I am just building up my house Wi-Fi with TP-Link Mesh Deco XE-74, and I am also actively looking for an PoE Outdoor Camera to be able to store videos on my custom SBM server. I have a raspberry with many functions. 1) It has a fine DAC, so I play music from Laptops and Phones via AirPlay over the network, then convert it to analogue audio and send it to my old analogue audio gear. 2) Have a home file server installed with USB3 attached hard disks through SMB server over Linux OS. 

So for the SMB file server, it would be great to have an outdoor camera supporting SMB. In this way, I will have the possibility to add SSD storage without limits :)

Also opening the video files from any device from the local network accessing the file server.

It would be great to have support for FTP/SFTP, as well as the ability to send photos or recordings to the phone upon motion detection. Currently, recordings can only be saved while being on the same network, which is quite absurd. I have a cheap bulb camera that can do this without any issues. I was planning to purchase more cameras, but I will have to choose another manufacturer if these features are not available. I have Tapo C325WB

I would like to save the files from my C200 on my NAS.

Saving to SD card has numerous problems:

1. many on this thread already mentioned it, but stolen camera = no footage.

2. storage management. Need to regularly manually clean out the SD card.

3. You mention that to capture camera feeds to the NAS, we should use software such as iSpy.

The problem with that is that it requires a powerful server to perform image processing, especially when multiple cameras are involved...

Processing that the camera itself is already capable of.

I only want footage when camera detects motion to be saved, not 24/7 footage.

And for the camera to log into my NAS and drop the file off at a designated location via SMB.

Operations that are scalable to many cameras with a weak cpu but high storage capacity server and is low burden for the camera itself... just a simple file copy from SD card to SMB location.

4. Alternatively, open up the SD card storage to the LAN, so that the NAS may poll the camera storage and fetch any new files from the camera (i.e. by running rsync via cron every 30 sec or so). Not as desirable as camera being the SMB client, but better than what we have right now, since rsync will be way cheaper (in CPU power) than performing 24/7 image decoding and motion detection on multiple video streams to determine what to save and what not to save.
