Supports double clicking the divided sub-window to zoom in and double clicking again to zoom out.
Supports displaying output channel number.
Supports PTZ control of network signal sources, including 8-direction control, auto-scanning, aperture adjustment, focal length change, focusing, and preset calling.
Supports setting the live view status, decoding status, switching status, audio status, and location of the signal source window.
Supports video recording playback. You can set the playback status and select time to play back.
Supports using the HCP client to capture images on the screen and display the captured images on the video wall.
Supports the live view of network signal sources over RTP or RTSP.
Device Access
Supports docking with 32 MP PanoVu series cameras, fisheye cameras, conventional front-end network cameras, DVRs, NVRs, XVRs, and mainstream third-party security devices.
Supports integrating multiple decoding devices into one decoding device on the platform by using the software development kit (SDK).
Supports using the ONVIF protocol to access the decoder.
Supports interaction with LCD screen, including the screen information acquisition, image mode configuration, serial port control, time synchronization, backlight parameters configuration and acquisition, output port auto-binding, and error code reporting.
Supports IPv4 and IPv6 protocols and the simultaneous access of IPv4 network sources and IPv6 network sources.
Supports using the network keyboard or serial port keyboard to control the device, and to realize sub-window changing, group operation and auto-switching, scene changing, PTZ control, and video wall playback.
Maintanence
Supports using the PC client and web browser of Chrome 45 and higher version to access and control the device.
Provides built-in Gigabit switching network, and supports auto-adaption between the optical port and electrical port, and supports NAT.
Supports obtaining and configuring parameters remotely, importing and exporting parameters remotely, and obtaining system running status and system logs remotely.
Supports restarting the device remotely, restoring the default settings, and upgrading the device.
Supports auto detection and alarm for failures, including network disconnection, IP conflict, illegal access, temperature threshold exceeding, decoding signal source exception and device exception.
Supports user permission management, allowing users with different permissions to use designated resources and operate designated video wall modules.
Supports visualization maintenance. The maintenance interface displays the network topology structure and keynote network status of main control system and subsystems.
Supports manual time synchronization and NTP time synchronization.
