Basics of 5MP And 4K
When deciding between 5MP and 4K security cameras, it&#;s a good idea to start with a good understanding of camera resolutions.
What is 5MP?
5MP resolution stands for the image quality of 5 megapixels. It&#;s an indication of the number of pixels a camera can capture in an image.
In the context of security cameras, a 5MP camera captures images that have a resolution of x pixels and are composed of 5 million pixels. Increased pixel count provides sharper images, making it easier to identify objects, faces, and other important details.
4K refers to a specific resolution standard that provides exceptional image quality and clarity. Also known as Ultra HD (UHD), represents a significant advance in visual technology.
In the context of security cameras, a 4K camera captures video footage at a resolution of x pixels, composed of 8.3 million pixels. This superior image quality is particularly advantageous when capturing fine details of large areas, expansive outdoor spaces, or locations that require long-range monitoring.
5MP vs. 4K: Comparison Table
The key difference between 4K and 5MP lies in their pixel count: 4K offers approximately 8.3 megapixels ( x pixels) and 5MP provides 5 megapixels ( x pixels), with 4K resolution having a better image quality and greater detail.
The chart below provides an at-a-glance summary of the differences between 5MP and 4K:

Note:
PPF is used to calculate the number of pixels per unit of measurement in the camera's field of view(FOV). The calculation formula is: PPF= horizontal resolution/ field of view.
To ensure accurate identification for facial and license plate recognition, it is widely advised by experts that the minimum measurement should be at least 40 Pixels Per Field (PPF).
Choosing Between 5MP And 4K Security Cameras
When choosing between 5MP and 4K security cameras, the following five elements are the most important.
Bandwidth
4K and 5MP security cameras have different bandwidth requirements based on their different compression standards.
4K security cameras with H.264 compression typically require higher bandwidth, (from approximately 10 to 20 Mbps) than 5MP cameras (from 2 to 8 Mbps) due to their increased resolution.
4K security cameras with the more advanced H.265 compression consume significantly less bandwidth than H.264, ranging from approximately 5 to 10 Mbps. Similarly, 5MP cameras using H.265 compression consume less bandwidth than H.264, ranging from around 1 to 4 Mbps.
Budget
Costs of 4K and 5MP security cameras vary depending on several factors, but 4k cameras are generally more expensive. Taking Reolink as an example, an entry-level 5MP camera such as the RLC-510A can be purchased for $50. A mid-to-high-end 5MP camera with PTZ and night color vision such as E1 Outdoor. Can be purchased for $100.
4K camera costs vary widely. 4K PoE camera without PTZ function like the RLC-810A costs less than $80. However, a wireless 4K camera with zoom and other advanced features such as the Argus PT Ultra costs less than $200.
Storage capacity
The storage required for 4K and 5MP security cameras depends on multiple factors, including bitrate, resolution, fps, and more. The information below can guide you through calculating the memory used by each camera&#;s mainstream and substream:
Generally, a 5MP camera's mainstream bitrate is 6 Mbps and its substream bitrate is 2 Mbps. To calculate:
Storage usage per mintute (mainstream) = 6 Mbps x 60 seconds / 8 bits = 45 Mbps
Storage usage per mintute (substream) = 2 Mbps × 60 seconds / 8 bits = 15 Mbps
4K camera's mainstream bitrate is 8 Mbps and its substream bitrate is 2 Mbps. To calculate:
Storage usage per mintute (mainstream) = 8 Mbps × 60 seconds / 8 bits = 60 Mbps
Storage usage per minute (substream) = 2 Mbps × 60 seconds / 8 bits = 15 Mbps
Field of view
With their high resolution, wide-angle lenses, and millions of pixels captured in a single image, 4K cameras provide a significantly wider field of view. Capturing the same, wide coverage area with a 5MP camera would produce blurry edges, and physical features, license plates, and other important details would not be identifiable.
Night vision
4K security cameras have image sensors and processing technology that lets them capture much clearer images at night than 5MP cameras.

