What is A 4K Security Camera System?

Surveillance cameras feature different abilities to record objects. For a 4K Ultra HD model, it has an 8MP sensor that often delivers sharp and crystal images. The native image resolution of the sensor is 3840 x 2160 pixels.

By simple calculations, this is equal to 8,294,400 pixels.

If you fancy playing with numbers, it means the image quality is about four times more superior to 1080p Full HD. And about 1.6 clearer to that of 2K QHD [5MP].

Usually, the majority of people use 8MP surveillance cameras when they want to monitor large areas. This is so as on top of crisp pictures, it comes with a wider field of vision.

Despite its stunning abilities, however, a 4K CCTV cost higher than other lower-resolution devices. As such, you need to have a significant budget to enjoy the very best from your system.

NB: A 4K Ultra HD footage is entirely different from that of Disney’s movies. In video surveillance technology, the term represents a resolution that is clearer and richer in quality than Full HD and QHD. As you buy a 4k CCTV, therefore, don’t expect the displayed images to be as sharp as those from the movies.

Is A 4k Security Camera System With Audio Worth It To Have?

A simple answer to this question is a solid Yes. Why?

For one, a 4k surveillance cam records high-quality images that are very rich in detail and clarity. As such, you can even monitor a large scene without degrading the necessary image details. In fact, an 8MP image sensor can accurately identify a license plate of a car located up to 75 feet under good conditions. This is excellently spectacular as it’s more than double the range of a 1080p Full HD

Besides helping monitor a large scene, the other benefits of a 4k security camera include:

The CCTV can lead to faster processing of investigation, plus recovery of your stolen items since they deliver pictures that are richer in detail. You have the advantage to know what is happening around your properties at any time. It can help increase the value of your properties. Just like with the others, the security camera can help deter crime when the potential burglar notices its presence.

You can enjoy discounted rates from your insurance company since you have minimized the risk of vandalism and burglary. With a surveillance cam that has the 2-way audio, you can connect with your kids and other family members while even miles away. Also, the video surveillance system can help improve your workforce performance since they have the illusion that you’re watching them.

Although they may seem straightforward, these benefits are not with all the 4K surveillance cameras. Therefore, you have to be real careful while doing the selection. Otherwise, you might end up thinking GetLockers lied to you, yet the system you pick is what has failed.

Before we look at what you should consider while choosing the best 4k security camera system with audio, here is a selection to get you started.

For instance, to monitor your home, a simple surveillance system like the Arlo Ultra can work out for your small space. However, if you manage an industrial warehouse, an expandable Surveillance kit is the best. It allows you to can connect with multiple security cameras to place at different positions of your scene.

Available Budget

After determining your needs, have a check on your budget. It’s crucial and the biggest determinant of how successful your plans will work.

Following its superior image sensor and the technologies to support it, a 4K Ultra HD security camera tends to cost more. Therefore, if you have a tighter budget but still you need a higher resolution system, you ought to be very careful with the offer on the table.

Otherwise, you might end buying a cheap 4k system that is only aimed to serve you for a month at most.
As for the best budget-friendly model on our list, its creators [OOSSXX] has optimized the cameras’ features. They have included 5MP cameras to ensure you can still have vivid recordings until you can afford 8MP quality models.

Field Of View And Detection Range

Usually, the field of view is directly proportional to the image resolution. This explains why the majority of 4K systems that we have reviewed have a high viewing angle.

Even so, you still have to consider the range in regards to your needs. If you are hoping to monitor a large area, for instance, you should go for an Ultra HD CCTV system that has a wide viewing angle.

Also, important areas like the parking lot, warehouses, driveways, or front yards will need a system with a long detection range. This is to ensure you can see the person coming towards your compound while still from a distance.

Night Vision

On its end, the function helps ensure you can monitor your properties at all times of the day. Whether it’s during the day or at night when there is low visibility due to the present darkness.

If your budget allows, we would recommend you choose a system that has a long-range infrared and colored night vision. With such a system, no shadow will ever be left undetected and even there is the advantage of getting clearer images.

As you will come to notice, the colored night images are usually richer in detail than the usual black and white.


Unlike the lower quality images, the higher resolutions tend to encompass more pixels, which can take up more storage space.

As such, choose a 4K security camera system that has a larger [local] storage since it can hold more videos before it’s full. It’s even crucial you consider a higher video compression codec, such as H.265 as it can lower the image bit-rate.

Thereby maximizing the storage consumption by over 50%.

While looking for larger storage and higher compression, by the way, don’t forget you won’t always be there to be formatting your HDD. Therefore, check for a system that supports loop recording to ensure it can auto overwrite the oldest files. And then, ensure you never miss any current happenings around your property.

Setup And Installation

Of course, nothing is so thrilling like a device that you can set up and use on your own. It means you won’t need to get back into your pockets and hire a technician to install your system. Also, it means you will save on time that you might have wasted waiting for the technician to come.

Luckily, all the six systems on our list are either wireless or wired with PoE technology. As such, everything is plug-and-play, with the only hard work been standing on the ladder as you mount the camera.

Last but not least, we’d recommend you choose a 4K video surveillance system that is weatherproof certified. This will ensure your cameras can stand on the rain, snow, and extreme sunshine without damage. In the end, the system will serve you for a long time, with lesser maintenance and lower service costs.
