Battery Powered or Mains Powered GSM Listening Device; with 40 feet audio microphone and remote live monitoring
This GSM Boom is professionally hand-made to extremely small dimensions (smaller than a matchbox) for easy deployment within the home, office or vehicle environment. The device is completely self-contained and portable, and has been professionally modified to achieve approx six (6) days standby time, PLUS a highly sensitive microphone with integrated noise filter to offer exceptionally clear audio approx 40 feet from where the device is placed / hidden.
