I was very happy with Vultr, but they weren’t happy with my Linux isos.
Using linode now, the backup system is more expensive and the emulated terminals don’t seem as nice as I remember vultr but I’m still very happy with it, especially for the price.
Be aware that some Reolink cameras (B800 for certain) require a reolink DVR. The alternative is neolink, a program that reverse engineers the protocol.
I agree, just be careful with the caulk- sometimes you end up sealing liquid (or vapor) water IN instead of out. If you have good overhangs it’s probably fine but don’t do this below a window or other opening.
And for anyone wondering about concrete wicking water, look up ‘capillary break’
