Professional 3G GSM bug with two microphones Knowles vc1247

Description This is the latest high-tech listening device on the market at the moment. It is the work of the Czech company StealthTronic, which has established itself as an authoritative brand in the sector, thanks to its quality products. The model combines parameters that are many times higher than all other competing devices. It stands out for the two most important characteristics for this type of device, namely sound quality and battery life. It works with a nano SIM card that receives and sends messages with the appropriate settings. The listening itself is done by dialing the number and the spy device automatically picks up. The sound quality is improved by using two Knowles microphones, one of which is both MEMS technology and 3G mobile network. The first is located on the surface of the housing and serves the voice activation function. The other is externally mounted and provides a greater range of audibility in a range of up to 12 meters. The exceptionally high sound quality is due to the good combination of two technologies. Digital preamplifier working with AGC, work together so that a very weak signal can be amplified, as well as a very strong signal to be set to the required level. Another feature contributing to the good sound and easy adjustment of the quality of the transmitted signal for real-time eavesdropping is DTMF tones. This function is controlled via the phone keypad. When you dial the number of the SIM card inserted in the spy gadget, after listening begins, by pressing the phone keypad you will be able to change the microphone settings. CHOOSE BETWEEN THREE OPERATION MODES There are three operating modes, from which you can choose the most appropriate one for the specific situation. The first is deep sleep, when you want the battery to last longer, by remotely choosing when to activate the working process. The second is for real-time listening, and the third for voice activation. In the first case, the device is turned off and is activated only on command. It is suitable when you want a discreet inactive bug that will be available for a long time when needed. The battery can last up to 150 days. The second option is to listen in real time. In this situation, you can count on approximately 18 hours of continuous operation. The third option is to choose voice activation and then listening occurs only when a conversation is detected, and the rest of the time it is in standby mode. The battery can last about 25 days depending on how often it detects sound. AUTOMATIC RESTART FUNCTION StealthTronic has thought of absolutely everything, even in the event that for some reason a problem occurs and the bug freezes and stops working for no objective reason. When the problem is detected, the module automatically restarts and starts working again.
