Ethernet Cable Switch

[Munroast]

I an wanting to be able to switch an Ethernet cable on and off from a timer
Ideally I would like to use a plug in timer. so is there any 240v device that could switch such a cable on and off

Pluged into each other, not sure if that would work for you?

don't really understand what these "Power over Ethernet (PoE) injectors" do , I really just want to make or break the ethernet connection

with a switch like

if I disconnect the power supply to it, does all data stop ?

I can find an on/off switch but not timed...

If it's to stop kids, being able to browse, between certain times - Most routers, include that facility.

You could buy a cheap Ethernet switch and plug the cable through this and then put the ac adaptor for the switch on a timer.

that is exactly what i am wanting to do, so if you switch the power supply off to the switch (that to me just looks like a connector) then the data stops flowing ?

these switches (which i have never used) look like they join 5 cables into one, I was wondering if it is simply joining two cables if the data would flow without power ?

If it's to stop kids, being able to browse, between certain times - Most routers, include that facility.

nothing to do with that - this is a camera system that plugs into the router, i need to disconnect the camera system from the internet during certain times

Yeah, any cheapo ethernet switch, with as few ports as you can get, e.g. 4 or 5; just connect to any two of the ports and switch the power with a timeeswitch.

Do you still want the camera to work and record images onto eg an on site DVR even though it's not on the net?

If no, and the camera gets its power from the Ethernet cable via a poe injector, then sure just put one of those rotary dial timers where you push plastic segments in/out in between the mains and the injector - no power to injector, no data flow. It will turn the camera off though

what these "Power over Ethernet (PoE) injectors" do , I really just want to make or break the ethernet connection

Most consumer grade devices can't add power to an ethernet cable, but it's common for commercial grade devices to use the standard so that a device that is capable of "power over ethernet" (like your camera)can run using just one cable (the same cable that does the networking, does the power-a bit like your smart phone- the data sync cable to the computer can also charge it).
You hence have these little blocks called injectors where you connect a data cable to your basic BT Internet router (which doesn't do power over ethernet) and then you connect another cable to your camera and it's the injector's job to pass the data through unaltered but add power going out to the camera.

If you want to carry on recording but not have the footage net accessible for a period that involves some more smart solution , probably software

 

[SithLordHood]

Just buy one of these (or similar):
Netgear GS308 Ethernet Switch

Then put the ethernet csble 'through' it, any 2 ports will work.
When unpowered there wont be a connection between the two cables, when powered there will.
Put the AC power for the GS308 through your favourite timer switch, either manual or a smart one.

 

[robinbanks]

But that might be totally unnecessary expenditure if the OP has a PoE injector that can be powered off by the same timer you propose using for your switch..

I have a "Smart Switch" that I can control through python from the server, and I will get a loan of a powered ethernet switch from someone. I am fairly certain now that it will do what I want

I don't really know what these ethernet switches do, they seem to have a port on one side and 5 ports on the other ?
I had wondered if the power supply to it was some sort of booster that may not be needed if I was only connecting two wires

So… are your cameras powered using power-over-ethernet, or not?

havnt got the foggiest,presumably the eight camera are all powered by the box with the recorder in it - this is not to be switched off and needs to keep on recording

I want to interrupt the Ethernet cable that goes from the recorder to the router. I know that pulling this stops the internet feed

OK. Assuming that there is no way to configure either the recorder or the router to disable on a time schedule, then as above, connect it via any ethernet switch and put a timeswitch in its mains supply. When no power is connected, nothing goes through. There are some suitable switches on ebay for not much more than a tenner (e.g. TP-Link, Netgear). Make sure it says “gigabit”, not “fast ethernet”.
