Description
Pixel Nano 4G enables remote audio monitoring using a simple call from a telephone or smartphone. After initial set-up via SMS, the unit can automatically call back the control number when activity is detected (voice/noise or motion, depending on configuration).
Set-up and call access can be protected by password. The module core supports 4G/LTE operation and can also operate on GSM networks where 4G coverage is not available.
The system can be supplied with different Li-ion battery sizes and microphone options (including waterproof versions where required). The module can also be integrated into selected appliances or concealment solutions depending on operational needs.
