Power over Ethernet CCTV

(
PoE can only exist on the side of the switch, wired with electrically conductive wire. Fiber optic cable can not carry power to anything.

Running copper communications cable between buildings that are not very tightly electrically bonded can create all sorts of trouble. You will want to install some sort of isolation or CAT5 Data Line Lightning and Surge protectors. PoE will not pass through all surge suppressors, carefully read the specifications for your candidate devices.

Here is one of many sources

You use a POE switch with SFP port(s) and IP cameras. SFP ports can take a SFP fiber module to connect a fiber. It can't be tied into existing in use fibers since fibers are point to point, but a new fiber from one of your fiber switches could be run to it.

You're better off to run multiple POE switches less than 100m from each group of cameras than it can reach then trying to extend the ethernet with extenders.

As for monitoring, with a properly setup network you can attach a network DVR anywhere to record the cameras and that DVR can have a TV connected to it to set it up and see the cameras.

I use a 24 port POE switch + 4 x SFP at home, I have a fiber from a SFP port running to a SFP to ethernet converter which then connects to the incoming internet cable. It's so a surge on the internet cable can't damage my networking and computer equipment. It's fairly basic stuff, just get the SFP module that matches your fiber type and speed and hook it up.

Thank you for the replies.

Hello again,
Does anyone know if there is a HD monitor available that can connect to the CCTV network Poe IP switch ( at a secondary location) so the cctv can be viewed at this second location.

Thanks

You should be able to display any single camera with a regular PC and monitor (almost anything should work even a raspberry pi).

It gets a bit trickier if you want to record continuously, and also view the same camera image. Either the camera needs to be able to stream to several users at the same time, or there needs to be a video stream server.

That's a rather broad question. How about monitor size and number of cameras and desire to watch recorded video? At any rate, it won't just be a monitor.

Most network cameras provide a RTSP stream you can view on any capable hardware. Good cameras support multiple streams so you can view them at more than one location.

There are some more consumer oriented pre-built all-in-one DVR devices with monitors that can view a few cameras, but most have a pretty small screen like say 7". An all-in-one PC or tablet PC could be used with the right streaming or DVR software. Often the DVR allows remote viewing and that might be a possibility but I would expect that the live camera viewing experience wouldn't be as good going this route with the trade off being that you could watch historical recorded video at this location.

There are programs like Blue Iris which allows you to view a large number of different IP cam video streams. The monitor is the last thing to worry about

I use a power injector for each of my cameras. My switches are POE capable but I prefer to not use that on outside devices.

The more you know, the more you know you don't know.

If the ethernet cable still goes to the switch then why does it matter where the power source comes from?
