One thing that springs to mind is a monitor for predator (pest animal) traps in remote bush regions. The system spends most of its time asleep, and is woken and starts consuming power only when a PIR sensor is triggered from a visiting animal's body heat.
Then the battery-sapping stuff happens to analyse video and differentiate between target and non-target species and finally trigger the trap or go back to sleep.
A system like this would be an ecological game changer in my country.
