While your waiting for your switch, lets talk about cameras, you are choosing ...
I have used several of these and while they are OK cameras I'd like to suggest a different camera that I'm sure you will find you like better..
Yes I know these are only 1.3mp, believe me in this type of application being a high mega pixel camera does have a advantage but in reality it's not even close to a necessity, or even in some cases wanted because of the size of the image files that they create when a event is captured.
The reason I recommend the Trendnet cameras is quality, I have a mix of Hikvision and Trendnet cameras and while they look identical and mostly configure exactly the same other than firmware and camera interface differences, there is a difference in quality. The cameras as I said look the same on the exterior and are probably built in the same Chinese factory, but internally they are different, while the Trendnet are basically bullet proof, some of the Hikvision produce artifacts in the feed, it's momentary and doesn't trigger a event but it's obvious that they are not the same level of quality.
Having said that I have two Hikvision cameras that do not have this issue, but I have to of the EXIR cameras that one has the issue the other does not, EXIR is a great thing, the cameras are physically bigger than normal bullet cams but the IR range is greatly extended. I use one EXIR mounted high on the side of a building to illuminate a 40'x150' area and at night it is like daytime viewing that feed, but that camera about every 1-2min will create artifacts in the monitoring feed and like I said it doesn't create a event (motion detect) but is really annoying because it grabs your attention. The odd thing is it will do this for several hours then go maybe 4-6 hrs before doing it again.
Here's what a EXIR looks like..
So when considering cameras along with placement to capture the FOV (field of view) that you want, you need to also consider the depth of field, a good example is that I have a camera on a driveway that is about 160' long at the end of that 160' is a camera, the monitored image covers the entire drive very clearly but the motion detect will only trigger if the vehicle or person is around the 60-80' distance from the camera which requires another camera in a closer location to capture all the way out (if you need that coverage). Luckily for me this drive has three other cameras that also cover various aspects of it that trigger all the way out to the sidewalk....lol
Hopefully you find some of this info of use, we can talk cameras and camera placement for days, but a good site plan even if it is in your head is better than just throwing up cameras and finding out later (after wire is run and camera is mounted) that you have blind spots, re-positing cameras is one thing but needing a 2nd camera to cover a given area is sometimes the case, I'd highly recommend temporary camera mounting to get a idea of field of view before doing the finished installation.
Oh one other thing.....DO NOT even consider cheap IP POE cameras from China that you will see on the net for cheap cheap prices, they are junk, I have tried several and if they work at all their lifespan is very short, I have a dome cam in a building that was given to me that configures very easily but freezes, the IR has about a 4' distance, the colors suck and the camera won't refresh 90% of the time after a event is triggered.....just pure junk!
Take a look here to see what I mean...
Another thing is you will see the term ONVIF, this is a open standard that IP security devices should comply with, it is a good thing if a camera is ONVIF compliant and in the case of some monitoring software is a requirement to even configure the stream, ONVIF is highly touted in the cheap cameras and higher quality cameras don't even mention it except in the features..
While I'm writing a wall of text........ nothing wireless either!
