Connecting multiple IP Cameras together v1

Connecting multiple IP Cameras together v1, As IP cameras become more affordable, it's becoming common for people to expand their IP CCTV while minimising additional costs or efforts. However, the key challenge has always been setting up a new Cat5/6 cable to the to the rest of the system.

In scenarios where you already have a cable installed between the network and, say, your garage, where installing more cables is difficult, having to run a second cable is not ideal. However, we've discovered the Vigitron Netmux Vi00103 POE Multiplexer, a great gadget that combines two POE ports on your network side into one cable, and then splits them again at the camera-end, to solve this problem.

Below is some more important information on the specification and capabilities of the Vi00103, as well as our 6-step instructions for using it correctly.

Connecting multiple IP Cameras together v1.

Instructions:​

Step 1:
.

Connect the two RJ45 cables from the Vi00103RX combiner, labelled “Port 1” and “Port 2”, to two available POE ports on your POE switch or NVR.

NOTE – The cameras do not need to be activated with a password. If you are connecting them directly to an NVR, then the Plug & Play feature will still work and activate the cameras; If you are connecting them to a separate POE switch, you will be able to access them and activate them on your network later. Plug & Play setups will also work when cameras have already been activated, as long that these are set with the same password as the NVR and have DHCP enabled.

step 1

Step 2:
.

Connect your single Cat5/6 cable to the port on the Vi00103RX combiner, which is labelled as “Port 1 + Port 2”.

step 2

Step 3:
.

Now, plug in the other end of the long single cable to the Vi00103TX splitter's “Port 1 + Port 2” RJ45 port.

NOTE – this cable cannot be longer than 100m / 320 feet

step 3

Step 4:
.

Connect your IEEE802.3af/at IP cameras or POE devices to each of the ports, labelled “Port 1” and “Port 2”, using another Cat5/6 cable for each.

NOTE – the length of these cables, and the long single cable between the Vi00103RX and Vi00103TX cannot exceed 100m / 320 feet in total, as this is the maximum standard range of POE. 

step 4

Step 5:
.

Green lights should appear on the Vi00103TX to confirm that each of the ports is delivering POE to your devices. If they do not, check the power supply to your POE source and all of your Cat5/6 cables are secure.

step 5

Step 6:
.

If you are connecting the cameras directly to an NVR as “Plug & Play”, then they will connect and appear automatically after a minute or two. Alternatively, if you are connecting them to a separate POE switch, then they should be discoverable on the network and allow you to adjust any network settings so you can add them to your CCTV system.

Key benefits:​

 Allows you to use a single cable for two cameras
 Useful if you already have a cable in place but want to add an additional camera without the hassle of routing another cable.
 Works with NVRs with POE ports and a Plug & Play feature, as well as on separate PoE switches.
 Entirely passive system (no additional power supply is needed).
 Compatible with PoE+ (IEEE802.3at) on both ports.
 There is an LED on each port of the splitter device to indicate the POE status.

.

Limitations & key points to consider:​

 Two free ports on your POE source are still required.
 When setting up your cameras, it's important to take into account the POE budget of your switch. Keep in mind that this budget won't decrease the power draw per camera.
 Use a high-quality cable and ensure proper termination to avoid issues with transferring data to both cameras, as twice the amount of data will be transferred.
 Provides up to 37W of power to each device, with a total power budget of 74W.
 Only compatible with IEEE802.3af (regular POE) and IEEE802.3at (POE+) devices.
 It's important to note that the cable run between the combiner and splitter devices should not exceed 100m. However, you can easily extend this by up to 100m with the Vi2300 UTP extenders.
 Keep in mind that the cable length from the POE switch to the cameras should not exceed 100m either. If your cable is already 80m, then the cables running between the splitter and each camera must be under 20m.

Can I connect more than one camera via a POE switch to a single POE port on my ?

In some scenarios, it can be useful to have several cameras connected to a POE switch but to keep that switch directly connected to your NVR rather than the local network.

If you are able to connect each camera to its own POE port on your NVR, then this is generally advisable, as using a Plug & Play is much simpler and avoids the need for extra hardware or power supplies.

