We have begun to install these cameras and find that they tend to be hard to charge. My two main questions at this point are: How much current is needed to trigger charging? Is there a firmware restriction to temperature range before they can be charged? It seems that the unit will not charge at 18 degrees F.
I don't know the details as some has said but they do not charge below 32F to protect the battery. The cam will still work just not charge. If I read that wrong someone correct me as do not have any cams connected to AC. I have one on solar panel and assume that is the same but have not been through a winter with that yet.
Was hoping for a better solution for cold Canadian winters but may just change the profile the cam uses during winter to minimize the trips out back to grab the camera. I use the cam mainly to ensure my doggo is not getting into trouble. 😉
