Audited Supplier This AAT- SJ -miniS recording shield is a highly integrated high-tech personal safety protection product independently developed by AL ASAR TECH. When the illegal elements use recording equipment (such as mobile phones, recording pens, recorders, etc.) to record you, the recording shield will generate random noise signals, which can produce suppressive interference on speech signals, so that only noise information can be picked up by recording equipment, but it can not distinguish voice information, so as to ensure the safety of voice information. Widely used: leaders, bosses, stars and other high-end personal needs.
1. This product uses radio frequency signal shielding recording equipment, so a little sound after opening is normal, according to the age of the response to the sound is different, this sound has no impact on the human body.
2. When testing, we should simulate the real use environment, communicate with normal volume, and do not need to increase the volume intentionally. This product takes into account its own noise and actual shielding distance, and adopts the best software version. If there are special needs, we can ask for a special version of the software!
