Jen-
I had to put a new cam in out there because the old one died over the summer. They do not make the one I was previously using any more and I do not feel comfortable putting a really expensive camera out there when it could be stolen. The cam I replaced it with is suppose to have the same resolution as the one it replaced and to me it looks about the same. I think the sign is futher away this season than last, at least it looks that way to me when I look at the pics from last season. Note that the archived images from last season from "Michael O" are ones that they took with their own digital cam and not one from the trail cam. The image from Ken R is from the trail cam and shows the sign a lot closer than it is this year, with all other objects looking about the same clarity.
As for the updating, several things can cause a problem. First, the computer it is on will just crash and needs a rebooting. I think that is what the current problem is and with your Dad being sick I did not want to bother your mom with the cam issues. I wish I could get down there to reboot it when this happens, but live 45 minutes (in good weather) away and just cannot get down there at the drop of a hat. This is not a new issue or something that is happening more frequently, it was just addressed quicker last season when you mom and dad had more time to get to it.
Another issue is I am now using the wireless network they have at the cabins and we still need to move the hub closer to the front window to get a stronger signal to the cam. Something I was going to do when I came down to help with the other cam they wanted to put up.
The other issue is just a software hang up that happens. It is a simple fix now that I have remote control software out there and do fix the cam that way several times a week. However, when the computer is not available over the net (like it is now), I cannot control it.
So right now it just needs a simple restart or reboot. The key for the box housing the computer is sitting behind the front desk at the cabins, feel free to reboot now and any other time you see it down for more than 24 hours.
As for the clarity, other than popping for a more expensive camera and risking having it stolen, I really do not know what can be done.
