I have the Voyager wireless Bluetooth camera from ASA Electronics. Every time it rains or there is a temperature change condensation forms on the inside and fogs the lens. I talked with the factory but they were no help at all. Their customer service stinks to say the least. I took the camera apart and found a silica gel pack inside. This is what they use inside to help prevent condensation. I dried the camera out with a hair dryer and replaced the silica gel packet then reassembled the camera. It last for a couple of months but now has condensation in it again. The camera should be nitrogen filled but because it has a port for access to the Bluetooth pair button it is not possible because when the plug is removed the inside is not sealed and is exposed to the outside air. The only way to keep condensation from forming on the inside, the camera body must be purged and filled with nitrogen but Voyager did not design for this. For what this camera cost I think Voyager should have done a better job with their design. I would not purchase another.
