Speco CAMMIC Line-Level Microphone Audio Pickup

Speco Technologies CAMMIC Line Level Microphone

Overview

The Speco CAMMIC is a specialized add-on microphone designed to expand audio recording flexibility in security surveillance systems. Unlike standard microphone-level units, the CAMMIC connects directly to line-level inputs on amplifiers and DVRs, solving a critical integration challenge: providing audio capture when all microphone inputs are occupied or unavailable. This makes it especially valuable for DVR systems with channel-specific audio recording capability. The CAMMIC operates as a 12VDC powered condenser microphone with a 1.5-foot integrated power/audio cable and 10K ohm high impedance design.

Key Features

• Line Level Output Capability: Connects to line-level inputs on amplifiers and DVRs instead of dedicated microphone inputs, providing flexibility when microphone inputs are fully utilized or unavailable
• High Sensitivity Condenser Design: Delivers -62dB ± 3dB sensitivity rating for reliable audio capture across security applications
• Omni-Directional Pickup Pattern: Captures audio from all directions, ideal for open floor surveillance and general area monitoring
• Compact Form Factor: Mini microphone design weighs 0.1 lbs with 1.5-foot integrated cable for easy installation in tight spaces or multiple camera deployments
• Wide Frequency Response: 20Hz to 16kHz frequency range ensures clear voice recording and audio event capture across the security spectrum
• 12VDC Power Operation: Requires external 12VDC power supply (not included; Speco PSW5 optional accessory available)
• Maximum Audio Output: 2Vp-p output level compatible with standard line-level amplifier and DVR inputs
• NDAA Compliant: Meets Section 889 Part B compliance requirements for federal and regulated procurement environments
• Universal Security Application Support: Engineered specifically for DVR voice recording, surveillance audio documentation, and access control audio verification

Integration and Deployment

The CAMMIC solves a common integration problem in multi-camera systems: when DVR microphone inputs reach capacity or when amplifier audio routing requires line-level signal sources. The high impedance design (10K ohms) ensures clean signal integration without impedance mismatch issues common to consumer-grade microphones. Maximum power consumption of 10mA makes the unit suitable for systems using shared or limited power budgets. The 2Vp-p output specification ensures adequate signal level for professional DVR line inputs without requiring additional preamplification.

Installation is straightforward: connect the integrated power/audio cable to a 12VDC power source and route the audio output to any available line-level input. This flexibility enables system integrators to add audio recording capability to existing installations without rewiring camera circuits or adding dedicated microphone infrastructure.

The CAMMIC addresses a genuine integration pain point that emerges in mature surveillance deployments. I've evaluated this unit during system expansions where DVR microphone inputs were exhausted but audio recording remained a requirement. The line-level output design eliminates the need for additional microphone preamplifiers and simplifies cable routing in constrained installations.

Technical Highlights:

• Line-Level Integration: The CAMMIC's unique line-level output architecture means you can route audio directly to amplifier or DVR line inputs without additional signal conditioning, reducing component count and failure points in the audio chain.
• Condenser Sensitivity: At -62dB sensitivity with omni-directional response, the CAMMIC captures speech and alarm audio reliably across typical security coverage areas without hot-micing or excessive cable runs.
• Power Efficiency: 10mA current draw integrates cleanly into shared 12VDC power loops, important in field deployments where dedicated power drops are unavailable.

Deployment Considerations:

• Verify that your DVR or amplifier has available line-level inputs before specifying the CAMMIC—this is not a substitute for true microphone inputs on units that lack them entirely.
• Order the optional PSW5 12VDC power supply as part of your bill of materials if your installation does not have existing regulated 12VDC distribution.
• NDAA compliance makes this unit immediately deployable in federal and government procurement workflows without compliance review delays.

For integrators managing multi-camera installs where audio becomes a late-stage requirement, the CAMMIC is a practical solution. The compact form factor and integrated cable reduce installation time, and the line-level design keeps the audio architecture simple. Recommended for DVR systems with channel-specific audio recording capability and situations where microphone input expansion is needed.
