The SEL-225 "Sentry" desktop field indicator is designed to quickly detect any eavesdropping devices in the workplace (office, study) that use a radio channel to transmit information, such as:
• analog or digital radio microphones and wireless video cameras;
• phones operating in DECT, GSM, 3G or 4G transmission mode;
• Wi-Fi and Bluetooth devices.
The "Sentry" indicator is built into a natural stone writing set and does not give away its main purpose in any way. It operates autonomously from a built-in battery and has a multi-color LED indicator to notify of an alarm when detecting analog and digital transmitters.
For an optimal sensitivity level, the indicator is equipped with an automatic adjustment button.
