between devices throughGigabit switch networking, network stacking, not limited by the chassis, unlimited expansionSingle wall maximum support 256 screen 1080P splicing4K mode maximum support 4096 screen; each input/output nodeIndependent power supply, independent work, single-node failure does not affect the entire system, the server supports multi-machine disaster recovery backup, fault automatic mutual cutting, to ensure 7 × 24 hours of uninterrupted duty.
Control Software Support Windows / Android / IOS / 鸿蒙Multiple terminals, support CS Client Web PageDual control terminals; compatible ONVIF / RTSP The protocol can be directly connected to Haikang, Dahua, Yushi network cameras and NVR code streams on the wall, and SDK is provided to support secondary docking of third-party platforms.
The inherent limitations of centralized matrix in 7 × 24 scenarios such as command center and security monitoring are exactly the problems to be solved by KW-4100 distributed architecture.
The whole machine chassis fails and the whole large screen system is paralyzed. The port is fixed, the whole machine must be replaced for expansion, and the transformation cost is high.
KW-4100 scheme:The nodes work independently with independent power supply, and the failure of a single node does not affect the system; the network is stacked and expanded without changing the chassis.
The output frames of multiple splicing screens are not synchronized, the images are torn and misplaced, and the command and monitoring scene seriously affects the business research and judgment.
KW-4100 scheme:Frame synchronization technology, multi-screen synchronization <20ms, eliminate tearing dislocation.
Can not directly access the network camera, NVR stream; can only be connected to the local HDMI signal, long-distance wiring costs are high.
KW-4100 scheme:ONVIF / RTSP direct network camera, NVR stream on the wall, IP network long-distance transmission.
No signal preview echo, switch signal blind operation, debugging trouble, emergency scene delay time.
KW-4100 scheme:Client large screen real-time echo, signal pre-monitor, drag the window track synchronous echo.
OSD subtitles, high-definition super-large base map, pre-plan round trip, and third-party IoT device linkage control are not supported.
KW-4100 scheme:OSD subtitles, 30720 × 17280 basogram, 256 group plan, and central control IOT linkage are fully supported.
Can only be operated by computer, does not support tablet, mobile phone multi-terminal collaborative control.
KW-4100 scheme:Windows / Android/IOS/Hongmeng, CS Web dual-ended, multi-touch collaboration.
It is difficult to adapt the protocols of security equipment such as Haikang, Dahua and Yushi. Without SDK, third-party platforms cannot be docked.
KW-4100 scheme:Compatible with Haikang/Dahua/Yushi private agreement, SDK is provided for third-party secondary development.
Insufficient wide temperature work, poor stability of equipment in the computer room and field environment; lack of multi-machine disaster recovery backup.
KW-4100 scheme:-30 ℃ ~ 50 ℃ wide temperature work, Linux server multi-machine disaster tolerance, fault automatic mutual cutting.
The following parameters are from the technical specifications of KW-4100 series products and can be directly used for reference in bidding documents and acceptance documents.
There is no operating system pure hardware architecture, each input/output node is powered on and works independently, and does not rely on the backplane and the main control chassis; the failure of a single node does not affect the operation of the rest of the entire system. The equipment is networked through a gigabit switch, without physical connection lines, and is not limited by the slot of the chassis, with unlimited expansion in theory. The server deploys a Linux system to support multi-machine disaster recovery backup and automatic fault switching, ensuring 7 × 24 hours of uninterrupted duty.
The H.265 coding bandwidth is low, the end-to-end delay is less than 0.1s, and the maximum delay of signal acquisition is less than 0.2ms. Frame synchronization technology ensures that the synchronization of multi-screen images is less than 20ms, eliminates tearing and dislocation of spliced screen images, and is suitable for various display units of LCD, LED and DLP. All output channels are processed in real time at 60Hz, internal frames are not reduced, RGB 32bit / 60Hz high color reproduction is supported, and point-to-point display is supported. Single output node has a maximum of 16 channels of H.265 decoding, supports H.264 / H.265 hybrid decoding, is compatible with ONVIF and RTSP protocols, and can directly access Haikang, Dahua, Yushi network cameras and NVR code streams on the wall.
