Our flagship extended operating time Audio Surveillance Transmitter, the V2TX. Inspired by Ecologists and wildlife researchers looking for a more powerful transmitter for wildlife studies, the need to observe habitats and soundscapes of different species without disturbing their environment is paramount, remote audio surveillance of these species opens many doors not previously available. The same principle applies to monitoring different subjects of interest. Enhanced and powered by a formidable 20mW of RF, this transmitter is designed to transmit ambient audio continuously for an impressive duration of 8 days. As a permanent, always-on "hot-microphone," it initiates live transmission of ambient and surrounding audio immediately upon battery insertion, utilizing the Ultra High-Frequency band for uninterrupted transmission. V2TX is now available with a new extremely sensitive KNOWLES microphone, and a new high-powered crystal generating 20mW of RF power, ensuring superior frequency stability and delivering enhanced audio sensitivity.
In challenging urban environments, the V2TX excels with a remarkable broadcasting range of 700 meters, extending up to 1.2 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 two AA Alkaline batteries, the V2TX offers extended operating time while maintaining optimal performance. It allows for prolonged periods of discreet acoustic monitoring, making it ideal for remotely listening to areas of interest.
To fully utilize the V2TX's capabilities, we recommend using any handheld UHF receiver capable of tuning into the standard frequency range of 400MHz-700MHz. This range is supported by most UHF receivers. As our recommended handheld receiver, we suggest the Baofeng UV-5R, known for its reliability and performance. Rest assured, your V2TX will arrive with its specific Tx/Rx frequency clearly indicated on its back, ensuring seamless compatibility with your chosen receiver.
