Environet | Biotelemetry Autonomous and Real-Time Database (BARD) |
|---|---|
Detection times stamped by node GPS (m/d/y hh:mm) | Detection times stamped by receivers (m/d/y hh:mm:ss:ms) |
If offline, all detections are stamped with time of next successful polling | If offline, all detections get original time stamp from receiver at time of detection |
Polling limited to minute polling rate due to cellular node time stamping | Greater temporal resolution, since time is independent of cellular node |
Netronix server space limited | SQL space permits 4 tBytes; “unlimited” space with Amazon cloud |
Limited to 20 detections per minute | Unlimited detections per polling interval; 196 kByte limit, which equals about 2000 detections per polling |
Web interface not adaptable | Web interface with SQL database is adaptable to visualize any query |
Displays single monitor location | Displays multiple locations for comparison |
Unable to input a list of unique IDs | Can provide list of specific IDs |
Current database, 101 gBytes with 52.7 million detections |
