I'm not following the choice between an NVR and switches. Shouldn't the choice be between an NVR with one port for each camera connected directly or an NVR with one or more switches inbetween the cameras and the NVR? For instance, I'm setting up a small system at a vacation home with a maximum of eight cameras. However, three of the cameras are for nature/scenery viewing where the rest are for surveillance. The nature cameras are from 200' to 300' away from the NVR through woods and could be exposed to lightning, etc. I decided to use a switch between the cameras and the NVR for these reasons: 1. I need to access the nature cameras outside the NVR so having access to another device on the same network facilitates this. 2. If any camera needs to be configured directly, the NVR can be bypassed. In contrast, if the camera is plugged directly into the NVR, it could require disconnecting it, plugging it into a computer to configure. 3. Having a switch between the cameras and the NVR should provide better isolation with a lightning strike or surge. I now see you have a more recent video that discusses this exact issue: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-v_Aa-oVoAk8.htmlsi=PmvYCvcjWpQiAvH4
Will it be able to amplify the data transfer speeds b/w lan to lan pc connections since i was using a lan to lan connection b/w two pcs and i got very slow speeds of 10mbps for data transfers even though the pcs were kept at 1 metre distance
If i want to add another nvr that is isolated from the main network but is on the same network as the first nvr. Should I connect the lan1 of nvr2 to the switch connected to the lan2 of nvr1.
Does the second switch need to be POE as well or can it connect directly to normal switch or device? IE does the second extender need POE power from the extension end?
If the cameras are only used for local monitoring and recording (for instance, through an NVR, on the same local network), then you do not need an internet connection. The system can operate fully on a local network, and recordings can be accessed directly from connected devices without the internet.
How would you like to expand your business and channel right now, dear? Have you considered placing advertisements? Can I discuss a service provider with you?
A PoE extender must be added if you want to extend the distance further and achieve a faster speed (100Mbps). BTW, for 4K PTZ cameras, the bandwidth requirement may increase to 8-20 Mbps. To ensure a good signal quality, it's also recommended to use the PoE extender.
Would this work if i connect the cameras directly to the poe switch (which is connected to the router) , then connect the nvr to a cable that is also connected to the same switch? All my cables connect to a central conduit (which house the router and a switch), but i can not fit the nvr box in the same conduit. So i want to put my nvr box in my room.
You don't have to hardwire the poe switch to the NVR. Just make sure they're connected to the same network (router). Since the NVR is connected via a network cable (from your room to the central conduit where the router and switch are), it can record and display the video feeds from all the cameras. Also, verify that your NVR has enough channels to handle all the cameras.
Can we use both fiber string A and B on the end of sfp port on the switch and the same thing on the other end of the sfp port switch to make it in Full Duplex Mode communication? In your example showing half duplex because you Are using single fiber, am i right? Thank you.
Can we connect the fiber cable from 2 switches on the left to the Uplink port on the right of fiber switch near NVR? And use the normal port of sfp fiber switch on the right going to router? Thanks
No, the uplink ports on the 8-port SFP port switch are 2x dedicated 1Gbps Ethernet ports, and you cannot connect the normal SFP port on the fiber switch to the router. Only fiber to fiber and ethernet to ethernet.
Could you answer a few questions for a newbie like me? 1. Would the 2 media converters add latency in this setup compared to a direct ethernet connection that is under 100ft (cat 6a)? 2. Would the 2 media converters add 2 additional invisible point of failures incase something goes wrong?
The fiber media converters might add a tiny amount of delay due to the conversion process, but the difference would be so small (fractions of a millisecond) that it won't affect the system. They might introduce points of failure. Over time, like any hardware, media converters could malfunction due to heat, wear, or environmental factors. However, media converters are generally reliable if you use good-quality devices and set them up properly. You can have a redundant setup if uptime is critical, like using dual media converters with a failover mechanism.
The PoE switch needs to be connected to an external power supply. But you can use powered fiber cables to transmit data and power simultaneously to the switch, or you can choose to power it with solar panels. Add a 48V voltage booster so you can boost 12V/24V solar power to standard 48V. 1. Power over Fiber: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QZqXNbv3Iw8.html 2.

This is brilliant. I can run one fiberoptic cable to under my deck which has an electrical outlet. I can then use an outdoor enclosure and connect fiber to a switch that has POE. This also reduces risk of a lightning strike because I don't have a CAT cable going from my network rack to outside, the fiber is made of glass.
Thanks! If you're interested, you can also watch this video on powered fiber cable: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QZqXNbv3Iw8.html. We've designed a series of composite/powered fiber optic cables that can transmit data and power simultaneously over a single cable.
if the nvr has 4 ports does it work with 24 ports poe switch? or does it max at 4 ports as well? or are there some hardware constraints for this scenario?
It depends on the NVR's channel capacity. If it can handle up to 8 channels, it can connect up to 8x cameras at once even if there are only 4 physical ports. But if it only supports 4x channels, then it will not work. The NVR is limited by the number of channels it supports, not the number of ports. By adding a PoE switch to the NVR, you can definitely add more cameras to the system, but it's always wise to check how many channels (cameras) your NVR supports. Also, you need to make sure your network has enough bandwidth to handle the data from all the cameras, especially if recording in high resolution.

