Blueline Sensors LLC released the WASP2 Tactical Contact Microphone. These compact microphones can fit in the palm of your hand but instantly attach to steel doors with built-in high-strength magnets, other building partitions such as drywall or wood floors with extreme-weather adhesive tape mounts, and glass windows with small suction cups. The contact mics detect whisper-level sounds through wall, doors, windows and floors, providing critical incident negotiation teams (CINT) with enhanced situational awareness and SWAT entry teams the time-critical intelligence required to enhance officer safety. The WASP2 mic has a built-in 30 foot long cable and can drive available extension cables up to 1000 feet long, providing secure standoff operation from remote monitoring locations or incident command vehicles.
These high-tech microphones operate by converting the imperceptible strains in a building partition created by nearby sounds directly into electrical signals. The tiny signals are amplified to a high level suitable for input to recording equipment, radios, or real time monitoring with headphones. Unlike conventional or under-door microphones, WASP2 mics do not require an opening or air-path to carry sound from the incident scene to the operator. Therefore, alerting the suspect by drilling a tell-tale hole, or otherwise exposing the operator to the incident scene is not required. Each microphone is fitted with a 3.5mm mini-phone plug ready to work with most “mic-input” audio devices (audio recorders, radio, etc). Adapters are available for use with most Android or Apple smartphones and complete tactical audio kits, containing one or more WASP2 mics, a digital audio recorder, noise-isolation headphones and all mounts and accessories are available.
