Is each micro spy equipped with a sound detector?


No, not all micro-espions are equipped with a sound detector. Some micro-espions operate continuously, recording everything in their environment. Other micro-espions are designed to start recording only when they detect a sound, which can be useful to save memory or save only important moments. It is important to read the product specifications to know if it is equipped with a sound detector before buying it. It is also important to respect local privacy and surveillance laws.
