Many state preserves and parks use some kind of tracking system to monitor the habitat and behavior of wildlife and fisheries. Oregon RFID specializes in selling RFID monitoring stations to state parks just for this purpose. These stations also track wildlife inventory, monitoring the reproduction growth of any species that resides in state parks. A basic Oregon RFID monitoring station is made up of a reader, loop antenna, and power source. The company offers several different types of readers and antennas that are designed for long range or proximity range. By having an RFID monitoring station set up in several different areas of a state park or fishery, wildlife can be observed and recorded without anyone being present. Oregon RFID monitoring stations are designed to blend in with natural surroundings without losing the capacity to record tracking information. Once a Half Duplex (HDX) or Full Duplex (FDX) tag is attached to an animal, that tag can then be read by the monitoring station when the animal comes within the antenna's range. Oregon RFID tags comply with ISO standards. The HDX tags are ideal for longer reader distance, whereas the FDX tags are better suited for faster read speeds or when smaller tag sizes are used. As a rule, the larger the tags, the better a read range they possess. Each tag has its own unique number to identify an animal. The passive tags can remain operational for decades so they do not have to be replaced in wildlife.
The antennas of the Oregon RFID long range readers extend up to 30 meters wide, while those of the proximity readers have an internal antenna and also turn off automatically after a few seconds it has been turned on to save on the battery's power. Proximity readers are suitable for close range reading of wildlife activity. The Portable FDX/HDX Reader can be mounted as a USB flash drive, with the files being transferred to a computer for readability. This reader comes with a lithium-polymer battery which can be recharged by a 5 volt USB connection.
The Single Antenna HDX RFID reader can store up to 10 million detection events, and each event record contains the tag ID, the time it was detected and its duration. The reader automatically turns off when the voltage starts to get low and restarts when the normal voltage level returns. The antenna can be situated in a place where wildlife frequents, such as a brook or underpass. When an animal is within range of the antenna, the reader picks up its activities until it leaves the antenna's range. An Antenna Tuning Indicator is available so that you can determine when the tuning is too low or too high. This machine easily plugs in to the pins that are located in the corner of the reader board. Oregon RFID also offers waterproof Personal Digital Assistants (PDA's) which are operators for the long range readers.
Oregon RFID began in 2003 and is based in Portland, Oregon. The company supplies state parks and fisheries across the nation with RFID tracking devices designed to monitor the habitat and behavior of wildlife and to check their population growth. Oregon RFID provides full customer support in addition to documentation on using their products. The company also provides information on synchronizing multiple readers, with both small and large tuning charts. Oregon RFID also has a system diagram on their website to illustrate how it works.
