Frequently asked questions
What does a video wall controller do?
A video wall controller takes video streams from sources such as NVRs and IP cameras and lays them out across the wall's displays. The Veracity VSPAN-PLUS-12-UK decodes and displays 108 Full HD streams at 30 fps through twelve mini DisplayPort outputs, with embedded VIEWSPAN Nexus software. The Hikvision DS-C30S-DEC decoding board and DS-C30S-02HI/4K input board fit a Hikvision video wall controller.
How does a video wall show one picture across several screens?
A video wall controller drives the screens of a video wall as a single display canvas, so one picture can run across the wall. The Veracity VSPAN-PLUS-12-UK has twelve mini DisplayPort outputs for HD or 4K monitors. On the display side, the Hikvision DS-D2055LR-G has DVI, VGA, HDMI and DP video inputs and can auto loop up to 30 screens through its HDMI interfaces.
Can a video wall show a 4K signal?
Yes, a video wall can show a 4K signal when its controller inputs and displays accept 4K. The Hikvision DS-D2055LR-G display takes a 4K signal input, and each output of the Veracity VSPAN-PLUS-12-UK can drive Full HD or UHD monitors at full resolution. The Hikvision DS-C30S-02HI/4K is a 4K HDMI 2-channel input board for a video wall controller.
Can a video wall controller show CCTV cameras?
Yes, a video wall controller can decode streams from CCTV recorders and IP cameras and show them on the wall. The Veracity VSPAN-PLUS-12-UK is designed for CCTV and video wall display applications, decoding 108 Full HD streams at 30 fps with fisheye camera de-warping. The Hikvision DS-C30S-DEC decoding board decodes up to 16 channels of 1080p@30 fps or 4 channels of 8 MP.
How narrow can the bezel between video wall displays be?
Narrow-bezel video wall displays can bring the bezel between neighbouring screens below 1 mm. The Hikvision DS-D2055LR-G LCD display has an extreme-narrow 0.88mm bezel between neighbouring displays, with direct-lit LED backlighting at 500 cd/m2 and no boundary shadows. The Hanwha Vision LH55VHCEBGBXEN is a 55" bezel videowall display.
