Last update on 2021-04-15 / Affiliate links / Ratings / Images from Amazon Product Advertising API

Our take #1. Reolink RLK8-800B4-4K/8MP Security Camera System

The Reolink RLK8-800B4 4K PoE Security Camera System is made up of four cameras and a network video recorder (NVR). I’ve kicked off this review with the Reolink system because it’s one of the few 4K security systems on the market that also offers one-way audio, which I think is a real selling point. You can, therefore, get audio as well as visuals to cover all your security concerns.

The cameras in this system are small bullet cameras, making them best-suited to mounting on the walls of your property. Cameras are suitable to be used both indoors and outdoors, so you have a range of options when it comes to deciding where to put them.

Featuring an easy-to-use plug and play design, this camera security system should be simple to set up and begin using immediately, even for beginners.

  • 4K Ultra HD: The Reolink 4K Ultra HD PoE camera provides up to four times the clarity of 1080p.
  • Plug and Play PoE System: Easy set-up with a simple PoE connection.
  • Remote Access: Regardless of how many cameras you have, you can access them all remotely through the free Reolink smartphone app.
  • Continuous Recording: Reliable 24/7 recording with pre-installed 2TB HDD. Also compatible with an external hard drive for backup.
  • Easy to get started with simple PoE plug and play system
  • Offers night vision of up to 100 ft range in total darkness
  • Handy start-up guide, mouse, and Cat5 and HDMI cables provided
  • Fully waterproof/weatherproof
  • Remote viewing from desktop or mobile app
  • Does not offer advanced methods of motion detection, e.g., intrusion/line detection

If you are looking for a reasonably priced high-quality camera security system for your home, we think that this one from Reolink ticks all the boxes. It would be an excellent option for someone new to self-installing home security, as it’s so easy to set up. It’s aimed at small-medium size properties, but you can add further Reolink cameras if you feel you need to. The camera quality is high, and remote access from the smartphone app would be well suited to anyone who wants to make sure their home is safe while they’re on the go.

If, however, you are looking for advanced features, such as additional motion detection methods or the ability to trigger an external alarm, this may not fit your brief.

Overall, this product offers excellent value for money and has several useful and easy-to-use features. To see just how great the Reolink PoE Security Camera System is and to buy one of your own.

【5MP CAMERA】SMONET 5MP Home Security Camera System,6X5MP(2560TVL) Indoor Outdoor Weatherproof...

Last update on 2021-04-15 / Affiliate links / Ratings / Images from Amazon Product Advertising API

Our take #2. SMONET Wired Security Camera System

The SMONET Wired Security Camera System is a 4-camera security system that uses a digital video recorder (DVR) for recording. You get 4 bullet cameras in a weather-resistant casing, so you can mount them wherever needed.

We love the fact that you can get customized alerts for unusual movement direct to your smartphone, and the app seems straightforward to use once you’re set up. You just need to remember to connect the DVR with your router to get playback when you’re out and about.

Another great feature is the 1TB built-in hard drive, which offers a good amount of memory and storage space for all your footage. This would be well-suited to anyone who is looking to skip the hassle of having to install and additional external hard drive but doesn’t want cloud storage.

Because it uses a DVR rather than an NVR or PoE system, it takes a little longer to set up – but don’t let that put you off. We still think that this is a good quality camera system, offering clear images throughout the day and night.

  • 5MP Security Camera System: This SMONET system offers video monitoring that is both 300% clearer than 2MP(1080P) and 200% clearer than 3MP (even at night time)
  • Built-in 1TB Hard Drive: You don’t need to install an external hard drive – the built-in 1TB Hard Drive records 24/7. Overwrites previous footage automatically when full.
  • Remote access: Free app for Apple and Android enables you to access your cameras and watch live wherever you are.
  • Customizable alerts for motion detection: Receive alerts via your smartphone when unusual movement is detected. Easy to customize the set boundary for detection and adjust the sensitivity.
  • Clear night-time viewing
  • Fully waterproof/weatherproof
  • Remote viewing from desktop or mobile app
  • Good level of storage offered by the built-in hard drive, so no need to set up with separate storage device
  • Extra security from motion detection and immediate alerts straight to your phone
  • Some users have reported a complicated process in setting up remote viewing app

This camera system from SIMONET provides you with everything that you need to get your home kitted out with a reliable security system. While some users have suggested that remote viewing through the app is challenging to set up (and they required support from customer service), it’s easy to use once you’re logged in. As it’s a wired DVR system, it might take a little more time to set up than the plug-and-play models, but you get high picture quality in return.

