Hello friends and Good Day, this is Fred with Tech Talk. We are coming at you today with a
video on what to do in the event that you have plugged in a network IP camera to your LAN using
a PoE switch and you are unable to locate its IP address. You can't find the camera on the network.
We have a previous video on the Advanced IP Scanning Tool and from that video we received
a couple of comments. I am going to put one up right now from Cody. In a nutshell, this says "hey
you know I followed your video and did what you said and I'm still unable to locate my IP cameras
on the network please help". OK this can occur because of a couple of factors. The most common is
these cameras, when they are shipped from the manufacturer, most of them are shipped with a
static IP address. OK, what that means is the IP address is pre-co pre-configured in the camera.
With Hikvision that IP address is 192.168.1.64 and when this plugs into your network it can only be
located at that IP address. Most network devices with modern technology, when you plug them in,
they are in what's called DHCP mode and they allow the router or the routing device in your network
to give it an IP address. Most of these cameras won't, so you'll have to log into them manually
and put them into DHCP mode which will allow them to communicate with your network.
It's not a difficult process we're going to cover it right now
Alright, let's get into the meat and potatoes! Before we do, you know the drill! There is a
subscribe button in the bottom right hand corner of the screen. Please subscribe to our channel if
you have not already done so, that way you'll be notified when we post future content. Also
like the video if it's useful to you and leave comments again this video is based on Cody's
comment. We're not going to get into an advanced networking class today, but it is important to
understand how a routing process works in a home or small business. Okay you will have a modem
from your internet service provider some modems are modems slash routers those will give you wi-fi
directly from the internet service providers modem when i say internet service provider isp
i'm referring to you know verizon comcast atlantic broadband cox all of those guys those are internet
service providers so they'll come into your home and they'll hook up a modem okay and that modem um
will either have a built-in router or oftentimes it will be hooked to your own router okay
a lot of people have linksys netgear router stuff like that plugged into your modem and the clients
in your home connect to this router okay they're not connecting to the modem from the isp okay so
these all we're gonna put it up on a screen right now and hopefully it makes sense to you
but but these routers and again we're talking about linksys netgear asus they all have a a
default ip address which is also referred to as a gateway most of these today are 192.168.1.1.
You'll see that where it says router's LAN IP address. That's the private network. When
a device connects to this router, you'll see computer one, computer two those computers are
in DHCP mode and the router will give them an IP address. Everything on your network communicating
to your router needs an IP address. Computer 1 its address is 192.168.1.100 and computer
two (that's the second device to connect to the router) the router has given that 192.168.1.101.
okay beautiful so that they can communicate with the router they're live on the internet.
What we see here is the security camera. If it is shipped in DHCP, which again most of them are not,
the camera will do the same things as the previous two computers. It will allow the router
to issue it the next sequential IP address which most likely would be 192.168.1.102.
so if the camera's in DHCP, that's what will happen. But what if it was shipped
in static mode (which most of them are). We have already discussed Hikvision, when
that hardware comes shipped from the manufacturer it's going to be shipped at 192.168.1.64.
Okay that would work with a Netgear or Linksys router. That should work it doesn't matter that
it's in static IP because that IP address matches the gateway of your router. Same is true with
Dahua. Okay, Dahua comes shipped 192.168.1.108. That is also going to be on the same gateway
so in this scenario we will have no problem locating the camera using Advanced IP Scanner.
We run into problems is in the next scenario. Yes, on this slide we see where we get ourselves
into a conflict. In this situation we are using the internet service providers modem
which has a built-in router. It is giving us a LAN with an IP gateway of 10.1.10.1.
okay we'll refer to that as the gateway. You will see these two computers,
they are as most computers in DHCP mode, so when we plug them into that 10.1.10.1 gateway
they take on those addresses right. 10.1.10.2 is computer 1. 10.1 10.3 is the second computer.
But look at our security camera, that's where we have a problem. It came shipped again with that
static IP address of 192.168.1.64 and it cannot communicate with the LAN, which is 10.1.10.1. To
make the communication work, and to make this camera discoverable using advanced ip scanner
tool or our Onvif scanning tool, we need to get that camera out of static mode and into DHCP
mode. Reboot the camera and when it reboots it will take on the 10.1.10.1 gateway
of our comcast modem. So thats what we're going to do. We are going to do this real time. I have
a camera that is in factory default mode okay it's just been shipped it hasn't been networked
we're going to plug it into our network. I know my LAN gateway is 192.168.0.1 and I know this camera,
because it's a Dahua camera it has been shipped with 192.168.1.108 as its static ip. When I try to
pull it up using a scanning tool, I'm not going to find it. It's not live yet, so I'm going to
show you how to find it. I'm going to show you how to switch it to DHCP and how to use those
scanning tools. So let's get into it. Alright, so we have opened our ONVIF device manager,
which is a discovery tool for onvif compliant devices. As you can see, the camera is not showing
up. It is not being located on our system just like it would not be located with the advanced
ip scanner. We have already identified the root cause of this. The camera is on a different
gateway than our computer. Okay, our computer is in DHCP, it's getting the 192.168.0.1 gateway from
our router, and we know the camera is at the ip address 192.168.1.108. We need those gateways
to match in order to communicate with the camera and put it in DHCP mode to reboot it
and to have it be assigned a favorable ip address from our router. The first thing you're going
to want to do is find the ip address of your gateway. To do that you simply hit the search
button and you're going to type cmd. You will see an option for command prompt. Next type ipconfig.
