Description
Axis C1511 Network Pendant Speaker
The Axis C1511 is a professional-grade network pendant speaker engineered for intelligent IP-based audio distribution in security, public address, and communication systems. Combining advanced digital signal processing with robust network protocols, this speaker delivers clear, intelligible audio across indoor environments while integrating seamlessly into networked surveillance and access control infrastructures.
Key Features
- 4-inch broadband dynamic cone speaker with 93 dB maximum sound pressure level
- 130° coaxial coverage pattern for even audio distribution
- Built-in 7W Class D amplifier with pre-configured digital signal processing
- Built-in microphone (disableable) plus external microphone and line-in support
- One-way and two-way audio streaming with optional half-duplex echo cancellation
- SIP VoIP integration for seamless PBX/SIP system connectivity
- PoE-powered for simplified cabling and network delivery
- IP40 weather-sealed casing suitable for varied indoor environments
Audio Performance & Specifications
The C1511 delivers professional audio quality with frequency response spanning 70 Hz to 16 kHz and built-in microphone sensitivity from 50 Hz to 20 kHz. Advanced audio encoding support includes AAC LC, G.711 PCM, G.726 ADPCM, WAV, and MP3 formats at variable bit rates up to 320 kbps, accommodating diverse streaming and recording scenarios. The coaxial design ensures consistent 130° audio coverage, making it ideal for retail floors, office atriums, hallways, and educational facilities.
Management & Control
AXIS Audio Manager Edge is built-in, providing content management, scheduling, and message prioritization to ensure urgent announcements override scheduled content. Integration with larger systems is supported via AXIS Audio Manager Pro (sold separately) and AXIS Audio Manager Center cloud service. The device supports open APIs including VAPIX® and AXIS Camera Application Platform (ACAP) for custom software integration.
Network & Security
Dual IPv4/IPv6 support with comprehensive protocol suite (HTTPS, TLS 1.2/1.3, SSH, SFTP) ensures enterprise-grade security. IEEE 802.1X network authentication, AES-256 SD card encryption, and signed OS firmware provide multi-layer protection. QoS Layer 3 DiffServ enables prioritized audio traffic on congested networks.
Installation & Reliability
The pendant design with hook mounting fits seamlessly into ceilings and suspended environments. Built-in test tone verification and Auto Speaker Test via microphone streamline commissioning. Designed for 24/7 operation across -30°C to 50°C temperature range with 5-year warranty and comprehensive EMC/safety certifications (UL 62368-1, EN 62368-1, FCC Part 15 Class B).