If clear night vision is an important feature to you, this security system would be a strong option to choose. Equally, we think that this is a strong-all round wired system, so would suit anyone who is looking to get started with a wired camera kit, rather than wireless.

Check out this SIMONET wired security system and see for yourself the handy features it offers.

ZOSI 4K Ultra HD Security Cameras System, 8 Channel H.265+ 4K (3840x2160) Video DVR with 2TB Hard...

Last update on 2021-04-15 / Affiliate links / Ratings / Images from Amazon Product Advertising API

Our take #3. ZOSI 4K Ultra HD 8CH Security System

The ZOSI 4K Ultra HD 8CH Security System is a dependable 4-camera security kit that you can set up yourself in your own home or business. Like the SIMONET kit above, it uses a DVR for recording, so it requires that extra bit of set-up time.

Each camera in the kit has a 4.0mm megapixel lens and a 100-degree viewing angle which provides an excellent level of coverage. There are some nice additional features, such as the vandal-proof wire protection and durable aluminum casing on the cameras.

The app is useful, and a particularly helpful feature is the option to adjust the sensitivity for motion detection. This can help you stop getting false alarms if you find it is going off too often without reason.

  • 4K Ultra HD: Offers four times the resolution of 1080P. The ultra HD 4K CMOS Image Sensor enables more light to be captured by the camera improving color quality and performance in low-light.
  • Advanced H. 265+ video compression DVR: This system uses the highest compression technology, meaning that it consumes half the data of standard systems. This maximizes storage space, improves efficiency, but still preserves excellent video quality. USB backup.
  • Remote Access: Free Zosi smartphone app provides you with 27/4 viewing access to every one of your cameras
  • Customizable alerts for motion detection: set alerts on your smartphone and receive push notifications when unexpected movements are detected. You can customize the set area and adjust sensitivity.
  • Waterproof/weatherproof cameras so suitable for any environment
  • Four different recording modes (continuous, motion detection, manual, and schedule) to get the set-up you want
  • Remote viewing from desktop or mobile app
  • Extra security from motion detection
  • You can connect this system to a 4K TV using an HDMI cable, for optimum viewing
  • More complicated installation due to No PoE connection
  • Some users have reported that the motion sensor has limited functionality

The ZOSI 4K security camera system will provide reliable recordings of the happenings around your home. A feature I particularly liked was the different recording modes: you can quickly switch from continuous recording to scheduled or motion-only recording. This would be a useful feature for people who are often at home, and may only need the motion-only setting on a day-to-day basis, but want more footage when they go away on holiday, for example.

Some users have not found the motion sensor to be the most effective, so if you’re looking for those advanced security features, you may prefer to choose a model that has a more dependable motion detector. 

If you want a good quality 4k security camera system that offers a great amount of storage, buy the ZOSI 4K Ultra HD 8CH Security System today!

Amcrest 4K Security Camera System 8CH 8MP Video DVR with 4X 4K 8-Megapixel Indoor Outdoor...

Last update on 2021-04-15 / Affiliate links / Ratings / Images from Amazon Product Advertising API

Our take #4. Amcrest 4K Security Camera System 8CH 8MP

Like the two systems above, the Amcrest 4K Security Camera System is another system that records on a DRV. You get a huge amount of built-in storage, so this system is recommended for anyone who likes to have a hard-copy of their footage. You can further optimize the amount you can store by setting it to record only when motion is detected.

The cameras are 4K, offering a video quality of 8-megapixels. The 100 ft range night vision mode would be especially useful for those who are worried about leaving their property overnight.

The app is easy to use and offers real peace of mind when you’re away from home for long periods. It sports the additional bonus of playback, so you can re-watch events remotely if needed.