However, if your NVR is closer to your POE switch than it is an available access point to your LAN, then it can make connecting the cameras simpler whilst avoiding the need to have an ethernet cable running from each camera back to the NVR.

One other benefit of keeping the cameras connected directly to your NVR this way, rather than connecting them across your LAN, is that the connection does not rely on your router being operational. Provided the NVR and POE switch are working, the cameras will remain connected and recording regardless of any problems that might occur with your local network.

These seven steps below explain connect multiple cameras on a POE switch to a single port on your NVR.
.

.

1.Plug each camera into a numbered port on your POE switch and connect the switch to your LAN (router) via the Data/uplink port, so those cameras are visible in SADP on your PC.

2.Activate any camera that shows as “inactive” with a password.

NB – keeping the same password for each will simplify the entire process.

3.Turn on DHCP on each camera by selecting them in the and ticking Enable DHCP in the right-hand window. Enter your password and click Modify to save the change. This is key for everything to work.
4.Now, disconnect the POE switch from your network and reconnect it to your chosen POE port on the NVR, whilst keeping the power supply to the switch connected.

5.Disable the NVR's POE on the channels that the switch is connected to and those that you have reserved for the cameras. To do this, open the NVR's web GUI and navigate to Configuration > System > Channel Management > POE Channel. From there, untick the channels you want to disable and click Save.

NB – for example, if your POE switch is connected to port 8 of the NVR, and you would like to add your cameras to ports 1, 2 and 3, then you will need to disable the POE on ports 1, 2, 3 and 8.

6.Go to Configuration > System > Channel Management > IP Camera, and click Quick Add. This will bring up a list of the IP cameras connected to your local network, as well as the ones connected to the POE switch. Select the cameras with a 192.168.254.X IP address, as these addresses are on the NVR's IP range and so must be the cameras connected directly to the NVR via the switch.
7.Once you have ticked the box for each camera you would like to add, click on OK to add them to the reserved channels. After a few seconds, the Status column for those cameras should change to Online, indicating they have been successfully connected.

.

Important things to note:​

 Unless you are using a 12V power supply for your cameras, this will only work with a POE switch, as the ethernet ports will need to provide power to the cameras and a normal network switch does not allow power to pass through it from the NVR's POE ports.
 If the power supply from your switch is disconnected then your cameras will stop recording to the NVR.
 Please ensure your POE switch has a suitable power budget to handle the cameras you plan to connect to it. The maximum power draw of a camera can be found in its datasheet.
 This will only work with Hikvision cameras, so anything added using the protocol must be connected to its own POE port on the NVR or across your local network via a different switch.
 If the cameras are not connecting with DHCP enabled, then you can also manually assign the correct IP address for the channel you would like to put the camera on using the SADP tool.
These should be 
192.168.254.2 for channel D1; 192.168.254.3 for channel D2192.168.254.4 for channel D3; and so on… The final number of the IP should be one higher than the channel.
The gateway address should also be set as 
192.168.254.1.
You should then be able to add the cameras either via the 
Quick Add button or by the Manual adding method when clicking the edit button for that channel.

How do I use a Hikvision NVR's “Virtual Host” feature?

One of the most successful selling points of a Hikvision NVR to many small-setup customers is the “Plug and Play” functionality that simplifies the setup process of their system. However, plugging a camera directly into a port on the NVR, unfortunately, does not allow you to access the camera via its own internal LAN IP using a browser due to it being on the NVRs internal network, and this can significantly reduce the number of configuration options you have access to.

The NVR does allow you to configure many options for each connected camera, but some essential features are only accessible via connecting to the camera itself (such as audio codec options). This was of course a big problem previously.

With the advent of newer
and models of NVR, Hikvision has introduced a feature called Virtual Host. Activating this feature turns your NVR into a “host” for the cameras allowing you to connect to them via a browser. Essentially, the NVR forwards all traffic received from your browser to the appropriate camera you're trying to connect to, eliminating the biggest problem of plug and play functionality.
.

.

Step 1:​

First of all, access your NVR via a web browser. If you do not know the LAN IP of your NVR, download Hikvision's tool SADP tool, which scans your network for any Hikvision devices that are connected and allow you to see and change their network settings, including the IP address.​
