Speco Technologies CAMMIC3.5 Line Level Microphone

Overview

The Speco Technologies CAMMIC3.5 is a compact line level microphone designed for audio integration with IP camera systems. This external audio pickup device enables integrators to add synchronized audio recording capabilities to CCTV installations where embedded camera microphones are unavailable or insufficient. The CAMMIC3.5 connects via a standard 3.5mm jack interface and operates on DC 12V power, making it compatible with existing camera power infrastructure in surveillance networks.

Key Features

• Audio Recording: Records audio for CCTV cameras with -65dB (±3dB @ 1 kHz) sensitivity for clear capture in typical surveillance environments
• 3.5mm Jack Interface: Standard 3.5mm connector simplifies integration with IP cameras and recorders that support audio input
• Line Level Output: RCA female jack output (2.2kΩ, 2V p-p) provides audio at line level for direct connection to camera or recorder audio inputs
• Integrated Cable: Includes 18-inch DC jack/audio cable, reducing field assembly requirements during installation
• Frequency Response: 30 Hz to 16 kHz bandwidth captures voice and ambient audio essential for situational awareness and incident documentation
• DC 12V Powered: Low power consumption of 10 mA operates from standard DC 12V power supply infrastructure common in surveillance installations
• Compact Form Factor: Dimensions of 2 x 0.6 x 0.6 inches (50 x 14 x 14 mm) enable discreet mounting in indoor monitoring applications
• Wide Operating Temperature: Functions across 14°F to 113°F (-10°C to 45°C), suitable for climate-controlled indoor environments with humidity tolerance up to 95%
• ONVIF Profile I Compatibility: Certified interoperability with ONVIF-compliant IP cameras and network video recorders
• Day/Night Capable: Operates in standard daylight and low-light indoor conditions with no special optical requirements

Integration and Compatibility

The CAMMIC3.5 integrates with IP camera systems through standard audio input connectors. Its ONVIF Profile I compatibility ensures seamless connection to a wide range of IP cameras and network recorders that support audio input. Integrators can deploy this microphone in multi-camera installations where audio synchronization with video is required for complete event documentation. The device pairs effectively with Speco camera platforms and third-party ONVIF-compliant systems.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The Speco CAMMIC3.5 addresses a common integration challenge: adding audio capture to IP camera systems without replacing the entire camera or deploying integrated audio-equipped models. During deployment planning for multi-location retail and office surveillance, this external microphone provides a cost-effective path to synchronized audio documentation. The -65dB sensitivity balances noise floor performance with practical indoor sound capture, and the integrated 18-inch cable reduces field assembly time significantly.

Technical Highlights:

• Audio Sensitivity: -65dB (±3dB @ 1 kHz) sensitivity standard captures conversational voice and ambient alerts in typical office and retail spaces
• Power Efficiency: 10 mA draw from DC 12V eliminates the need for separate PoE audio devices or complex power distribution; operates from existing camera power infrastructure
• Standard Connectors: RCA female jack output and 3.5mm input connector integrate with mainstream IP recorders and camera systems without special adapters
• Frequency Response: 30 Hz–16 kHz bandwidth covers critical speech and alert frequencies without requiring additional equalization

Deployment Considerations:

• Mount the microphone close to the point of sound origin to maximize signal capture and minimize background noise interference
• Verify that your target IP recorder or camera supports standard audio input before deployment; confirm ONVIF Profile I compatibility for best interoperability
• Plan cable runs during rough-in; the 18-inch integrated cable allows up to 18 inches of separation between microphone and camera/recorder without additional splicing
• Operate within the specified temperature range (14–113°F) to maintain sensitivity and avoid condensation in high-humidity spaces

The CAMMIC3.5 is a reliable choice for integrators who need to retrofit audio into existing camera deployments or add audio to locations where embedded microphones are unavailable. Its straightforward ONVIF integration and low power profile make it practical for distributed multi-location surveillance networks.
