The most popular mini spy bug for room surveillance. Due to its miniature size, it can be hidden in many places. The antenna is very short, so it can be concealed even in a book! Powerful transmitter spying and bugging on the UHF band for achieving high audio and RF gain and maximal privacy. The range is approx. 200m in built area and up to 700m line of sight. Maximal drawn current: 30mA. Maximal RF output 14dBm. Super sensitive, only 6mm thick microphone.
