Spy Audio Device Two-Way Auto Call Feature

Spy Audio Device Two-Way  Auto Call Feature comes with a manual switch located next to the SIM card slot. Switching to option (A) only allows you to call the spy audio device and listen in to conversations that are being detected. Option (B) allows the spy audio device to call you when it detects sounds, or if people are talking, while still allowing you the freedom to call the device and listen in to who’s talking. This feature makes it much more advanced than other GSM audio bugs on the market today.

Trying to find out the truth about what’s being said behind your back? Now you can and from anywhere in the world. You can even place several CVKA-G108 spy audio devices and set them up at your desired locations like your bedroom, living room, conference room or office. Just insert a SIM card into the audio spy device, send a text message containing the activation word, (GDA), followed by your cellphone number from your mobile phone, (e.g.GDA12346678910), then your bug is active and ready for action! The CVKA-G108 is a quad-band product that supports the four global standard GSM frequencies (850MHz, 900MHz, 1800MHz, and 1900MHz), so you can be confident of it working anywhere in the world.
