We purchased four of these inexpensive Loftek IP cameras; one has, apparently sprung a leak:
These are supposed to be fully weatherproof outdoor cameras. They have a one-year warranty from the manufacturer, so this should be an easy replacement under warranty. Still, it involves climbing up on the roof to retrieve, then sending the defective unit back to the manufacturer, etc. All the while, we are down one camera.
I guess this is what can be expected from an inexpensive camera. The units that are still online are working great.