Hit enter. It will tell you what your gateway is, just like i told you it's 192.168.01.
We know the camera is at 192.168.1.108. Because it's not the same gateway, there's a broken link.
This will also tell you what your device, your client is. In this case a laptop. The
IPV4 address that it has from your router is 0.16. Okay with that said we know we need to
change our gateway. To do that what we're going to do is we're going to hit the windows button on
your keyboard and the letter X just like so. Now you are going to click on network connections.
This next step will depend on if you are hardwired or connected to wi-fi. okay. As you see we are on
wi-fi here, we're going to have to hit wi-fi and go into our properties. If you are hard wired,
you'll go into ethernet properties and you're going to have to change your IP assignment from
DHCP to static. We want to click manual. Turn on ipv4 and just type 192.168.1.9.
Our subnet 255.255.255.0. Just like so. We are changing our gateway from .0
to .1, which is consistent with the camera. Therefore, once we do this,
we will be able to pick it up with that discovery tool. So let's hit save and see what we have.
Alright so let's go back into our onvif device manager
Low and behold look here friends! We have found our camera 192.168.1.108.
So we will be able to log into the camera at that IP address
using any browser and we'll change the networking mode of the camera from static to dhcp.
So let's go ahead and open that up in a browser. Because this is the first time the camera has been
logged into, it will ask us to activate the camera and come up with the administrative password. So
you're going to have to come up with a 8 to 32 character password for your camera.
Which we will do.
And you want to specify a recovery email address in the event you forget that password,
they'll send you a link to reset it a lot of people skip this process.
and it's very important
because more often than not you will forget this overtime. So we'll go ahead and save that
the initialization has been completed if you want to use the phone app to view this networks camera
there's a link to this process using the phone app above right now but basically you can download the
Dahua DMSS app on your mobile phone. Once you do that, you can scan in this QR code and once you do
that, you'll be able to pull up this camera live on your phone this is called p2p technology. It's
very simple. No more more port forwarding and all that stuff. We are going to auto check for
updates. perfect and then we can log into the camera with the password we just created okay
okay once we log in you can see the camera is actually looking at a wall fascinating, but the
purpose of this video is to change the internet settings so we're going to go over here to setting
and before we deal with the network settings we
can change the time because i see that is off just go into system
general date and time and hit sync with pc and that will change the time date stamp of your
camera to match the pc um so we've done that but yes we're going to go to network and we're going
to go to tcp ip on a Dahua camera it would be the same thing with Hikvision or whatever
vendor you're using. Here is static, that's how it's shipped by the manufacturer. We simply want
to switch it to DHCP and once we do that and hit save the ip camera will reboot. We can now put our
computer back into DHCP mode and we will see this camera will change its ip address from the 192 168
1.108 to our gateway which is 192.168.0.1. Okay let's go ahead and do that there's the save
and it's rebooting. Alright, we are in the home stretch now! What we have to do is put our network
settings for our computer back into DHCP mode.To do that, we're going to hit the control button on
the keyboard in the letter x once again. We are going to go back into network connections and
we're going to pick wi-fi with this computer. We are connected to the internet via wi-fi
and we're going to go to our properties and as you can see there is where we have
um change from dhcp to manual connection at 192.168.1.9 so we're just going to edit this
and go back to dhcp just like that we're going to hit save make sure the settings applied
and then we can reconnect to our internet
and once again the computer will be assigned an ip address by our router okay all right
at this point we are reconnected properly to our internet and if we open our onvif device manager
our scanner should now locate that camera on our gateway as you can see it rebooted and it
is on the 192.168.0.19. So, we can open that up via any browser at its ip address 192.168.0.19.
just like that there it is so there is a little bit to it when you have problems when you have
issues finding those cameras on your network it's not that they are not there they're there
um they're just not on the proper gateway so we want to change the gateway of the camera
to match the gateway of your routing device once you do that using the steps we just covered you
will be able to find the camera using advanced ip scanner or the onvif scanner that we just shared
hopefully the video was useful as always we'll see in the field
