That is a camera that is well respected here because of it's good low-light performance. These are 2 megapixel cameras, which is standard 1080P.
There are starting to be 4 megapixel cams with allegedly decent low-light performance, but I have not tried them.
The restriction to have the cameras be supplied with black finish is another thing that limits your choices. If you're willing to use white cams, or to paint them yourself, that opens things up further for you.
But yes, those black ones in your link are excellent. Being able to adjust the focal length after installation is handy, and they do perform very well. They're one of the most highly-recommended cameras on this forum, for sure.
There's still quite a bit else to all of this.
First, how will these be mounted? I use the PFA-122 junction boxes to mount those cameras. These junction boxes make things easy, but I'm not sure if they are available in black. So you may have to paint them if black is a requirement.
Second, for running
Blue Iris, you want to use a dedicated PC that is used only for Blue Iris. You want it to have a fairly recent Intel processor that has their quick-synch video processing built in.
@fenderman has excellent recommendations for refurbished PCs that will do what is needed. That's the best route. I have gotten six PCs he's recommended, and they've been excellent for Blue Iris and other uses.
He maintains a section on BI hardware in the
Wiki. Very useful!
You will also need a good POE switch to power and connect the cameras, and there is a thread for choosing those here that is updated regularly.
Finally, to secure your system, many of us use newer Asus routers that have built-in support for, and powerful enough processing to run a VPN so that you can block all of these cameras from directly accessing the internet, yet be able to connect to your system remotely in a secure way.
There's a bit to all of this, and it is worth taking the time to read about all of it to get things set up properly. There are a lot of possibilities, and it is a lot digest, but worthwhile to understand in the long run.
Get good pure-copper Cat 6 cable, and run spares to each location or area.
You'll probably end up wanting more cameras than you think you will. Run wire everywhere. Get a bigger switch than you think you'll want, etc.
As much as it's a pain, really do try to read and absorb as much as you can before choosing your equipment and planning everything. There are some
tools available to help plan camera locations and coverage so you can select the cameras and focal lengths you'll want.
But if you don't mind adding to the system a little at a time, you can start off with a few general coverage cameras and then add in tighter or more coverage as you find needs.
There's so much to discuss and decide. Try to take your time if you can.
