USA Sales Group CCTV Microphone Mini Plastic

Description

Product Overview

The USA Sales Group CCTV microphone is engineered for professional surveillance applications where audio fidelity matters as much as video clarity. Housed in a durable plastic shell, the mini‑form factor measures just 7 × 2.5 × 0.5 inches and weighs only 2.89 oz, making it unobtrusive when mounted on cameras or hidden in enclosures. It operates on a 6‑12 V DC power source and includes a 13‑inch cable with three connectors for flexible installation. Key specifications include a 2200 Ω impedance, 58 dB signal‑to‑noise ratio, and a frequency response spanning 300 Hz to 5500 Hz, delivering a balanced audio profile that captures speech and ambient sounds without distortion. The built‑in preamplifier boosts low‑output signals, while auto‑level and sensitivity adjustments adapt to varying acoustic environments, ensuring consistent performance across indoor offices, retail stores, and outdoor perimeters.

Usage

Designed for security professionals, this microphone excels in environments where reliable audio monitoring is critical. Install it on CCTV cameras in retail aisles to capture shoplifting conversations, mount it on perimeter cameras for perimeter breach detection, or integrate it with DVR systems in parking structures to record vehicle horns and engine noise. Its plug‑and‑play interface works seamlessly with devices that accept AV input, such as DVRs, VCRs, and standard televisions, eliminating the need for complex wiring or additional adapters.
The low‑profile design also makes it suitable for covert surveillance in corporate boardrooms or conference halls, where discreet audio capture supports compliance monitoring without drawing attention. For outdoor installations, the plastic housing resists moisture and dust, while the 1 Lithium‑Ion battery backup ensures uninterrupted operation during brief power outages.
