Designed for discreet audio surveillance, the Cellular Audio Monitoring Device from Avangard Optics allows you to monitor audio from remote locations. The device is compatible with GSM SIM cards (available separately) and requires one to operate. Featuring two detection modes, the unit can be set to passive mode, which allows you to call the device and listen to nearby sound, or active mode, which allows it to call your connected smartphone when audio is detected. While in active mode, you can still call in to the device.
