I’m a milestone dealer so I’m running essentials which is free up to 8 camera channels at my house. Enterprise VMS is the only place I would go other than open source options just because any of these cloud connected retail options can SAAS your shit up at the drop of a hat.
I should spend the time to figure out zoneminder just because the windows server I have is a reject proliant and takes too much wattage for what it’s doing.