  • Excellent image quality and 100 ft of night vision.
  • 87° viewing angle: View more with the 87° viewing angle
  • Built-in 2TB hard drive: The built-in 2TB hard drive enables continuous recording over long periods and can be periodically backed up through USB. It can be set to automatically overwrite old footage when full. To extend recording time further, set it to record only motion events.
  • Remote access: Access your cameras wherever you are through the free Amcrest View app.
  • Customizable alerts: Receive push notifications when unexpected movements are detected. Set the motion zone boundaries, sensitivity levels, as well as playback.
  • Waterproof and weather-resistant cameras
  • Impressive image quality
  • Motion detection feature
  • Excellent level of storage offered by built-in hard drive
  • Remote viewing from desktop or mobile app
  • Angle-view not as wide as other systems

This offering from Amcrest is armed with all of the typical features of a decent security camera system. It has great picture quality, a large amount of built-in storage, and remote access from the compatible app. For the cameras, we were impressed with the zoom capability, and users have given particularly positive responses to the level of clarity offered in the night vision mode.

We did notice that you don’t get as wide a view with the 87-degree camera angle, so this might not be the system for you if you’re looking to cover a large area of ground with each camera. On the other hand, the smaller angle does mean that the image quality isn’t distorted as much by the fish-eye effect.

To buy this Amcrest security camera system and start protecting your home today.

Arlo VMS5240-100NAS Ultra - 4K UHD Wire-Free Security 2 Camera System

Last update on 2021-04-15 / Affiliate links / Ratings / Images from Amazon Product Advertising API

Our take #5. Arlo Technologies Ultra – 4K UHD Wire-Free

This is a 2 camera system from Arlo Technologies. It’s totally wire-free and connects to the smart hub, which makes it easy to set up. You can store all of your video and audio footage in the cloud for up to 30 days.

The cameras offer a wide 180-degree view but use automatic image correction to get rid of any distortion from the wide-angle. So, if you’re looking to cover a lot of ground with your cameras, this could be the system for you. Meanwhile, for those with a particular interest or need for overnight monitoring, the color night vision will prove a welcome and exciting addition.

If you’re looking for a system with a strong app, the Arlo Ultra camera system will make a good choice. The Arlo Smart Premier service allows you to receive instant alerts on your smartphone upon detection of motion or audio, set smart schedules, and easily find, view, and share recordings. It’s easy to personalize your experience to meet the needs of your lifestyle. It’s worth noting, though, that when you buy the Arlo Ultra 4k system, it comes with a one-year subscription to the Arlo Smart Premier service, including cloud recording, but this requires paid subscription after one year.

  • Ultra 4K and HDR wire-free system: Provides advanced image quality and enhanced night vision through a wireless 2-camera system
  • Auto-zoom and tracking capability: This camera system features auto-focus to focus on any moving object with detail and clarity
  • 2-way audio: Hear and speak to visitors without interruption with noise cancellation technology.
  • 180-degree diagonal field of view: With this ultra-wide-angle lens, you can see and protect more of your property. The lens has an auto-image correction, which reduces the fish-eye effect you often get with security cameras.
  • Simple installation due to wire-free design 
  • Compatible with Alexa and HomeKit
  • Integrated spotlight feature
  • Night vision in full color rather than black and white
  • Waterproof/weather resistant
  • Two-way audio to communicate with guests/visitors
  • Doesn’t support 4K video when using automatic zoom/track setting
  • Cameras don’t work beyond a certain distance from the smart hub
  • Additional cost to store ultra HD recordings

This is a high-quality security camera system and provides a range of exciting new features not offered by many of its competitors. Features we thought were particularly useful were the spotlight, which provides an additional method of warding off unwelcome visitors, and the two-way audio system that enables easy communication with visitors.

If you like unified technology systems, this Arlo camera system would be a great choice, as you can set it up to work with Alexa and Homekit. The app offers high levels of personalization, and it’s really easy to use. If the remote access and playback service are really important to you, and you’re happy to pay the subscription after the initial year, then we would definitely suggest this product to you.

Don’t miss out – to kit your home out with Arlo Technologies latest security system and purchase today.

Buyers Guide – Why Choose a 4K Security Camera System?

