Running Power to Cameras

I have several long runs from our DVR to cameras. I don't really want to do home runs for all of them.

I was thinking of using a home run to a POE switch that branches off to 3-4 cameras.

This works great on the benchtest, however I ran into a problem. There is no power near where I want to put the POE Switch. Is there another solution where I have some type of POE injector that will power the POE Switch so the switch can sit in the ceiling with no access to power, other than a Cat5 cable?

He's asking for 3-4 cams on one ethernet run.
The first one you linked will only do POE on ports 1 & 2.
The 2nd one is only 2 port, but on the same product page has the same 4 port I already linked above (my 3rd link).

I too, have not used any of these.

No, the power and network goes over the same line, that's how POE works. These are then splitting the POE power to the 4 ports.

You wouldn't want to power 4 PTZ cams off these, unless you used the 3rd one, and it would need a 60w injector to power it, as a regular POE switch outputs either 15w or 30w per port.

I don't actually have PTZ, just regular Hikvision bullet cameras. I know our DVR has POE built in. I suspect I would still need to inject even more power into these inline somehow?

I have no idea what DVR you have, so I'd only be guessing. You need to looks up the specs on what it outputs per port.

Here used to utilize Tycon mid span injectors....many many years ago...100Mbs sized...

Original CCTV configuration was house out and edges of property in. Each camera saw other cameras...

I used irrigation PVC and asked the sprinker installers how to use their machine, gave them a $100 to install multiple PVC chases from the house to the perferal edges of the property...
