40 Watt 8 Inch High Power Talk/Listen Paging Horn (Integrates into IP-Based Digital CCTV Security Cameras)

The TLO-A (LE-087) is intended for 2-way communication in both Indoor/Outdoor large coverage applications. Our sensitive ECM microphone provides superior sound capture while minimizing background noise. The high-powered Class D 40-watt amplifier with an inverted horn delivers high-volume penetration in a single, weather-resistant housing. The TLO-A provides both listen and talk-back capabilities while its internal operating technology eliminates the need for a mid-span audio amplifier. The product integrates an omnidirectional microphone that picks up audio within a 30-foot diameter and can be configured to integrate with, NVRs that use VMS (Video Management Systems). Connect to existing IP-based Digital CCTV Security Cameras that support line-level audio input/output capabilities to the TLO-A. Requires external 24Vdc power connectivity, (DC Power Supply Included).
