I'm not about to go to nest, or subscribe to a cloud host service so no worries there, all footage will be stored on side on a HD.I personally wouldn't touch a Nest system for either CCTV or heating, it is a dataminers dream.
Make sure the camera's are at least 960, as to having them covert complete waste of time the whole point is to move the scum down the road. They will see them anyway at night as the IR lights will be on so don't paint them black if you must paint then paint then red or yellow.
We currently have rc wired cameras but I'm moving over to IP with a Synology NAS powering them from a POE switch. The cameras are only £30 each & amazing quality.
I'm of the thought that security should generally be discreetly engineered in, i.e good doors, frames and locks, no hidden corners to allow thieves to work unnoticed etc. My theory is that nothing screams 'PROPERTY FULL OF VALUABLES' more than visible alarms, CCTV and multiple door locks. Security can always be defeated, but why attract their attention in the first place? I could be wrong.
Please can you convert the 'bolded text' bit of that into English for me?
