DC 12V Sensitive Sound Pickup Microphone for Security Camera System, Compact Wide Range Audio Sensor

Sound Monitor Key benefits Compact, lowpower audio sensing module for monitoring ambient sound across small to medium areas. Simple integration with DC 9V to 12V systems using three wires for power and audio input, reducing installation time. Delivers a usable output level up to 06 Vpp with a stable frequency range for reliable signal transmission to recorders, amplifiers, or control systems. Durable alloy housing and standard mounting dimensions make it easy to install in panels, enclosures, or surface mounts. What it does and why you need it Continuously detects and converts sound into an electrical output that can be read by audio equipment, monitoring circuits, or alarm systems. Useful when you need an independent audio sensing module with predictable output and low current draw for alwayson monitoring applications. Sized and specified to cover spaces from about 5 square meters up to 150 square meters depending on placement and acoustic conditions. Key specifications Material: alloy housing and electric parts Power supply: DC 9V to 12V Work current: 12 mA Frequency range: 200 Hz to 10 kHz Output level: 0 to 6 Vpp Frequency response: 2.5 dB Output impedance: 600 Ohm Monitor area: approximately 5 m2 to 150 m2 Size: 4.9 x 4.5 x 1.8 cm (1.9 x 1.8 x 0.7 inches) Mounting hole size: 5 x 3.8 mm (0.2 x 0.15 inches) Cable length: 15 cm (5.9 inches) Wiring: red/black = positive and negative power supply, white = audio input Practical applications Room noise monitoring: Install in meeting rooms, classrooms, or open offices to feed audio level information to a monitoring system or recorder. Security and alarm systems: Use as an audio trigger input for event detection or combined sensor setups where sound verification is required. Audio equipment integration: Provide a conditioned audio output to small amplifiers, mixers, or data acquisition modules in compact installations. Installation notes Supply DC 9V to 12V at the red and black wires, and feed the audio source to the white wire. Mount using the provided hole dimensions for a secure fit; the compact size fits tight enclosures. Observe the specified frequency range and output impedance when matching to downstream equipment for performance. This Sound Monitor offers a compact, lowpower solution for consistent sound sensing and straightforward integration into a variety of monitoring and audio systems.
