Spec says it uses 70w at idle, unless you really need all those ports its costs you $175 a year just to run that switch at California rates.
24 port switch, unmanaged for cameras only 300w / who has the best? budget 300.00

Spec says it uses 70w at idle, unless you really need all those ports its costs you $175 a year just to run that switch at California rates.
Just wanted to add: this is not an exaggeration at all, and if you are using enough electricity to be bumped into "Tier 2" rates (most people do, for at least some of their usage), it could be up to $240 per year, just having this switch plugged in (not counting cameras).
I don't mind paying the electricity bill for devices that are doing real "work" for me like the cameras and BI computer, but wasted idle usage of that magnitude is unacceptable in my book.
Electricity is always a major consideration, especially in California. I'm still on NEM1 for a few more years. And with a medical baseline, I get an extra 500 kWh under Tier 1. Our home uses about 1300-1600 kWh per month, and that's including charging a Tesla. We have about 4 kW of solar on the roof.
My Hikvision NVR with only 16 ports, uses about 40 watts. I've already got two big switches, as every room in the house has CAT6. Right now I have 16 cameras. I plan on adding at least 4 more cameras - a couple more general view cams and an overview cam pointed towards the street with a LPR cam. The Cisco switch has 12 ports up to 30W, and 24 ports up to 15.4W. So this Cisco switch will use 35W more than my NVR does now. That's about $120 more per year than I'm paying now, but I'd have more capacity as well. Cameras need power. Either I run power to them at the installation site or I use a PoE switch.
I have to take back my comments on the switches from the last couple days.......looks like one of my nvr's is no longer illuminating the Link light for Gigabit on my Cisco GIgabit POE....
Amcrest 4108e HS only shows 10/100 link light....but the older Amcrest XVR is showing a 1Gig link light. swapped cables to confirm....swapped ports....swapped switches....
somethings wrong with its gigabit link
so all my results could be skewed......

All right so i linked/moved 2 IP cameras over to the Xvr to relieve pressure on the slower link NVR. now hopefully the web interface for the NVR will load a Camera GUI in a decent amount of time.
I think the spec sheet for that nvr shows you only have a 10/100 nic, so don't chase a phantom thinking you can push 1gig through that port.
If you want a bit of help on your switch /camera deployment draw a sketch on how each cable is connected and what it's for.

It may sound like a monster as well.
It's going into my media closet that's sound isolated with door seals and everything else that goes with sound isolation. Also, most times you can replace a noisy fan with something less noisy. I do this on my QSC PA amps that I use as subwoofer amps.

You can also quieten the fan by simply putting a resistor inline with the positive supply to the fan. For these high end enterprise switches this isn’t the best or proper way as they use fan speed sense but it’s enough to reduce the top end whine of the fan so that you can no longer hear it unless within a few feet.
Looks like there is a good choice for unmanaged switches made for cameras and maybe a phone or two. Everything is made in China now days with much of the same SOC and power supplies.
I have a couple of recommendations.
First, the Brocade ICX series switches are very good. I think the ICX6450 24 port POE model would be an excellent option for you. Check out this thread on "Serve the Home" for more information than you could ever want regarding these switches. Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)
I run several Aruba S2500 POE switches myself. I bought them before that Brocade thread was started. Here is a thread on the Aruba switches. Aruba MAS series SFP+ & POE+ switches sub-$100
