Sound Projector

The Tonmind SIP-S51 Sound Projector is a compact yet powerful IP-based speaker designed to deliver highly directional and intelligible audio in public environments. As a specialized Sound Projector Speaker, it offers a focused sound projection ideal for voice announcements and background music across transit hubs, school corridors, shopping centers, factories, and other indoor and semi-outdoor public venues.

This Sound Projector is fully compatible with SIP-based VoIP systems and ONVIF-compliant IP surveillance systems. Supporting dual SIP accounts, SIP direct IP calls, and RTP multicast, it integrates easily with IPPBX, IP phones, and camera VMS/NVR platforms, enabling seamless communication and security coordination.

With a built-in 15W amplifier and advanced codecs like OPUS (48 kHz), G.722, and MP3, the Sound Projector ensures crystal-clear audio with a maximum SPL of 102 dB and minimal distortion. Technologies such as Acoustic Echo Cancellation (AEC), Automatic Gain Control (AGC), and Automatic Noise Reduction (ANR) contribute to excellent sound quality in various acoustic environments.

The unit includes an Alarm In interface, allowing external systems such as fire alarms or emergency buttons to trigger pre-recorded messages or alert sounds. This makes the Sound Directional Speaker not only suitable for daily broadcasting but also for emergency notification systems.

Constructed from IP55-rated waterproof ABS material, the speaker is designed for durability in demanding conditions. Its clean, cylindrical form and neutral tone make it a visually pleasing option for wall-mounted installations in both modern and traditional architecture.
