iSecus AJS-333

AJS-333 is a sound jammer integrated with Bluetooth speaker function. One of its functions is the ability to play music while jamming.

Use cases:
- private discussions between directors or senior managers,
- in small offices of law firms,
- financial advisors can use the jammer during personal meetings with clients,
- in negotiations involving confidentiality agreements or sensitive business transactions,

AJS-333 is portable because it is equipped with a lithium battery that can work continuously for more than 2 hours. So, for a private small meeting, this working period is enough.

AJS-333 can be turned on/off remotely with the remote control.

Ultrasonic jamming technology

Based on CPLD/FPGA with built-in encryption algorithm, it generates an ultrasonic mixing data model and exports ultrasonic signals, creating a harmonic effect to fool the recording device. The microphone/receiver can only receive the harmonic ultrasonic signal generated by the jammer, it cannot receive the normal voice signal. The recorded sound only reproduces noise, its content cannot be identified and cannot be analyzed by technical means (noise completely drowns out speech).

Ultrasound technology is widely used in many applications, such as parking radars and B-ultrasound. Ultrasound is basically a mechanical wave and does not radiate itself. However, it has strong directionality and high energy. When using it, try to avoid directing it directly to the ear. This may cause discomfort due to ear pressure.
