What Should You Consider When Choosing the Best 4K Security Cameras?

4K Ultra HD IP cameras are fantastic, but it’s crucial to ensure that you’re getting a true 4K or 8MP security camera, whether you’re seeking a dome, bullet, wireless, PoE, PTZ, night vision, or audio-enabled model.

Here are a few things to check to avoid being duped by marketers:

1. 8MP Security Camera Resolution

When it comes to 4K IP security camera resolution, it might seem like a no-brainer. After all, isn’t it 4K, as advertised?

Unfortunately, some security cameras may tout their 4K sensors to grab your attention, only to provide you with grainy 1080p video images. Be sure to check the resolution (3840*2160) to ensure that you’re getting a genuine 4K Ultra HD security camera.

2. 4K Surveillance Camera Codec

A high-quality 4K security camera will come equipped with advanced High-Efficiency Video Coding (HEVC), also known as H.265. This technology keeps file sizes low while preserving the crisp image quality of 4K video.

Essentially, it allows the 4K camera to deliver 8MP high-quality videos without putting undue strain on your home network. Additionally, it saves storage space by half, which is of exceptional importance for 4K security camera systems.

3. 2160p Security Camera Lens

Attention: not all 8MP security camera sensors deliver high-quality video. In some cases, the video quality of 4K CCTV cameras is limited by the quality of the lens rather than the resolution of the sensor.

A genuine 4K surveillance camera is equipped with high-quality lenses that can capture more in the frame with greater clarity. The focal length of the 4K IP camera lens is also relevant, with wide-angle lenses being more suitable for covering distant areas. If your priority is to record car license plates, a lens with a longer focal length, specifically pointed towards the road or driveway, is more appropriate.

4. 4K IP Security Camera Viewing Angle

Although a 4K security camera offers a wider range of view, it’s still important to check its viewing angle to ensure that the 4K IP CCTV camera covers your desired monitoring area, such as the front door, driveway, porch, or garage.

Typically, a 4K video security camera offers around 100° of horizontal coverage. If you need to cover more areas, such as with 360° endless monitoring, consider a 4K HD security camera with PTZ function.

5. 4K Security Camera Performances in Adverse Conditions

It’s important to note that not all 4K IP security cameras can truly provide high-quality images, especially in adverse conditions.

For instance, you may have noticed that some 8MP or 2160p security cameras capture images where one part is extremely dark while another is so bright that details are obscured.

To address this issue, consider getting WDR security cameras. Learn more about WDR and its benefits here.

6. 8MP Surveillance Camera Video Fluency

Have you encountered the abbreviation FPS on a product page or forum while researching 4K IP security cameras? If so, you may be wondering what 4K security camera 30FPS means.

Pay attention, as FPS (frames per second) has a significant impact on video fluency.

Generally speaking, a 4K security camera with 30FPS or 20FPS can record fluent video. If possible, consider requesting a video demo from the manufacturer or searching for 8MP test video footage from other users on YouTube to assess video fluency.

7. 8MP Security Cameras Night Vision

While 4K security cameras offer brilliant image quality during the daytime, with clear images, vivid colors, and great performance even in glare, this is not enough. Night vision is an entirely different matter. 4K or 2160p cameras have more to contend with in low light conditions, such as noise problems and balancing brightness.

Some 4K night vision security cameras use 3D DNR technology to achieve the best long-range night vision. Don’t forget to check the night vision video during your research, after admiring the excellent 8MP daytime images.

For superior night vision, consider starlight cameras.

Note that while some 4K night vision cameras claim to offer color night vision, it may not work as expected, as ambient light is required for color night vision. In total darkness, these cameras will still switch to black and white night vision.

8. 4K CCTV Camera Support

A perfect camera is only as good as its responsive support team. I’ve seen many 4K CCTV camera users spend considerable time and effort troubleshooting their 4K IP security camera problems in forums.

Instead, why not choose a 4K surveillance camera manufacturer with a reliable support team from the outset? Some camera producers, such as ZOSI, promise one-on-one support to guide you through installation and assist with any issues that may arise.

Additionally, if you have time, consider reading 4K security camera reviews to learn what real users like and dislike about 8MP security cameras.

9. 8MP Security Camera Warranty Time

Warranty is an important but often overlooked consideration, especially when purchasing from retailers or camera agents. A one-year warranty provides added value to the 8MP security camera.

Some people unknowingly purchase brand new security cameras from agents, only to find that the warranty time has already been halved. The safest course of action is to buy 8MP cameras directly from the manufacturer on official website to ensure the full warranty period.

10. 4K Security Camera Compatibility Issues

To avoid compatibility issues, ask yourself the following two questions when selecting a 4K CCTV camera:

1. Is the 4K IP CCTV camera compatible with innovative apps, such as ZOSI App, to utilize its full range of functions?
2. Will it have to be used with third-party software that provides limited access to camera features?