Exploring 4K Resolution Comparisons
When it comes to choosing the right resolution for your display or camera, it's essential to understand the differences between various 4K options. These links provide valuable insights into different 4K resolution comparisons:
These resources will help you make an informed decision when selecting the 4K resolution that suits your specific requirements.
FAQs
1. Is 4K better than 5MP?
4K is generally considered better than 5MP in terms of video or image quality, but factors including color accuracy, dynamic range, contrast, and overall image processing are also important.
2. How many MP does a 4K camera have?
Multiplying the horizontal and vertical pixel counts gives you total pixel count, so the calculation would be:
pixels × pixels = 8,294,400 pixels
Divide the total pixel count by 1 million to get the megapixel count of 8.29 megapixels.
3. Is 5MP considered high resolution?
5MP resolution is considered a moderate resolution by today's standards. It offers a respectable level of detail for applications like digital photography, printing, or displaying images on screens, but it will not provide the level of detail or resolution provided by higher-end cameras or newer devices featuring higher megapixel counts.
High resolution professional cameras generally offer resolutions ranging from 20MP to 50MP and beyond, letting photographers capture more intricate details, but for everyday photography or displaying images on standard screens, 5MP will provide satisfactory results.
4. Is 5MP the same as p?
No. 5MP refers to a camera resolution of approximately 5 megapixels, and it provides more detail and higher resolution than p, which refers to a video resolution of pixels × pixels. P is a standard high-definition (HD) resolution, but 5MP offers a higher pixel count and superior image quality than p.
Conclusion
When deciding between a 5MP or 4K security camera, choose wisely and invest in the one that matches your needs and provides the detail and image quality necessary to protect your property and assets.
If you have other questions or comments regarding 5MP or 4K security cameras, leave your comment below!
I recently performed the following test to compare CCTV video surveillance recorded using a p vs 5mp security camera. You can watch the video results here.
These are the two bullet-style surveillance cameras that I used for the comparison test. The one on the left is a BPRO-OL952 p camera and on the right is this 5mp-BL52 5 megapixel security camera (which is basically a 5mp version of the original BPRO-OL952). The cameras look almost identical. Both of the bullet security cameras have a 3.6mm fixed lens, however, the 5mp version gives a slightly wider angle of view because it has a larger image sensor. Both are HD-over-Coax BNC cameras which means that they support multiple video formats (AHD, HD-TVI, HD-CVI, and analog CCTV / CVBS). The testing results are expected to be the same if I would have used IP cameras instead of HD CCTV cameras.
The BPRO-OL952 supports p / 2 megapixel resolution in AHD, HD-TVI, and HD-CVI video modes.
The 5MP-BL52 supports 5 megapixel and 4 megapixel resolutions in AHD, HD-TVI, and HD-CVI video modes.
Hybrid CCTV DVR
Both cameras were set to AHD (analog high definition) video mode and hard wired to an hybrid CCTV / HD security camera DVR using RG59 Siamese coax cable. **Please note that at the time the above video was made, we were supplying iDVR-PRO DVRs. CCTV Camera Pros is now recommending our best selling Viewtron 4K security camera DVRs (pictured above). The BPRO-OL952 was set to p (2mp resolution) and the 5MP-BL52 was set to 5mp resolution. The iDVR-PRO DVR that we used at the time of the test was able to record at p and 5mp resolution.
The DVR supports 4k resolution video output via its HDMI output. This means that p and 5mp cameras can be displayed at 4K resolution on the monitor that is connected to the DVR. The image is simply stretched to meet the resolution of the connected monitor. The HD video that I created and the screenshots that you see below were all captured at 4K resolution from the DVR&#;s HDMI video output.

Here is another side-by-side comparison of the 5mp vs p CCTV camera resolution with 3x digital zoom. Please click on the above image or on this link to view the 4K resolution images of the license plate comparison.
In this test, the camera is focused on a license plate that is 20 feet away from where the cameras are mounted. Please note that these bullet cameras are not true license plate recognition cameras. I am using the license plate in this example because the letters on the plate make it convenient to compare the video clarity at different resolutions. You can visit this page if you are interested in learning more about true LPR cameras.
Observations and Summary
You can see in the above video surveillance demo and snapshot images that a 5mp security camera captures video clearer than a p camera. This was obviously expected. However, the difference is not as big as I expected. Considering that a 5 megapixel camera is 2.5 times the resolution of a p camera, I was expecting the difference to be more drastic. When you are designing a video surveillance system for a project, you must consider additional factors such as the additional disk storage that is required for 5mp video recording vs p. Yes, hard drives are much cheaper nowadays but it is still a cost and a trade-off.
At the time of this writing (October of ), CCTV Camera Pros is still selling many more p (2 megapixel cameras) than we are 5 megapixel. 5 megapixel is gaining more momentum but p is still the most popular right now as it seems to be a good balance of video quality and economical storage cost.
Another consideration is that 5 megapixel resolution is not 16:9 aspect ratio, it is 5:4 aspect ratio. On a typical HD TV or monitor, the video image will be stretched to fill the screen. This is because most monitors and TVs are 16:9 aspect ratio.
You will notice this in the above side by side comparison that is zoomed in on my face. My face is wider and more round in the 5mp image because the image is stretched. The more oval thin headshot captured by the 2mp camera is a more accurate representation of the real me.
Last, the hybrid 5mp security cameras that we supply also work in 4mp resolution which is 16:9 aspect ratio. And, Viewtron surveillance DVRs also support 4mp CCTV cameras and 4K CCTV cameras. So, for customers that want to go higher than p resolution but do not like the way 5 megapixel resolution is stretched, 4 megapixel may be a good compromise. I plan on comparing p vs 4mp in another post.
For now, we will continue to educate customers on the difference between resolution quality so that they can make an informed decision. I suspect that p HD security cameras will be used in video surveillance systems for a long time.
