Reolink RLK8-410B4 is the most acceptable PoE outdoor surveillance camera system. RLK8-410B4 is a Reolink system that comprises four 4MP and 5MP PoE IP cameras and an 8-channel NVR with a 2TB HDD built-in for continuous recording around the clock.

Since Ethernet offers more bandwidth than a wireless connection, POE cameras deliver any camera’s most outstanding image quality. POE cameras are the most excellent option if you need a high-resolution camera that can be zoomed in to capture facial features or number plates from a distance.

One Ethernet cable is needed to power and transmit video from a Power over Ethernet IP camera. So long as you have a POE compacted connection to connect to the camera and a router on the other end, a PoE IP camera should work.

PoE (Power over Ethernet) cameras from Amcrest have a video quality of roughly 4-megapixel, making it possible to broadcast HD video over great distances at a reasonable cost. 

PoE IP cameras allow you to increase your power range by transmitting both energy and the internet over the same ethernet wire. Keep in touch with the things you care about no matter where you are with Amcrest PoE IP cameras.

What Is A POE Camera?

What’s all the fuss about POE safety a camera, anyway? What are they doing in the first place? Since POE cameras are on the rise, many people are asking themselves these issues. 

Everybody seems to be opting for them and the latest current safety camera option. Because the trend is catching up with everyone, it’s preferable to invest your time learning about it and why others are pursuing it. You’ll have a better sense of all the hype as soon as you finish reading this article.

How POE Cameras work?

Only a few items are required to get a PoE camera system up and running: All of the components needed for a PoE camera system, along with a PoE NVR, Ethernet connections, as well as a network PoE switch. 

The cameras communicate footage to the DVR, which encodes and analyzes the footage for view in analogue camera configurations. 

There is no such thing as an IP camera. Instead, they do the hard work by processing the pictures and then sending them to the NVR, in which they are either stored or watched.

It’s as simple as plugging an Ethernet connection from a camera into an on-premises PoE switch and an NVR onto a network switch. 

You can power up to four cameras using a single network switch’s multiple PoE ports. Reduced cabling and more efficient operations are the benefits of PoE camera systems.

You may choose from a variety of ways to watch video clips. A VGA or HDMI cable and a USB mouse, for example, may be used to connect a display directly to an NVR.

Alternatively, you will need a network router to connect the NVR to the internet for extrasensory perception. If you’re looking for a way to link your NVR to your WiFi network, many of today’s NVRs have WiFi capability.

It is possible to connect numerous cameras to a PoE switch or converter to distribute electricity and internet connections through the cloud-based NVR. Then, using cloud-based software, you activate and link your cameras and gateways. Video streams may be accessed and streamed from any computer, mobile device, or VMS (video management system).

Advantage And Disadvantages Of POE Camera?

PoE surveillance cameras provide many advantages for enterprises and organizations. They often use the most recent innovations, resulting in an advanced system. 

They are more adaptable than analogue equivalents due to their IP PoE cameras’ capabilities, but they are also more sturdy due to the former’s more accessible wiring. This security camera system’s PoE features provide the following advantages:

  • Flexibility

Cables are a significant downside of analogue camera systems and video quality. Power is supplied by one cable, while network connectivity is provided. Power and network connectivity are provided via the same cable in PoE security camera systems. 

Scaling your system is easier since you don’t have to place an electrical outlet by that. Moving the Ethernet wire is needed to remove or relocate the camera.

Analogue surveillance camera systems need the usage of coaxial wires, but not with a PoE solution. Analogue systems are more challenging to install and less flexible because coaxial wires are more significant and stiffer than Ethernet connections.

  • With Poe, You Can Put It Anywhere, In The Ceiling

A PoE device’s deployment and mobility are simplified by the device’s ability to incorporate power into the Ethernet wire itself. AC power plugs are unnecessary! 

Power over Ethernet (PoE) is an excellent solution for difficult-to-reach places, such as high ceilings or open air. Installing security cameras is made more accessible since you don’t have to worry about finding an AC power supply for each one.

  • Streaming Data

Power over Ethernet (PoE) has become a vital part of the infrastructure when it comes to community connection. An increasing need for more incredible data speeds is accompanied by the requirement for quicker upload and download speeds and a stable connection. 

With PoE, you may get up to 1Gbps of data transfer using ethernet cables of both Cat5 and Cat6.

POE May Have The Following Drawbacks

It won’t start because there isn’t enough electricity. Most IP cameras can be powered by the 802.3af PoE standard’s maximum output power of 15.4W, suitable for most applications. 

High-power devices, such as networked PTZ cameras, cannot use this much output power.

  • A Single Point Of Failure

In most cases, when a PoE switch links to several IP cameras, all Cameras will cease operating if the PoE network switch faces any issues.

  • Expenses For Both Equipment And Maintenance

A separate power source is preferable to PoE technology’s increased maintenance requirements when it comes to security and reliability.

Introduction To Reolink Poe Camera?

When installing CCTV home cameras using PoE (Power over Ethernet), no power connection or adapter is required. Using Reolink PoE security cameras, you can get high-definition footage even in the dark with 12MP, 8MP, 5MP, or 1440P resolution.

