The unit provides a range of benefits for those in the field who need to perform surveillance. The device uses the unique interferometric laser technology, which makes it a top choice for this type of work. It features an unseen infrared laser along with advanced DSP technologies. This allows for great speech detection and speech intelligibility even when the operating in noisy environments. This device has the ability to detect vibrations caused by speech at various angles and on many surfaces. It does not matter if the targets are inside the building (office, apartment, etc) or outside. The backscatter laser light frequency shift makes it possible for the speech to be extracted. This makes the technology fully robust to various surfaces and laser intensity. The unit has a fantastic operating range with minimum laser power, providing high performance surveillance, while still being safe. The device also happens to be quite easy to use.
APPLICATION:
The unit is used to perform surveillance and record speech of a person who might be up to 300m away, in a vehicle, building, or elsewhere. The microphone picks up on surface vibrations, and it has the power to do all of this independent from the target optical conditions. The laser is unseen by human eyes or common cameras. This allows users to target those in closed rooms through windows. During operation the system eliminates ambient interferences, noises.
How It Works The sensor can collect the vibrations in various surfaces, as mentioned. It can detect speech, and the best sensitivity occurs when objects are thin, soft, or lightweight. Some of the targets that could be used include papers, leaves on a plant indoors, pictures hanging on a wall, seat cushions, window panes, and clothing. The beam detects vibrations, turns them into an electrical signal and then amplifies them and creates an audible output. The vibrations, caused by a speaker, cause a backscatter laser light frequency (Doppler) shift. This shift is then extracted from the laser light. After that, the signal will pass through decoding and convertion to standard audio signal.
