Overt Audio Surveillance
Live Audio Monitoring
To enhance your surveillance capabilities, we offer powerful UHF/VHF transmitters capable of transmitting ambient audio in real-time over long distances, for extended periods ranging from hours to months. Remotely monitor critical situations and gather crucial information, even in challenging environments.
Covert Audio Surveillance Is Here
GR-SATX provides unparalleled capabilities for remote audio surveillance from any location worldwide. With both overt and covert models available, the GR-SATX is unaffected by range, signal loss, and other constraints typically associated with conventional VHF/UHF audio surveillance devices.
Asset Tracking
To facilitate robust tracking and monitoring of remote assets, we offer state-of-the-art subscription-free GPS trackers and VHF transmitters.

SUPERB AUDIO FROM A TINY TRANSMITTER
We are proud to offer our smallest Audio Surveillance Transmitter, which is a remarkable feat of miniaturization, measuring just 6.3x18mm when fully mounted with a thickness of only 0.8mm and a weight of less than 7 grams. Despite its compact size, this audio transmitter is capable of delivering powerful and reliable performance, making it an ideal solution for a wide range of audio surveillance applications.
TRUE RANGE
Up to 1km range in an open field, and upwards of 700 metres in an urban environment. Penetrates drywall and concrete, even through dense bush and valleys.
RAPID DEPLOY
No programming required, no switches, no indicator lights. Our transmitters begin broadcasting audio once the battery is inserted.
CLEAR AUDIO
A highly-sensitive omnidirectional MEMS microphone along with a microphone amplifier are both on-board, providing crystal clear audio.
FOR COVERT SURVEILLANCE
The V1TX is a flagship model, representing the first audio surveillance transmitter we introduced, and has remained one of our most popular options to date.

THE SURVEILLANCE CARD
The sleek and compact design of our business card-like transmitter boasts an integrated PCB trace antenna, which eliminates the need for an external antenna while providing exceptional transmission capabilities.

L1TX
For users seeking an extended operating time, the L1TX offers an impressive 290 hours, or 12 days, of uninterrupted ambient audio surveillance.

L2TX
The L2TX is our most compact audio surveillance transmitter, offering an extended operating time with the use of a powerful CR123A Li-Ion battery.

V2TX
The V2TX is a compact and reliable audio surveillance transmitter that boasts exceptional audio pick-up. Utilizing two readily available Alkaline AA batteries, the V2TX provides over a week of uninterrupted audio surveillance.
Anything Can be a Listening Device.
The most effective listening device relies on the principle of security through obscurity. Our custom surveillance devices are designed to provide reliable and covert surveillance capabilities for our clients. We offer a range of powerful and cleverly disguised transmitters that can be customized to meet your specific requirements, just contact us.

WIRELESS ANALOG TRANSMISSION
TINYTX's UHF & VHF transmitters are easily paired with any compact hand-held transceiver. Any Two-Way UHF Radio will work, but we recommend the BaoFeng UV-5R from FengBros.

SDR COMPATIBLE
Audio/signal from our transmitters can be received using any inexpensive SDR USB dongle. Want an easy to use SDR? Here's one.

WILDLIFE BIOACOUSTIC MONITORING
Introducing the robust WTX4 wildlife live-audio surveillance transmitter. The WTX4 acoustic monitoring solution is solar powered & motion activated, it allows for continuous remote data collection and can serve to address questions across temporal and spatial scales.
WILDLIFE AUDIO SURVEILLANCE
Our wildlife series of transmitters provide researchers an unparalleled observational advantage, allowing them a 24/7 live audio surveillance feed from safe distances. This audio is being transmitted from a WTX1 transmitter which was used for a wildlife study in Delta Amacuro, Venezuela. The audio was captured in real-time using an SDR dongle which is capabale of directly recording all incoming audio.HAVE A NON-TRADITIONAL AUDIO SURVEILLANCE APPLICATION?
