25W POE coaxial ceiling speaker,DC24V@30W IPC-525POE

Product Spec:
1. Integrated high-fidelity design, using a 5" mid-bass speaker unit and a 1.5" dome tweeter unit, with a plastic rear shell box, using a 2-way frequency design, perfectly restoring human voice and music, and easy to install fast;
2. It can be used directly by connecting to the network. Each speaker can be used as an independent partition, suitable for ordinary classrooms, multimedia classrooms, offices, conference rooms, prisons, hospital departments, subways and other places;
3. Support DC power supply and POE power supply (support POE general international standard IEEE 802.3at (25.5W) protocol, only need a network cable to connect to the switch);
Features:
1. Adopt liunx system; high-end 4-core ARM chip, stable performance and fast operation;
2. Circuit design with multiple security functions: power supply voltage monitoring, current limiting, automatic restart of terminal accidental crash, multiple lightning protection, anti-static damage, with extremely high safety and stability, supporting 7×24 hours of uninterrupted work;
3. The smart cloud system adopts Ai intelligent identification technology and has the function of terminal intelligent binding. The status of intelligent terminals will be automatically displayed on the main page of the system, and there is no need to add them one by one;
4. Remote firmware version upgrade, supports batch upgrade of the same type of equipment, supports single equipment upgrade; supports remote upgrade of smart cloud broadcasting system management software, no need for technicians to go to the local computer room, realizes zero maintenance of the client, and reduces the work intensity of maintenance personnel;
5. Each device has its own QR code identity information, and the mobile APP (mobile phone or tablet) software can establish a connection with the network broadcast server by scanning the QR code. The mobile terminal remotely controls the broadcast management interface, which can realize program playback, terminal name modification, system setting, volume adjustment and other operations (the device does not need to be pulled back to the computer room to configure one by one, which greatly shortens the device debugging cycle);

12. Support the forced insertion function of fire alarm. When the system receives the fire signal and enters the alarm mode, the terminal will force the maximum volume to play the preset fire alarm voice;
13. Set the reset button, and restore to the factory settings with one button;
14. Applicable to a variety of network environments: adopt TCP, UDP, unicast and multicast mixed transmission protocols, automatically switch in different scenarios, support static IP and DHCP, all terminals can cross routes, and are compatible with routers, cross-Internet networks, Switches, bridge gateways, Modem, Internet, 2G, 3G, 4G, audio fault-tolerant coding technology can work normally even in the case of 5% packet loss;
15. One-line multi-purpose: Standard RJ45 interface, it can be connected to places with Ethernet ports, make full use of existing network resources, avoid repeated erection of lines, and truly realize multi-network integration of broadcasting, computers, and monitoring networks;
16. Built-in network isolation and lightning protection processing circuit, supporting 15KVESD protection;
17. Anti-shock circuit, avoiding the sound of "pop, pop" when switching on and off;
18. The power amplifier has a fade-in and fade-out function. When the music starts, it will not suddenly be loud, and achieve a smooth transition effect;
19. Built-in environmental sound monitoring module for user selection;
20. The energy-saving and noise-reduction processing circuit automatically enters the dormant low-power consumption state when there is no signal input;
