LONGLIFE 20 PRO K+ is the newest addition in the LongLife GSM Spy Bugs series, equipped with an extended Knowles Microphone, providing crystal clear sound for up to 10 meters distance.
When connected to electricity, this GSM Spy Bug offers unlimited listening time. Alternatively, when left somewhere without a power supply, you can continuously listen in for 8-12 hours. In standby mode, it lasts 16 - 20 days, and thanks to the Voice Activation call-back function, you can listen in only when sounds are present, such as talking in the bug's surroundings.
The LONGLIFE 20 PRO K+ features an extended Knowles microphone that ensures
clear audio within a 10+ meter radius, ensuring you don't miss anything important happening around the device.
Its minimalist design allows for
easy installation and reliable use, and the 3M mounting system further simplifies the process. Plus, it can easily blend into any setting due to its discreet appearance.
Setting up requires only a SIM Card. After inserting the SIM Card, you call the device. Following the setup, you can call the device anytime and listen to everything near its vicinity, and the voice activation can be remotely powered on/off via SMS commands.
Compared to the
LONGLIFE 60, the LONGLIFE 20 PRO K+ provides superior audio quality and increased range, despite its shorter battery life.
Other options within the series include the
LONGLIFE 20 and
LONGLIFE 20+ which offer the same listening times as the LONGLIFE 20 PRO K+ but with lower audio quality and a shorter range.
