Our Original Audio Surveillance Transmitter permanently mounted inside a water-resistant ABS enclosure, with a butyl-rubber dipped and textured coating for longevity, featuring an external waterproof microphone.

The enhanced internal V1TX is designed for unparalleled performance, this transmitter operates as a permanent, always-on "hot-microphone," initiating live transmission of ambient and surrounding audio immediately upon battery insertion. It seamlessly operates on the Ultra High-Frequency band, ensuring uninterrupted transmission.

Measuring a mere 40x70mm when fully mounted, with a thickness of 17mm and weighing less than 12 grams, the WTX6 may be compact, but it delivers exceptional capabilities. It generates a formidable RF power of over 25mW, enabling continuous audio surveillance for an impressive duration of 25-30 hours.

In challenging urban environments, the WTX6 boasts a broadcasting range of 700 meters, extending up to 1.5 kilometers with Line-of-Sight (LOS) transmission. It effortlessly penetrates obstacles such as concrete, drywall, and dense foliage, ensuring reliable audio transmission to any UHF receiver.

Powered by a single button cell battery, this transmitter is the perfect choice for discreet acoustic monitoring of areas of interest. We recommend utilizing any handheld UHF receiver capable of tuning into the standard frequency range of 400MHz-434MHz. For optimal performance, we suggest the BAOFENG UV-5R as our recommended handheld receiver. Your WTX6 will arrive with its designated Tx/Rx frequency clearly indicated on its back.
