Ruth's sister 5-pack sensitive microphone DC power cable

SKU CH-7KJN-0TPHH

Five-piece set of sensitive DC-powered microphones with built-in DSP noise reduction for CCTV security cameras

  • Capture audio up to 120 metres away with high-gain pickup
  • Built-in DSP noise reduction circuit delivers clear recordings
  • Auto level adjustment maintains consistent volume across 200 to 10kHz range
  • Five cables included for multi-camera security installations
  • Operates on DC 6V to 12V with low 25mA current draw

Five-pack security microphone cables

This set contains five DC power cables designed for sensitive microphones used in CCTV and DVR camera installations. Each cable integrates a built-in DSP noise reduction circuit, on-board IC preamp and coupling capacitors for low-noise, high-gain audio capture with automatic level adjustment. The 2 mm pinhole design and surface bump structure help minimise reflections during operation. The pack provides a ready-to-wire solution for multi-point surveillance audio.

Installers wiring multiple indoor pickups

The cables suit installers who need several identical microphone feeds running from a single 12 V DC supply, with each unit drawing only 25 mA and transmitting signals up to 800 metres. They are not intended for outdoor exposure, phantom-powered studio gear or systems that require balanced XLR connections. Buyers needing longer runs, weather-sealed housings or different connector types should look at alternative products.

12 V DC operating voltage

Every microphone in the set operates on a 6 V to 12 V DC range with a nominal 12 V supply, making voltage compatibility the single specification that determines whether the cables match the existing power infrastructure. The output level spans 0 to 6 V with 600 ohm impedance and a 200 Hz to 10 kHz frequency response at 2.5 dB. Confirm the recorder or DVR accepts this signal level before purchase.

Questions about this item

How can I verify the microphone is functioning correctly after connecting it to my CCTV DVR system?

Connect the cable to a 12V DC power source, then check the DVR audio input for a clear signal within the 200 to 10kHz frequency range and listen for the built-in DSP noise reduction to suppress background hiss.

What exactly is included in the package and what additional items are required for installation?

The pack contains five sensitive microphone units with integrated preamp circuits and 2mm pinhole housings; you must supply a 12V DC power source and compatible DVR or camera inputs separately.

Which version or capacity should I select for a standard security camera setup?

Only one version is offered — a five-piece set of identical microphones rated for DC 6V to 12V operation with 25mA current draw and 800-meter transmission distance.
