Algo | 8420 | IP Dual-Sided 15.6" LCD Screen Display with Speaker IP Dual-Sided Visual Display Speaker for Visual and Audible Alerting and Notification. Algo’s 8420 IP Dual-Sided Visual Display

<p>The Algo 8420 is a high-performance, dual-sided IP visual display speaker designed for effective communication in large open spaces, hallways, and corridors. This SIP-compliant device integrates two 15.6" wide-angle LCD screens, high-intelligibility speakers, and multi-colour LED flashers to provide a comprehensive notification solution. Whether used for emergency alerting, public address, or day-to-day informational messaging, the 8420 ensures your message is seen and heard from both directions with absolute clarity.<br><br>The dual LCD screens offer unlimited visual possibilities, supporting scrolling text, full-colour images, and digital or analogue NTP-synched clocks. With a viewing angle of 88° in all directions and over 16 million colours, the display remains vibrant and legible even from off-axis positions. This makes it an ideal choice for Australian schools, hospitals, and transport terminals where clear, instantaneous visual communication is critical for safety and operational efficiency.<br><br>Audible communication is equally robust, featuring wideband HD voice and a maximum SPL of 106dBA. An integrated omnidirectional microphone enables ambient noise response, allowing the speaker to automatically adjust its volume based on the surrounding environment. It also supports two-way talkback, allowing staff to communicate back to a central monitoring station during an event. This combination of audio and visual cues ensures that notifications reach all individuals, including those in high-noise areas or with hearing impairments.<br><br>Designed for modern IT environments, the Algo 8420 is powered via PoE++ for simple single-cable installation and features secure SIP protocols like TLS and SRTP. It supports multicast scalability, allowing a single device to broadcast to many endpoints across a campus. With a durable build and a 12GB internal memory for storing custom WAV and MP3 files, the 8420 is a reliable and versatile addition to any unified communications platform.</p><h3>FEATURES</h3><ul> <li>Dual 15.6" wide-angle full-colour LCD screens for two-way visibility</li> <li>High-visibility multi-colour LED flashers (Red, Amber, Green, Blue)</li> <li>Wideband HD voice (G.722 codec) with 106dBA maximum SPL</li> <li>Ambient noise response for automatic volume adjustment</li> <li>Integrated microphone for two-way talkback and monitoring</li> <li>SIP compliant and multicast capable (RTP, Poly, InformaCast, Revolution)</li> <li>PoE++ powered for easy installation via standard network cabling</li> <li>12GB onboard storage for custom images and audio files</li></ul><h3>SPECIFICATIONS</h3><ul> <li><strong>Screen Size:</strong> Dual 15.6" LCDs (1920x1080 resolution)</li> <li><strong>Viewing Angle:</strong> 88° (Horizontal and Vertical)</li> <li><strong>Audio Power:</strong> 16W Maximum</li> <li><strong>Maximum SPL:</strong> 106dBA at 1m</li> <li><strong>Frequency Response:</strong> 150-19,000Hz</li> <li><strong>Microphone:</strong> Omnidirectional, 360° pickup</li> <li><strong>Storage:</strong> 12GB (WAV, MP3, JPG, PNG supported)</li> <li><strong>Network:</strong> IPv4, IPv6, DHCP, VLAN, LLDP</li> <li><strong>Security:</strong> TLS, SRTP, MTLS, IEEE 802.1X</li> <li><strong>Power Input:</strong> PoE++ 802.3bt Type 4 (71.3W) or Type 3 (51W)</li> <li><strong>Minimum Power:</strong> PoE+ 802.3at (25.5W) - Performance reduced</li> <li><strong>Operating Temp:</strong> 0 to +40°C</li> <li><strong>Dimensions:</strong> 48.8cm x 23.7cm x 7.4cm</li> <li><strong>Weight:</strong> 4.5kg (Product only), 5.4kg (With bracket)</li></ul><h3>WARRANTY</h3><p>1-Year Limited Warranty</p>
