Phantom
The PHANTOM is an ultra‑sensitive spy fiber‑optic microphone designed for discreet applications in environments subject to strong electromagnetic interference. With no metal components or local power supply, it is completely undetectable, operates solely on light, and can be deployed more than 10 km from its electronic unit. Its high‑sensitivity version delivers exceptional voice‑listening quality thanks to noise reduction and built‑in SD‑card audio recording.
This housing is used with an all‑plastic Evotis microphone. It provides SD‑card recording (controlled via the front‑panel button to start recording) or can be operated in VOX TRIGGER and TIME TRIGGER modes via a program stored on the SD card. The unit can also be controlled via Ethernet through the RJ45 connector.
It includes a battery that provides 24 hours of listening.
