Hi I have a lorex NVR with PoE function. A cat 6 cable is running to an outdoor camera and working fine. How can I install another camera close to the existing one please? I mean using the same cat6 cable to connect 2 cameras. Thank you

[@travismcdonnell2894]

@Intermit.Tech I'm confused too due to the fact that I have the NVR system instead of a PoE switch/injector. So, does it make any difference?

[@IntermitTech]

Poh, that really depends what kind of POE it's putting out and on which wires. Easiest would be that x4 POE in and out switch, if it can supply the power, it'll always work basically.

Further to my previous question, I'm currently running a HIKVISION Network Cameras DS-2CD2385G1-I 4K 8MP IP POE Network camera and a HIKVISION NVR DS-7600 Series Model DS-7616NI-K2/16P. I’ve recently tried to run two cameras off one Ethernet cable using a IPCamPower Combiner Splitter Adapter but that didn’t work, they didn’t even get a signal thru them. My question is will the Bellnet network splitter you have mentioned do the job of running a signal down one cable line and allow two cameras to work. I really need to do this as my security system has been in place for a number of years now and I don’t have access to do further wiring in the house. I’ve also tried cheap splitter adapters and they also didn’t work, can you help.

[@adyady3099]

you specified in your video that this works only for 100 base tx cameras. What if i have cameras that say they support both 100/1000 base-t . I know that gigabit can't work with 4 wires but if the camera support both 100 and gigabit , will this still work?

[@waynenocton]

Pretty cool! I just bought a 24 port PoE switch plus the two uplink ports, and I had a heck of a time getting things to work but finally did get it, currently it’s running 6 cameras across one cat6 1gb connection. I never even considered this until I saw a brand new security install that displays 75 cameras on a single 80” television, and it’s on a single 16 port NVR. I’m puzzled how they did it, it’s all plugged into a giant Netgear switch first, and I’m guessing it’s time slicing somehow, or maybe on movement it swaps things, I really have no idea but I’m hoping to get to talk to the techs at some point, as I can’t find a thing on it on KZbin or google, although I really don’t know what to even search for. It’s all a brand new install for a new strip club, apparently lots of cameras are mandatory.

[@IntermitTech]

If we're talking IP cameras you need to fully let go of any 1:1 link that there light have been before with Coaxial based systems or something like that. Even if the NVR only has a single Gigabit port it can still for instance support 50 cameras no problem. It's not about the physical ports anymore but bandwidth (say 8Mbps vs 1000Mbps of gigabit) and processing capability of the NVR.

[@waynenocton]

@@IntermitTech I agree, my first hurdle was only one camera would get an IP from my regular network, but the camera tool took care of that easily once I realized that’s what I needed to do. But the big problem I can’t figure out is, how do you make it display more cameras than the unit has ports? Mine will not let me add a 17th camera even manually, let alone 75.

[@james10739]

So are those adapters just splitting the signals and power is still passing on the same conductors because i have seen using the 4 for standard 100mb non POE connection and then then the other 4 for an additional 10/100 connection but that is not what it sounds like it sounds like all the power is on the same wires and all the data is on the same wires

[@IntermitTech]

That is why it works using mode A, then the power is transferred over the same wires of the data and using the splitter blocks you effectively have 2x100Mbit running over the same cables split in 4 by 4 conductors. No wires get multiplexed that way.

Actually, in my experience, almost everything POE in Mikrotik is Passive 24v based, only their full switches (and those are recommended) offer 48v out in a standard way, but the smaller versions definitely do not. Same goes for UBNT, their full switches do 48v out in the correct way but some smaller devices are only suited for 24v passive (their own equipment). Be careful when buying, although 24v won't fry your equipment, you'll be stuck with something that won't work either.

No, with that device you connect the "in" port to a normal POE powered switch port (100Mbit or Gigabit) and then it can feed 2 100Mbit POE camera's after the Dahua POE Extender. So you only need a single Dahua POE Extender box, it's basically a switch that gets power from POE but then again puts POE on 2 switched output ports again!

[@alinototo]

@@IntermitTech Uhm. Then How would you be able to tell your NVR that here are two camera using two IPs since you will only be using one port on the NVR

[@IntermitTech]

@@alinototo This should work without issue, if you are using an NVR with built-in POE ports, those ports on the back are also just in a switch. Basically you are just uplinking another switch and so more systems can communicate with each other, get an iP and run. Only problem could be that the NVR wouldn't give out more IP's then it has ports for, but I think it gives out a whole subnet range so that won't be an issue either. When doing the active POE extenders though, make sure your NVR can deliver enough power over it's POE ports. These active extenders effectively double or even quadruple the power needed from a single POE port. If your NVR's POE ports only have a budget of 10w per port and that's also what the power supply is calculated towards, you shouldn't use this method but instead use the cable splitter way. That won't put extra load per POE port since it uses 2 ports on both ends.

