- We hope you find our video on megapixel comparison useful. It demonstrates the difference in resolution between cameras at 1 megapixel to 8 megapixels. The cameras used were all made by Hikvision.
The car is about 20M from the camera, which is mounted on the top of the first floor. The lens on the camera is a 2.8-12mm set to about 3.5-4mm.
It was funnier if it became a Lambo at 8MP :)
Or a DeLorean with a flux capacitor?
@@anonUK at 88MP?
it also depends on sensor quality, sometimes a better and big sensor with lower megapixels has far better quality than a higher megapixels. Ex: Canon 1dx mark III has only 20 megapixels and no smartphone in the market gets closer to it , even with a crop image(digital zoom)
I would say 1. Sensor 2. Software 3. Megapixels
@@compactreview 1. Sensor 2. Lens 3. Optical Zoom 4. Software For Up Scaling 5. MegaPixel
@@compactreview sensor comes together with megapixels, so I guess a more precise statements would be: 1. sensor size 2. sensor resolution (megapixels) 3. sensor techhnology (IBIS, CMOS, CCD...) 4. image processing (software) 5. AI (e.g. smart upscaling)
@@compactreview A clean lens helps.
U got a use ur brain abd look at the sensor spexs
Optical zoom would be very effective here. With this camera position, a great lot of pixels are wasted on the building left, sky and building in distance. With a small amount of optical zoom, you would get an improvement equivalent to doubling the MP.
irrelevant, this video is showing the difference between MPs.
It's not a placement tutorial
Zoom is a tradeoff. The more you zoom, the smaller your field of view, which can make all the difference in surveillance camera.
What is with the goofy music? Trying to get a dance party for some middle schoolers?
Lol
how far is that camera mounted that is zooming in on the car? is that using an optical zoom?
I lost my eyesight in an InstaPot explosion when I tried to make a curry sauce... is the music SANDSTORM by DARUDE?
Yet another curry related accident. I lost my whole family by a tragic chicken curry poisoning episode. The music is indeed SANDSTORM by DARUDE!
Правильно выбирайте оптику и не надо бедет этих 5,6Mp. В этой ситуации достаточно 2.1Mp с обьективом 12mm.
Если вы хотите ловить узкий проезд/проход (номера машин, лица), то да, достаточно 2МП и 12мм, но когда вам надо охватить, территорию побольше, то минимум 2.8 и минимум 8МП.
Hi, I'm an AI engineer and I've been playing around with a toy that I've been developing. Can I have your permission to use that footage? I want to see if I can extract the license plate from the lower megapixels but I need your permission, let me know.
Hello friend, I am interested in your work, what is your instagram ?
Thanks for the vid.
excelente video, apartir de 3MP vale la pena actualizarce :)
But what does the same test look like at night? Would love to see if you can reply with a video that shows me.
WHy is this in my recomened LMAO
no one cares if it's in your recommended
Because the tinier the better.
@@user-0r67h2wdhu no one cares about how you think about the comment, god people are so toxic for no reason these days, wheres the humanity bro
Coz it's a good movie :D
It's not only the Megapixel, the lens and software are very important without that the megapixels mean nothing!
thats what you called image processing
The resolution only needs to be good enough to read the license plate & recognize the car make and model and color. Twenty years ago there were lots of digital cameras made by Canon, Kodak, Nikon, and Fuji that only had between 2 and 4 megapixels but had really good picture quality. Notice the big jump in image quality from 1mp to 4mp in this video😀
For CCTV manufactorer like Dahua or Hikvision Keep same lens with Wider Senser so you Can see more Biger view. But not Better Digital Zooming
So if you try 5mp and 8mp of the Same Model series you will not get better Image you will get wider view
To get the benefit of Higher megapixel need to use it with Motorized lense
I'd have loved to see a night time version of this video.
When the light is weak, the optical lens revolution will be low. the 8M has no big difference from the 2M, I want to see night vison too.