Reolink 5MP PTZ

Pan, tilt and zoom (PTZ) cameras aren’t the best choices for every CCTV circumstance since they only allow you to aim the camera in the direction you want it to be at any one moment, and it may cost just as much to put numerous fixed cameras in the right place. 

But if you have an existing system, a PTZ camera might be a great way to get additional information before going to the next level, mainly if it employs intelligent alerts to bring your attention to questionable activities.

Part of the appeal of Reolink is the ease with which it may be controlled through the company’s app. There are other capabilities, such as two-way audio. However, the 5x optical magnification will give you a better view of the scene. 

For dawn photographers, time-lapse or flexible recording modes may be fun.

Pros –

  • Allows the user to record to a Micro SD card.
  • Apps for iOS, Android, Mac, and Windows devices.


  • Optical zoom might be extended

ReoLink RLK16-410B4

Installing your Reolink 5 MP PoE camera was a snap. Our router was hooked into the NVR; we used simultaneous Ethernet connections to connect and power our cameras. For our outside cameras, each cable had around 60 feet, which is enough. 

So we didn’t have to be concerned about putting them out in the rain or the sun since they were IP 66 certified, which means they are both water and dust resistant. Only the end of the wire that went into the cameras was left unprotected since we used the waterproof covers that came with the cable.

There was an RLN16-410 NVR included in the Reolink 5MP PoE system. A pre-installed three TB hard drive was more than adequate for storing the movies from the eight cameras that came with the system. 

However, two more hard drive sockets were available, each of which could accommodate a SATA disk of up to four terabytes. A spare was found, and we utilized it to boost the capacity to seven terabytes (TB). 

For our purposes, that’s around two weeks’ worth of video storage. In addition to supporting 16 cameras, the NVR was ideal for big houses or companies. We did not need that many cameras in a mid-sized home, but it was nice to know that we’d be able to install more if we did.

Pros –

  • As many cameras as your NVR can handle
  • Compatibility with the vast majority of home-based file transfer protocols


  • There aren’t many choices for free or paid cloud storage.

Reolink RLK8-820D4-A system

An NVR and four 4K cameras make this a formidable security system that can monitor many properties without further expenditure – and it can accommodate up to eight Reolink IP cameras if necessary.

NVR can record four layers for up to three days at the highest 8192kbps bit rate using H.265, but if you need more, the NVR can add 6TB inside (swap the hard drive) or 6TB externally (SATA connector) for a total of 36 days. However, even while you’re gone, you can still watch what the cameras are seeing using Reolink’s computer client, which can run on Mac, Windows and the web.

Set up correctly, you’ll be alerted on your android or Iphone phone if one of your teenagers borrows the car without your permission; the alerts will say, “the side door identifies person activity.”

Pros –

  • No Monthly Fee
  • Recordings may be saved to a MicroSD card in a camera.


  • Detection of human beings as opposed to specific individuals

Reolink RLC-410 twin pack

Compared to a complete NVR system, the Reolink RLC-410 twin-pack is significantly less expensive. However, it still offers many of the same features if you use one of the numerous third-party camera assistance programs they accept. 

You can wait and buy a Reolink NVR later (or another brand, but they seem less enthusiastic about that). 

When motion is detected, each camera includes a MicroSD card slot that may be filled. However, this feature is optional.

Even though these cameras have a resolution of 5 megapixels, the image quality is excellent both day and night, thanks to the 18 built-in infrared LEDs that are included. There’s plenty of fine detail in Blu-ray, thanks to its higher pixel count than in standard High Definition (such as Blu-ray). 

Even if you have enough Cat 5 or higher cabling sitting around to connect the cameras, you’ll need a PoE injector like the 802.3af 48V to deliver power to the system (or a capable NVR).

Pros –

  • A good value for the money
  • Detection zones and motion sensors


  • PoE injectors are needed.

Do Reolink POE Cameras Work With Any Poe NVR?

The functionality of Reolink PoE cameras & NVRs may be reduced if they are not connected to the internet. To connect the PoE camera straight to your computer, you’ll need an Ethernet cable.

How Do I Setup A Reolink Poe Camera?

PoE cameras may be installed in four different methods, but which one is optimal depends on the gear you want to use.

A POE Camera With A POE Switch Is Available

Simply connecting the PoE camera to the PoE switch, regardless of whether it’s a controlled PoE switch or an uncontrolled one, will give the camera both data and power.

With A Poe Injector

As a result, you must use a PoE injector to power your camera. The PoE injector will carry your switch’s data, which may also power your PoE camera.

With The Help Of The Poe Camera Hub

Trying to connect many PoE injectors to the same network while installing a large number of PoE cameras may be a real pain. Instead, a PoE hub should be installed. One power source can power many PoE cameras, making the setup more straightforward.

Power Over Ethernet (Poe) Camera With NVR And Router

If your router isn’t PoE compatible, you’ll need to set up a PoE NVR to power and transmit video to your PoE camera.


The reliability of power-over-ethernet systems is unmatched. A mature technology, PoE has seen a lot of evolution over the years. Nowadays, it’s a standard utility used in switches and routers, wall clocks, POS kiosks, access control, and many other devices.

PoE relies on physical components (cables and switches) even if the technology is pretty dependable. With every physical type of tech, high-quality components ensure long-term dependability.
