In my experience pretty much all IP cameras phone home in some way at some point, so yeah, you are best off putting them on a separate VLAN and routing appropriately.

The only brand I’ve had a good experience with is Reolink. I don’t think the quality is appreciably different than a brand like Hikvision and the firmware and support is vastly superior.

Edit: Some good info on using Reolink cameras with Frigate. I use Blue Iris but would vastly prefer OSS.

This sounds excessive, that’s almost 1.1$/day, amounting to more than 2kWh/24hrs, ie ~80W/hr? You will need to invest in a TDP friendly build. I’m running a AMD APU (known for shitty idle consumption) with Raid 5 and still hover less than 40W/h.

This isn’t speculation on my part, I measured the consumption with a Kill-a-watt. It’s an 11 year old PC with 4 hard drives and multiple fans because it’s in a hot environment and hard drive usage is significant because it’s running security camera software in a virtual machine. Host OS is Linux MInt. It averages right around 110w. I’m fully aware that’s very high relative to something purpose built.

Right, and spend even more money.

Residential electricity isn’t cheap

This is a point many folks don’t take into account. My average per Kwh cost right now is $0.41 (yes, California, yay). So it costs me almost $400 per year just to have some older hardware running 24x7
