Quick Pick: Top 5 Best 4K Security Camera Systems

If you can’t decide which 4K security camera system is the best or you don’t have time to do thorough research, we’ve listed the top 4K security camera systems. Our quick picks are listed below.

The PROs of having a 4K security camera system

The most important question when researching for a 4K security camera system is “Why should you choose a 4K surveillance system in the first place?” Below we’ve listed the advantages of having a 4K surveillance system.

1. Clearer images

That’s the most important advantage of getting 4K security cameras. They offer a 4K resolution (8MP) which is 4 times higher than a 1080P camera (2MP).

An 8MP security camera with a lens of 3.6 or 4mm offers a clearer image that is able to capture sharp objects at a farther distance than regular cameras. That’s the whole point of a security system: providing high-resolution images. The 4K surveillance system achieves that properly.

2. Wide viewing angle

A 4K security camera has a wider field of view compared to regular 1080P cameras, meaning you can get more details on the sides of the picture. The wider the field of view, the more area is covered.

The viewing angle depends on the lens size as well. A 2.8 mm lens is wider than e 3.6 mm. Usually, a 3.6 mm offers a 110 degrees viewing angle, and 4 mm is almost 100 degrees. Either way, using a 4K camera you can monitor wider areas and you won’t lose any details.

This comes in handy because you can utilize fewer cameras to secure your area which lowers the overall cost of your security system. You get better value for your investment.

3. Digital zooming

All these 4K security camera systems listed here offer digital zooming, meaning you can digitally zoom the picture and get a clear picture of an object or person.

This zooming feature can be used both on the live stream mode as well as on the playback mode. On a regular camera, you can’t really zoom anything because the image will get pixelated/blurry right away. But on a 4K security camera (8MP resolution) that’s not the case, the picture will still be clear.

You can zoom directly in the recorder via the 4K TV or you can even remotely zoom on the phone app or tablet. It’s a useful feature that may come in handy if you need to ID certain people or objects.

4. New CCTV technology

4K cameras are becoming the new standard on CCTV security systems. Long gone are the days where having a 720p or 1080p camera was the norm, nowadays everyone is going for 4K (8MP cameras). Why would you spend money on an obsolete system when the price difference with a 4K system is non-considerable?

Since the 4K security systems are becoming more popular and the norm, it makes sense to choose such a system for your home or business facility. We think the price difference (2MP vs 8MP) is worth the money.

Factors to consider before buying a 4K Security Camera System

In this section, we will list a few factors that you need to consider before purchasing a 4K Security Camera Systems. You should prioritize to get the basic features that fit for your home or business project.

Camera’s resolution

A higher resolution means a clearer picture. That’s what most people want, they want to have a clear CCTV image that makes it easy to identify objects or people.

4K cameras offer 8MP resolution, however, many sellers try to trick by using the keyword “4K” and selling 1080P cameras instead. Keep in mind, a 4K/8MP has a resolution of 3840×2160, always check the settings and ensure the resolution dimensions are correct.

Get the right lens size

Lens size is what determines the security camera’s viewing angle. This angle is quite important, the wider the angle, the more area is covered but fewer details after a certain distance. A narrow viewing angle means fewer areas covered but you can see more details (clearer).

Generally speaking, the security cameras come in 2.8mm, 3.6mm, 4mm, and 6mm. So, 4K security cameras have a viewing angle from 90 degrees to 115 degrees.

Night Vision

Night vision is a very important part of any security camera system because most of the crime happens during night time. That’s why you need to get cameras that have clear night vision.

As you can see, 4K security cameras have a great image quality in the daytime even when there’s glare. But night time is a different thing.

For night time the cameras need to have strong IR LED lights to illuminate the area under surveillance. These lights are visible to the camera only and don’t cause light pollution. 4K security cameras have more capability to work with darkness issues such as noise or balance of light.

Moreover, these advanced 4K security cameras often come with 3D DNR technology which is used to enhance the long-range night vision capability. Sometimes, certain cameras that use starlight technology can provide color night vision.

Compression Codec

A true 4K security camera system supports the latest surveillance codec which is H.265+. Using this compression algorithm, the system is able to reduce the videos’ file size without compromising the image quality. So the picture is still clear, but it takes less space on the hard drive.

Another perk of H.265 codecs consists of using less bandwidth on your local network. This will make the system run smoother and reduce the overall traffic on your network.

Frame Rate

Frames per second (FPS) is a crucial factor to consider before purchasing any 4K security camera system. The higher the frames per second, the smoother the live view and recording will be.

Usually, anything above 15 FPS is considered good in a security system. If the frames per second drop under 10 fps/s, the picture will look choppy and sort of freezing. The movement will be robotic.

Before buying any 4K system, check the frame rate supported by each camera. We recommend getting a system that runs 15-30 FPS per each camera. You should avoid anything less.

Go for a well-known company

Avoid obscure CCTV companies, it’s always recommended to buy from well-known manufacturers. They’re able to support the product, release firmware, maintain their phone apps, and overall provide a better product.

Additionally, you should check the warranty provided by the manufacturer. The longer the warranty, the better the system. Would you spend money on a security system with a simple 6 months warranty? Absolutely not. The warranty should be at least 2-3 years.

Common Questions about 4K Security Camera Systems

How much space do you need for a 4K security camera system

4K security cameras are considered “heavy”, meaning since the picture quality is exceptional it requires a lot of space to have the 4K videos stored.

The size of the recordings depends on a few factors such as the resolution, the frame rate, the bit rate, the recording mode, etc. The higher the bit rate and the frame rate, the bigger the recording’s file size.

However, the good news is that the hard drive prices have gone down and you add a lot of hard drives to your recorder at an affordable price. For example, the surveillance rated hard drives listed here come from 1TB to 10TB and cost between $50 to $150 each. You can install the hard drive yourself or you can get a recorder that comes with a pre-installed hard drive.
All the 4K security systems support continuous or motion recording. As a rule, motion detection recording saves a lot of space on the hard drive (50-70%), the system records only if there’s motion detected. If you set the system to motion, you can double the numbers of recording days.

Just to run some numbers, a security system with 8 cameras and an 8TB hard drive, can record up to two months and double (4 mo) if you set the system to motion detection mode.

Which cameras are better: 4K or 5MP?

As we mentioned, 4K is another way of saying 8MP. So obviously a 4K (8MP) camera is better than a 5MP security camera. The resolution of a 5MP camera is almost half compared to a 4K camera.

This doesn’t mean that the 5MP are not good, they’re pretty good, especially for indoor installations. However, you get away with a better picture and much more details by using 4K camera systems. Moreover, the price difference is negligent, simply go for a 4K system. It’s worth the extra money.

What’s the cost to install a 4K security camera system?

It all depends on the number and type of cameras. Usually fewer cameras, the higher the installation price. However, all the systems listed here are easy to install and are definitely DIY projects. You don’t even need any network skills, simply run the wires, plug the camera, and pretty much that’s it.

If you hire an installer, the installation charges are around $150-$250 per camera run. Once they are done, they can help you install the system on the phone as well so you can live view any time.

What is the best monitor for 4K security camera systems?

To get the best out of your 4K security camera system you MUST use a 4K monitor. If your TV/monitor is 720p, don’t blame the security camera system for the poor image. The system needs to have the right monitor to display 4K images.

We recommend going for an LED or LCD 4K TV monitor for watching the live view or recordings from a 4K security camera system. A few options can be found on this link.
