Area of use

The ultrasonic suppressor of voice recorders, mobile communications and the Internet «Ultrasonic-SpyLine-24-GSM» is specially designed for use in offices and meeting rooms to block unauthorized audio recording and data transfer.

The device is mounted under the leader’s table or negotiation table using special fasteners and does not attract attention when used. Ultrasonic suppression of voice recorders has a directional effect, which must be taken into account when installing the suppressor.

Features Stealth work! The device is installed under the negotiation table using a special mount in such a way that it does not attract the attention of the interlocutors and works silently.   You can record a conversation, but your interlocutors can not! Ultrasound emitters are arranged in such a way that only you can record on the recorder, while the recordings of other negotiators will be corrupted.   Ultrasonic suppression. The presence of 22 built-in ultrasonic emitters ensures suppression of recordings of any type at a distance of 10 meters.   Wireless suppression. The suppressor spreads interference in 8 radio frequency bands and blocks 3G and 4G mobile Internet, GSM 900/1800 cellular communications, GPS navigation, and Wi-Fi networks.   Remote control. The suppressor is controlled using the remote control, which allows using the device without attracting attention.   Battery operation (optional). The suppressor can be equipped with a built-in battery and operate autonomously for up to 2 hours, which will allow using it, for example, in field calls.   Protection against laser microphones (optional). At your request, this device can be equipped with special vibro-acoustic emitters that interfere with the remote reading of information from the window glass of the meeting room and provide reliable protection from laser microphones.
