The race for megapixels from digital photography has gradually moved to IP video surveillance. Our customers are increasingly asking for cameras 3, 4, 5 megapixel and even higher. Most of them are absolutely sure that the higher the resolution, the more megapixels the camera has, the better it will show, the higher the detail of the frame will be. Manufacturers to please consumers are releasing cameras with high resolution, 12 megapixel IP cameras, now fashionable in 4K format, are already being sold with might and main.

We decided to find out - does the video quality of IP cameras really increase with the increase in megapixels? Is it worth overpaying for high resolution cameras, NVR processing power, high network bandwidth, and terabytes of storage required for such a high resolution. We have selected several cameras from the warehouse with different resolutions - from 1 to 5 megapixels. We also ordered several expensive 5 - 8 MP IP cameras from manufacturers for this test. This is who came to our test.

We gave preference to outdoor IP cameras with a fixed lens, because they do not need to be adjusted and flaws in the tedious adjustment of varifocal lenses will not affect the quality of the video image. True, we did not find 5-megapixel cameras with a fixed lens and tested 5-megapixel variofocal cameras. We installed all the cameras in the same place and pointed to the opposite wall, where we have several homemade "test charts" hanging.

Let's see what we got. All snapshots were taken through the web interface of the cameras using the IE browser and the ability to save a snapshot built into each camera. In the following table, we have placed a reduced frame to a resolution of 640x480 (or 640 by 360, if the camera has a widescreen matrix with an aspect ratio of 16: 9), as well as a crop (cut out of the frame) with a resolution of 200x360 pixels. It more clearly shows the quality of the "drawing" of small details of the image - in particular, the letters on the Sivtsev table (a table for testing eyesight).

To view a full-size frame from an IP camera, click on its thumbnail copy in the table.

What we noticed when comparing these frames:

1. Cameras have different aspect ratios. IP cameras with a resolution of 1, 2, 4 megapixels have a widescreen frame with a ratio of 16: 9. And cameras with a resolution of 1.3, 3 and 5 megapixels - 4: 3. Those. the latter have a greater vertical viewing angle. This is very important for those cameras that will "look" at an angle from top to bottom on the object. For such cameras, there will be fewer dead zones under the camera, both near and far. It is interesting to note that the 3MP camera in relation to the 4MP camera not only has a greater vertical viewing angle, but also has a resolution: 1536 versus 1440 pixels.
2. Cameras have different viewing angles, and it depends not only on the lens, but also on the size of the matrix. Budget IP cameras with a 1/4 matrix and a standard 3.6mm lens have a horizontal viewing angle of no more than 60 °. But the 5MP IPEYE camera with a 1 / 2.5 matrix has a wide viewing angle both vertically and horizontally (more than 110 °). True, there the lens in the shortest focus has a distance of 2.8 mm.
3. Well, and the most important thing we wanted to pay close attention to was the permission. If you carefully examine all the frames, you will notice that, undoubtedly, as the resolution (megapixels) increases, the detail increases. But NOT PROPORTIONALLY! Not colossal. A 4MP camera in relation to a 2MP camera does not double the picture. Detail increases insignificantly... In any case, not a single camera could "cope" with the second line from the bottom of Sivtsev's table. And already the 6th bottom line (the right letters "BK Y") confidently "read" both cameras with a resolution of 4 and 2 MP.

Of course, here you need to make an allowance for a different viewing angle. Indeed, with an increase in the viewing angle, we seem to move away from the scene being shot and the detailing deteriorates. This is especially true for a 5-megapixel IPEYE camera - the combination of a matrix and a lens gives too wide a viewing angle. And if you make the angle on it the same as for 2MP cameras (about 90 °), then the letters of this table will be read more confidently.

Interestingly, another 5MP IP camera with the same declared parameters (2.8-11 lens, 1 / 2.5 matrix) had a slightly narrower viewing angle in the shortest focus than the IPEYE-3802VP. Detailing is approximately at the same level, the picture is somewhat noisier in the dark areas of the frame, although the cost of the BEWARD camera is several times higher. But she has a motorized lens and you can control the viewing angle while sitting in front of a computer. A picture with a maximum focus of 11 mm will then look like this:

Maybe someone needs it, given that every time the focus of the lens is changed, you need to either manually or by pressing the "autofocus" button to adjust the sharpness of the image. And it takes 5 to 20 seconds. But here you can confidently read the second line from the bottom of the eye examination table.

Later, we tested a pair of 2-megapixel IP cameras with a 2.8 - 12mm varifocal lens. there is an opinion that they show better than "fixes". Here's what we got:

As you can see, the result is not much different from the previous one. The detail is almost the same as that of 2MP IP cameras with a fixed lens. Even for an expensive 2-megapixel (!) Hikvision camera (retail price of which in February 2016 was 21,990 rubles) with a viewing angle of 50 degrees set at the factory (and in order to change it, we had to open the camera, which we categorically did not want) the readability of Sivtsev's table turned out to be no more than 5 lines from the bottom.

