Description Dahua DH-HAP120 Omni-Directional Microphone Capturing clear audio alongside video enhances surveillance evidence and enables two-way communication. The Dahua DH-HAP120 is a high-sensitivity omni-directional microphone designed for CCTV applications. With a coverage area of 10 to 70 square metres and built-in protection circuitry, this compact microphone delivers clear, natural sound for integration with Dahua cameras and recorders. Omni-Directional Audio Capture The omni-directional pickup pattern captures sound equally from all directions, ideal for monitoring rooms, retail spaces, and open areas where audio sources may be positioned anywhere within the coverage zone. This eliminates the need for precise aiming required by directional microphones. High-Sensitivity Performance Sensitivity of -34 ± 3 dB with a plated film capacitor microphone head captures voices and sounds clearly across the 10 to 70 square metre coverage area. The 80 Hz to 16 kHz frequency response reproduces natural, intelligible audio suitable for voice monitoring and evidence recording. Wide Dynamic Range A 74 dB dynamic range handles both quiet conversations and louder sounds without distortion. Maximum sustainable sound pressure of 110 dB SPL ensures the microphone performs reliably even in noisy environments without clipping or damage. Built-In Protection Lightning protection, power polarity transposition protection, and electrostatic protection safeguard the microphone from electrical damage. These features ensure reliable operation in environments where power surges or static discharge may occur. Compact Design The aluminium housing measuring just Φ40mm x 20mm and weighing only 48g enables discreet installation alongside cameras or in ceilings. The silver finish provides a professional, unobtrusive appearance suitable for offices, retail, and commercial environments. Easy Integration RCA female connector provides standard audio connection to Dahua cameras, NVRs, and XVRs with audio input capability. Separate DC power connector accepts 12 VDC supply with low 40 mA current consumption. The wide operating temperature range of -30°C to 70°C suits indoor and sheltered outdoor installations.

Omni-directional microphones capture sound equally from all directions, making them ideal for monitoring rooms and open areas without requiring precise positioning toward specific sound sources. What coverage area does this microphone support? The microphone effectively captures audio across areas from 10 to 70 square metres, suitable for small offices through to larger retail spaces and meeting rooms. How does this microphone connect to my system? An RCA female connector provides standard audio connection to cameras, NVRs, or XVRs with audio input capability. Separate 12 VDC power is required via the DC power connector. What protection features are included? Built-in lightning protection, power polarity transposition protection, and electrostatic protection safeguard the microphone from electrical damage in demanding environments. Is this microphone suitable for outdoor use? The wide operating temperature range (-30°C to 70°C) suits sheltered outdoor locations, though the microphone should be protected from direct weather exposure.
