Hi@sumanthp, this is really a genius product and hunting.
The sun is free and has it in unlimited quantities and the transfer to us is continuous.
This device works only when it is needed and that is what is most important for each job, since productivity is the highest
(no idle).
When is nothing happens Solar Cam sleeps.
The electricity is resting in the battery.
Solar Cam does not make meaningless video.
But he sleeps with one eye open.
During sleep the passive infrared sensor is always awake and follows the change of the ambient temperature within its visual field.
When the change occurs within, just half a second, the Solar Cam is awake and shoots an HD video event.

Perfect work.

Good luck with the hunt.
