Smart Pole IP Network Speaker Column, Waterproof IP Network Speaker Column for Smart Pole

Smart Street Light IP Network Speaker Column, Waterproof IP Network Speaker Column for Smart Pole, Compatible with Linux OS Integration

The platform supports public cloud/private cloud, local area networks, wide area networks, and is capable of crossing routers and the Internet. It can be used anywhere TCP/IP networks are accessible.
★ Supports cross-platform applications on Windows 2008/2012/Win7/Win10/Linux/Chinese Kirin system, etc.; ◆ A single regional server supports up to 5,000 terminals online simultaneously, and can stream different programs to over 3,000 terminals concurrently;
★ Employing unicast/multicast auto-switching technology, it can automatically find the optimal transmission method, cross any router and internet network without any conversion, without modifying the enterprise's core network settings, ensuring transmission efficiency and stability.
★ Control commands use TCP transmission to ensure reliable data reception without packet loss. Audio and video streams use UDP transmission to ensure real-time data delivery, with audio delay less than 50ms and video delay less than 80ms; ★ Network packet loss rate less than 5% allows normal operation, less than 20% allows voice recognition, and automatically handles packet loss, duplicate packets, out-of-order packets, and other network transmission issues (while other manufacturers' products have limited fault tolerance in complex network environments, network packet loss rate above 5% results in lag, silence, and inoperability).
★ Media servers and streaming servers are infinitely scalable, with endpoints automatically seeking the nearest media and streaming servers for rapid response, achieving load balancing and redundancy. In large-scale applications requiring cross-INTERNET connectivity, this can save significant bandwidth, enhance real-time performance, and improve stability.
★ Paging and broadcast support multiple audio formats, up to CD quality.
★ Low bandwidth requirement; operates in environments as low as 20kbps; ensures clear voice in 50kbps; achieves good audio-video quality in local networks; occupies minimal bandwidth on the INTERNET; restores more realistic original sound; multiple real-time audio-video technologies ensure real-time transmission in weak network conditions.
◆ Supports third-party platform embedded development: Provides SDK for secondary development and integration with other system platforms. Third-party software can directly control terminal intercom and broadcasting, and receive the current status of the terminal;配合monitoring system, the system can be controlled by the monitoring system for power on/off, or automatically switch monitoring screens during calls; Achieves integration with large systems and platforms;  ★ Synchronization, playback error between terminals <50ms;
★ The platform supports simultaneous logins for multiple users. Different-level users manage and operate within their authorized terminal jurisdictions based on their permissions.
Support remote upgrades for systems and terminals, featuring a log trace mechanism for full OTA upgrades at both software and hardware ends, ensuring zero omissions in device upgrades and easing the workload of maintenance staff.
Each device comes with a QR code containing its identity information. By scanning it with a mobile app, you can directly modify the terminal device name and other settings on-site (there's no need to bring the device back to the server room for individual configuration, thereby shortening the device debugging cycle).
★ The platform supports offline backup functionality, featuring a built-in 2G EMMC memory and 256M DDR flash storage. The system automatically downloads scheduled points to the terminal memory during network downtime. Programs are streamed and stored simultaneously, with the system using a comprehensive algorithm to ensure there's enough space in memory based on playback frequency and the next scheduled program. Normal playback of scheduled points is maintained even without network access, and once the memory is saved, subsequent plays will not consume data traffic.
★ The platform supports playback of various formats including MP3/MP4/MKV/FLAC/WAV (plays original files with CD-quality sound).
★ Supports mobile APP on-demand, paging to any terminal, intercom, quick operation, map location, modify terminal attributes.
Live Broadcast: Available through IP broadcast console, local simulated microphone, phone, tablet, and mobile app for live streaming.
★ Supports third-party desktop audio capture and broadcasting;
★ Supports internet radio, with a vast library of audio programs available for playback.
Supports text-to-speech broadcasting functionality.
The platform supports terminal environment sound.
Regulation: Capable of monitoring ongoing tasks within the current system. If illegal content is detected during the process, it can be immediately locked on the secondary management platform. The terminal can only broadcast local programs after the lock is released by the platform, without affecting the broadcast of program information issued by the superior platform.
Supports an overview of cloud broadcasting big data analysis, displaying all terminal counts, online status, terminal operating temperatures, map display of terminal locations, real-time working status, volume, task broadcasting status, and various types of task states within the system. It can be used for large screen displays, providing a clear view of system operations.
◆ Video Command and联动: Compatible with Hikvision, Dahua third-party cameras, integrated with video platforms, controlling broadcast terminals via camera signals for remote broadcasting and intercom;
Supports remote on-demand server media library function, remote paging microphones can play media library programs from the entire area, a specific zone, or any terminal.
★ User-level setting management function and priority level setting are available, designed with the logic that the higher the administrative level, the higher the priority. Daily broadcasts prioritize higher-level superiors, while emergency broadcasts prioritize lower-level subordinates. The platform supports personalized level settings.
The platform supports the function to set the priority of audio sources, allowing priority settings for various audio sources.
The platform supports real-time broadcast of audio, video files, and the editing and publishing of图文 across the entire region, sub-regions, and individual points.
The platform supports remote settings for functions such as volume and logical address for terminals.

◆ The platform supports fire alarm interlock function, allowing pre-setting of emergency broadcast audio sources and areas according to actual emergency needs. When broadcast commands are issued (such as pressing a physical button, connecting a triggering signal, etc.), corresponding terminal broadcasts are triggered in联动 alarms.
The platform supports the storage of login time, IP address, logout time, phone number, SMS, and published content, and allows for inquiries on the aforementioned information.
★ The platform edits a series of complex operations into quick actions, automatically generating buttons on both PC and mobile devices, with no limit to the number of shortcut keys.
★ The platform supports online and offline notifications for terminal updates.
◆ The platform supports the simultaneous activation of multiple scheduling plans, each plan allowing multiple tasks to run concurrently, and enables individual enablement/disabling of any plan for unattended operation.
The platform supports importing audio sources from the local server media library via remote methods; it also supports real-time analog input, converting analog sources into digital in real-time, enabling any number of real-time capture and broadcasting.
◆ The platform supports converting traditional audio resources into digital programs for storage in the system server's program library, allowing users to access them freely and play them continuously without repetition.
◆ Seamless integration with IP network equipment and 4G wireless devices.
