Here we have an example placement of elephant-detection devices. This would be case-by-case, based on the routes (as shown in green) that local people suspect the elephants are using to launch their crop-eating raids! The devices can be moved as the elephants change their tactics. The devices would also be placed along the established elephant paths (e.g. to watering holes, as shown in red).

The purpose of detecting elephants along their established paths is to warn local people of their presence, so humans can avoid the area when elephants are moving!

Here we have an example of placement of the elephant deterrence devices: these play the sounds of bees or tigers in order to scare the elephants before they cross the interface between forest and farmland. These deterrence devices are triggered by a positive sighting of an elephant by a detection device.

Prior to installation of the elephant detection devices, and deterrence devices, we could conduct a surveillance survey (e.g. 10 days), using aerostats with Ultra HD video, in order to acquire accurate data regarding elephant movement.