Trust me, you don't.
So basically, 2 MP is borderline and 3 MP is sufficient to identify a number plate.
And 8 MP is enough to read it correctly
But if the car is further u need more megapixe to read the plate
@@marianaibelitcariciu5906 Yeah, I'd draw the line at 4 MP just to be sure
most 8MP systems have 12 FPS. Remember and always check that.
But the screen we are watching it on for the average viewer bottoms out at 2 mega pixel or slightly above.
Well 2MP is 1080p and 8MP is 4k in short. Storing those files would be a pain and not all 2MP sensors are the same. For example 1080p footage from different cameras will have different level of detail and this just seems like the same camera at different modes which is not a legible test
What a brilliant idea for a look into different mp.
Very helpful thank you.
@Mister Albert bitrate
bu işte bir yanlışlık var kameranın baktı alan büyümesi gerek miyomum yani
Most CCTV cameras seem to be about 0.5 megapixels, judging by this comparison.

Do not forget frame rate, more camera`s hooked up to the DVR, lower frame rate per camera you probably get
So if you have multiple dvr for multiple camera, that would increase or keep camera st higher frame rate ..?
No, that's not what i said. If you have 1 DVR and its advertised as 60fps, that means for the whole machine, so 1 camera 60fps, 2 cameras 30fps, 4 cameras 15 fps etc...
@@VicGreenBitcoin where i can get dvr 4x camera 60fps?
look for a dvr that can do 240fps at 4K (whit 4 channels), that will cost you some $$.
@@VicGreenBitcoin Was planning to get 4 Channel 4 Cameras, will it be better to get 8 Channel 4 Cameras for this purpose of reserving frames?
Why is this measured in Megapixels, this is video not still photography.
Some security cameras use MJPEG as a video format, also called motion JPEG, works by evaluating each frame of the video, compressing them, and sending them as individual JPEG images.
so you know...
@@rsd3719 Thanks. But that would only make sense if they are indeed stored as individual JPEG files like a still camera would. At least all security systems I came across store their data as a video inside the AVI container using MotionJPEG codec. Anyways, in the end I guess it's just me being a video guy feeling upset by this terminology. Sorry for the rant.
my camera is 48 mp
@WWE Master yep its a quality of my phone camera do you know the song used???
Realme c3 have 5mp front camera and 5i have 8mp front camera now I can choose which is more valiable thx!
Finally. A video about 4K images actually uploaded at 4K! If Hikvision weren't loaded with backdoor Chinese controls and plagued with innumerable security vulnerabilities, I would definitely consider them!
What brand would you recommend? I've been hearing Hikvision are fantastic but obviously they don't tell you the flaws.

@@Tweekend27 Axis for sure.
@@techguy9023 Any other alternatives for those on a lower budget?
multi million dollar companies: THE 1MP ONE!WE HAVE NO MONEY TO GET 8MPS
What are those rings on the roof of the house and is there a way to avoid them?
OMG great comparison. So now I know what I am buying and what to expect.
The greater the megapixels the clearer the image, so best start from 12 megapixel and above.
Music / song is "Adventures" by A Himitsu
The higher the Mp, the more memory intensive it gets. After 5 Mp, it seems like there isn't much difference from the picture quality.
To identify faces in an interior of a house 2 MP is enough but if you need to identify faces or numberplates of motorcycles and cars then 0.4 is the factor to choose the camara MP.
20 meters a 8 MP is enough. FORMULA: MP= Distance [Meters] X 0.4 [factor]
mp is not a measure, focal length of lens matters to.
With my 600mm lens on my photo camera (yes its 24MP full frame) i can shoot a license plate 1KM away :)
i love how in crime movies they always zoom into security footage, as if they could create higher resolution from nothing. (Admittedly interpolation techniques exist, but thats smth different)
Nobody's asking to zoom on for higher resulting. We zoom because its gets closer to what you want to see are you really that dim
@@paddyc20 watch again some movies. Then come back genius.
