RanaVision

To date, Rana has been used a number of projects looking eusocial hymenoptera including studies of bumblebee and hornet activity in the vicinity of their nests[1] and of the behaviour of hover flies and other pollinators at flowers[2][3] and as a general purpose e-ecology tool for the automated remote observation of plant-pollinator interactions in the field.

This offers a relatively good real time performance on the relatively slow Atom N450 processor which was chosen to keep power consumption low (so the logger can operate stand-alone with solar panels in remote field locations).

The data logger is connected to the outside world via 100 Mbit/second Ethernet (Wi-Fi and a mobile phone dongle could be substituted in remote field locations).

Subsequently, Rana has been ported onto a number of low power ARM based devices such as the Raspberry Pi and Odroid [C1] and [C2] which can be operated off the grid in remote field locations.

In addition, it has also been used with near infra-red night vision cameras to monitor the activities of nocturnal invertebrates including cockroaches, moths and bed bugs.
