@rogere_821547895865564 Geez. Looks like you need to format USB stick with NTFS file system. Looks like I am starting to get the hang of it. Very painful learning curve. I will keep pounding away on it.

I have the RLN36 and Duo3 camera running now. I would like to export some recorded video. I inserted formatted USB thumb drive and have tried all the NVR functions but all fail with 'not enough space' error. I am suspicious that this is impossible to do. It looks like I will need to get rid of the system unless I hear from support this is possible. Too bad. All was going pretty well except what good is the system if you cannot export any data?

@rogere_821547895865564 : Manual or not, I put in my order for the products and will see how well they work for my application. Over and out.

@rogere_821547895865564: I tried chat support to find the manual but gave up trying to find the manual specific to the RLN36. I don't think one exists.

@joseph_1979: Thank you for reply. The manual you reference helped a little bit but I am not sure how much described operation applies to the RLN36. I get the impression the RLN36 has a few differences in client/web/FTP operation and also has the hardwired alarm in/out connections. I will seek the RLN36 manual as you suggest. Roger

Before I shell out for RLN36 and Reolink Duo 3 Poe it would be nice to get a sanity check on how I want the system to work. My plan is to setup the Duo camera to record vehicles passing by. When an external alarm input trigger is applied to the RLN36, I would like the RLN36 to record pre and post alarm event maybe 30 seconds. Ideally this segment of video would be automatically saved to the hard drive as a discrete video file identified with a date/time file name. Does all or part of this scheme appear reasonable?

If the individual event file saving is not possible, are alarm event videos somehow exportable individually or as a 'class' or group? The I would need to break out each event separately somehow.

It does not sound like there is an API to control the RLN36. This would seem to be ideal for my application as my experience is as programmer. I am new to the Home automation topic. Does the RLN36 integrate with popular home assistants so I could manually control the above operation?

Thank you for sharing thoughts and experiences on my proposed system.