Sign up here👉www.fastcabling.com/trade-account/ Product link: www.fastcabling.com/product/8-port-10g-sfp-managed-switch/ FYI, this kit includes an 8-port managed SFP+ switch (Layer 3) and a 10G SFP+ to copper module.
Unfortunately, the maximum range for this long-range PoE+ switch is 800 meters. At this distance, the network speed will be reduced to 10Mbps. Even if you add another PoE extender to the link, the signal strength is too weak to be duplicated. Moreover, power can never be regenerated meaning there'll be power loss when it hits a certain threshold.
You can connect two PoE switches using either: 1. Normal Port to Uplink Port: This setup is ideal if one of the switches has an uplink port with higher bandwidth (e.g., 10G or 1G), and the other switch's normal port is only 1G or 100M. 2. Uplink Port to Uplink Port: This is typically used to create high-speed inter-switch links for large data transfers or connect the access/distribution switches to the core switch. 3. Normal Port to Normal Port: This is often used in smaller networks where you don't need a high-speed backhaul between switches. Modern switches support Auto MDI/MDI-X, which automatically detects and adjusts the pinout of the connection (so crossover cables are no longer necessary).
FYI, this long-range PoE+ switch can only transmit data up to 800 meters at a reduced speed of 10Mbps. If you need to extend the network to 1km, you can use fiber optic cables (up to 20km) or wireless bridges (1~5km) instead.
Can we use pre made fiber optic cable as fiber back bone in any data application for structured cabling and cctv back bone? So fiber optic patch panel is no longer required because special tools are needed to terminate each fiber core into pigtails of said panel?
While using pre-made fiber optic cables can eliminate the need for fiber optic patch panels in smaller setups, you might still want to consider a patch panel in larger or more complex networks. Patch panels allow you to easily connect, disconnect, and reroute connections.

By regenerating the power and data signals, the PoE extender helps maintain the necessary voltage over longer distances. Pure copper cables are an excellent choice for long cable runs because they have lower resistance and better conductivity than CCA cables.
In many cases, a 10G SFP+ module will not work properly in an SFP port designed for 1G modules. SFP ports are typically designed for speeds up to 1Gbps, while 10G modules have higher data rates. However, you can use devices with lower speeds (like 1G or 100M) in a 2.5G port switch. The switch will typically negotiate the highest compatible speed with the device.
In this case, we're using BiDi SFP+ modules which can achieve full duplex communication, meaning you can handle both directions of traffic over a single fiber strand. www.fastcabling.com/product/single-mode-bidi-sfp-fiber-modules/
I have a tp-link access point with tp-link poe injector, i did the exact same connection and the access point powers up but doesnt have internet and it doesnt show up on the wifi list. It used to work, but i switched to longer ethernet the it didnt, how do i fix?
Log into your router or use the TP-Link app to see if the AP is detected and getting an IP address. If not, reset the access point to factory settings and reconfigure it. If the issue persists, please contact the manufacturer for further instructions.
I want to use a 160 meter cat 6 caple But the internet connection cant go this distance I want to use something in the middle to make the connection work correctly And i don't have a poe switch iam only useing a router with out poe Can you help me Thanks for your assistance And thanks for the video
You can connect a PoE injector to your router first. It will provide power and data to the poe extender. Typically, a single PoE extender can add an additional 100 meters of cable length. In your case, for 160 meters, you would need one PoE extender placed between the 100 and 160-meter point. Segment 1: From the PoE switch to the PoE extender (~100 meters). Segment 2: From the PoE extender to the endpoint (~60 meters). If it's a continuous cable, we would suggest you use a long-range PoE+ switch. By enabling the dip switch, you can extend the range up to 250 meters (continuous cable run) though at a reduced speed of 10Mbps. Moreover, by connecting a PoE extender to one of its long-range poe ports, you can extend the range to 500 meters at 100Mbps. www.fastcabling.com/product/800m-4-port-long-range-poe-switch/
A GPON system can support up to 128 units per OLT port. GPON offers 2.5 Gbps downstream and 1.25 Gbps upstream, while EPON provides 1 Gbps for both upstream and downstream. In terms of efficiency, GPON has more efficient bandwidth allocation with Dynamic Bandwidth Allocation (DBA), providing better performance for high-demand users. Overall, EPON is simpler and cheaper for smaller setups, while GPON is better for large-scale deployments requiring high-speed connections.
If you're looking to combine multiple network sources, such as for failover or load balancing, this is done using a dual WAN router or a load balancer before the OLT. The OLT would then remain connected to a single internet source.
It's a PoE media converter which can transmit optical signals and power simultaneously to the end device. www.fastcabling.com/product/waterproof-industrial-hardened-grade-fiber-poe-media-converter/
The more channels you display at once, the smaller each feed will appear. You can limit the number of channels displayed simultaneously on the screen to a more manageable number, such as 4 or 9 cameras per view, and switch between different camera groups as needed.

When choosing an NVR for cameras, you should consider these key factors: 1. Channels: Ensure the NVR supports the number of cameras you plan to use. 2. Resolution: Match the NVR’s resolution support (e.g., 1080p, 4K) with your cameras. 3. Bandwidth: Make sure it handles the combined bitrate of all cameras. 4. Storage: Check the hard drive capacity and recording duration. 5. Recording Modes: Look for continuous, motion, or event-based recording. 6. Remote Access: Ensure mobile or web-based remote viewing. 7. ONVIF Compatibility: Ensures compatibility with different camera brands. Also, if you don't have a PoE switch, you might need a PoE NVR to power cameras through Ethernet cables.
Just ensure the total camera bitrate does not exceed the NVR's maximum bitrate. Camera setup: 6 cameras at 4 Mbps and 4 cameras at 8 Mbps. 6 × 4 Mbps = 24 Mbps 4 × 8 Mbps = 32 Mbps Total bitrate = 24 + 32 = 56 Mbps. NVR supports 80 Mbps.This setup is valid because 56 Mbps < 80 Mbps.
You should look at the number of channels, resolution, bandwidth and bitrate, compression, storage capacity, recording modes, ONVIF compatibility, remote access, and user interface.
