ACTi PMIC-0100 Omnidirectional Audio Add-On Microphone
Overview
The PMIC-0100 is an active omnidirectional microphone built to add audio capture to network cameras that lack a built-in mic but expose a line-in audio input. If your camera line handles video well but leaves audio out of the recording — a common gap on older or budget dome and bullet models — this is the fix: an external mic instead of a camera swap. It picks up ambient sound in all directions, which matters at entries, cash wraps, and reception areas where you want context for what's on screen, not just directional pickup from one angle.
Compatibility
Manufacturer documentation specifies the PMIC-0100 for use with any camera that provides a line-in audio input, rather than a fixed list of camera models. Before ordering, confirm the target camera exposes a line-in audio port — cameras without one, including many models that rely on audio-over-network only, cannot use this microphone.
Installation Notes
The unit is powered over PoE, so it draws power from the same network run as the connected camera rather than needing a separate power adapter or local outlet — one less cable to route during install. Housing is white, which matters for ceiling or wall placements where you want the unit to disappear against light-colored finishes rather than stand out as an add-on.
Model PMIC-0100 ships from the manufacturer at a gross weight of 0.7 lb, light enough for discreet mounting near a camera without added bracket support. It carries a 3-year manufacturer warranty, in line with the surrounding ACTi accessory line. Pair it with cameras inside a broader ACTi IP camera deployment where audio evidence is a project requirement, and check a PoE planning guide before adding multiple powered accessories to an existing switch budget. For sites recording audio continuously, review your network video recorder channel and storage headroom, since synchronized audio adds to per-channel storage load. If you're auditing an existing camera fleet for audio gaps, a camera selection guide covers which models natively support line-in versus which need an external mic like this one.