There are several advantages that a 4K system has over lower resolution camera systems. These include:

  • Better Detail: 4K systems enable you to pick out small details that you wouldn’t see with lower resolution cameras. This can be particularly useful in the even of a car-related incident, allowing you to read license plates, for example. Overall, you have a higher chance of identifying who or what is interfering with your property.
  • More Storage: Most 4K camera systems use high-quality compression technologies, meaning that you’re able to record more with less equipment. Ultimately, this means that you’ll save on the amount you have to pay out for additional external storage or cloud-based storage.
  • Enhanced Night Vision: With anything below 4K image resolution it’s hard to make out much detail in night vision. 4K lenses are able to capture much more detail in the dark, which, as many crimes and intrusions happen at night, is a real benefit.

What Should I Look For in a 4k CCTV System?

When you’re on the market for a new CCTV security system for your home or business, there are several things you should take into account before making a purchase. Thinking about these factors can help guide your search and find the best 4K system for you.

Security camera

Number of Cameras


It’s essential to consider the number of cameras you’ll need to give you comprehensive coverage. Therefore, you should start by asking whether you need a single camera, a full system, or something in between. If you only need a single camera, there’s no point in buying an entire 4-camera kit. Some, such as the Arlo Ultra, offers two cameras with wide-angles, which may provide a happy medium.

Video output in a Control Room

Video Output Method


You’ll need to consider how you want to view the video playback and where the video footage is sent. There is a range of options on the market, and it depends on what you’re looking for.

If you choose either NVR or DVR models, they come with an entire monitoring system that receives the video and allows you to view it on a television or monitor. This is a simple and reliable system.

Many models also offer linked apps (some free, some subscription-based) that allow you to access your cameras from your mobile or tablet. This would be a sensible choice if you’re frequently away from home and want to check-in. The level of app quality and the features offered vary significantly from product to product, so do make sure you have a look at what’s available if this is important to you.

Set-up Process


The set-up process can be a deal-breaker for some consumers. Wired systems often take a longer time to install, but are equally as good once set up. On the other hand, if you want to avoid long set-up times, consider plug-and-play systems. For these power over ethernet (PoE) systems, all you need to do is plug in an ethernet cable for it to work.


Which is the Best 4k Security Camera System for Me?

In short, the best 4K surveillance system for you depends on what your priorities are and where your preference lie. You should consider the size of your home and how many cameras you’ll realistically need; the kind of technology you want to use (wired or wire-free); how much storage you’ll need; how much you can afford to spend. To make it easier for you, here we’re offering our best recommendations from the above guide for different scenarios:

  • If you’re new to home security systems and want a quick and easy set-up process, the Reolink RLK8-800B4 4K PoE Security Camera System would be a good option. It’s ready to go with a PoE system, and you get great-quality footage.
  • If you want the latest tech and are happy to pay additional costs for all the latest features, the Arlo Technologies Ultra – 4K UHD Wire-Free will suit you well. You only get two cameras, but they offer a really wide-angle view. This is also a great choice for anyone who wants color night vision.
  • The Amcrest 4K Security Camera System is a solid and dependable kit, offering a range of excellent features at a good price. This would suit anyone looking for a high-quality system with a lot of storage and remote access.

In Conclusion

This review has outlined what we think are five of the very best options for Ultra HD security cameras for homes and businesses. The one you choose ultimately depends on practical factors, such as your property size, requirements for storage, and budget, as well as personal preferences on the features offered by each system.

All the camera systems listed in this review are high quality, have an amazing array of features, and stand up to scrutiny. We think that going for 4K is worth it since you get such high-quality images and improved night vision. Furthermore, technology is moving forward, and 4K is likely going to become the most common video resolution, so you’ll be up-to-date and ready for any tech upgrades in the future.

Don’t wait any longer, and start protecting your home today with a 4K camera security system.

FAQs for HD Security Cameras

a man standing with a question mark board that ask if he should get a 4k CCTV

For an image to be classified as 4K Ultra HD, it must be at least 8 megapixels.

IP stands for internet protocol, and means that image data via the internet, rather than the local recording devices that CCTV cameras depend on. They record in higher resolution and are widely used for security cameras.

Wired systems need connecting to a DVR or NVR recorder, while wire-free systems don’t have any cables at all. Instead, they transmit and store the security footage on the cloud.

4K offers the highest resolution for home security cameras, and this is particularly evident in night mode settings. 4K also provides the best option for zooming in.

A frame rate of over 24 FPS will be a smooth recording to the naked eye. Security cameras go all the way up to 60 FPS, but it’s not a necessity unless you’re going to regularly need to slow down and playback footage.
