Blink not working at night. Blue light on with loud clicking noise

The camera works fine during the day but at night it stops working. The blue recording light will flash and the camera makes clicking noises. Is it condensation, lack of power, or something else? Anyone else have this issue?

Common issue, reported many times in the forum, almost always requires new batteries. Has happened to me on more than one occasion.

Do not take any notice of the battery indicator in the app. It is notoriously inaccurate.
