Extended Memory Capacity for Long-Term Audio Intelligence

When conducting multi-week security audits, logging client meetings, or preserving crucial verbal evidence, running out of memory mid-deployment is not an option. The MQ-16U350 USB Spy Audio Recorder solves storage bottlenecks by packing 16GB of onboard flash memory directly into a discreet USB flash drive casing.

With the ability to archive up to 576 hours of audio and sit on 25-day standby in voice-activated mode, this device is engineered for maximum operational field life. Simply place it on a desk, clip it to a keychain, or leave it plugged into a PC port. It wakes up instantly when voices are detected and pauses during quiet periods, keeping your audio logs clean, organized, and complete.
