The number of channels on the NVR dictates the maximum number of cameras it can support. Connecting it to an 8-port switch won't expand this capacity; it will still show a maximum of 4 cameras.

Reolink's support for cameras connected through external switches or routers, especially non-Reolink devices, can be limited and might not always work as expected. While Reolink NVRs are generally compatible with Reolink cameras, there could be limitations or specific requirements when adding cameras through a PoE switch, especially if the cameras are from a different manufacturer. Ensure all devices are compatible and that you're aware of any limitations. Ensure that the cameras connected through the PoE switch are on the same IP network as the NVR.

No need. The PoE switch can connect multiple cameras together, and you can upload all the video to NVR from the PoE switch.

@@Fastcabling thank you

You still can access all the cameras through the NVR. As long as you set the password for both cameras and the NVR. I think there is no much difference regarding the security. Creating a subnet can avoid the IP conflict since the cameras will have different subnet. However, it did create one possible issue, the NVR can't see the IP cameras from the local network. If you have one camera which you can't bring the cable to the NVR, and you can't leverage the network topology.

You can either connect the router and NVR to the same PoE switch or connect the NVR and PoE switch to the same router. Either way will work.

You can run a quick test. Remove 4 cameras on the 8. ports PoE switch and see whether you can see the video from the one last camera. Just remember you probably need to configure the NVR to link that camera.

I think the PoE NVR has created a private subnet to take in the cameras from those POE ports. Meanwhile the NVR the public subnet to talk to the LAN. That is why the cameras in the LAN can't reach the NVR, because there are two different subnets in the NVR. You can get the cameras from the LAN into the private subnet of your NVR. You might need another NVR to take in the cameras from the LAN.

@@Fastcabling cold he fix this by giving the IP address to the NVR from the cameras on the LAN?

Yes, you can connect the PoE switch to the LAN port on the NVR with only one Ethernet cable.

Sounds like a poe injector Are you sure your "poe switch" has a switch

The PoE injector is a type of single-port PoE switch that can only provide power to a single device, which limits your ability to expand your network. If you want to know more about their differences, please refer to our latest video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-i-1fHqDMBpE.html

The number of channels on the NVR dictates the maximum number of cameras it can support. If you have a 4-port NVR that supports 8 channels, you can add more cameras above the specified physical ports.

Absolutely!

Yes, you can still test the camera's functionality by connecting it directly to an NVR. Check the camera feed for any issues, such as a clear or distorted image. If the camera has pan, tilt, and zoom (PTZ) functionality, test these features through the NVR's interface. But please keep in mind that this method is primarily for testing the camera within your local surveillance system. To access the camera remotely, you will need an internet connection.

No, the NVR is usually powered through its own power supply, not via PoE from the switch. In this video, we're trying to connect it to a larger network via a PoE port on an external PoE switch to connect more cameras. The switch will not supply power if it's not requested by the device. The connection primarily serves for data communication. Actually, you can connect the switch directly to a RJ45 Ethernet port on the NVR.

Much appreciated!

You will have to check the capacity of your NVR. If the NVR doesn't offer extra channel to take in more camera, you can't add more cameras to your NVR.

No, there is no issue with your design. I assume the AC power source is ready at the garage. Otherwise, you can consider the PoE powered switch and send the power from your house.

You need to double-check all physical connections, including Ethernet cables, to ensure they are properly seated and connected to the correct ports on the switch. Verify that the power source for the switch (PoE or external power supply) is functioning correctly. And you can disconnect the new switch from the network and see if the existing network returns to normal. This will help determine if the issue is related to the new switch or not.

It seems like your Hikvision NVR might not support automatic recognition of the cameras. Try manually adding the cameras in the NVR's settings using their IP addresses to see if that resolves the issue. Good luck with your setup!

Yes, it will work.

It's a simple process to add a wireless network bridge between the two buildings especially since its a short distance. I use a UeeVii 5.8ghz between my workshop and House which is about 25m and it works very well. 8 port POE on the shed side which I run 3 cameras and my LAN still moves along nicely. Got mine in Australia for around $100 AUS . Very simple set up.

@@Hungry_Hunter I appreciate your responding but you answered my question by telling me what you would do. I am asking you if my setup will work with a ethernet cable connecting 2 POE switches in 2 different buildings,

Since the Ethernet cable is existed, yes, you can set PoE switch both building and leave the NVR at the main building. The cameras in another building can return to the NVR. What you think of is correct. You have everything you need.

To set up a 32-camera Reolink system using Power over Ethernet (PoE), you'll need to consider several factors to determine how many PoE switches you'll require. You'll need to check the power requirements for each Reolink camera. Different models may have varying power needs. For example, if each camera consumes around 15 watts, you can calculate the total power needed for all 32 cameras. PoE switches have a maximum power budget or wattage they can provide to connected devices. For instance, if you have a PoE switch with a total power budget of 250 watts, you can calculate how many cameras it can support. If your power requirement exceeds the capacity of a single switch, you'll need to distribute the cameras across multiple switches and possibly daisy chain them for scalability. And you need to ensure your network infrastructure, including the switches and cabling, can handle the bandwidth requirements of all 32 cameras. Remember that it's essential to plan your network carefully to ensure reliable and efficient operation. If you're interested, we can also provide free solution design to our customers.

If your NVR supports PoE, you can directly connect the PoE extender to the NVR. If not, you will need a PoE switch to provide power to the extender.