I like the movies where there look at a reflection in someone’s eye and read what he is looking at.
@@techguy9023 They literally get 2MP from about 10-20 pixels in the image. 😅
Saludos cordiales. Por favor que pantalla monitor me recomienda para un DVR de 5megapixeles y 4 cámaras de igual 5 megapíxeles
Yo tengo una samsung 4k 43 pulgadas
what is the song pls?
Very informative and effective demonstration. Are you using Hikvision software for the playback and zoom-in as well?
So the best is obviously the 8 MP but the best for your money would be the 4 MP
I will be choosing the 5 mp for now. Its really not that much more than 4 mp and i will stay happy with it longer.
5/6/8MP Hik cams are rubbish at night. Best all round cams are the 3/4MP Low Light cams
2mp is actually the best for night vision, so you either put up 2 cameras or buy really good 2mp cameras.
8mp at night is worthless, unless you light up the area like daytime.
@@bobtahoma okay. So which model cameras are you referring to that have large enough sensors to compare to the 2mp Ultra Dahua?
@@bobtahoma do you have any idea how big a sensor has to be for a 4mp camera to be as good as a 2mp? You would have to put a damn micro 4/3 camera on the side of a house to get something of similar quality. An 8mp camera would need a DX sensor in it!
I’m wondering if I could buy 3 dvr cctv camera 8mp and shoot podcast episodes for youtube with high enjoy h quality . Would frame rate suck?
Thanks
Brilliantly useful video thanks a lot for taking the effort to put it together.
لو يمحت لو عايز كميرا هيك فيجن اعرض عليها AV فقط على التلفزيون مباشر تفرق ٥ ميجا او ٢ ميجا ارجو الرد بسرعة وشكرا
Don't rely on megapixels if you are trying to catch the cars no. plates or a person's face in more detail, the lens millimeters plays a role as well, there are various other technologies available like image sensor, wdr etc, that can make a 2mp cam look like a 5mp cam.
how is possible 3Mp is better of 4Mp ??
Very good .... thanks
Literally the same camera used. All done in post.
parece se mejor 3 mp
Ive got the Swann 4k ultra & its impossible to see the vehicle plate number. Stop the lies

Can we use different resolution cameras in same DVR? Like 2 nos of 1 MP cameras and 2 Nos of 2MP cameras?
Yes that's possible
Ez egy jó kamera.

Ez a számú kamera a jó. Hikvision DS-2CE56D0T-IRMF Turret
В любом случае максимум, чем полезна камера - на память останется видео, как угоняют твоё авто. :) Если возле камеры нет 24/7 охранника, такая "секурити" нахер не нужна.
amazing comparision, shorth and get the purpose
dobra dobra nakręćcie to po zmroku. W dzień to i najsłabszy obraz można wyostrzyć.
idiotic comparison, he just downscaled picture
You should mention that we talk about REAL pixels, not upscaled like now is very popular.
@Gaia Technologies music / song name please
So 1 megapixel is as good as any
©️©️were i can get 8 megapixels on Phone android ®️®️
This video fake Because the angle of the camera never moved
Hi. I have hik 5mp cplouvue and mine is no where near this quality. Is there settings I can change
Super video
А если машина поедет не так медленно? Fps надо прокачивать
ты хочеш увидеть номер машины который едет 80+ км/ч? потому-что в 60 км/ч более менее видно на камере с 20 FPS
5MP cammera price
48 mp?
Sony still make a 12MP Sony A7S III camera, which is much much better than any 50/100MP phone camera
Pixel size matters, especially for low light conditions
Hikvision, CP plus,, dahua,,,, which one best??????????????
Hikvision
My schools chrome books record at 0.7 megapixels
в общем купи хоть 100 мр каринка будет говно
Gaia Technologies, did you share this video to be shared on 3part webside?
