Communicating between VLANS

Model: TL-SG1016PE
Hardware Version:
Firmware Version:

I have a NVR which I can access on my LAN, I would like some IP cameras isolated on a VLAN to access the NVR using an 802.1Q managed switch only.

I want the cameras to connect to the NVR without wasting router resources, can I do this through a switch with 802.1Q? I am thinking of having separate VLANS on a single /24, is this possible (does this make sense)? I don't quite understand how (if) I can get this to work without the simple method of traffic being routed between different subnets for different VLANS

Hi Mango

 

The 802.1Q VLAN can help you isolate your IP cameras and NVR. If you want IP camera can connect to NVR, you switch need to support inter-VLAN routing. 

If you set all devices in a single /24 subnet, they still cannot access each other because the devices transmit data based on layer 2 network and VLAN have isolated them.

If the switch support inter-VLAN routing, the different devices can access each other based on layer3 network. The data will not be isolated by VLAN.

Can anyone help me out in connecting the cameras to the NVR without wasting router resources, can I do this through a switch with 802.1Q? - Even for some of my websites like Carpet Cleaning Melbourne, these VLANS communication is a problem in connecting with cameras for a screenshot.

Hi Stuart_Napier

 

If you can tell more detail about your issue, maybe more prople can help you. If your camera cannot connect to NVR in your local network, you should check the VLAN configuration and your devices' IP address. Make sure they are in the same VLAN. If they are in the different VLAN and subnet, you need switch support VLAN routing.

I have created a new thread here, as I am wondering specifically about connecting between LANs on a managed switch

Hi

 

You can put the NVR and cameras to the individual VLAN. Then the multicast data and broadcast data will not flood to other VLANs. If you still need the NVR and camera can access the internet, you may need the inter-VLAN routing to make the NVR and camera can access the gatewat and access the internet.

Hey Andone,

 

It's cool that you are trying to be helpful here, but I am almost completly certain that this person is just a spammer.  Look at their two identitcal posts on this thread with different usernames and advertizing links.  Looks terribly suspicious to me...