When you connected the PoE Switch's uplink port directly to the NVR, it established a more direct and potentially faster pathway for data from the cameras to reach the NVR. This setup minimizes the number of hops and potentially reduces latency and bandwidth issues that can occur when more network devices (like additional routers or switches) are involved in the data path.

The Dahua NVR4104HS-4P-4KS2/L is indeed a PoE (Power over Ethernet) NVR, and it supports PoE devices, including PoE-enabled cameras.

Yes, as long as your NVR can handle 24 cameras.

Yes, you can connect the NVR and PoE switch directly to your router.

A1: some NVRs are vendor-specific. If you’re unsure about the compatibility, you can contact the manufacturers or refer to the specs. If they're ONVIF-compatible, that should be fine. A2: That depends on the capacity of your NVR. If it can handle 8 channels, then you can view 8 cameras simultaneously. However, if it only has 4 channels, it's limited to connecting and recording four cameras at any one time.

Connecting two IP cameras directly to the PoE NVR and the other two through a PoE switch should work fine. Just ensure the PoE switch supports the required power and bandwidth for all cameras. Distance shouldn't be an issue if you're within the network's limits(328ft max.).

Should work fine without any problems so long de distance is not more than 100 metres between the POE and NVR.

Yes it will

The number of channels an NVR can support is usually fixed by its physical hardware specifications but you can add more cameras if your NVR supports using a PoE switch for additional cameras. If you're interested, you can refer to this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vwTmfbe8bSU.html. Or you can combine two NVRs together to increase the availability of camera channels. Some NVR software solutions, particularly those designed for PC-based systems, may allow you to add additional camera licenses to increase the number of supported cameras.

Ordinary PoE switches can only work within a limited temperature range of 0~40°C, but we have also developed a series of outdoor PoE switches that can work at -40°C~60°C. Outdoor PoE switches: www.fastcabling.com/product-category/outdoor-poe-switches/ Industrial Switches: www.fastcabling.com/product-category/industrial-ethernet/

The number of channels on an NVR indicates how many cameras it can record simultaneously. If your NVR is a 4-channel NVR, it can handle and record video feeds from up to 4 IP cameras. The NVR in this video can handle more than 4 cameras. If you want to run 12 cameras simultaneously, you’ll need an NVR that supports at least 12 channels.

Is there a way to expand the existing NVR to to use more cameras.

If your limitation is not the number of IP channels but rather the physical connections or power supply, adding a PoE switch can help, just as demonstrated in the video. However, if your current NVR is at its capacity, consider upgrading to a larger model that supports more cameras or add an additional NVR. You can consider implementing VMS that can handle inputs from multiple NVRs or directly from IP cameras. VMS solutions can be more powerful and offer advanced features like analytics and remote access. For some scenarios, especially where on-premise hardware expansion is limited, consider cloud-based video recording solutions.

You will have to check the capacity of your NVR. If the NVR doesn't offer extra channel to take in more camera, you can't add more cameras to your NVR.

If you have more cameras than the NVR can support directly or you need to position cameras in locations far from the NVR, an external PoE switch can be used. You can connect some cameras directly to the NVR (if available ports) and others to the PoE switch. The PoE switch will need to be connected to the NVR (usually via one of its LAN ports) to transmit data from the cameras connected to the switch. When using an external PoE switch, ensure that the uplink to the NVR can handle the bandwidth generated by the connected cameras, especially if you're using high-resolution cameras. The NVR's network interface (where the switch is connected) must support enough throughput to avoid bottlenecks.

Thanks my coach and mentor.

The PoE switch is onvif-compatible. If you need to connect more PoE cameras than the NVR can directly support, a PoE switch can be used to provide both power and data connectivity to additional cameras. However, the total number cannot exceed the NVR’s channel capacity. For example, if an NVR is described as an 8-channel NVR, it can handle up to 8 cameras, regardless of how many network ports it has or how many cameras the connected network can support.

It depends on the NVR's capacity. If you have a 16-port PoE NVR, but it supports 32 channels, then it'll work. However, if your NVR supports only 16 channels, it can only manage and record video from up to 16 cameras.

Hi, can you please email us at support@fastcabling.com? Our support team will get back to you as soon as possible, and please include the camera specs.

Here is the NVR you saw in this video. www.fastcabling.com/product-category/network-video-recorder/

The cameras can connect to the PoE switch, which in turn connects to the NVR, and the NVR handles the connection to the internet.

@@Fastcabling many thanks

My pleasure.

You can check the indicator on the PoE switch or check the NVR's interface to see if the camera is recognized and connected.

Connecting your PoE NVR to a router allows you to access your security cameras remotely. If you only need to view the camera feeds locally and don't require integration with other network devices, you can set up your PoE NVR and cameras as a standalone system.

A subnet is a segment of an IP network where all devices share the same IP address prefix. Different subnets isolate traffic and devices, while the same subnet allows direct communication between devices. PoE Ports and LAN Port on the Same Subnet: All devices, including the NVR, IP cameras, and any other devices on the local network, share the same IP address range (e.g., 192.168.1.x). Devices can communicate directly with each other without needing additional routing. Remote access to both the NVR and cameras is simpler since they are on the same network. PoE Ports on a Different Subnet from the LAN Port: The NVR creates an isolated subnet for the IP cameras connected to its PoE ports (e.g., 192.168.2.x), while the LAN port is on the primary network (e.g., 192.168.1.x). Camera traffic is isolated from the rest of the network, which can improve security and reduce network congestion.

You might need check whether both cameras and the NVRs are Onvif compatible. If both cameras and the NVR support Onvif, you have a good chance it works with each other.
