We now offer a line of extremely low weight digital ID radio tag products, with weights as low as 0.44g. Each tag contains a unique digital ID, over 4 billion possible, allowing for extremely accurate detection and automated data collection using our base station technology. Our tags provide world-wide option on a single frequency, eliminating issues of your bird flying to flying into different coverage areas. You can track vagrants across the globe.
There are two variants of Radio Tags: LifeTag and PowerTag
LifeTag transmits a unique digital ID every 2 seconds, and requires no battery. LifeTag is designed to last for many years, allowing the researcher to study the entire life of the animal.
LifeTag comes with a variety of attachment options, including rappel harness, leg loop, popsicle stick, and glue on. Also, several coating are available, depending on durability requirements.
With 4 billion combinations of unique identifiers, no two animals will ever have the same identifier. This allows all concurrent radio tag projects to take place worldwide without interference.
PowerTags do not require sunlight to operate. They can be configured to transmit a digital ID as often as every 2 seconds to every 60 seconds, allowing the researcher to optimize between transmission frequency and battery life. Our smallest battery tags have a lifetime of approximately 6 months, while our larger battery tags can operate for years.
PowerTags are globally unique, working in conjunction with LifeTags, allowing for billions of unique tags without any interference between projects.
Base stations automate the data collection in the field. Base stations collect data 24 hours a day, 7 days a week, and can either operate on battery+solar or on AC power for indefinite periods of time. These base stations log the digital ID, signal strength, and time of reception and feature up to 12 different radio channels. These base stations can either store data locally to SD card or transmit data in near real time over cellular networks. Health and status data can also be transmitted over cellular or satellite, notifying staff of any maintenance needs as well as SD card status.
These base stations are weather proof and tamper resistant. They are designed to be deployed for multi-year duration, similar to commercial cell phone towers. They can operate stand alone or participate in large data collection networks, triangulating tag positions in a cooperative fashion.
Nodes are small, low cost, and can be used to provide extremely precise, near GPS level accuracy of our smallest 0.44g tags. Nodes listen on the LifeTag and PowerTag frequency, recording time, signal strength, and digital ID, and transmit to surrounding base stations. By plotting signal strengths across a grid of Nodes, very accurate positioning can be resolved. With high transmission frequency, unheard of near GPS level accurate tracks of very small animals can be collected over many months or years time.
Nodes receivers are sensitive enough to receive signals from animals burrowing underground, in flight, on the ground, and in wetlands and marshes. They are waterproof and designed for long duration deployments. Nodes can also be used for presence and absence detection at a nest box — and can even determine if the bird is inside the box or on top. Think of it as long range RFID.
For field operations and localization of the animal studied, another option is available: the CTT Locator.
We worked hard to revolutionize the way radio tags can be located. Instead of headphones, static, beeps, large antennas, and bulky analog receivers, use your smart phone instead! Beeps have been replaced by unique IDs and precise signal strength in decibel milliwatts.
The CTT Locator allows researchers to enter the field, locate animals, and log the entire session right in their smart phone. The CTT Locator contains a mobile web application that works with nearly every smartphone. Data can be downloaded later, along with position and time of where tags were sighted.
CTT Data Portal
Like our other wildlife GSM products, data can be transmitted directly to our portal — either by cellular, satellite or SD card.
You can view your data, perform complicated analysis, and view base station health and performance.
CTT can also provide data processing for CTT Node products, creating maps and graphs of your study.
