on GV-Video Wall

Article ID: V2-14-06-24-c Release Date: 06/24/2014

Applied to

GV-Control Center / GV-Video Wall V3.1.2.0.

Summary

This technical notice examines the performance data of a GV-Video Wall where IP channels from GV-NVR and GV-Recording Server are displayed using various features. Up to 9, 1920 x 1080 monitors are used.

All the data were obtained using Core i7 with GPU decoding which allows for more channels to be displayed on GV-Video Wall. Note that at least one monitor needs to be connected to the on-board VGA on the GV-Video Wall server for GPU decoding to function. For more detailed specifications, refer to 4. GPU Decoding Specifications in this document.

1. Results

1.1 Maximum number of channels and maximum number of full-frame channels

On 8 monitors each with 1920 x 1080 resolution and 6 x 6 divisions, GV-Video Wall can display up to 288 IP channels (of 320 x 180 resolution each) from GV-NVR in CIF (30 fps) and VGA (20 fps), as illustrated below.

For channels of other resolutions connected from GV-NVR and channels of all resolutions connected from GV-Recording Server, GV-Video Wall can only display up to 288 channels by lowering the frame rate. The test results are summarized below.

• CIF: Video Wall supports up to 288 channels (fps = 30) from NVR or up to 288 channels (fps = 10) from Recording Server

• VGA: Video Wall supports up to 288 channels (fps = 20) from NVR or up to 288 channels (fps = 5) from Recording Server

• 1.3 MP: Video Wall supports up to 288 channels from NVR or Recording Server (fps = 1)

• 2 MP: Video Wall supports up to 288 channels from NVR or Recording Server (fps = 1)

Note:

1. If the live view placed across two monitors is not smooth, disenable the DirectDraw function for the GV-Video Wall.

2. This performance test does not apply to Media Windows and Web Windows which are not used to display IP channels.

2. Conclusion

Based on the performance data and the test environment, GV-Video Wall can achieve the independent features described in sections 1.1 to 1.9. You may also use a combination of these features on a video wall. However, the maximum number of channels/windows you can establish on a video wall varies depending on the CPU capacity. For optimal performance of video wall, keep the CPU usage under 70-80% to reduce image delay or drop-frame issue.
