The device works using a GSM SIM card. Once powered, you can call it at any time to listen to the surrounding audio. The built-in VOX feature can trigger a call-back when sound is detected, keeping you informed without constant checking.

Its external power design gives you control over how long it runs. Connect it to a compatible battery or a 220V/12V power source depending on your setup. The device can also charge the connected battery when used with the included cable and adapter.

The wired Knowles microphone makes placement more flexible, letting you position the mic separately from the main unit. This improves audio capture while keeping the device itself discreet.
