Ruth's sister

Ruth's sister Internal Power Cable DC12V High Sensitivity

SKU CH-8WKD-SVMHF

High-sensitivity CCTV microphone with RCA output operating on 9-12V DC power

  • High sensitivity pickup captures quiet audio with 200mA/ubar rating
  • Wide 100-6000Hz frequency range records clear sound across broad spectrum
  • Low 0.5mA minimum current draws minimal power from DC supply
  • 58dB signal-to-noise ratio delivers clean audio with reduced background hiss
  • Plug-and-play RCA output connects directly to CCTV monitoring systems

Surveillance Audio Pickup

The Ruth's sister DC12V microphone captures sound for CCTV systems with high sensitivity. It operates on a 9 to 12 volt DC supply drawing only 0.5 to 60 milliamps. The unit connects via an RCA female output for direct recording integration. Its compact 10 by 5 by 1 millimetre form factor suits discreet installations.

Installers Needing Covert Audio

This pickup suits security professionals adding sound to video feeds where space is limited. The wide 100 to 6000 hertz response captures speech clearly. Buyers requiring balanced XLR connections or phantom power should look at different microphone types. The fixed sensitivity of 200 milliamps per microbar cannot be adjusted for varying environments.

RCA Output Interface

The single RCA female jack is the only audio connection provided. It delivers a line-level signal compatible with most DVR and NVR audio inputs. Systems lacking an RCA audio input cannot use this device without an adapter. No other plug types or wireless interfaces are included.

Questions about this item

Should I choose the 9 V or 12 V supply for the DC12V microphone?

The microphone operates from 9 V to 12 V DC, so either voltage within that range will work.

What does the 58 dB signal-to-noise ratio mean for recorded audio?

A 58 dB signal-to-noise ratio indicates moderate background hiss; speech will be clear but faint sounds may be masked by noise.

Does the RCA female output limit the frequency response to 100 Hz–6 kHz?

The microphone itself is specified from 100 Hz to 6000 Hz; the RCA connector does not further restrict that range.
