I suppose with extended vertical FOV you should be able to see packages better that are typically place below the doorbell.

a NAS having a CPU almost always means that it requires a fan so that the device does not overheat. There are a few 'fanless' NAS solutions but they either are very small or use some alternative cooling - say hydro-cooling or gas-cooling (both are more typical to full-blown servers). I would not recommend any fansless NAS, just not worth it!

That won't be waterproof would it?

Yeah, synology is a beauty compared to hikvision's beast

Isn't blue iris just video management soft? I don't think it can affect the quality of recording can it?

It is typically a greenish terminal for Hikvision. Other brands may have other colours but they otherwise look the same.

I think that's because synology makes it a bit more difficult to process and adjust for the rotation, so it basically flips the picture - so, say, if you have 2560 x 1600 resolution, when you use the corridor mode it just flips it to 1600 x 2560. I think the best thing in that case would be to physically rotate the lens if your camera allows for it!

Tnks for your help with this!

I am not sure i can make heads or tails of this ... are you building a burglar alarm powered by a separate power supply, independent of your main power supply?

This is a very fair point!!!!!! NB! From personal experience, if you use a Hikvision camera, it may actually be easier to just use the sticker for size reference and then use the actual bracket and a pencil to indicate where to drill the holes. I've just had a pleasure of trying to mount a Hikivsion junction box.... I am sure it would have been fine, if i had say a few more hands. I wonder if Hikvision engineers ever tried to use the template themselves??? The ring/plate pretty much completely obscures the holes for the misc wire and cat bundle. I thought the sticker template was really handy but it turned out to be for a different model (question mark) and no picture of where the mounting holes actually are. Anyway, i just ended up pre-guessing where the holes should be and ignored the emplate althogether!

Is it this one?

This is just a great post! It's just a shame that I did not find... like 2 days ago, when I was trying to figure out how to get my cameras configured. The 'Easy Quick Start' guide that came with the cameras was neither easy... nor quick! I was actually looking how to get mic connected (which you guys very nicely covered in your other post) but this guide is a jewel!

Am I right that if I have a camera with an in-built mic, then I don't need any of the above? Also, if my Hik camera doesn't have the -S suffix at the end, does it mean that I cannot have any audio there at all? Cheers
