Product Description
The CCTV High-Gain Microphone - Indoor/Outdoor Audio Module with RCA & 2.1mm Jack (MPN MIC-IN-LINE-YELLOW) adds a sound channel to a camera system. Here is what each spec means in practice.
Spec by spec
- Electret microphone with built-in amplifier: picks up ambient sound and boosts the signal. It covers a wider area than a passive microphone.
- RCA audio output: an analogue audio connector. It feeds a DVR (digital video recorder) or NVR (network video recorder) that accepts audio input via RCA.
- 12V DC power, 2.1mm DC jack: direct current through a jack that matches common CCTV power supplies. The module can share power infrastructure with cameras or other auxiliary equipment.
- Compact module: small enough to sit inside a junction box, camera housing or equipment cabinet.
- Indoor and sheltered outdoor use: suits entrances, retail counters, offices and warehouses.
What else you need
- A recorder with an RCA audio input. Without one, the module has nowhere to connect.
- A 12V DC supply that ends in a 2.1mm DC jack.
- A sensible mounting spot. Keep it away from strong airflow or vibration sources to get better recordings.