Actually haven't tried it yet! Image Quality wise I'd say they look about the same now a days and it's interesting if you are upgrading an already coax installed setup. Or even if you are buying complete new it seems it could be cheaper maybe? Also it seems better suited for longer cables runs if you don't have any other infrastructure in place. But for me, I'm into networking and have my whole home (and sites where I install) wired up with networks so running it over that network is the logical choice for me. Maybe in some sort of security business they'd like to seperate it? I don't know. So, it might be cheaper if you are starting from scratch but for me the convenience of using my existing network and using POE can't be beat. :)

hey man, nice videos at all. I got a question about the proxmox machines you built. You are using Samsung 860 evo SSDs right? I often read that the 860 evo (and other consumer SSDs) are dying very fast in proxmox machines. Can you relate to that? Because I want to upgrade my actual server, which isn't running 24/7 and it got only one 2TB WD Red, which isn't very fast :D Later I want to build a cheap machine (maybe working 24/7 then) with a Ryzen 5 2600 CPU and would like to use there SSDs too.

[@IntermitTech]

Next time, just comment on one of the Proxmox videos, or join the Discord! I've had bad experience running Proxmox on USB sticks, even in a ZFS Mirror the sticks basically killed themselves because of the heat and writes (probably). I think it might do some swapping of the KVM VM's to disk causes more IO then you might expect. With that said, 860 EVO's are very respectable SSD's and can handle quite some writes without an issue. Their TLC memory also isn't a problem because it's almost never a sustained load, more random bursts from the VM's. I'll have to check what their wear level is on the machines I'm running that setup on (I have multiple) but I'm not really afraid it's going to be bad. :) Mirror for your system/VM volume is always a good idea. ;)

If it's a HUB and doubles up both 8 connections that won't end well either because pins and data signals will get multiplexed onto all pins where devices don't expect this.

Ugh, this is an ugly hack! Seriously, don't do this people! Pop a baby desktop switch at the far end if you have power there, or a POE passthru switch if you only have a couple of low power cameras. Data is way more sensitive sometimes than you may expect, whilst in traditional CCTV we got away with 4 cameras down a cat5 using baluns, this principle can't be reliably used with data.

[@IntermitTech]

Sorry to hear you say that, I use both ways in several setups and have been using the passive way for years. Both ways are fully within specifications for Ethernet and each connection gets its own dedicated wire, so there really shouldn't be a problem. Using the little boxes also takes out manual error or hacky stripped out cable issues, I've seen people have problems with that because they would use long stretches of non-twisted bare wires. So really interested to hear your experience and what the problems where!

[@cyberprog]

@@IntermitTech it's within spec for 100mbit, but as camera tech moves forward the bandwidth requirements will increase. This is not complaint to 1000-Base-T also which uses all 4 pairs. Using a switch at the far end is more efficient if you need more than 2 cameras in that area also. With converged networks these days, CCTV installers should be doing proper network training! We had some guys out a while back whose proposal included new switches & cabling to areas we already had cabled, and when we tried to talk to them about vlans we got blank looks! Ditto when we started talking about air gapped networks. Not saying all installers are like this, but it's been my experience so far - I've dabbled in CCTV, access control etc. Over the years, mainly because of convergence of IT and building systems.

Alex Threlfall I say Ethernet cable is cheap, run more cables. I’ve wired my house where I have a number if keystones in each room all running to my single 48 port switch. So I don’t need small switches all over my house. If I can run 1 cable to a room, why 4 or 6 cables? Just finished a PoE camera setup. Well done for now with 4 cameras and another 4 planned in a few months. Running Ethernet is generally not hard. I get there are ways to cheat, if you want to call it that. I’d rather be more future proof.

Its not an ugly hack these devices come in handy when a run is complicated and long most Ip systems use 100mbits anyways.

[@jbdragon3295]

Shimon I still think it's more of a hack. Sure it works fine now. But it's not future proof. If you can run 1 cable, it's not much harder to run 1, 2, 3, or more cables at the same time. I know as I wired my house up and ran multi cables to each room to have a number of keystones to plug into and have 1 large central switch. In this case a 48 port switch. Now I've started on my PoE security camera setup and in running more cables. Each camera has their own Ethernet cables and all end up at my new NVR. Yes, they don't use all that much bandwith, but to me still a hack otherwise. If 1 cable fails, you may end up losing 2 camera's. Again, cable is cheap. If you can pull 1 cable, you can just as easily pull 2 or more at once. I pulled a bunch of cables at work for a nice re new Mesh WiFi setup. Now have WiFi throughout the factory including inside the freezers. We have plans to toss the whole analog camera system and install a new PoE system to replace them all and run a bunch more. Again, each camera will have its own cable. It's going to be a whole lot more wiring. It'll require a boom lift to do all the outside cameras. All the walls are brick. Fun, fun!!!

I don't wanna be the wise ass, but you will get interference with the twisted pairs. i switch is the correct way.

[@IntermitTech]

If it's possible, sure. But this method doesn't actually split pairs and running 2x 100Mbit like this has been done quite often in the past, the only difference is that POE is also running over the same data lines. Yes there are 2x2 pairs which are indeed close together but I've never seen a negative effect from it in regards to the connection. In theory there could be more interference, that is true though since it's slightly closer then 2 cables running next to each other each in their own mantle, but I've never known that to interfere either.
