car park at night.
VE (Visibility Enhancer) technology improves performance in challenging lighting conditions, for example high-contrast environments, such as casinos and highways, that had previously been difficult to monitor. The Visibility Enhancer’s advanced system suppresses extreme whites and boosts dark areas in a scene simultaneously and dynamically, to produce clearer images on the screen.
DFI (Dynamic Frame Integration) technology produces superior images from scenes containing both still and moving objects. DFI technology detects moving objects and reduces motion blur, simultaneously detecting stationary objects and reducing jagged edges. DFI delivers an optimized image with superior clarity and can be added to any analogue system by utilizing Sony’s SNT-EX series.
Sony’s SNT-EX Series encoder’s include a complete IP surveillance solution based on its Distributed Enhanced Processing Architecture (DEPA™) platform. Intelligent video analytics automatically identify critical events for a high-level of security and to provide streamlined workflows. Unlike conventional monitoring solutions, the DEPA solution provides added intelligence to assist the surveillance operator in taking quick action. Users can precisely refine parameters for use in conjunction with the Intelligent Motion Detection and Intelligent Object Detection functions. By utilizing the SNT-EX series encoders, analogue cameras can now deliver the significant benefits offered by DEPA Advanced analytics
The Sony SNT-EX154 encoders are complimented by a range of blade mounting accessories. Comprising of 1U and 3U rack options the encoding system can be expanded by adding SNT-EX154 blades to accommodate up to 16 or 48 analogue channels respectively
When an attempt is made to tamper with the camera, such as spray-painting the lens, the SNT-EX Series detects this and triggers an alarm. This event can also be used to activate the camera relays, or even to start the Voice Alert function.
Unlike conventional audio detection where an alarm is triggered based on a preset audio level, the SNT-EX Series triggers its alarms based on ambient sound conditions as the threshold. The camera stores and updates ambient audio levels and frequencies, and when the threshold level based on this data, is surpassed, an alarm is triggered.
The encoder can store up to three pre-recorded audio alert messages which may be played via an active speaker upon manual or automatic initiation
The SNT-EX series offers support for control of 3rd party telemetry cameras. Maximum flexibility of control is offered via RS-422, RS-485 and Coaxitron interfaces
Video can be stored on optional USB memory media and then streamed using RTP/RTCP or RTSP protocols. This function is available with s/w version 1.1 or later.
External storage is also possible using USB flash memory. Continuous, pre and post event video may stored in compressed format for later retrieval.
The SNT-EX Series supports Internet Protocol Version 6 (IPv6).
The ONVIF (Open Network Video Interface Forum) defines a common protocol for the exchange of information between network video devices including automatic device discovery, video streaming and intelligence metadata. Allows interoperability between network video devices. By utilizing Sony SNT-EX encoders, analogue systems can fully benefit from full ONVIF interoperability.