Короче выше 5 мпикселей смысла уже нет, а так может хватить и 3.
Guy who drives the car:
- Ah shit, here we go again...
А в режиме с инфракрасной подсветкой, все выльется в шумы...
Ну это от матрицы и оптики сильно зависит
how did you zoom? capture only part.
3mp is better than 4😂
One year has passed and nobody answered my question. WTF, hello?
good afternoon, the example you made was with a nvr or dvr.
how can this be an actual comparison between these DIFFERENT cameras??.. The car movement is EXACTLY the same in each "new" recording, so it looks like the video was recorded ONCE (and just played over and over again - so NOT different "takes" of the different models - in which, normally, at each time the new test recording was taken, the car would have to make a new drive-in...). Also the camera's position (and angle of view) is ALSO exactly the same, so one camera could not have been substituted for the next one in line for testing either.. Also, a 5MP camera has a 4:3 aspect ratio, while a 2MP, a 4MP and a 8MP camera has a 16:9 aspect ratio... But in all these different "trials" you show for all the above ("different") cameras, the aspect ratio remains the same (16:9) lol, which is also impossible (since when you were showing the "5 MP" view, the screen's aspect ratio WOULD have changed to 4:3, so it would look more "squared", but, it doesn't do that in your video either...). So it doesn't seem like this is an real comparison at all. :(
This looks like one camera-wide view setting with 8mp capability. The comparison looks like is true base on how resolution work. I can get a 2mp camera with a different lens and it will look completely different. So to compare megapixels you have to use the same camera. The different cameras will have different lense different qualities. If you want a wide view and capture as much detail as you could get the max resolution camera could. If you just want detail in a single spot like a license plate, then just get the zoom 2mp and zoom in one spot and it works better than 12mp. The long optical tele-zoom lens is way more expensive than all these high megapixels.
ALL seemed to be the same🤣🤣🤣🤣🤣

2mp and 5mp how to set bitrate streeem
megapixels are not needed. The quality depends on the size of the matrix
thank for the info going to install cctv camera but the guy telling me where to install 2mp an where to install 5mp but the higher you go is more money now i see why he say to put the 5mp facing the road u can see number plate clearer from 5mp .
5 മെഗാ പിക്സൽ ക്യാമറക്ക് എത്രയാണ് വില
This is ridiculously misleading. There are a lot of professional cameras that cost thousands and have 8mp and less, yet they don’t shoot cctv quality. You have to take in many factors, and sometimes fewer mp is better.
3MP and 2K any difference then?
I feel like a 5 megapixel would be perfect for a camera
I don't see much difference between 1MP and 8MP, only the price. 8MP is 4K, right?
Mot on this car ran out on the 17th November this year.
while mean smarts phones with 100MP lol
What about prize in any camera
So cheap if TVI system.
That's is good video,would be good to see it night time . This is more important ,especially reading reg.numbers
This video, analog cam or IP cam ?
Now, that's a comparison.
Thank you very much!
'
depend on brand of camera / videocamera made
1, 2, 3, 4 and 5 sucks.... only 8 is "decent"... so sad...
I think one KEY detail is with the size of the lens the test/video was done, they did it with 3.5-4mm. I got a 8MP camera with 2.8mm lens and the image captured is not better than the one of 1MP of the video.
object distance vs focal length of the lens. Its % of the total image that matters. If you use a 2.8 at the same distance then no, it will not be better then their 4mm at the same distance due to the zoomed in image of the sensor due to= the lens. But your 2.8 8MP will be better then the same 2.8 2MP image
What about the DISTANCE, was it the same as in the video?
Also, VERY IMPORTANT: are you using a brand camera or some no-brand, because no brand cameras falsely advertise their resolution - I'd had a supposedly 2MP no-brand camera, and its actual resolution was 640x360 (0.23MP!!) instead of 1920x1080 (2MP).
3MP sharper than 4MP? You need to tuning the focus.
