PCI Express card provides multi-channel digital video recording

September 22, 2015 // By Graham Prophet
For surveillance installations, that need high resolution digital video recording, Exar offers a complete plug-in card solution, the VRC7008E DVR PCIe card, that records 8-channel 960H video with H.264 encoding at full-frame rate and resolution

Designed for professional video surveillance applications, the VRC7008E card hosts Exar’s S7100 software configurable processor and performs H.264 encoding on eight channels of up to 960H NTSC/PAL video at full resolution and frame rate. With 960H video, surveillance professionals get 33% greater horizontal field-of-view (FOV) than that provided by typical CCTV video cameras, reducing the number of surveillance cameras required and increasing resolution for a given coverage area.

Extensive video preprocessing coupled with Exar’s Intelligent Encoder gives the VRC7008E video quality while maintaining high compression levels. This results in significant reduction in storage costs for surveillance installations using the VRC7008E card. The programmable accelerator of the S7100 at the core of the intelligent encoder delivers multi-stream encoding of baseline, main and high-profile H.264 Advanced Video CODEC (AVC). The S7100 video processor drives H.264 Scalable Video CODEC (SVC) compression, enabling flexible and efficient resizing and resampling of multi-stream surveillance video. Compressed video can be adapted to match the available network bandwidth and decode capabilities of the client. SVC streams also can be parsed to reduce their storage requirements over time to retain a valid video archive for longer periods than would otherwise be possible. T

The low profile, short form factor card is intended for embedded use in compact industrial PCs and servers. A high bandwidth PCIe interface provides connectivity to the host. The card also supports eight channels of alarm I/O and an RS485 interface for remote camera control through an I/O header with an optional I/O card.
