Tsunami Quad is unique amongst wavelet cards in offering full resolution AND full frame rate capture and compression simultaneously on all 4 channels. This is achieved by providing a dedicated video decoder and compressor for each input. In fact, the card appears to the user exactly like 4 separate Tsunami Single cards.

Although video may be replayed by software decode and rendering to a VGA screen, this requires a powerful CPU to approach realtime performance. For best results a Tsunami Single card should be used for replay to CCTV format.

Due to the wide variety of user requirements for special facilities (video connectors, alarm and trigger I/O etc) Tsunami 4 has only basic facilities on-board. Access is provided to all necessary points via standard headers to allow production of simple plugin adaptors as required. A range of typical accessory boards are under development, driven by customer demand.
