2-Wire surveillance kits are designed with the earpiece located on one wire and the microphone and push-to-talk on the second wire. Ideal for overt operations, personnel can fasten the microphone to their uniform where it’s easily accessible. Or, hold it directly in front of the mouth while speaking into it, which is especially beneficial when speaking in a low voice. Motorola's state-of-the-art IMPRES technology provides adaptive audio, providing clear communication whether you are working in a loud or quiet environment.