Perhaps varifocal lenses have a higher light sensitivity and IP cameras with them "see" better in the dark, but this is a topic for a completely different test and another article, which we may refer to later. But varifocal lenses have practically no effect on the resolution. Moreover, the slightest inaccuracy in focusing can lead to disastrous results, and all megapixels will be useless. And whoever has ever set up a variofocal lens on an IP camera will agree with me that it is oh, how difficult it is, given the delay with which the signal from the camera comes to the monitor.

This is the first camera with a 1 / 1.8 sensor size that came into our hands. In addition, this camera is capable of delivering a stream at a speed of 25 fps at a 5-megapixel resolution (2592x1920 px). Others cannot do this yet. The maximum they are capable of is 12-15 fps at maximum resolution. The wide angle of view of this camera is immediately evident. At 3.6mm focus, it is wider than 5MP 1 / 2.5 cameras with 2.8mm focus. The resolution of the BSP Security camera is on par with other 5MP cameras, even a little sharper. At least the contrast of the picture is higher. However, the situation is slightly overshadowed by the blurring of the left side of the frame. Perhaps we were unlucky and came across a camera with a slightly skewed matrix.

And finally, 4K IP cameras with a resolution of 8MP came to our warehouse. It is a hemisphere with DAHUA DH-IPC-HDW-4830EMP-AS fixed lens. Here's a shot from that camera:

To open a frame at full resolution, in the browser, right-click on the picture and select the "open image" menu item.

We did not stop our test with office pictures, we also wanted to see real footage of a street scene. To do this, we directed the lenses of our cameras to the nearest parking lot, visible from our window. We did it deliberately in rather difficult light conditions - early twilight. Here's what we got.

Perhaps we chose a still too bright part of the day (17.10 - 18.00 in February), but all cameras coped with this kind of lighting perfectly. True, the 1.3 MP MT-CW960IP20 camera turned out to be slightly darker than the others, which is rather strange, because 1/3 matrix should have better light sensitivity in relation to 1/4 matrix.

As for the detail of the picture, the situation is similar to the test results in the office. Although it increases with the increase in megapixels, it does not significantly increase. Renault's license plate was read by both 4 and 2 megapixel cameras. True last Little worse.

IP cameras with a resolution of 1.3, 4 and 5 megapixels with their wide viewing angle "saw" even the number of our van, on which we carry all these IP cameras)). And the 5MP camera even saw a car parked to the left of the van. The viewing angle is amazing!

In March, we received two more 5-megapixel IP cameras BEWARD and BSP Security for testing. Let's compare how they show on the street.

5 megapixels IP camera:, resolution 2592x1944, matrix 1 / 2.5, zoom lens 2.8 - 11 mm
5 megapixels IP camera: BSP Security, resolution 2592 * 1920, matrix 1 / 1.8, lens 3.6 - 11 mm

The cameras were tested at the same time (18:00 mid-March). It is interesting to note that although the BSP Security camera has a wider angle, it has slightly better detail. State the number for the blue Ford can almost be read, which cannot be done on the frame from the BEWARD camera. Affected by the size of the matrix - 1 / 1.8 versus 1 / 2.5.

What conclusion can we make?

1. The treacherous pursuit of megapixels is practically useless and only manufacturers play into their hands (well, what a sin - we, the sellers of these IP cameras, recorders and hard drives) get more profit from them.
2. In the overwhelming majority of cases, 1-, 2-megapixel IP cameras are sufficient. And if you need better detailing of distant objects, then you need to solve such a problem not by mindlessly increasing megapixels, but by decreasing the viewing angle using a varifocal lens. By doing this we will "bring" the picture closer to ourselves and will be able to consider everything that we need. And an increase in the number of video cameras. Perhaps such a solution will be a little more expensive, but it will certainly solve your problem. And perhaps the price of a pair of 2-megapixel cameras with a viewing angle of 50 ° (for example, "fixes" with a 6mm lens) will be less than the price of one 5- or even 4-megapixel camera with an angle of 100 °. But they will give us much more information about the observed territory.
3. It should be borne in mind that with an increase in the number of pixels without an increase in the physical size of the matrix, it only worsens the sensitivity of the video camera, since the pixel area becomes smaller, and less light falls on its surface.
4. Real high-quality lenses with optics that allow you to get all the advantages of multi-megapixel sensors cost at least $ 1000. What can you expect from a $ 20,000 12MP camera?
5. And the last thing to remember - with an increase in "megapixel" you will additionally overpay for the processing power of the recorded devices, storage devices (HDD), network bandwidth and traffic when browsing the Internet.

P.S. We will continue to test in this way the IP cameras that fall into our hands. Several test samples have already been requested from various vendors with a resolution ranging from 5 to 12 megapixels. Therefore, visit this page periodically for new information on the megapixel race in IP video surveillance.
