Never heard from the support folks, but this behavior hasn't happened in weeks, so maybe just glitches.

Im assuming your laptop is a Mac. If so, then the ios app formatted it for Mac. Mine, a 410, works fine and I never did a thing with formatting it, assuming the camera would. I took it out of an old mp3 player so it was probably fat32 going in.
Do you see an option in the camera for formatting the card?

My rlc-410 is programmed to put captured motion events on my Synology NAS, and each camera that I have has its own folder. This 410 is pointed to the folder "Outdoor". In this folder it creates year, month and day folders on its own, but more days that not it also creates a folder Outdoor. I thought, maybe since, say, the day "28" doesn't have the Outdoor folder, it creates one, but it doesn't put the videos into it, just in the "28" folder. Can I stop it from creating unnecessary folders?

That is the way I had it, only detect and record motion between 6pm and 6 am, but was still getting detects all day. Adjusting daytime sensitivity to lowest has eliminated them.
I use this camera to monitor wildlife visiting our yard, but also get lots of video of falling or swirling snow.

Maybe I'm not understanding. Are you getting detection videos sent to your NAS in realtime now? If so, why then copy the same thing from the sd card?

Thanks for that tip. As of the time that I disabled FTP for the daylight period, along with the desensitizing, the videos have stopped. You may have answered this question.

I only want this camera to react to motion during night hours, and it's set as that now, but all day it creates stills and videos to memory. Is there some other settings?

I don't know Cerberus, but in my Synology NAS its a matter of setting permissions and creating a folder. The path to that folder has to be input to camera settings.

I have my new 410 doing this. It FTPs the detections, both video and stills, to my Synology NAS. I can then use the Synology app to access this over WAN, or simply as a shared folder over LAN. I manually remove files from NAS over time.
